Hi,
I am debating on which lathe to buy the 7x12 or 9x20 and was
wondering what the largest cap. that a 4 jaw chuck will hold in
either of these 2 lathes? I think that the 7x will be large enough
though I will have to purchase the 4 jaw for it. Also what is the
largest recommended size chuck for the 7x?
Is the speedway as good a lathe as say the Grizzly or HF?
Thanks for any info, cfshouse

CFSHOUSE:
I have a 7x12 (old version Homier). The current Homier and Grizzly are
pretty much the same unit. Several of us with this lathe have recently
bought a 5" 3 jaw chuck from J&L Industrial, on sale for $64.
Part no. is PCC-05000



The chuck jaws still seem to clear the ways of the lathe at max extension.
The specs say the external jaws can grip an OD of 110 mm or about 4.33
inches.
There is a 4-jaw 5" chuck made by Bison that a minilathe owner has and is
happy with. But, it's a bit more expensive, at approx. $150. If you need a
4 jaw though, this might be a good way to go if you want max capacity with
the 7x12.

One word of caution. You will have to find or make an adapter plate to
mount a 5" chuck on the mini lathe. There are several how-to web pages to
guide you through this. Makes a good project!
Regards,
Flint

Hi, Flint. I bought the 5" chuck, but have not had
time yet to make the backing plate. For those who are
interested, the following link has lots of info on
chuck options for the minilathe, and a link to the
page on how to make a back plate for chucks larger
than 3" diameter:

Frank, I haven't made by backing plate yet either, but I have some materials
for it. I have a nice 1" thick piece of 5" diameter 12L14 that I am going
to use.

I read about Rick Kruger's adjustable chuck plate and was kind of intrigued
by that idea. Perhaps that's a good fallback design if one tries to make a
non-adjustable chuck and ends up with too much runout? What do you think?
Flint

Rick's got a great idea. The same thought occurred to
me when I was last making a backing plate. Maybe I'll
try that on this next one.

Here's a link for those who may wonder what were
talking about:
