I’ve been making my own carbide turning tool and just finished the handle. I need ideas on how to drill a 5/8” hole in the end fairly straight and true to hold the tool rod. I couldn’t do it on the lathe due to problems removing my live center from the tailstock, and lack of a steady rest. I’m thinking about building a holding jig to use on the drill press to get a pilot hole started, then using that hole as a guide for free-hand drilling. Here are some pictures of it:

Just thought of something… I might be able to chuck the brass ferrule into the lathe headstock (supporting the back of the tool with the tailstock live center), and drill through the headstock. I would need to find a long bit (and maybe some kind of adapter collet for the right diameter), but I think it would be possible… I’ve never done any lathe drilling before. Any thoughts?

Maybe you could make a jam chuck to do it. Put a piece of wood in a chuck or faceplate, drill or cut a hole the same size as the ferrule, then drill through the headstock as you had planned.

You could use a hand drill. I would make center line marks on the side and top for reference. Start with a small bit and work your way up to 5/8.Line up the bit with the pencil marks.

1 more thought. You will need a lathe with reverse or use a left handed bit to drill through the headstock.

Dang, you’re right. I might be able to stop the lathe and drive with a hand drill.

Hindsight is 20/20, Drilling the hole first would have been my suggestion, before turning on the lathe..

Another option is to take a thick piece of scrap. Use a forstner bit to drill a hole the same diameter as your ferrule, but not all the way through, only about 1/2” deep or so. Then use a brad bit the same size as your desired hole, drill the rest of the way through the scrap (all on the drill press). This will then become a guide block for drilling a centered, perpendicular hole. Stick the handle in your vise, put the guide block on, drill with a hand drill.

Another option, drill it and hope for the best. If you get it straight beat your chest and proclaim victory. If it winds up you not that good, or its just a bad day, drill it a little larger, center it and fill it with epoxy.

I would use the drill press to drill the square blank first, then turn it .

I have used the method Ripthorn has offered with success.

Either drill it in the drill press working up from small drills to the required size or make a pilot hole and hold the drill in the headstock and hand feed the handle onto it if possible using the tailstock as a way of driving it home but this is not neccessary.RichaRD raffan does it this way all the time with great success incidently I make alot of my own tools too inc tc tipped.Have fun young knight.

I think better way is make a hole to the wooden prism and turn it on the lathe.

Ripthorn, that’s a great idea for the drill guide. I might give that a try if my lathe drilling setup fails.

waho6o9, I also like your modified hand screw… maybe if I got two of those clamped vertically to keep it steady on the drill press table.

Yes, I should have found a way to do this while originally turning the handle, or while gluing up the blank, but I’m rather dumb sometimes. If I screw this up, I can make another I suppose. Thanks for all the great ideas.
