If you buy it now and stash it away, you'll make room for it a lot
sooner than first making room and then buying it.

In reply to the question about the Sherlines.  They suffer from the same
reversible leadscrew and the necessity to crank the carriage back & forth
with the LS.  I assume this is true of the Taigs, but as I don't have one, I
don't know.

Hi Ron,



Both the Craftex and Homier lathes are re-branded Siegs from China. The Sieg
7x lathes constitute the majority of the mini-lathes in the US and Canada, I
think. There are a few from the Real Bull factory, sold by Big Dog in the US
(this is beginning to sound like a farmyard). RBs differ in detail from
Siegs, and have a few minor improvements in the way of oil ports and a fairy
standard US speed control board rather than a Chinese one. Most of the
important bits are interchangeable.



Before plumping for a Taig (or a Sherline - another you might consider),
check if it is as versatile as the Chinese offerings, and will do
screwcutting, including LH threads, and pliain turning towards the
tailstock, all of which require that the leadscrew be reversed while the
spindle is still running forward. Also check if the carriage can be unlocked
from the leadscrew so it can be run quickly along the bed using an apron
handwheel working a rack and pinion.  I simply don't know if Taigs and
Sherlines offer these features.

Thanks for those titles too Andy.  Last night I put an order in to
Lindsay Books.  Arceurotrade is next on the things to do list.

I visited the Busybeetools website and was looking over their Craftex
CX04 lathe, which apparently is a re-branded Homier 7X12 lathe.  They
have it on sale at the moment for $699 (reg. $899) and I was wondering
if I should impulse buy that while it is on sale and stash it away until
I have room for it.

My preference is to buy North American or European made products, so
I've been looking at the Taig machines too.

Well I won't be buying anything much if I don't get out the door and get
to work.

Hi Ron,

As I think I mentioned in one of my emails, Arc Euro Trade stocks the
whole Workshop Practice series, at about half the price of Amazon in
the US. Arc Euro's shipping charges are reasonable, so I doubt if
shipping across the Atlantic would tip the scales in favour of
Amazon.

Some of the books in the series are more useful than others; I got one
on motors in the workshop, but I think it was written some time ago.

Three other free sources of information:

A guide to preparing the lathe once you get it:

A book for Boxford (cloned South Bend) users, which contains a good
deal of general advice on lathe operations, tools etc not specific to
Boxfords:

Lindsay books has a lot of useful shop stuff. I think they're
scheduled to shut down sometime in the not too distant future.



There are some public domain copies of a lot of the truly old stuff;
links are in the "links" section of the group.

That tends to be expensive tooling.
Lowest cost, mount a cutter in the lathe toolpost, lock the spindle and wind the saddle backwards and forwards, or make an attachment for your lathe like this, see:

The famous Model T Ford had 1/2" pipe threaded sparkplugs. The plumber's

Subject: Re: [7x12minilathe] Re: Aside from pipes and camera cable
releases where else are tapered pipe threads used?

Old flywheel style single cylinder gasoline farm engines mostly used 1/2"
pipe threaded spark plugs. (Made after the low tention spark-points in the
cylinder chamber, & before the high speed air cooled engines that became
common after WWII) Tapered threads do not give a seal unless used with pipe
dope or Teflon tape. (& other sealing methods I don't know about); Regular
threading (no taper) up to a flange & gasket is the modern norm for spark
plugs; the threads locate it, the flange & a gasket seals it. (& you can use
dope/whatever on the threads to be really sure of a seal if you want.) I am
not clear as to your need/use of tapered pipe threading...It is traditional
for iron plumbing, cheap; & for installations that are semi-permenant, IE
not have to be taken apart for a long time. Pipe thread taps & dies work
with a straight pipe, both outside & inside size; IE no previous taper
machining is needed. These taps & dies have their own built in taper, & will
do the work themselves, albeit W/ a lot of effort, either by hand, or a pipe
threading motor; but not a small lathe. Seems to me (here in Maine USA) that
these threading procedures are better done by hand, with a die/ or tap, &
only useing a lathe manually to mount/locate thease tools to get better
accuracy.
