Longworth chuck and other lathe tools

I recently got a lathe for my wife (honest Honey) to encourage her out to the shop more. Neither one of us has done any woodturning before so we’re having fun learning. In anticipation of turning bowls I made a Longworth chuck. I also made a thin parting tool out of scrap maple and some large bandsaw blade. The other tools are a burning wire, knockout bar, hand chuck, and lock pin. I could see how this turning thing could be addictive.

Greetings from your North Idaho neighbor. Nice job on the Longworth chuck and the other lathe accessories. Having a nice lathe is one thing but having practical accessories to use on it really enhances it’s capability and your FUN quotient. Making those accessories adds to your satisfaction level also. Glad to have a fellow LJ in the neighborhood :).

Ray,

I just brought home my Jet-1236 on Saturday. So far, I’ve used it every evening.
How do you use the knock out bar? When I remove the drive spur, I screw in the locking pin, and then tap out the drive spur with a wood block and mallet. I’ve been watching how to videos but removing the spur is usually skipped or they are using a lathe that allows the spur to be tapped out from inside.

What is the hand chuck for?

Lee – it’s hard to beat the NW in the spring and we’re having some great weather finally!

Rocko – I hope yours is new. I had to put bearings in ours but now that’s done all is well. The knock out bar goes through the head stock and allows you to pop the drive spur out with a little tap of the bar. Watch Eddie Castelin’s youtube where he uses and builds one (among his other informative videos). Much easier and better for your lathe.

The hand chuck is used for drilling smaller holes on the lathe by hand (again a tip from Eddie). Just create a center divot with your preferred lathe tool, and push the bit in. Much quicker than setting up the chuck. I’d say you’re probably limited to 1/4” holes or so.

Ray, The hand wheel on my headstock is solid….no hole to slide the bar through. That’s why I was a bit confused.

Rocko – we don’t have a hand wheel so that makes sense. I think that thread is 1/2” x 13 left hand which doesn’t leave enough to drill a center hole either (I’ve been thinking about making a handwheel). You might try taking the handwheel off and if it’s just hand tightened you could slip it off when needed. Just seems like getting the drive spur out otherwise would be difficult. You may also want to vacuum chuck or run collets which would need it off.

Ray,

That’s the answer!! I’ll confirm this evening. I’m glad I found your post.
The hand wheel has a hole in the shaft (perpendicular to the drive). I found the knockout bar fits in this hole perfectly but didn’t know why. I think I’m supposed to use the knock out bar to loosen the hand wheel, remove it, and then use the bar to remove the spur.

I doubt I’ve done any damage to my bearings by taping the spur from the business end because I’ve only done this a couple times using a rubber mallet and after the fist time I locked the spindle. I did get my lathe used but the guy I purchased from only used it half a dozen times.

Thanks for your help.

Great work on the chuck and the accessories. All good stuff a turner needs.

Great project but I really love your biline. Hard work is opportunity in my opinion. I’ll stop my rant there! Keep up the good work.
