Wood Lathe Question

[mower]

I have recently aquired a wood lathe. Up to this point I have never owned one and only had limited exposure to the more crafty side of woodworking. I am trying to buy a chuck for this lathe which has a spindle of 1", 8tpi. I'm a bit confused to find lathe chuck mounts advertised as "D1-3" etc. I'm sure one of you more seasoned woodworkers can enlighten me on how to buy the correct chuck.

The various Morse and Jacobs taper interchangeability make my head hurt.

I'd simply call these guys and ask the chuck experts:

"D1-3" etcThat sounds like a Metal working lathe chuck size not a Wood working lathe chuck size.

Follow Bob's recommendation.

mower, if your looking at D1-3 your looking in the wrong place. Check out Highland Hardware, WoodCraft, or any of the major woodworking suppliers. Highland has a scroll chuck with 1"x8
Your chuck won't have a taper but rather threaded.
Your tailstock will have a taper probably a morse taper 1 or 2. You'll need to know that when buying a center etc.
Good Luck

I suspect the odd terminology you are seeing may have to do with Morse tapers whereas you want threaded attachments. I looked on the Woodcraft website and they have faceplates labeled as 1" 8 tpi and I know I've seen them elsewhere too.

The part number on the Woodcraft website is: 15M76

If by chuck you mean a Jacobs chuck (like on a drill) then you may have a little bit of a hard time finding one that has a threaded attachment as opposed to a Morse taper. Your tailstock will likely accept a Morse taper.

What exactly are you looking for by way of a "chuck"?

Thanks guys. I'm actually looking for something like what I have used on a freinds lathe several times. It was a three jaw chuck that was self centering. I think it was originally meant for metal lathes, but worked perfect for what I want to do. It screwed onto the headstock just like a faceplate would be used. My friend's lathe has a 1.5" X 8tpi, but mine is 1" X 8tpi. I have found really fancy chucks for serious wood turners that would fit my lathe but they are very pricy. I have seen several used chucks for metal work like my friend's at very reasonable prices but the terminalogy baffles me.

The 1" Dia x 8 threads/inch is a common spindle on to which you mount a faceplate and or a chuck adapter plate to which the 3 jaw or 4 jaw chuck would be mounted. This adapter plate will have a outside diameter that fits very snug into a counterbore or inside diameter in the mounting surface of the chucks back.

I would advise a small chuck as wood turning lathes often go way to fast for safe use of a 3 jaw or 4 jaw normal chuck intended for metal turning lathes.

Mower,

Following up on what Gary said...

I would be careful about using a metal lathe chuck on a wood lathe. Top speed on a metal lathe is likely to be 1800 RPM whereas wood lathes can spin at up to 3200 RPM or higher. So, make sure the chuck you get is rated to turn at the speed your lathe turns at.

Also, since some of those metal lathe chucks look pretty hefty to me, I would make sure that your wood lathe is up to spinning around that much mass.

D1-3 is a camlock type chuck mount that is used n metal turning lathes. Here is a picture of the spindle nose for a D1 type chuck:

You can't make a D1 chuck work on a threaded spindle. If you want to try and use a metal lathe chuck on your threaded spindle, you will have two different options.

1) Some makers offer metal lathe chucks with a threaded back. Unfortunately, you will probably have a very hard time finding a threaded back metal lathe chuck for a 1"x8 spindle. The most common sizes are 1 1/2"x8 and 2 1/4"x8.

2) You can buy what is called a "plain back" chuck and an unmachined adapter plate. You will then need to have the adapter plate machined to fit the back of the chuck and then bore and thread it to fit your spindle.

The advice to make sure the chuck is capable of safe operation at the spindle speeds your lathe has is very good advice.

You know, you can make lots of chips on your wood lathe with a face plate for bowls and such. You just fasten the stock to the face plate with screws. Or you can fasten a sacrificial piece to the face plate with screws, turn the face off flat, then glue your stock to the sacrificial piece with kraft paper between stock and the base so you can get them apart later. For spindle turning use a spur center in the headstock and a live or dead center in the tailstock.

This is the Oneway Stronghold chuck for wood turning. It is probably the best on the market for the purpose. I have one with several jaw sets and I use it very often. It ships with a 1x8 adaptor, but can be ordered to fit any lathe configuration.

Oneway makes several units for varying tastes. I googled the above image but any reputable turning supply outfit will have one.

PS 4 jaws better than 3 for woodworking.
