I would point out that the way one gets experience is to do the work. You can find material in the trash beside the road if you don't have the money to just go & buy it. That is where I got mine at first. I still have the boring bar holder I made from an axle stub that broke off a hay baler. Found it in the road when I was walking to school. Tools. He already has the lathe, but he does need a grinder & some toolbit blanks.
Now, it is necessary to point out that anything you have never done, & don't know how to do, is impossible of accomplishment. That is, until you take your courage in both hands, and try & do it. generally you find that not only can you do it, but you can easily do it again. Thus the impossible becomes mundane, and learning has taken place. The hard thing for most humans to realize is that nearly anything they can imagine, they can do.

I think you will be in the minority. I used to have one of these (before it was called Classic), and it did at least get me started, and helped me re-learn what I learnt at school 25 years ago, when we used big Myfords and Harrisons!

You will probably find its limits quite early, but it is possible to produce good stuff - it just takes longer. The basic techniques are all much the same though.

Enjoy!

If you are interested in making stuff out of Aluminum, brass, steel & cast iron, you won't be in the minority very long, as you will be upgrading to a DB, SL, or #3.

Hi

Welcome to the Group
First I should warn you that the last member
admitting to owning a Uni Classic has I believe left
the building in a bit of a huff. However this is a new
year, and I assume as your profile indicates, that you
are a female hobbyist, so I'm sure we have all turned
over a new leaf and will do our best to be helpful.
Right Group???
The problem as I see it with the Classic, is the
advertising copy, and to a certain degree the price
for these smaller Uni's leads the newbie into
thinking they are more capable than they really are.
Having said that however, they seem to be well
designed and a good learning tool, and if you
approach it as a challenge, you will find it can be
a useful machine within its capabilities.
There is a group dedicated to this lathe, but the
last time I looked in on them it was a bit of a ghost
town.
Give us a try and be patient with our responses, as
even though using any size lathe has similarities,
I doubt that many members have any experience
with this model.

Regards
Art

Has anyone made gear hobs according to the instructions in chapter two
in the "Making the Most of the Unimat" book by Rex Tingey?

For those of us not at that level yet, is there a good source of gear
hobs that work on the Unimat that people recommend?

Thanks.

This must be the one he made reference to.



I always wondered (until now) if this type would work well with
a Unimat.

from my Atlas 618. All it took was a T nut in the 1/4 20 that fit the
cross slide of the UNI. If you have a 6mm socket head screw of
appropriate length, then a nut from a UNI hold-down clamp is perfect.
These are top quality CNC products. Good luck. JET

I am in need of an Adjustable Tool Post.

I make one. $65 postpaid in the 48. Pic of the one on my DB200 on request direct, off list.

Hello Clay,

Thanks for the info and a demonstration technique for the twisted best
design. I had always wondered how it was done. I suspect others had
the same question.

Best, Cary Stewart

Tim:

Mert Baker makes a very nice adjustable tool post for only $65. I don't recall his exact email address but he will no doubt see your posting and inform you.

At the risk of getting a bit OT, another bit of the memory about getting
those plied belts to lay up correctly.

As I recall, each ply is made to twist as the cord is plied. A simple
demonstration with a piece of string:

Double the length of string over, and pinch both loose ends betwixt
forefinger and thumb. Slide the tip of the forefinger over thumb,
causing both ends of the string to twist in the same direction. The
string will lay up in a two ply form. Fix the ends together with some
tape or a bulldog clip or the like.
Now, without allowing the ends to untwist, it will be found that
attempting to undo the laying up will be resisted, and the string will
spring back into the plied form.

Likewise, the belts won't come from together without the ends of each
ply being allowed to untwist.

That's all,
Clay.

Thanks for the info.

I think they spin the yarn in Z twist (anticlockwise) and ply it in S
twist, kind of pre-loading it to retain the twist.
(From dim memories, correct me if I'm wrong.)

G'day all,
It is sometimes mentioned here that the SL had more accessories than the U3 and that factor might be helpful in deciding between which one to acquire (I know, "both" would be the best answer!).

I had a quick think about it - just _what_ are those accessories that the SL has that the 3 doesn't? I mean genuine factory items. I did a search through the archives and couldn't find this question answered.

I could only come up with three that are unique to the SL, being there was no U3 equivalent (that I know of, anyway):

1) the headstock/tailstock raising blocks
2) the slow-speed attachment with the extra pulley
3) the long bed rails for longer woodworking jobs

What others were there?

Hi Brian

It appears that the center bushing has the index
pin and the internal taper to fit the WW 8mm
collets, and the main body is threaded to
accept the collet thread. I'm guessing that
instead of using a drawbar, the nose piece is
unscrewed to push on the bushing, thus closing
the collet. Did I miss something ??
I did save the pics if anyone needs them.

The collet chuck seems to be a rather elaborate item. A steel

fits inside the outer sections & the collet itself that goes inside
that.

Why would there be a separate brass centre section & not just bore

For that matter, why a separate brass nosepiece?

Both the steel main section & the brass nosepiece have a hole

into them for a c spanner or tommy bar to allow ease of removal so

it

doesn't appear that they are meant to just stay together.

In case anyone else was wondering, this is threaded M12, not M14. That rules out my interest in it!

Hello All,

A few weeks ago there was a MK4 cast iron unimat mentioned with an odd
name plate. I think it was a purposes built modified Unimat. Well it
is now bing offered in pieces. Take a look at ebay Item No.
110081268146. This is a very elaborate radius turning ficture
manufactured for some purpose. Note that it is on a cast iron carriage
that has been machined flat. Many good photos. As this was just listed
today you might take a look at some of the other interesting items
being offered by the same seller. I suspect they were all part of the
same kit.

Best, Cary Stewart
