I'm about to start manufacture of a part which requires a 10mm dia steel tube brazed into a 10mm thick steel plate. The rod is hardened steel and needs to be at right angles to the surface of the other part. Problem is that I need to allow about 4 thou clearance to allow the braze to flow (2 thou each side) but I need the steel tube to be at right angles to the steel plate, and 4 thou is quite a lot of potential (highly technical term follows) wobble . The tube is 33mm long, so only 23mm will protrude above the plate.
The best idea I can come up with is to bore a piece of 25mm steel rod 10mm and hollow out the part where the join will occur, sort of like a three legged stool with very short legs and a very thick seat.
I have also considered centre punching the ends of the hole to hold the tube correctly before brazing, but I'm not sure how successful or accurate this would be.
I have come across this issue before and have always resorted to bodging it, on one occasion even reheating the joint to reset the position.
Any tips or advice on how HMEM experts :bow: resolve this problem most welcome.
Many thanks for your time
