Chop Source - Frame Jig Kits and Neck Centering Cones (motorcycle frame jig parts)

I have assembly instructions available with drawings like this. They are higher quality in the instructions.

 
Travis,

I received my rotisserie kit. Thank you for your prompt shipment. Everything arrived in good shape and the components appear to be well made. I'll post some pics of how they retro-fit to my existing jig when mods are done. It may take a while though.

Thanks again for this awesome kit. Nice work.
 
awesome travis- looks beautiful. i'll be ordering one asap from ya.

cheers- michael

also, got my shop in denver now and will be talking to you more on ad space and other stuff we talked about before.
 
There seems to be some parts on the Assembly Drawing that are not in the other photos…



There is a piece of angle to the outside of the post clamps on either end, and the item almost dead centre next to the bottom motor mount support.

Another question on the axle plate bracket there are three sets of slots is this decorative or for different axel size set ups?

With the height you have gone for 38" in the up rights for the base, the voodoo vintage jig is only 28" is one for standing vs seated welding?? Is the extra height needed for the full 360Deg rotation???






This is the full kit with all of the upgrades:

With your jig rails at 72", you loose some each end with the uprights, what is the maximum amount of stretch you could add to the frame?

That's a common question. If you flip the axle plate fixture around to the back side of the upright (I should have had it that way for the pictures), you can stretch an XS650 frame about 11". Without the rotisserie stand you could stretch it 17". 6' main rails work well for most types of frames. If you're building a drag bike or something long then you'll want to make your rails for the jig and stand longer. One of the nice things about a bolt together jig is that you can easily make the jig longer by buying new rails for the jig and frame. You won't have to cut your jig apart and then weld it back together.

Another question on the axle plate bracket there are three sets of slots is this decorative or for different axel size set ups?

The slot sizes are 5/8", 3/4", and 1" to be used with commonly available threaded rod of those same sizes. The 5/8" threaded rod is used for 17mm axle plates, the 3/4" is used with 3/4" and 20mm axle plates, and the 1" is used with 1" and 25mm axle plates.

With the height you have gone for 38" in the up rights for the base, the voodoo vintage jig is only 28" is one for standing vs seated welding?? Is the extra height needed for the full 360Deg rotation???

You can make it as high as you want. I used 38" because that allowed for 360 degree rotation of most stock frames. That being said, you don't need a frame to rotate 360 degrees to benefit from the rotisserie.
 
Thanks Travis,
I figured out some of the info from rereading back through the thread, but this is a more detailed explanation again.

Be good to see the jig with some sample photos of a common weldon kit.
 
Here's an XS650 frame in the full kit after the various spacers have been cut to size:

What is the ride height for the frame using this jig and central mount? is it at the top of the rails, bottom of the rails or the level the feet touch?
 
Would that kit work on a car rotisserie or would I have to make a the same set up that u guys used

You might be able to make it work with some customizations. I guess it depends on the car rotisserie.

What is the ride height for the frame using this jig and central mount? is it at the top of the rails, bottom of the rails or the level the feet touch?

The center fixture puts the bottom of the frame 3" above the main rails on the jig. If you use 2"x3" tube for your main rails, it is 6" from the bottom of the frame to the bottom of the main rails of the jig. Ride height is all relative. With a hardtail, move the axle plate fixture up to the lower the bike. The height of the center fixture doesn't really matter. I suggest taking several measurements on the stock bike before taking it apart. Knowing the height of the axle, neck, and lower engine mount may be helpful.
 
As of 1/27/13, the cost for international flat-rate boxes just went up about 25% :banghead: :thumbsdown: :mad:

So unfortunately, it just got a little more expensive to ship these internationally...
 
Yeah it was a big hike from USPS. Normally the prices go up just a little at a time so I don't even pay attention to it. This time I had a bunch of flat rate boxes going to Canada and overseas and didn't them get them shipping out before the rate hike. Lost about $100 because of it.
