Making Lathe Chuck Keys

[@stemer1149]

Great video, I particularly liked how you showed the hardening and tempering in detail.

[@MaturePatriot]

Great job on the chuck keys. Very good job of step by step narrative. I like how you hardened,.....and tempered, the ends. If out of locktite, I borrow my wife's nail polish. It is very adequate for that purpose! Loved the video.

[@BuildFixCreate]

Thanks!

[@Rubbernecker]

Fantastic work as always! I was very happy to see that you came out with a new video!

[@BuildFixCreate]

Thanks!

[@dougankrum3328]

….17:50...those old hard drive magnets are pretty handy...! I was 'The Welder; in a couple machine shops, and did some hardening this way....usually worked out fine..

[@BuildFixCreate]

Haha, they sure are! Thanks for watching!

[@NeilIves]

I enjoyed that. Thank you.

[@rickpalechuk4411]

Good to see you back at it, beautiful work on the keys. Cheers

[@BuildFixCreate]

Thank you!

[@mikemcdonough3221]

Nice work Kiddo.

[@TomMakeHere]

Great work! These look very nice

[@BuildFixCreate]

Thanks for watching!

Good job I always keep the keys with the chuck when they are off the lathe. I had a poorly made key for one of my chucks and I bored the end and used a piece of HSS tool for the square end. Brazing the tool bit in works too. I have no mill to use. Thanks for the vid

[@BuildFixCreate]

Thanks! The HSS is a good idea!

[@Jeremy-iv9bc]

Hss is very brittle and a poor choice for a chuck key.

[@coalbuster]

Thanks for taking the time to share this. I need a key for a chuck on my Logan. I've been using square stock in a tap key but you've inspired me to take the time to make one. My two cents: A) I use a spot drill instead of a center drill to start drill holes in metal. B) If you do a quick oil quench when hardening, latent heat should bring the tool back up to straw where a second quench will set it.

[@stevenarango6319]

great job there...... looks awesome

[@BuildFixCreate]

Thanks!

[@fredbloggs4829]

Hi. Just a tip. if you make your cuts for the square flats from the side instead of the top, you get the flat cut and the radius in one operation.

[@bluesman7191]

He addressed your suggestion in the video.

[@MrSago]

Great Video !!!

[@kerrywil1]

Your Logan runs very quite. Why and how did you get it to run so quite? Thanks for spending time to do the video

[@RRINTHESHOP]

Nice job, they will work well for many years.

[@BuildFixCreate]

Thanks Randy!

[@xmachine7003]

Hi Randy. Nice seeing you here.

[@paulm5302]

Great Video 👍

[@BuildFixCreate]

Thank you!

[@dojmike]

Have you considered an induction coil to heat treat small conductive pieces like your chuck key. I think they are available on Amazon for about $50.

[@BuildFixCreate]

I've never thought about that but may have to look into it. Thanks!

[@mrc1539]

I have the same Logan Lathe, and crashed the gearbox while cross feeding . Took out three gears. They are available from Logan but expensive. I bought two from Logan but bought the double gear 32/16 from Bill Sauer

[@coalbuster]

Been there. Luckily, there's a lot of used Logan parts available on eBay.

[@sjansjna8895]

Sir what is the best material to make these?

[@kerrywil1]

great video. That square tube at the rear of the lathe bed, did you build? how is it held to the lathe?

[@RockingJOffroad]

I was wondering why you plunge cut the radius, now I know! Nice work. I like to make my church keys purposely a bit undersized so they like to fall out of the chuck easier when I forget to remove it from the chuck.

[@BuildFixCreate]

Thank you!

[@dalejones4186]

Can you tell me what end mill brand you used on your mill and where to get one. I’m new to metal working and am tired of poor quality China end mills. Thanks

[@krauselee877]

Just fork up the dough for a set. If you break the tip you can get em reground for cheap

[@Preso58]

Nice job. I recall learning about loss of magnetic properties at hardening temperature when I was at teachers college. I believe it is called the point of recalescence. Maybe it's the only thing I remember! 😕

[@BuildFixCreate]

Thanks Mark! Thats better than nothing! haha Chemistry major here, we didn't get into metals so I'll trust you know better than me!

[@TomMakeHere]

Not sure about that term, I've only heard it called the curie temperature

[@kenzpenz]

Pretty darn awesome indeed. Now that torch has me interested. I don't want or have the room for a full size torch system. Where did you buy the hose system, I just gotta have one of those. Thanks for sharing this great video. ...Ken Marina, CA.

[@osgeld]

ditto

[@BuildFixCreate]

Thanks Ken! I dont remember where mine came from but Home depot has it for $60 which includes the hose system, a sparker, an oxygen and a MAP cylinder.

[@kenzpenz]

@@BuildFixCreate Thank you ...Ken

[@apistosig4173]

Q: what tool post / holder are you using? I want one!

[@BuildFixCreate]

Shars quick change tool post. AXA size Its great!

[@dizzolve]

I noticed you're using the Jacob's chuck now - did you give up on the Whalstrom or was it an application choice

[@BuildFixCreate]

The Whalstrom doesn't have the grip strength that a Jacobs has. I use it when I know i have a lot of small holes and lots of bit changes. Just felt like Jacobs this day haha

[@dalejones4186]

Great video. How long does your bernzomatic torch tanks last for medium to low use? Glad your back making videos.

[@BuildFixCreate]

Lasts me at least a year because I don't use it that often. Small parts like this or heating something up to break loose a stubborn bolt. Thanks for watching!

[@jimdavis4342]

The propane will last a long time but the oxygen time is disappointingly brief. Consider investing in a SMALL acetylene setup. The store forever and will last you a LONG time by comparison.

[@dalejones4186]

Thanks guys

[@dannywilsher4165]

If you add more oxygen into your flame, it will be many times hotter. Thereby heating up the metal faster and using less gas and oxygen.

[@Larry1942Will]

I need to make longer chuck keys so they clear the head stock more. Chinese lathe & chucks seem fine (home shop) but the keys are pretty sloppy. No torch so will machine from 4130 that I have. Thanks for the video.

[@jw200]

Hello Isn't it better to dump it into oil instead of the water?

[@BuildFixCreate]

Depends what kind of steel you have. There is oil hardening and water hardening and air hardening steel. This was water hardening

[@fernanjs]

Hey, great video as usual! Let me know what size gear you need for that Logan. Mine had lots of broken gears when I bought it. I've since gone through and restored the whole lathe, and I have a few good gears left from the spare parts I bought. They're great lathes, capable of some serious cuts if you put a good grind on your tool. I put up a video a while back of mine taking a .250" depth of cut for a total removal of .500". Incidentally, I think we've also got the same milling machine! I find that these round-column mills perform much better during side milling with a roughing end mill. It's definitley worth having a few around for hogging metal.

[@BuildFixCreate]

Thanks! The gear I need is a double gear. 32 tooth and 16 tooth attached together with a 0.4375 bore - no keyway.

[@fernanjs]

@@BuildFixCreate Oh man, those are the same ones that were stripped on mine. Must be a common failure point. I looked through my spare parts bin, but unfortunately I don't have them. Another (more cost effective) option is to buy yourself a set of gear cutters and make your own gear. I've done this for my old South bend. The gears in a Logan have a 14.5 degree pressure angle.

[@erniehenshaw4161]

Looks like my Logan Lathe.

[@martingardener90]

Very nice video but those hands don't look like they belong to a metal worker - they're far too pretty!

[@BuildFixCreate]

Your right! Hands of a fake hobbyist metal worker haha. Thanks for watching!
