No worries on being embarrassed. I burned a few endmills learning. Keep up the good work!Dave
Drillin on a tube is sometimes difficult, do yourself a favor and buy couple good quality short spot drills, they don't wander on the surface so easily. You are not the first to cut a hole off center and it's just telling that you are making something. Will be interesting to see this one finished and shooting! I hope I have some time to make some parts in the near future. Marko
Fwiw, people think it is easy to ‘take the temper (hardness actually) out of hss’. Years of sharpening toolbits has proven that false. If you don’t believe me, give it a shot. Try to cut that drill bit with a file after you turn it blue. Dave
The old handbooks all extol the virtues of HSS as being that it will retain most of it's hardness even after being heated to a red heat for a short time... A lot more extreme than just drawing it to a blue color; I've sharpened up badly abused drills that had the ends melted-only ground them far enough back to get good flutes; and they cut just fine (and no; I didn't melt them )...Only thing to watch when cutting drills down, is that (on most of the ones I've dealt with, anyhow) the web gets thicker further up the drill; which will make for a useless bit at a certain point (IME this only really shows when you're down to the last 1" or so of flutes)...Jesse
Be sure to vent the tube in front of the hammer or you will loose alot of hammer energy for moving air in front of the hammer. Marko
Interesting. I am still learning heat treating. I've learned that my toaster oven heats stuff up too quickly. Things that should be straw quickly went to blue or grey before I could pull it out. I am going to try to heat treat the hammer at some point using casenite. Any advice on that would be great. I only have a map gas torch.
is that 10.7 ounce hammer ?? sweet
