Thank you for the quick reply! I didn't realize how much torque you had to put on it I guess. It looked so easy!

Hey Zane, there is very little material at the outer end so it simply distorts under the torque. The only practical way to get the insert firmly placed is to slot it in the region with the most material, and then screw in

Zane Gifford

I still want to know why you went thru the trouble of making a right angle screwdriver when you could have cut a slot into the threaded side and just used a regular driver. Any comment?

Cheers PJ! Just putting the finishing touches on that one now :)

Nice Chris! Also loved the shot through the back end...Creative and way fun...What?...whats he doing? Too cool to rule! Thanks always, looking forward to Part Deux. ~PJ

Nothing like a close-up to reveal all sins! Cheers Rob :)

I think if i was to make a set of nut drivers, it would give me a good excuse to buy a rotary broach. <a href="http://www.slatertools.com/rotary-broaches/internal-rotary-broaches" rel="nofollow noopener" target="_blank">http://www.slatertools.com/rotary-broaches/internal-rotary-broaches</a>#.VhjrC_mqpBc. I've been hanging my nose over one of those for some time... :)

Righto, that makes sense! Thanks Chris! Keep up the awesome work, love the videos!

Cheers Rupert :)

Great work Chris. It was interesting to be able to see the deflection you get when grooving the brass handle. I know you need to be careful of how much a narrow diameter part overhangs, but it is great to see how much it affects the job. (Nothing critical this time!)

Great video as always Chris!

off topic but I would love to see how you would go about creating a tool like these special nut drivers - <a href="http://www.micromark.com/4-piece-nutdriver-set,7450.html" rel="nofollow noopener" target="_blank">http://www.micromark.com/4-piece-nutdriver-set,7450.html</a> My first guess is you would drill the tip out then finish the shaping for each size with a broach? Or maybe they are simply machined and cleaned up to give sharp interior edges. Thanks for the awesome videos!!!

Hey Paul, great to hear from you! The reason for that is standard twist drills have a tendency to wander off course. To reduce that tendency, a hole is started with a shorter, stiffer spotting drill (or some folks prefer to use a center drill). Being a lot more rigid, these drill bits cut the start of the hole exactly where you want it to be, making a small cone shape. Any drill bit following this first cut, can't help but follow that position (at least to begin with), so the rest of the hole creation starts in the correct position. There are limits of course, and although it starts in the correct position, keeping it there is another story! Thanks for asking :).

Paul Warren

I'm a complete newbie with machining, but why do you always drill things twice? First a shallow one, then change bits for the proper cut.

I loved the shot where you filmed from inside the headstock of the lathe while inserting the stock. It's little touches like that which make your videos so brilliant.

Clickspring

Hey John, this one was a bit of a scrap box creation, and I had the the size I needed in a mild steel. Its only ever going to be interacting with other bits of mild steel, and even then maybe only a few dozen times over its life.

John Creasey

I'm surprised you didn't use drill rod on the tips.

Clickspring

Awesome, so pleased you're enjoying the vids :) I chose Loctite mainly for simplicity; its super strong, and just so easy to break the bond with a bit of heat. I would probably use a more mechanical approach if the tip change was likely to be more frequent, but for this tool the tips will only be swapped out once they get messed up, which really should only be once in a blue moon.

Magik Eh

:D I cannot complain about that any! I love watching you work. Also, did you think of other ways to make the tips interchangeable? Why did you choose a locktight bond (I know you do love the stuff so) rather than a tight key'd design or something of that sort?

Clickspring

They're a great little tool aren't they! I must admit I was going to just pick one up off Ebay to save some time, but the thought of another video was too tempting :)

Clickspring

Hey Brian, yes that's brass.

Magik Eh

I've had one of these screwdrivers in my tool kit since the beginning of me. Always just the perfect tool to have when needed, mine however is just a solid piece of steel. Nothing too fancy for me ;)
