Bentech Step 2-1/8

Main tube with head tube clamped in the jig.
The drill thing is what I used to drill the hole for the head tube.
White u-strip will be welded on for the idler wheels
to get the chain up and out of the way of the front fork.

Here the u-strip has been welded on ...
and you see the two chain idler wheels.
The idler wheels were skate wheels that I turn on my drill press.
the blue thing is just a temporary spacer ...
because I didn't have another 2" x 5/16' bolt.

Here's the current status of the main tube ...
the portion to the left of the head tube will be shortened a bit
when it is tweaked and bored for the bottom bracket.
