Advice from a 38 year machinist; if your drill is long enough to go through the stock, back the drill out as many times as necessary to keep the chips clear so they wont bind and break your drill. NEVER try to make holes meet from opposite sides if you can help it. The likelihood of breaking the bit is too high; if the location of the holes is off even a little bit--a hair thickness--as you break through, you will over feed and the drill will grab just as it did here. In many cases a substantial portion of the bit will bind and break off inside the piece, and be next to impossible to drive out. That being said, I have watched dozens of these videos and find them very informative and entertaining. your skill level is very obvious. Thanks for all you reveal!

maybe metal drilling is different, but when drilling through wood we attack from both sides to keep a straight hole, for similar reasons he instructs us to keep turning the head around when we drive the chisel.

If I may suggest an alternate technique I learned from an old blacksmithing book. After drilling the two beginning holes as you did insert a low carbon steel bar in each one and then drill the center. The bars will keep your center hole from drifting to either side. I think you will appreciate the speed of forming the handle hole this way.

What would you recommend first, a tredel hammer or a fly press? I know the jist with the pros and cons between the two. Different tools, similar but different applications. Currently I make alot of smaller projects I don't mind knocking out by hand. Skulls, leaves, aliens, hooks of all too. But I really want to get more into tool making. I have what I need for now, made at the anvil. A couple hardy cutters, a hardy pillar(flat top), a spring fuller, bending jig, punch/chisel set ect. But I want to get into more with hammer/axe/handled tools. Today I got a little over my head with an axe I'm working on. First I really used the wrong material for the shape I want. (Car axel) but I got it squared off, hole punched and now I'm spreading... the long part lol. I don't mind learning and doing it that way for some of em, but for future productivity I'd like some help. Tredel or press... oh the choices lol! Hope my rant isn't too bad, and thanks again. see ya next video!

Good question. I do the rough forging and then anneal it over night. Grind on another day and heat treat, final grind on a third day and perhaps add the handle on a fourth day.

I have been a Blacksmith, making Rendezvous-type items like camp fire sets, S hooks, the occasional knife and things like that, for many years! However, I became disabled with a rare disease, about 20 years ago! It eats all the cartilage from all the joints and then erodes the ends of the bones!
