Metal Lathe Collets

[PTownSubbie]

Alright, I came across a steal of a 7"x10" Harbor Freight metal lathe. I am sure some people around here own them but I would like to figure out the appropriate collet chuck holder and set that fits this lathe.

Here is the manual: http://manuals.harborfreight.com/manuals/93000-93999/93212.pdf

Does it have to be screwed in from the backside? Links would be great!!

Thanks and Happy Thanksgiving!!

Yes it does , that's the design . Little machine shop has this one http://www.littlemachineshop.com/products/product_view.php?ProductID=2532&category=-421559299 , it's a bit pricey but allows the stock to go all the way through the collets . You could go this way http://www.littlemachineshop.com/products/product_view.php?ProductID=2231&category=-421559299 which fits in the MT3 spindle on that lathe but the working depth is only a little over 1" , but the price is much more affordable . They both accept ER32 standard collets so you can use the same collets on either your wood lathe (with the proper holder like the PSI or Beall) or the metal lathe .

Butch: I think that you mean er32 not 23, yes?

That is excellent! I have a full metric set of the ER32 collets and I was hoping to not have to get another set. I will have to see how money is on which one I will get.

Thanks for the info!

Save your money for the $200 version, well worth the extra $130. I have both, and use both. But I could live without the $70 MT version.

Really??.....I was reading a forum yesterday where machinists were talking shop and they all seemed to be of the opinion that a MT mounted chuck would have less runout --i.e., be slightly more accurate-- than a spindle mounted chuck....??

I never had a run out problem with either one of them.

The inside depth of the MT chuck is too short for most of my work, it is not hollow and requires a draw bar. With the other, I can run the material inside of the headstock. I actually worked a 3 foot piece of 1/2 mild steel, that I needed one end drilled and tapped. It is also shorter than the 3 jaw chuck, which gives me extra bed length to work with.

I would think that the opposite would be true . The MT would have more run out due to the construction of the MT and even any little bit of dirt or something would throw off the MT from sitting perfectly . I also prefer the ability to run the stock through the head stock which you can't do with the MT chuck .

Well yeah, truthfully, I did too.

But I figured guys who are machinists would know more about it than I do.

Absolutely......I also like the spindle mounted option better for that reason.
