Frame Alignment and Fixturing Table
Using a Bridgeport 9x36 milling table, bits of 80/20, and homemade parts to construct a bicycle frame tacking fixture and alignment jig.
The milling table was Brandon Ives idea and it seems like it'll be a good solution. I bought this one used for $40 (the freight cost 3x that). It's flat and the t-slots are very helpful for fixturing items in place.

Close up of some of the items. From left to right:
* Start of an alignment block. The dummy axle is 135mm.
* A piece of 80/20 (1020 extrusion) with a seatpost centering cone mounted on it. You'll see how this fits together once I get the rest of my 80/20 bits.
* Another cone, this will end up being used for the headtube.
* Dummy headsets. A 7/8" steel bar fits inside to be used for alignment purposes.
* Bottom bracket post for frame alignment. The same two handles can be used in the post or nut.
