Used to make jugs and drill guides like that all the time. Used mild steel for the body and drilled the holes large enough to take hardened bushing. Very seldom made the bushings in house it was easier to order from the tool supply. One jig you would use a spotting/centering drill with its own bush, switch it out for the next drill and bush, tapping size, tapping guide, clearance drill what ever you needed. All that changed when the CNC centers came in.

Pretty cool idea. Never even though about using a jig to drill my pin holes, thanks Walter!

I guess if every handle you make is exactly the same, but pretty soon you'll have 100's of drilling jigs around. I drill the tang (this way your holes are centred in the blade and not too close to the finger choil ;) ) then use the tang as my jig for the handle material. It's not nearly as complicated as you make it sound! Even if your drill press is slightly out of square the difference is minimal enough on knife scales that pins will still tap in.

Okay - I would have wagered at least two dollars that "Perpendicularity" wouldn't have been a word. I stand corrected.

i maybe wrong but perpendicularity is a a word

Yes in college machine shop we learned geometric tolerancing and dimensioning. Cylindricity ,parallelism, concentricity, runout,circularity, true position, and the dreaded total indicator runout (TIR). Then you get some welding symbols, surface finish and it looks Greek but after a while it just clicks. All those words are real but the stupid spell check says they are not. As engineer or scientist the spell checks are crap. I see it all the time in chemistry, glass blowing,machining, mechanical engineering.

Another useful video..thanks Sir Sorrells!

Cool jig/tool. Could be handy as a sizing guide in woodwork as well for joinery of all sorts, just make the tool/jig to suit your needs. I can see a dovetail version for making infill planes with tool steel bottoms and brass sides. Thanks for the tip. Question, have you ever done angled pins on purpose? For a certain astetic or shear resistance or something?

Too late now your tool is hardened but It is often helpful to have a means of locating your holes parallel to an edge. Threaded holes or roll pins work and are removable when not needed.

Chris Turley kind of like a fence? Great idea. You could drill and tap a couple of holes on the side and put a sliding (up and down, or diagonal) fence, made out of either hardened tool steel or mild steel. (Like a rabbiting plane fence idea).

Thomas Russell Yes, most but not all material will have an edge to reference from. A fence gives more secure accurate drilling. Most jigs like I made or used had three pins. Two for the edge and one for an end stop.

Love the the thinking

is there a different tempering process for a tool like this compared to a knife? it would seem like it, since hardness is more important, and toughness isn't as much of a necessity (just don't want it to shatter if it gets dropped). your tempering process was different compared to a knife, and seems to go along with what i was thinking there.

They have what they call transfer punches that come in a set that starts 3/32and goes to17/32 so it's like this first line of punches is 3/32-7/64-1/8-9/64-5/32-11/64-3/16-13/64-7/32-15/641/4-17/64 and up so on punch on time save you some time and percussion holes and under a $100.00 well worth it if you plan on doing a lot of drilling of any sorts !

We need to know what song that is at the beginning of the video WALTER

Great idea! Thanks walter! Whats the carbon content in 01 if you dont mind me asking?

Maybe I'm missing something but why not just use a transfer punch? I've been making knives for over 10 years and have never had a need for anything like that.

First?

Lol normies be like, square? Those are round mother@$$_&#

A total waste of time to make your fixture to drill handle holes. So much simpler and faster with other methods. I had no idea this video was so old and out dated. I should have never watched it. My bad!
