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

http://www.eurospares.com/graphics.htm

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

cheers,
Michael

Here are 2 websites with plans for a frame jig:

http://www.custom-choppers-quide.com/motorcycle-frame-jig-blue-prints.html

&

http://www.crimescenechoppers.com

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...
