Grizzly tube notcher fix and first braze attempt

I managed an easy fix to the offset tube notcher problem. I’m not really happy that it needs a fix to begin with but maybe Grizzly will come through with a solution. In any case, the solution I found was to just use a file I had as a spacer to shift the tube up the millimeter or two necessary. Here’s a pic:

I also took my first attempt at brazing. I tried getting a couple scrap pieces together first.

I don’t think I did a good job… I was afraid of getting the tubes too hot. After a couple tries, I figured I might as well just go for it, so I put the seat tube and the bottom bracket together:

Before brazing (note the tube is inserted too far for illustration purposes):

And after brazing:

Again, I’m not sure I did a good job. It’s not very pretty, that’s for sure. But I tried pulling them apart as hard as I could and they didn’t budge. So there’s at least a little silver in there sticking them together. The other bonus is that I didn’t burn the house down. Next, I have to cut and miter the down tube and braze it to the head tube. Hopefully, the little experience I have now will mean a better braze there.
