Above is my jig to keep the rear triangle in place while I tack it and cut and prep the seat stays.

This basic jig made it easy to lay the frame on the drawing and pull the alignment measurements up off the drawing.

getting ready to cut the seat stays


almost done with the filing.

finish filed


Here is the seat stay fitted and almost ready to braze.


Both Seat stays ready for brazing, but next is the seat stay ends at the top tube


Both Seat stays cut to length

Fitting the cap to the seat stay.

So while I was brazing the cap to the seat stay I tacked the chain stays in place... not the greatest tack but it worked.


After brazing the cap and a little triming on the grinder.

Just about to file it down.

Fitted up after filing and sanding... they aren't perfectly square but I am happy with it.



You can see in this picture the left cap is just a little bit bigger than the right... that is haunting me now.

Now I am brazing up the rear triangle after a few checks to the drawing for accuracy and to make sure I have the right BB drop.


Well after all the overly simple jigs and what not the rear triangle came out pretty straight and square, I had one slight mistake. It seems that the rear wheel is just slightly out of square so the by about a mm at the rim. So the brake bridge is going to be slightly off center but I will see what i can do.
I will have more pictures of the new fork and brake bridge tomorrow.

Thanks, I am so close to finishing I am getting a little nervous.
yeah it is pretty warm here in socal, it has been blowin 30 to 50 mph Santa Ana winds for the last 3 days which makes it about 80 degrees day and night... the only bad thing is the wind blowin into my garage and moving the flame on the torch :)
