So, today I had a chance to prepare the frame ready for powder coating. The lock stop is now fixed, I used the old bent one, straightened it and added some more material by welding to get the correct shape. Then covered all the sensitive places and sandblasted the frame.
After the sandblasting I noticed that the frame was cracked! The left bottom tube was cracked almost all the way around just next to the seam. Patched that up and then the final blast.
Freshly sandblasted XBR frame - A new start for this bike:
My best friend TJV, who's in my opinion the best mechanic around, and has helped me a LOT with various projects, including this one.
A nice little detail, got the model plate off pretty intact and it will be a nice touch on the finished bike.
