I was able to find some time in garage yesterday afternoon.

I reamed and faced headtubes:


After I ream the headtube, I hone it with one of those flex hone things so all the rough edges are smoothed.

Here I am doing some mock up work on the chainstays: This is with about 3mm of clearance between the tire and arch when the wheel is fully forward in the slots. Not a lot of room for the stub to go on that yoke!


I brazed on the first stub using the preform that Andy sent with the yokes (foreground) but felt there wasn't quite enough filler so, I fed in a bit more manually. Then I made new preforms with a few wraps (background). I'm sure Andy has seen enough of these to know there is enough filler in there with one wrap but, I just feel a bit better having some seep out of the joint.


Also, as promised, Here's how I do the preforms:
First, I bevel the top edge of the plug:

Then after wire brushing the surface to be brazed, I wipe with alcohol and apply flux:

Clean the inside of the tube, wipe with alcohol and insert the preform

Add flux:

Use the plug to push the preform into the tube:


Add more flux:

Apply heat:


At this point, there is only completing seatstays and putting them on and slotting the seattube. Then I will build each one up and take it for a quick spin before tearing down, doing a final inspection and then sending off to paint. Hoping to have them all done by end of February.
