Help,
Today I welded the headtube of the bike an disaster: I’ve now an Internal weld bead to remove from the headtube in order to accommodate the fork tube. I’ve tried to remove the bead by hand with: files for metals, wedge + hammer, metal saw but I didn’t succeed. Next option before cutting the tube and starting again is to buy hand drill flexible extension (to enter in the tube) and a 28mm flap wheel or metal hole saw for steel… but I’m not convinced. I’ve also thought to use Pillar Drill but I’ve not been able to image a way to block the bike frame on the table to let the bits enter the tube.
This are the dimensions: headtube inner diameter 28mm, the weld bead is approximately in the middle of 300mm headtube.
I’m posting here, maybe someone has solved this in the past or have any advice?
Thank you
