This little blog is to supplement my project labelled ’Meet “Arty” my little articulated friend.’ which should have been or will be “projected” shortly.

A brief word about the author…. I am currently chair ridden due to a sprained ankle so I can only channel my “talents” to typographic mistakes rather than woodworking ones and thereby inundate LJ with my verbal diarrhea.

As the “Arty” project briefly discusses “nuts”, this is a self taken impromptu picture of a nut (without my consent and before my haircut and shave) holding “Arty”.

(Feel free to use the above picture as a “bad example” to discipline unruly kids.)

The following is the cutting of the practice MDF wheel and not following T&J wheel making procedures brings out the rebel side of me. Rather than drill 1/4 hole into the proposed wheel and then retro drill out for the rim, I drill out for the rim and use a spacer to mount the “wheel” onto a 1/4 dowel. I used to make the spacer out of timber, however, since acquiring a 3D printer I print the spacers and that way they are perfectly repeatable and can be incrementally modified to fit with just minimal plastic wastage (and NO shavings to clean up).

The jig used is a ‘micro gear’ adjustable circle cutting jig that was designed using Sketchup, then laser cut and glued (no woodworking tools used other than clamps and definitely no animals harmed).
The same spacer was used to cut the treads (omit the spacer for the inner half wheel without the rim),

Below is another SU designed, laser cut jig and was used to sand the angles on the treads. The jig is micro adjustable and designed to fit onto the circle cutting jig and will accommodate various sizes and type of shop made wheels. The one pictured is sitting on my first design of the circle cutter.

This following picture is to prove it works on real timber as well as MDF.

Though old hat, for those that don’t know how to easily “turn” small gear levers,
Drill hole in proposed knob for shaft,

Glue in over length shaft, trim knob, mount in drill,

Shape knob using spinning drill and sand papep.


(Captions for the visually impaired.)
I also use the laser to cut templates for perfect positioning of small parts that are difficult to clamp (even with short pipe clamps). You (as in U) may be able to hold it till the glue dries but I can’t (even using superglue). This way I can drink and glue…

(Hint the laser cut, charred MDF template is not the “small parts”.)

Thanks for watching, now I’m off to project “Arty” otherwise this addendum would be an orphaned addendum and I’d have to delete it.

Thanks ducky!
Very interesting and will be quite help full in making jigs.
I had the idea of a sliding jig for the drum sander but much cruder built before I got the SS.
Love your tire making out fit.
Why have you waited so long to show us your stuff?

As Cruijff already said: “Every disadvantage has it’s advantage”

The benefit of your sprained ankle is that we can read this nice blog. Thanks and keep on going,

I enjoy your writing style, and wood working is great also.

Thanks Knife, Twist your ankle, buy a dictionary and your articles would be on the cutting edge as well.

All you need to do is take a photo of a s l o w moving snail (that way you don’t need to worry about camera’s ISO settings) and just ramble on.

Thanks everyone for kind comments.

Don’t get intimidated by the person in the picture. It’s just a picture of my timid wife, so feel free to be harsh with your critiques.
