Re: Buying a mini-lathe


MERTON B BAKER
 

I have A bunch of square ones, and round by 8ths from 3'8 to 1", I think.
No hex ones. I'll have to go down in the playpen in the morning & check on
the round ones. The spindle bore on the 12 is 1-3/8" mostly HSS for
parting toolbits. they go right in under power, but the bandsaw is quicker.
I have a 7" SB shaper to do grooves with.

Ill have to make a list of the collet sizes I have...Any particular you ned?
The spindle bore on the 8x is around 7/8 I think.
What is it on the 12?
What do you use for parting? Ive used brazed carbide cut at an angle as well
as T type cutoff tools. Both work good.
Ive been considering using the the .040 cutoff for slotting, its Cobalt. I
would have to figure out a holder for it. It wll go on a
gang tool cnc lathe which has 3/4 in tool holders. Space is limited, as I
have 8 tools on carriage now. It is fed by a bar feeder
and automatic collet closer.
So I am planning to mount the grooving tool on the end of a 4140 rod. There
could be a cross piece of rectangular bar on the end of the rod.
Perhaps the cross piece could be brazed to the rod, and a simple clamping
arrangement would be bolts and special washers to hold the T type
cutoff-grooving tool at a right angle to
the axis of the rod.

Got the 12X from an outfit in Nevada a long time ago. It's Jet brand from
Taiwan. I remember thinking at the time I uncrated it, that the local
machine tool factory (Chas. G. Allen) wouldn't have let it out of the shop
looking so crude, but it has performed extremely well for me for nearly 30
years. I'm using it for my present project, making endmill holders for
Unimats.
I made a 5C collet closer for it, but have yet to need it for anything.
I'd make these Unimat endmill holders from 3' lengths of bar stock on it,
but the 4x6 bandsaw cuts 'em off quicker than I could part 'em off , even
under power on the lathe. The collet closer I made for the 7x, takes 3C
collets, right in scale. I'm interested in more 5C collets; what would
you
like to have that I might have lying around useless? What size spindle
bore
does the 8x have? One of the reasons I sold the 9x, was the 3/4" bore,
same
as the 7xs. That is huge for such a small lathe as the 7xs. I sold the
Atlas 618 I rebuilt for the same reason; except for the bed length, the 7x
was bigger all around.

Thanks for reply. Where is the 12x from, and do you like it?
I too have a 5C collet chuck. (lathemaster). I never use it, but I have
hundreds of extra 5C collets, which I plan to sell on ebay.
How close is your tir on a workpiece and what is your procedure for
truing?
I have a 7x10 I bought on ebay for 200$. I replaced the motor controller
and
need to fix the rack. If I put the %C on the *, the 7x could take up the
slack.

Good question. Got the 7x10 out of curiosity, and felt limited by the
10"
dimension, especially when drilling. saw the Homier on sale for 300, and
bought one. 7x12, it said. When it arrived and got unpacked, I
discovered
that the 12 was from the chuck face, and not between centers. Even
salesmen
make errors. Not at all saddened by this, and enjoying the extra room, I
found the Grizzly "7x12" on sale for 325, I think it was, and still
curious, I called Grizzly, and was informed that the lathe was out of
stock,
& if I agreed to wait, on backorder, they would deduct $50, and ship it
free. I agreed. Now, with three lathes, it didn't make sense to swap
chucks any time I needed the 4 jaw, so that went on the Griz, and the
collet
att. I made went permanently on the 7x10. The last one was an
extravagance.
I was at a Cummins truck sale, and the Cummins version, which comes with
ALL
the extra stuff, lunette, follower rest, face plate, TS chuck, etc. and
bought it. This was before Cummins got embroiled with the diesel people,
and changed to "Toolsnow". the Cummins Lathe has been sitting in its box
to
remind me not to do things like that. Good thing my shop is fairly
large.
It's handy having the 4 jaw ready to go, but the collets don't get much
use
now, although when I was making the closer, they seemed imperative. The
Homier and the Cummins are RBs and the other two are SIEGs. At the
moment,
most of my work is on the 12x36, and a couple of Unimats. The 7xs get
used
a lot when I have a job on the 12x that I don't want to take out of the
chuck. I'm retired, and the shop is now my playpen, & provides a little
extra income as well. I can make most anything someone is willing to pay
for.

Yes, it is. Can't pan it, never used one, or even seen one.
When I bought my first 7x lathe, I already had the 12x36, and I had all
4 of the 7xs I now own, before the 8x14 appeared on the market. I had a
9x20, though, & sold it. It was bigger than the 7x10, all right, and
bigger
than the 7x12 (14)s as well, and had 1/3 of a QC gearbox, too, as well
as
a
nice wide T-slotted top on the cross slide. It weighed at least 300#.
I
paid 300, (used) and after I'd made a few improvements, (Camlock TS, QC
toolpost, Lights) sold it for 800. When I sold it, it was much more
useful
(better) than a new one. At the moment I have more lathes than I need,
and
have a Uni 3 for sale.

I own both a 8x and a 7x. The 7x is like a toy compared to the 8. The 8
has
massive ways, a big solid TS, and works right out of the box.
The 8x has the feel of a big lathe. I dont cut LH threads, need a feed
towards the tailstock, or variable speed. I just leave it at 800 rpm for
everything from aluminum to ss. If I really need a different speed, I
change
the belt in one minute.
At 560, its a buy.

Maybe. If you need an extra inch of swing. If you don't mind changing

don't
know anything about the 8x14, except what I read on this list; don't
even
think I've seen one in the catalogs. In my experience though, the
7x12,
(really a 7x14) is the best small lathe, which is a real engine lathe,
for
anywhere near the price. I own 3 of 'em as well as a 7x10. They lack
only
the 40 thread LS gearbox, separate power feed shaft, & cross slide
power
feed, which I enjoy having on my 12x36, with the 2 HP 240 v. motor. I
do
have to change belts for the 6 fast spindle speeds, and unscrew the
bull
pin
& engage the back gears for the 6 slow ones. It does have plenty of
torque
at 30 rpm, though. I like the 1-3/8" hole thru the spindle, too. FWIW,
I
bought a HF 7x10 out of curiosity about 20 years ago, and have been an
enthusiastic fan of the 7xs ever since. Especially, for someone with
limited space, (I have 1500 sf), & a limited budget, (I'm a retired
schoolteacher). I wish these were available in 1958 when I bought my
Unimat
DB200.

MUCH MUCH more!!!

but keep in mind.. no variable speed control (all belt speeds)..

and I dont think there is a lead screw reverse lever.. (only if you
run
chuck in opposite direction)

(without tumbler gear or whatever)

Go to fignoggle.com to see comparrison pics of the 7x vs the 8x.. The
7x
is like a shoe bow!

The HF 8x14 now on sale for 699. With 20% coupon that reduces to 560.
The 8x14 is much more machine than the 7x.
