lathe thread (1x10?) + flaceplate question!

[ndp_2010]

Hi, I'm looking for some advice regarding my lathe; I am a begginer at wood turning and lathes in general so I am not familiar with all the measurements and components :D

When i bought my lathe it cam with a chuck that I put on the lathe, but now when I was fiddling to try to remove it I think I may have undone part of the chuck and left it on the lathe. I have put an image of what ive done.
My question is, what is the meaning on the 1x10 on the chuck? I assume this is a thread measurement? is the 1x10 ment to describe the smaller thread on the lathe or the large thread that the chuck has become unscrewed with?

unscrewed the chuck and a large diameter thread was visible. (also the metal part left on the lathe reads 1x10)

when i screwed the chuck on for the first time i remember screwing it onto a thread like this

Also, I am having some trouble turning the bottom of bowls to finish them (I cannot grip the rim with a chuck), are there any faceplates that people recommend for gripping the rim of a bowl to finish the under side or is this not possible.

any advice is much appreciated.

1x10 is the thread on the lathe, what you have done is unscrewed the insert from the chuck, we use inserts for different lathe threads rather than manufacturing chucks with the lathe threads as it can get costly if you upgrade your lathe down the track with a different lathe thread, inserts are cheap, chucks aren't.

As for holding the bowl to finish the bottom, do a search for "Cole Jaws"

thankyou for for the reply. I definitely understand why the insert is useful.

As for the cole jaws, this looks great. I had a look and found some that might be good for my chuck however I'm not sure how the holes will align. Are most brands compatible with each other (eg, will fitting holes drilled in the jaws fit onto most chucks or must you buy the same cole jaws for the same brand chuck?)

Not usually, usually best to stick to one brand if possible.

This looks more like the thread and back of a Vicmarc Chuck

You will need the Vicmarc bowl jaws (http://www.cws.au.com/shop/item/vicmarc-bowl-jaws-vm90100).

If you are going to the Sydney Timber & Working with Wood show bring along the chuck so we can verify for you.

Do yourself a big favour and purchase or get a hold of a book on woodturning techniques something like Keith Rowley's "A Foundation Course" from the local library. It will answer a lot of these questions for you and give you a very good introduction to the basic principles of wood turning and safety. Have a squiz at Robbos videos at the start of the Woodturning Forum too - very good advice.

I had a look at your link, there are two sets of vicmarc jaws for different models (VM90/100 and VM120/140/150) is there any difference between these? Im not 100% sure what model it is or how to find out

[DJ’s Timber]

Going from your photo in the first post, I'd say yours is the VM100, some pics of the other side from a few angles with a rule or common object next to it would help.

Or you could just measure it. The body of a VM100 is 96mm and a VM120 is 125mm dia.

excellent I'll do that. thanks

[Jim Carroll]

As others have indicated the diameter is the easier indicator.

100mm for the VM90/100

125mm for the VM140/120

Then just work out what the maximum diameter you can turn then work the size from there.

[pommyphil]

Have they changed the specs Jim ?? All my VM100 are 96mm,........

[ndp_2010]

the chuck is 125mm dia. so its one of the vm 120/140. Is the csw store a good place to get these?

You'll have no problem with Jim, if you can wait, see him personally at the show the weekend after this one.
