Step-by-step carving of a dinosaur marionette

Step-by-step carving of a dinosaur marionetteWez Champion is documenting his efforts as he makes a very cool dinosaur marionette. Champion says he is a fan of the Prague style of marionette making.

Says the artist:
One of the things I like most about ALL Prague puppets is the way they don't try to hide the fact that they are made from wood... the master craftsmen seem to use the straight edges of chisel cuts to form unique facial expressions and unbelievable style to each character...this is what I someday hope to master for myself!

His blog posts document his project from drawings to roughing out the figure, to carving details. Stay tuned as he goes on to paint and assemble the puppet.

Here is a link to Wez's World -- the blog that documents the making of a marionette.

The Complete Modern Blacksmith book

The Complete Modern Blacksmith book
I recently gave this book to a friend for his birthday. An anthology of three out-of-print books, this book is a great value. The book covers much of what you might expect from a book with this title. What makes it really cool is its emphasis on making, repairing, and maintaining useful tools of every sort. I haven't found this information elsewhere yet. Very nice pencil drawings accompany the text. If you want to take your "making skills" to the next level, you should check this book out.

Here's amazon's info page on The Complete Modern Blacksmith.

Automata-making workshops in Portland, OR

Karin Gale -- one of the creators of The Raven automaton I posted about some time ago -- will be hosting a mechanical bird automaton workshop in Portland, Oregon in a couple of weeks and still has a few spaces left.

Karin writes:
"These are not advanced workshops from a mechanical perspective so it would appeal to beginner level automata makers for this reason. But advanced makers might benefit from our construction techniques which allows a lot more freedom than some of the traditional automata construction methods using wood and metals."

How to make a super accurate vernier protractor

How to make a super accurate vernier protractor
Check out this cool DIY article by Steve Garrison on how to make a protractor accurate up to 0.1 degree.

How it Works (from Steve's site):
Since this protractor uses a bubble level it can only measure vertical angles. The bubble is zeroed up on a reference surface by rotating the disc that the vial is attached to until the bubble is aligned with a mark and the front wing-nut is locked down. Then the protractor is placed on a tilted surface and the larger disc is unlocked (using the wingnut on the back) and the disc is rotated until the bubble is again aligned in the same position, then the rear wingnut is locked back down. The angle is read to a degree where the long line on the left side of the vernier points to the degree scale - read the smaller number. The angle is then read to a tenth of a degree by seeing which of the vernier lines matches up best end-to-end with the degree markings and added to the degree measurement. The markings on the vernier are 0.9 degree apart.

Here is the link with details on how to make your own compact protractor accurate up to 0.1 degree.

Video of paper prototyping a griffin automaton

Katy Hargrove has created a great video in which she describes the process she is using to prototype an automaton project. Using manila folders, paper clips, scotch tap, and metal paper-fasteners, she has managed to create a very interesting motion for her griffin project. This is a great demonstration of an easy and effective process for working out the proportions and motions for various automata figures.

Check out more of her projects on the Art by Katy Hargrove blog.

Building a real woodworker's workbench

Here is a great Instructable on how to build a high-quality woodworking bench based on a set of plans originally published in Fine Woodworking Magazine (the best magazine of its kind, in my opinion).

The design used here is simplification of a bench from Sam Allen's book Making Workbenches.

Proxxon 38481 IB/E Professional Rotary Tool

Proxxon 38481 IB/E Professional Rotary Tool
While most of us are familiar with the versatile rotary tool, we tend to equate it with the Dremel brand name. I have owned many, many Dremel tools and do not have any serious complaints.

Still, this Proxxon profession model appears to offer some noticeable improvements. The manufacturer claims that this model can be use for extended periods when polishing, grinding, cleaning and engraving -- without becoming overheated. That is one problem I have had in the past, but I think I pushed the poor Dremel too far.

Like the better models of Dremel rotary tools, this Proxxon can be run at a range of speeds from 5,000 to 20,000 RPMs. Variable speed is a an important feature in any make of rotary tool.

Finally, the Proxxon features a die cast aluminum head which serves as a study housing for the steel spindle, running within a ball bearing assembly. This strikes me as more robust than most Dremel tools.

The unit comes with six collets (sized 1/32", 1/16", 5/64", 3/32", 7/64" and 1/8") and is compatible with a number of Proxxon accessories such as a foot switch, flexible shaft, and drill stand.

Here is a link to the Proxxon 38481 IB/E Professional Rotary Tool


Note: Those of you who know you will be using a rotary tool a lot, should consider something like the Foredom rotary tools that jewelers and serious woodcarvers use.

Carving tools sets with interesting handle design

Carving tools sets with interesting handle design
I've used the traditional carving knives, chip carving knives, and palm carving tools, but I can't say I've ever used a carving knife with this style of handle.

I gather that the handle design is meant to serve two purposes. They can be held fully in the palm for larger, forceful cuts, or griped by the narrow part at the neck -- rather like a pencil -- for finer cuts. It sure sounds like a good idea.

Woodcraft has a seven piece set (shown here, $50) and a a five piece set ($40). Both come in a storage box of some sort.

Micro carving tools for very small wood carvings

Dockyard micro carving tools for small wood carving
The other day I mentioned the Rick Bütz woodcarving knives I use. While about 70 percent of the time I use either the standard carving knife or the detail knife, there are times when a specially shaped carving tool is just what you need. For a long time, I struggled with a mediocre set of palm carving tools. Mine didn't hold an edge very well and were just too big to be very useful.

A few years ago I discovered these unassuming little micro carving tools. They may look simple but they are hand forged, tempered, and tested for a correct edge profile. Not only that: they come sharpened and ready to use. Hallelujah!

They offer sets like the one shown here in three different sizes -- 1.5mm, 2mm, and 3mm. I went with the 2mm and am very happy with it. The micro carving tool set I bought has single and double bevel chisels, a skew chisel, a 90 degree V-shaped tool, and U-shaped gouge. All in cherry wood handles.

Here's the full line of Dockyard micro carving tools.

Miniature woodshop models with amazing detail

Miniature woodshop with amazing detail
Setting the scene for an automaton often requires making miniature versions of things. Having done bit of this myself, I can really appreciate the work of David Brookshaw who makes 1/12-scale miniatures of tools and workshop equipment.

Brookshaw is working on a fully-equipped Victorian workshop. In the photo above that is a U.S. Quarter clamped to the bench vise!

You can visit David Brookshaw's web site to see more photos of his work

Making amazing wooden gears

Here are some samples of gears made by Steve Garrison. He has developed a technique that enables you to make any of the gears of the type shown in this video by using either a scrollsaw or a tablesaw. You can make straight-tooth or helical gears.

From his description:
There are no paper patterns to glue to wood and saw around, the correct involute tooth profile is automatically generated. This technique is very simple once you see how it works. There is no need for expensive cnc routers or lasers or any computer-controlled tools. If you have a scrollsaw or tablesaw, the ability to cut accurately sized circles from plywood, and a computer - then you can do this. You won't find this technique anywhere else, I have looked thoroughly and know it is my own original idea.

Visit his web site at http://www.stevengarrison.com/ from that home page click on the "gears" link to purchase Steve's technique. The price is $30.

How to Make a Circle Cutting Jig for a Router

Circle Cutting Jig for the Router
Perhaps you've been inspired to make a wooden machine with some rather large pin-wheel type gears. There are many ways to cut circles including freehand on a scroll saw or band saw. You can also make or buy a circle cutting jig for the bandsaw. Additionally, you can consider using a fly type circle cutter or using a hole saw in a drill press.

Here is a complete article on how to make your own adjustable circle-cutting jig for a hand held router.

Unlike many a circle-cutting jig for the router, this one overcomes a common limitation -- cutting a circle with a radius shorter than the distance between the router bit and the pivot on which is spins.

John English came up with the ingenious jig you see in the photo above. It doesn't rely on a pivot point, which means it can be used to cut range of circle sizes.

Carving Facial Expressions Book

Carving Facial Expressions Book
Here is a short book covering the details of carving the human face, showing a range of emotions. Though only 64 pages long, it includes details on the muscles of the face and some step-by-step examples of carvings. There are also reference photographs to serve as the basis for your own carvings. The author's obvious skill is enviable.

At about $10 USD new, I think you might want to consider getting the book Carving Facial Expressions.

For those more interested in carving caricatures, check out Dave Stetson' book Caricature Carving from Head to Toe and Pete LeClair's book Carving Caricature Head & Faces.

Wooden Clock Wheel Cutting - Bandsaw Pinions

Here is a great video with detailed instructions on how to cut small clock pinion gears from plywood using a band saw -- an alternative to the more commonly used scroll saw. I own this small, well-rated, affordable benchtop bandsaw.

The craftsman in the film uses a fairly wide band saw blade -- 3/8 inch perhaps. Despite its large sized, he shows how to used a series of straight cuts and the front of the blade to nibble away and tight and curved area.

He does turn to the scroll saw, not for cutting, but for filing the edges of the pinion smooth. He mounts a needle file into the scroll saw. You can also buy files designed to fit in the scroll saw.

The video also shows how to use a benchtop disk sander to create round spacers and how to best glue the parts together with white PVA glue.

This is the kind of education you can only get by watching someone with experience.

Screw & Bold Removers, Screw Extractors & Plugs

I hate to admit it, but even I mess up sometimes. A lot, actually. I use mostly brass screws, and they can strip easily if I use a cordless drill to drive them. Here are two options for saving the day. I own both. I NEED both.

ProGrabit Screw and Bold RemoverThe first is the ProGrabit Screw and Bolt Remover. I use this piece when I have stripped the head of a phillips head screw. This 3 piece kit contains everything you need to remove screws (sizes 4 thru 14) and small bolts.

To use it you, place the appropriate sized extraction tool in you drill in and run it in reverse to create a cavity in the screw or bolt head. You then flip the extraction tool in your drill so that the screw end can be inserted into the cavity. Again, running the drill in reverse, you back-out the screw or bolt.

Screw Extractor for Broken Headed ScrewsThe second option is the Cut-around Screw Extractor. I use this when I have snapped the screw head off of the screw completely.

You simply chuck this miniature hole saw into your drill, center it over your broken screw, then cut a plug out of the wood with the embedded broken screw in it.

Tapered Plug CuttersWhen finished, you have a nice clean hole where your mistake once was. You can then plug the hole with standard size dowels or plugs cut with a tapered plug cutter. Cutting your own plugs will allow you to match the wood type, color and grain closely if you have some scraps from which to cut the plugs.

Aging an Authentic Working Wood Catapult Kit

This is the second in a two part series reviewing the working wood catapult model made by Pathfinders. In the the first part, I reviewed the the kit and gave you some assembly tips. In this part, I'll tell you how I went about making the catapult look like it truly belongs on a medieval battlefield.


What is the Kit and Where Do You Get It?
The catapult kit is sold by ThinkGeek.com by the name of "Wooden War Engine Kits". ThinkGeek.com offers more than one model; this article refers to the one advertised as "Catapult Kit". It sells for $19.99.

Getting Ready to Get Old
Once the kit is assembled, you should have a bit of fun testing it out. I recommend throwing small grapes at a pyramid of empty aluminum cans. If you would like to make your catapult look old, read on. For this process, I used the following tools and materials:

* Carving knife
* Small wire brush
* Furniture finish touch-up markers
* Coarse twine
* Elmer's glue
* Sandpaper - 100 grit
* Minwax wood stain - Early American
* Round wooden disks
* Wooden wheel pegs
* Popsicle type "craft" sticks
* Soldering iron with wood-burning tip
* Gun bluing
* Portable hand drill
* Ball-peen hammer

None of these things are essential. You should feel free to use whatever tools and materials you have on hand or can obtain easily.

Making the Catapult's Wood Beams Look Old
The first thing I did was removed the string and washers from the model.

I used a carving knife to take the corners off of the straight edges of the wood. I didn't remove a lot of material because I didn't want to compromise the strength of the wood.

I just shaved off small, irregular shavings to make it look a little less perfect and perhaps as if the beams had been hand-hewn. I also rounded the spoon-shaped end of the throwing arm.

Next, I added the wood knots to the beams. I have a set of three wood finish touch up markers. I used the second darkest color. By gently resting the very tip of the marker on the unfinished wood, pigment from the marker is drawn into the wood fibers in a way that looks something like a real wood knot. Use the underside of the model to perfect your technique.

The knots may look a little too dark at this point, but don't worry. After placing knots of various sizes on the beams, I gave the entire model a coat of Minwax wood stain. I used "Early American" simply because I had some around. You can use whatever color you like, so long as it is considerably lighter than the knots you have made with the marker. This allows the knots to show through the stain. At this point, you should give your catapult some time to dry.

Later, I used a wire brush to give the catapult some scratches and wear marks to make it look like it had been used for years. I also used a wood-burning tool to add some grain lines and cracks to some of the beams. Make sure these lines follow the grain of the wood so that they appear natural.

I dipped the the string that comes with the kit in the Minwax and wiped the excess off with a rag. This makes the "rope" look old too.

Adding the Twine to the Crossbar and Throwing Arm
I am not sure if it is authentic or not, but I thought some cordage wrapped around the throwing arm and crossbar would look good. I also figured this would provide a bit of cushioning. I used a coarse three strand twine for this. I unraveled the strands so that I had a single strand. I tied one end of twine around the crossbar.

Next, I spread some Elmer's glue on the section where the twine was to be placed. I then wrapped the twine in a tight coil around the crossbar. I tied off the end and put a drop of glue on it to keep if from coming off.

This process was repeated on the throwing arm where it meets with the crossbar.

Making the Wooden Wheels for Your Siege Engine
I purchased a set of round hardwood discs that are 2 - 3/4 inches in diameter. I also purchased some wooden toy axle pegs and some craft sticks -- really they are just Popsicle sticks. All three items can be found at craft stores.

I used a soldering iron with a flat wood burning tip to create parallel lines on the wheels to make it seem as if they were constructed from individual planks. I also burned the edges of the wheels a bit to simulate wear and wood grain.

Next, I glued two short lengths of Popsicle sticks to the outside of each wheel to model the boards that would hold the wheels together.

I drilled a 1/4 inch hole in the center of each wheel and in the four corners of the catapult base. I sanded flat sides on the axle pegs and darkened them with marker.

Using the toy axle pegs, I mounted each wheel to the catapult. I glued only the holes into which the pegs go, so the wheels can move freely. Finally, I gave the wheels a coat of wood stain.

Finishing Touches to The Antiqued Catapult
The catapult was starting to look pretty old at this point, but the bright metal washers on the outside ruined the effect. I used the rounded end of a ball-peen hammer to dent one face of each washer. I then rubbed some gun bluing on the surface to give it a dark, oxidized look. DO NOT get this stuff on your tools.

In the end, I spent 30 to 40 minutes making the basic functioning catapult kit, and 4+ hours making it look old! I had a lot of fun doing it.

Where to Get the Kit and Other Supplies
Most of what you need can be found at your local hardware store, craft store, or hobby shop. If you have any difficulty finding these items locally, here are some online sources:

* Catapult kit
* Wood carving knife
* STEEL SCRATCH BRUSH
* Sharpie Touch up Markers - 3 pack
* Sisal Twine
* Elmer's Glue-All
* 100 Grit Sanding Sheets
* Minwax Wood Finish - Early American
* Wood toy wheels
* Wood toy wheel axle pegs
* Cuisipro Frozen Pop Sticks
* Woodburning and soldering tool set
* Perma Blue, liquid gun blue kit
* Cordless drill
* Ball peen hammer
