View Full Version : 2.5 inch chuck?

I have a tiny Adept lathe, barely a handful but it qualifies as a lathe nonetheless:-

I have just bored out the headstock and made an oversize spindle, 10mm up from 3/8th. Just a plain shaft so far.

I would like something that 'looks the part' more than that little drill chuck, a 2.5" chuck would be nice!:D

3" chucks are available if I want to spend that much money on what is really a novelty or I could make a back plate and/or a centre.

Any ideas of how hobbyists used to make little chucks for a lathe like this?

Thanks.

Many of the pictures I found show it with either a faceplate of interesting design, or a dog chuck. I would think you could produce either fairly easily.

It's not often I see a gap bed lathe in that size :)

The Adept 3 jaw chuck would have to be within my capabilities but it sure does look ugly! Their nice little 4 jaw would be a great find!

Ah well, time to make a face plate I think..:rolleyes:

Would this happen to be small enough for you ?

I believe the chuck on my uni is smaller than 3" but I can't imagine finding one of those very cheap.

There should be 2 1/2 inch chucks still around somewere.

My little "Wade CVA" has a 2 1/2 chuck, a 3 jaw, and a friend has an Atlas 618 that came with a 2 1/2 inch chuck besides the 4inch that is presently on it.

how did you go about boring out the spindle ..i have a super adept ..mint condition except someone used it without realising they are suposed to oil it....and they fitted a 6000 rpm motor...so the bearing surfaces probably lasted a few mins.

it has a tiny 4 jaw chuck with it..no countershft

all the best.markj

Unless you will settle for a 3" chuck you might as well do something else. I see them all the time for $40 to $65. Most are 3/4 -16 mount. TAIG has a 3 jaw for $65. I have a TAIG lathe and the chuck is quality.

Yes, thanks, that looks small enough. I wonder if they would ship to New Zealand?

Thanks. There is one of those machines for sale here right now but they want nearly $400 and it is very dirty and rusty. It is a slightly earlier version than yours, there are no accessories but it does have the chuck.

Of course if I bought that I would have to 'restore' that lathe too and I would still be short one chuck!:)

Yours looks very nice.

Dang! There was one of those Wade lathes sold last week, looked to be in very nice condition too! I think it went for a bit over $200. But again, if I bought that lathe I would not have been able to rat bits off it and I would still be one chuck short!

The Super Adept seems to have been a leap above the standard Adept.

I bored the head with a D bit, I used a length of 3/8 in my 'big' lathe to align everything with the Adept lathe clamped to the tool post.

Thanks, if I have to resort to buying modern that is another candidate.

Buying modern is possible, maybe I can find a local NZ source. Unfortunately I expect postage would double the price if I bought from the US.:(

Meanwhile, I will make a face plate and a dead centre which will at least look the part.

Thanks.

x2 on the Sherline chuck. We used them on a couple of special machines that I built several years ago. Good quality!

Yours looks very nice.


It did a couple months ago when I went threw and cleaned it all up. apparently the "lubricating oil" that I sprayed it down with didn't stop rust like it said it would.

I have one of these Bison chucks for the Taig lathe.

Pricey but very accurate and tons of holding power. I got mine before Bison's prices skyrocketed.

I would really like that 1.9" chuck Geoff, but nearly $300 plus postage to NZ, oh dear, I think that is a little out of scope for this project!:D

Hey Bodger, want another Adept, this one is the top of the range though, it's a SUPER ADEPT. :p

Nah, no chuck on that one either!!!:)

Another possibility - aka good price, are the Taig 3 and 4 jaw chucks. They are 3/4 -16 direct mount but you could fit an insert.

A2Z http://www.a2zcorp.us/store/category.asp?Cguid={45F56268-B481-44D6-9E98-688DDDD785D1}&Category=Taig:Accessory Lathe

sells them as do Taig themselves. Both ship via USPS.

The scroll chucks don't have a huge amount of holding power but should be fine on your lathe.

There are 2.5" diameter 3 jaw and 4 jaw chucks listed on the Sherline (Australia) website with choice of 3/4x16, 1/2x20, 12x1 and14x1 mounting threads, and a self centering 2.5" 4 jaw with the 3/4x16 thread only.

http://www.sherline.com.au/Sherline%20Chuck%20Information.htm

No prices though. It might be worth checking the Australian prices - could possibly be cheaper to buy one from here when postage is taken into account if you decide to buy a new chuck.

Umm, I don't see whether Artful is thinking 3 jaw only or 4 jaws might be acceptable. A 4 jaw along the lines of the Taig 4 jaw should be within the HSMs ability range if a lathe and mill or shaper are available.

Hunk of material for the body, 4 pieces threaded rod (3/8"OD x 2"?), 4 pieces jaw material (1/2" x 3/4" x 1.5"?)

For specialized tooling, all one might need would be taps to match the threaded rod and a 1/2" or 3/8" Woodruff cutter. The thread to match the spindle could be single pointed or cut with a tap.

What I am trying to do Cam is to make this little lathe look 'complete' so that I can put it on the shelf and look at it, but I would also like it to be really usable, (even if I never use it!:))

A home made chuck is what I had in mind in the opening post, yes I have a 'real' lathe, a mill and a (tiny) shaper but I am unsure if the required skills are available to make a model of a conventional chuck. :D
