FRAME FIXTURE

. . . the making of XC FS racing machine - STEREO . . .

I started thinking about the supporting frame or the rig for welding the actual bike frame. It is commonly known the very much of the frames quality depends on the quality of the weldment. So there is deffinitly a need for a good frame fixture. This tast will not be easy as there is a need for quite small tolerances and the structure itself must be very rigid. I'm also trying to make this an adjustalbe construction so that the head and seat tube angles and lengths may be changed. Although as I am building a FS frame, I'm beginning to think that I only need this rig for the first part of the frame (for welding the head tube, top tube and seat tube) because the rear end will be linked through pivots, so no welding there. On the second thought it may become to building a totally new rig for the rear triangle.

I searched the web for the rigs but all I came up was company called Anvil Bikeworks. The rigs they make are very beautiful work of art but I am definitely trying to make a much simpler and cheaper rig, but with all the necessary adjustments. So no place to copy:) Must deign everything by myself. I just need to see that I don't waste too much time and energy on it as this is not the main topic...

Here is a little preview what I have already made, but it has too many faults, so I must redesign...
