Hello everyone,

I'm a new member to the group. I would like to buy a mini metal
lathe, can anyone give me websites where i can find them.

Any sugestions on what kind and size to buy (I am an handy cap person
with limited income to spend on this hobby).

thank you for your help

Kelvin

I am a novice and just purchased a 7 X 12 Speedway mini lathe from
Homnier. Will attachemts from Harbour Freight tools such as the drill
chuck work in this lathe? I will also want to do some threading and
need to know what else I should purchase to do this? Any help on this
would be greatly appreciated.

Thanks,

George Kaplan

Realistically, the bearings should last close to forever; any
method of making them easy to remove would be hard to retrofit into
the existing envelope. Ejector holes don't need to be threaded;
clearance for a punch is more than enough. There are nifty blind
hole pullers that work, <
catalog.php3>, look for item 4581.
A setscrew retaining a ball bearing shouldn't bear directly on the
outer race; the point contact will distort the race enough to keep
the bearing from working properly. With an Aluminum housing, heating
the whole assembly will let the bearing drop out (differential
expansion). The outer race should actually be a minimal clearance
fit - it should be able to "creep" in the housing.
I wouldn't worry much about easy bearing replacement, this sort of
bearing mounting is relatively common and has lots of common
techniques to unmount.

Hi Roy,

Thanks for the reference. I also intend to put a BB in the compound
since the bearings are so cheap ($0.72 for a 6001-2RS) but, as a
newbie, am not sure about that design -- it looks like the press

fit

bearing could get stuck in the holder and make it difficult to

remove

since the bearing covers the bolts which retain the holder. Perhaps

a

set screw could be used instead or possibly threads for ejector
screws?

I also saw a BB design for the 7x cross slide somewhere on the net
but can't recall where - old age is hell! So, I'm adapting Steve
Bedair's 9x20 design to the 7x:


I haven't figured out exactly how I'll retain the bearing shell but
am leaning toward a set screw. I may make the holder from two
pieces, the spacer and the bearing holder, and bolt them together.
This to minimize the amount of material removed while providing
enough meat for a set screw.

I also ordered a couple of bearings with an 8mm hole to fit the
carriage drive ($0.44) so eventually all my controls will use BB's.

Given the low cost of the Asian bearings, it is surprising that

they

don't use them during original manufacture. It costs much more for
shipping than bearings when you add them later.

I'm getting ready to mod my cross slide along the lines shown

here:

At the same time I'd like to add a ball bearing to the cross

shaft.

After looking at the whole project I noted that Gordon Scott's

mod

moves the cross slide travel about an inch toward the operator

but

doesn't seem to actually increase the travel.

The cross slide lead screw has extra threads which would allow
additional travel once the material is milled away but this

would,

of

course, require a longer lead screw shaft by an inch or so on

the

knob end.

My current plan is to make an extension and bolt it onto the

existing

shaft by using a much longer screw to hold the knob in place.

This

extension will hold the ball bearing to lock the inner race to

the

shaft and a complete new part will be fabricated to hold the

outside

race of the bearing such that the original leadscrew will be

only

a

few mils farther forward than at present (this so the flange on

the

shaft won't bind against the end of the carriage).

Has anyone done a similar mod? I've found a description of a

BB

added to the cross slide on a 9x20 but haven't found this for

the

7x.

This is a more extensive (pun intended) mod to my lathe than

any

attempted previously so any advice gratefully accepted.

There is a lot to be said for Lock-Tite in these applications! Minimal
space requirement, easy assembly, and reversible with a propane torch!

I'm quite sure that I already posted this several hours ago, but here
it goes again:

Ty added ball bearings to his xslide in conjunction with a new 20 tpi
lead screw. You can find the drawings at:

Has anyone ever given thought to designing a small taper turning
attachment for one of the small 7 x 12 mini-lathes? I realize you'd
need to disconnect the cross slide screw but it just don't seem like
it'd be a big deal. I figure a cam follower on a bracket attached to
the disconnected cross slide picking up a slot milled into an angle
adjustable bracket mounted to the back of the bed. Opinions, ideas,
comments?

Not sure about the damage part but I believe this came from JWE Who may have done somthing of a turn around on these lathes as of late.

other problems with them are:

Most of them are incapable of cutting their own spindle thread.

Lack of tumbler reverse (needed for left hand threads.)

Lack of rigidity in the area of compound mounting.

To damm heavy to move easly (approx 300lbs) but to light for heavy work (lacks low/back gears.)

But I have never had one and am only repeating what I have read various places.

have an inherant set back.... Being that you can't run them for extended
periods of time without the spindle bearings over heating and causing some
sort of damage. I have been quoted a time of about an hour for maximum run
time. It didn't sound right to me but what do I know. Just thought I would
ask you guys. I am still in a toss up between the 7x14 mini-lathe from
micro mark and the HF 9x20 (maroon).

Does anyone have any experience as to how a homier compares to an old Atlas made Craftsman 109.xxxxx lathe?? I see a lot fo them go through ebay with some decent tooling in many case, and for a price that would compete with a new 7x12 homier.....then there is also the 8x14 lathemaster....I am having an indecisive moment here, and need a little help....



thanks in advance,

John

Good morning, Whether or not you'll be happy with the Homier depends
greatly on what you expect from it. All of the "Sieg" made machines,
which include Harbor Freight, Enco, Northern, Grizzly, etc, are
thought of as somewhat highly finished "kits". Most are useable out
of the box, but require some finishing to get close tolerances out
of. With all things being relatively equal, the Homier seems to be
the best deal around for $299.00, direct from Homier. I personally
have the Homier, and I'm very happy with it. It's a real 7x12 (as
opposed to the HF 7x10 which is actually only 7x8) and all of the HF
(and others) accessories will fit it. Basically there are two
options for getting the Homier, either directly from their website:
(or one of their traveling shows) or from eBay,
the person selling them on eBay seems to have some kind of drop ship
arrangement from Homier as many have seen the shipping originator as
Homier... I've had the Homier for some time now and I'm quite
pleased with it, especially after "finishing" it a little more.

Hi Des:

Little Machine Shop has a lot of neat things for the mini-lathe. I also found
their projects page that has a great diagram for making a scissors type
knurling tool. So, you should be able to get exactly what you need from LMS,
including a detailed schematic for making the knurler and its parts. BTW, the
"Projects" page link is all the way at the bottom of their pages on the left. I
didn't find it for the first dozen times I visited.

G'Day,

I keep seeing references to a company called LMS (typically in relation to

US citizens buying tooling etc)

Could someone please tell me what LMS is (preferably with a URL to their

store) so I can check some of the designs etc? (I'm looking to build my own
sissor knurling tool)

The only LMS I know is "London Missionary Society", and the railway

(L_______ Scottish Midway??)

Thanks,

LMS is Little Machine Shop. Their URL is: www.littlemachineshop.com

I purchased a Homier mini lathe a couple of weeks ago through their web site (they sell out of their Indiana warehouse, no LA outlet). All told it was $388.83 to Corona del Mar, CA.
It arrived with both shipping bolts sheared off but no damage other than a bent chip guard. At their price, its a bargain but it does have some rough edges (literally). The motor pulley on mine is eccentric .02" TIR! Today's task is to rebush it. Otherwise, I'm pleased.
