« Part 64: Finishing Up the ????? Train Car Part 65 of Toy costruction series Part 66: Hummer Wheels Jig Part 2 & 3 »

Got the plans for the Hummer and it’s about time to give it a try.
There are some outstanding Hummer projects on here so have lots a great examples to look to for inspiration.

The first thing up for modding is going to be the wheels.
This is the main reason I’m building this, been wanting to make some of those mudder tires. LOL

I’m afraid I’m like Ducky there’s just something about a cool set a wheels!!!

What got me started was seeing a post about building the jig for the tires over at woodworkforums.
http://www.woodworkforums.com/f174/wheel-jig-206333

Here’s what it’s all about.

His jig and the one I made are based off the jig that comes with the Toys And Joys plans.

The miter gauge is set at 60 degrees for this project.

As always there’s a hundred ways to do this but this is just one of them.

First up is to build a toothed indexing wheel to be used to set the distance between the treads, this is the same size as the tire 4 1/4”
Here is the wheel and indexer taped together after the tread had been cut..

First copy, print, then cut the wheel pattern off the plans to some 3/4 plywood[I used particleboard don’t]and make a wheel pattern.
[The cuts for the treads are set for 10 degrees]

Then as you can see in the picture made a jig using my sliding fence, there is a hole drilled down through the top plywood brace into the center of the wheel pattern and a dowel is used to make a pivot point.

When I screwed the plywood down to the sled to hold the wheel bracket it was so tight that it was hard to turn the wheel for the next cut so worked out really nice and safe for the cutting.

Now with this set up you can cut the grooves for our indexing wheel.

Now make the 8 wheel halves and centers. [make extras]

Now some shots of the miter gauge set up.


Here you can see a bolt locked to the miter gauge arm so now you can place the indexing wheel we made and a wheel blank, lock them down to cut.
You can see above this is an indexing lock that works with the wheel we made to adjust where the treads will be cut.
The lock is adjustable so you can set how far it seats in the wheel.

[Remember when your setting up for the cut the center of the tire is what needs to center the blade]

If I do this again I’ll make the lock pointer smaller.

The numbers on the indexer are there to help me not miss any grooves.

You need to loosen the tire to move to the next groove so I used double sided tape to keep the tire and indexing wheels in line.


You may need to use a backer board to keep from having tearout.


I know there’s more that could be added but maybe this will help some one.

Tomorrow we’ll get to the fun stuff.

#4, you remind me of the fairy tale ”The Princess and the Pea”. It’s not that you are a Princess or you pee a lot but you must walk on lawn seeds as you don’t let the ”grass grow under your feet”.

Nice jig… watch out for the lightning as you’ve already stolen my thunder (I’m working on one as well, from the same article… good take.)

From what I’ve seen of your other jigs it will be much better than the one use jig I made.
Sorry Ducky I had no idea you had something in the works.
I already had one in mind before his post, it just kinda pushed me over the edge to get er done.
What are you making the wheels for may I ask.
You’ve already made the Hummer and I was thinking you were on a construction project?

That new Power Wagon sure looks sweet and would be a fun build.
Again sorry!!!

Actually you’ve given me a few more ideas re the jig. It was actually Dallas diagrams that got me going as I thought I had an ally in another Sketchup user (unfortunately he’s one of those weird CAD culture followers).

I have already made the wheels for the front end loader I started before the gummy ankle, but as you, I have always considered a generic jig but was too lazy to design. Dallas’ (and your ) contributions gave me something to plagerise and as I have enough plans to ensure I will need to make more wheels, Iit’s just another excuse to use SketchUp (and keep out from under the missus’ feet). Just finishing the import of the Backhoe Tractor so after that the PC would only be boat anchor fodder otherwise.

Making the jigs might be the best part. I took a small table saw and dedicated it to my wheel jig’s. Changing blades and having it dedicated doesn’t tie up my Unisaw. Have fun, keep posting. Sharing ideas is fun.

I certainly would like a looksee atit. However, rather than kidnap this blog for out nefarious deeds, any chance of posting under Dutchy's gallery and keep it where we can all remember. Until our chest beating thread gets launced, we might as well link the hints there so we have them grouped in one place for quick access, unless there are better interim ideas. Anyway it’ll give Dutchy something to do when he gets back from his dirty weekend…

You’re right on the money there hunter71. I have as much fun on here trying very hard to make myself come across in a logical manner as I do trying to get the wood to do my bidding. lol

It’s funny but Ducky it was your beautiful jigs that got me thinking about a wheel jig then I saw Dallas’s it put me in high gear to get er done.
I had been putting off the Hummer but you two got my mind in the right place to tackle it.

And Ducky I hope you will let me in on the plans when they come to fruit or is it a vegetable?.
