View Full Version : Motorcycle Frame Jig

06-12-2011, 08:22 PM
I am looking for examples of a Motorcycle Frame Jig. I have done a search and found a couple of old posts, but the pictures are not coming up on them.

I am looking for a specific type of jig, one that uses a surface plate style instead of a tube construction.

I think I would like to go with a 16" X 96" X 1" plate with holes drilled and tapped every 4" for assorted jigs and brackets.

Any pics or help would be appreciated.

should be many places out by you to get a t-slot table from old machinery. that would work just as good. Them you can use long leg angle plate to hold neck tube. Ive seen this at voodoo choppers a couple of years ago. quite the set up.

Another possibility if you can locate one might be a laser table. These are super flat with 1/4-20 tapped holes on 1" centers.

You might be very disapionted as to flatness of stated 1" plate , Even if it starts flat do not weld to it it will warp

Hey Buddy :)
Had to take a look around their site before I found the jig... I see they have a Bamm Bamm and a Mech Hammer too :cool: ;) :D

Here's the jig:

The IronPit one is very pretty looking but I would have thought that they might want more mass.

If you look around on this page of my website


you'll find photos of my fixture and some used by various commercial race frame builders.

Here are 2 websites with plans for a frame jig:




The first one is $19.95 & the second one is a FREE DOWNLOAD. I hope this helps. The one from Crimescene choppers is shown being built on Ron Covell's new "Building A Chopper Chassis" video.

Have a blessed day & good luck on your build. Kent

Well, sorry it has taken me so long to get back on this topic. I have been busy moving tools into my new shop.

I purchased a 2' X 8' X 1" A36 Plate. And as it figures, it is not flat (lol).

I am wanting to have it surface ground and then I plan on bolting it to the frame so as not to warp it.

Is there a standard for tolerance on the grinding?

Sorry for my inexperience...

You need to find someone with a big Blanchard grinder. Ask them to "grind it to clean". This is the fastest, cheapest way to precision grind a surface. There was a shop in Denver that had a machine big enough to grind a 5' by 10' welding table frame. The frame was then covered with a precision aluminum plate 1/2" X6' X12'.

Or find a shop that has a planer.

A friend of mine made a new welding table for his shop (he's a machinist/fabricator who does jobs that require a lot of accuracy/precision) and had a local shop surface the top plate on their (probably 70+ year old) planer. He said the planer looked long overdue for scrapping, but the top was square as square could be, and my friend is an EXTREMELY picky high-end tool-junky kind of person.

I think the table on my Tree (TOS) 425 mill was planed:


so that gives you an idea of what a planed surface might look like.

Thanks for your responses guys.

I am currently trying to find a company here in Ohio to Blanchard Grind the plate as well as mill the edges and drill and tap some holes.

I have conatcted several companies, but they do not seem to be interested in doing the one piece.

I am shooting for a jig similiar to the Voodoo Choppers one in this thread.

I'll keep you posted on the progress...
