Inner threading turning tool out of HSS...Need for astronomy project
propane gets hot enough for silver solder, that will be strong enough.
This is a cool idea. One suggestion I heard was to file a square hole
in a rod, grind an HSS tool, insert it and hold it with a set screw.
Your way sounds easier only I don't have any welding equipment. I do
have a propane torch but I don't think that gets hot enough to braze.
What would you suggest I purchase to do a small job like this
repeatably?
