Adjustable wheel jig designs

Go_Time Monday, 12/3/2018

Hello All, I have been lerking on this site for a while now and just recently made an account.  I have seen a few wheel jig designs and they all look great!  So I thought I would share my design for an adjustable wheel jig.  It is a super simple design and slides in and out to accomodate any size HW.  Enjoy!

Nice work! I need to make myself a new jig. I like that your one side is fixe and you just slide the other.

That’s something I need to work on. I had rows of pencils glued together. Now I just use 2 sets of 2 pencils glued together and line them up the best I can along a piece of lined paper. It’s not at all ideal but I think they mostly roll straight afterwards. Lol. Great design!

  • Simple yet effective. Made out of 3/4 inch MDF. 3 1/2 inches Wide x 8 3/4 inches Long. Two adjustable bases with dowels (2 x 3 inches). Strips are 3/4 x 8 3/4 inches — 41-14
  • Very nice. Nice a hefty. — redlinederby

Ok... I feel stupid asking this.... but here we go...

What is the purpose of these jigs?

  • It aligns the axels straight in the chassis. — LeagueofSpeed
  • And more so, keeps both axles straight relative to themselves. — redlinederby
  • Huh.. ain't that quite the idea. — CalgaryDiecastRacing
  • Cars that runs straight ( less bouncing from side to side) produces more speed. Every fraction of a second counts. — 41-14

I made this one for castings that won't sit properly in a standard flat top jig.

Cool, I had forgotten all about this thread.  I have updated my jig a couple of times since the original post. This is version 3.0...or 4.0 cant remember. Hope it helps.

This is by far the best jig ive made so far.  And the red hash marks really help believe it or not.

This is a picture of the jig designed by Red Pill Racing

I took it one step further and designed an outer frame to square up the wheels


You can see the front wheels are at 1.2 inches

As are the rear axles.

If you put a little thought into it, it's pretty easy to design one yourself.

  • Good idea with the rubber bands — redlinederby
  • Those aren't rubber bands. They're Variable Tension Axle Stabilizers. — Peter_Bee
  • They are indeed Variable tension Axle Stabilizers! Ask for them by name at your local Walmart. Lol — Red_Pill-Racing
