I bolted my jig to the wall of my shed

[Mark Bulgier]

I know, big whoop, right?  But I am happy with how it turned out.

I bought the jig that Corrie Martin listed on this list a few weeks ago.  Finally got it mounted on the wall, where it doesn't take up much of my tiny work space. Corrie's stand for it was awesome, with three wide-spaced legs on wheels, but I didn't have room for it.

I wasn't even going to use a jig. I was all set to build a frame using just V-blocks laid on a horizontal flattish piece of steel. Welder's magnets to hold the V-blocks in position. Tubes just laid in the V-blocks, with something heavy laid on top of them to hold them down. I know that would have been fine, but it's slow and annoying once you've grown accustomed to a proper jig.

This one isn't my dream jig, not optimized for ease of use, but it's plenty precise and rigid.

One part is missing, yet to be built: A tower to hold the top of the seat tube, with a sliding "dummy seatpost".  Like a lightweight lathe tailstock.  Next project.

Corrie supplied it with three bocks to hold the ST, DT and TT near their middles (not shown), which is not how I like to jig a frame.

Mark-

You are a maniac! Nice work! I really want you to make some Rube Goldberg linkage so that you can adjust the stand tension from the jig side of the wall. Maybe convert it to a foot operated pnuematic clamp?
