Who to install hand wheel bearings?

G.
 

When I get caught up on some bills, who installs the bearings in the saddle and cross slide of our lathes?
I won't have a lathe to do the work on, so can't do it myself. It sounds like a worthwhile mod how ever.


Re: Screwless vise

 

I am interesed in seeing your idea as I will at some point make a modification to mine.
Could you contact me off the group?
Thank you

easy trick to solve the problem of adjusting the compound. The problem is
that you normally want to adjust it with the slide in working position, but
then you have to screw the slide back to turn the two M6 capscrews and the
slide sometimes moves while you're doing that. But you can solve this
problem easily by simply putting spring washers under the heads of the
capscrews. Then you adjust the screws to hold the compound very snugly
while still letting you adjust it. I set the screws so the compound will
JUST move when I tap it with a lump of lead (which is what I use for tapping
precision surfaces). Once you get the compound where you want it, the
spring washers will hold it securely while you crank the slide back to
tighten the screws down fully.

Concerning what washers to use, you can buy Bellville-type spring-washers
from the usual sources
(). But I didn't want
to bother just to get two washers, so I used a couple of small lock washers
that I had already()
and filed off their sharp points so they wouldn't dig into the metal of the
compound.

I did this at least 10 years ago and this setup for adjusting the compound
still works fine. Of course, it's still a pain in the butt to crank the
compound back to tighten it, so a more elegant adjustment method would be
better, but this solution took 5 minutes and solves the problem of unwanted
motion of the compound, so it's good enough for me.

P.S. I have just purchased a Seig C3 7 x 14 lathe for work (scientific
instrument making) and have spent the last week getting it up to scratch.
I have been following the various threads on these small lathes. The basic
machine is good in concept but the finishing is a bit poor. I have gone
over the lathe and done some major refitting of the machine components and
some mods mainly to the saddle and especially to the compound slide
locking arrangement. Instead the lousy locking system as provided (2 M6
cap head screws) on the lathe as present and having followed the 3 point
locking arrangement that is currently being discussed, I have used a
tapered locking ring which is very affective and avoids the drilling of
angled holes through the cross slide. This system was used on an
instrument lathe (possibly Swiss) when I was an apprentice, which I found
to be elegant in use. When set up it requires hand tightening of a M3
screw to lock the compound slide solid. I will provide pictures and
drawings for those interested.

Hold a steel piece hard against the aluminum piece, no clearance, then strike the block with a common hammer, not soft or dead blow. If you don't trust this, make up a test piece to try it on first.

you know your machine so you're OK
if you work with more than one brand or type of machine the axis designations break
down fairly quickly ,they usually try to stay close to 'the book' for them but not always
so it comes down to knowing the quirks of the machine you're working on

I work on a couple mill/turns where the Y axis is mirrored ,it makes perfect sense when
you stand at the machine but most cad/cam programs will give you upside down code
(or is it backwards?)

on another they folded them over ,everything on the main spindle is right but
the sub spindle is all wrong ,until you get used to it you need a map at the machine just
to make offset adjustments and another to figure out the error messages ,if the X2 axis
has a problem it shows up as U1
never could stand that machine

Too right! I had a gallon (1.25 US gallons) can of acetone, nearly full. It?lurked?untouched in the garage for 30 years. When I eventually needed some, it was empty. The top surface?had gone rusty (condensation, probably) and there were one or two pinholes through it.

Make sure you put the acetone lid back on TIGHT!
I went to get a can down that was only two months old,and it was empty.
The lid tightened up with about a 1/16 of a turn.
Hard to believe that most of a quart evaporated out of that cap.

Re: Axis designations

Mike wrote.......Now you are really confusing me.......
?
Yes and me too. I was?taught many years ago at college and confirmed later by a manufacturer, that all axis relate to the workholder. Consider the lathe, the spindle axis holds the work. Now a vertical milling machine, the spindle holds the cutting tool, but so does a horizontal milling machine and the spindle is parallel to the bed!? Never mind slant bed machines, multi-axis machining centres etc. So the Z axis move towards and/or away from the workholder. The X & Y axis move across the workholder at right angles to each other. Not all 3 need to be used eg centre lathe and some machines have 4 or more axis eg multi-spindle machining centres. However, as we are not all professional machining companies, we don't need to get our knickers in a twist over it.

Re: Real Bull 7x14 lathe questions?

MERTON B BAKER
 

I've been using my HF 7x10 for nearly25 years. It is now fitted with a 3C
collet closer I made, and I use if for stuff that has to stay concentric,
even though taken out of the spindle & replaced when making different cuts.
True, it lacks torque at low speeds, but I never use it at low speeds, as it
shines best with small diameter work, anyway. If I had to turn a 6.5"
flywheel, I'd use the crank. Or the 12x36.

I agree with your advice. I started out with a cheap Harbor Freight
(Seig) 7x10 , and upgraded it as I increased my skills and interest in
machining. For small diameter work, they are not bad machines, and they can
be a real bargain if you are within driving distance of a Harbor Freight
store, and you have a 20% off coupon. They are store stock items, so you
can actually see it, rather than buying sight unseen.

Currently, the HF 7x10 is on sale for $499. A 20% off coupon brings that
down to $399. If you pick it up, shipping costs are zero. Even though it
is a small lathe, that is an attractive offer for the budget minded who is
otherwise looking at around $900 for an LMS, Micro Mark, or Big Dog lathe
including shipping.

Bob and others looking to buy a 7x lathe

I would not just write off any of the older lathes for the "new kid on the
block" the new top of the line Sieg type with new motor and control
technology,as sold by LMS and others. Whilst it is true that they are the
best so far and that power is more than adequate at all speeds they are
otherwise little different in design, fit and finish to all the other models
that went before them and that means weaknesses as well as strengths.

As they are sold at a premium price and have limited availability this
will undoubtedly mean a hefty shipping bill for many prospective purchasers
compared with a "lesser" model that can be bought at discount locally and
collected it might well be that they work out a great deal more expensive.

When the 7x mini-lathes first appeared the motor power of 250-300W
sometimes something of an issue, especially with large diameter parts at low
speeds, but the motors have steadily increased in power over the years and
seem to range from 350-550 depending on the vendor and model, still not as
good as the new motor Sieg (500W but higher torque) but a definite
improvement and likely to satisfy most people.

Here in the UK the premium for the new Sieg is the equivalent of $300 and
I have read it can run to that in he US too, depending on offers etc. If you
want the extra power and money is not an issue then the Sieg is the best of
the crop, but for those on a budget, who are a little less demanding or are
not averse to taking things a little slower then one of the older could make
a very good purchase and leave you change for extra tooling and accessories.
There is also of course the opportunity to look at the used market as well.

Hello, John,

Assuming I'm the Charlie you're referring to (a little presumptuous on
my part since you made such nice comments!), I'm still here. I spent
virtually the entire month of January traveling on business, including
my weekends, and wasn't even able to get downstairs to my shop until
this week. Hopefully that won't happen again. As a result, I've been
reading the digest emails but not posting.

Thanks for thinking of me; everything is OK and I should be
participating more now that the January travel craziness is over!

Best regards,
Charlie

Re: Axis designations

 

Hi Dick,
Now you are really confusing me. In message 69578 you said the on a lathe the Z axis was the long axis parallel to the lathe bed and also the spindle axis.
Now you tell me that the spindle axis determine the x axis.
Which is correct.

Ellis,
It is not the work holding arrangement but the "main spindle axis" which determines the x axis.

No, you are correct for a milling machine. The problem comes with so many layouts of modern CNC maching centres. That is why the workholding arrangement was chosen as the point of reference.
Cheers.

Re: Real Bull 7x14 lathe questions?

 

¿ªÔÆÌåÓý

I agree with your advice.? I started out with a cheap Harbor Freight (Seig) 7x10 , and upgraded it as I increased my skills and interest in machining. ?For small diameter work, they are not bad machines, and they can be a real bargain if you are within driving distance of a Harbor Freight store, and you have a 20% off coupon.? They are store stock items, so you can actually see it, rather than buying sight unseen.?

Currently, the HF 7x10 is on sale for $499.? A 20% off coupon brings that down to $399.? If you pick it up, shipping costs are zero.? Even though it is a small lathe, that is an attractive offer for the budget minded who is otherwise looking at around $900 for an LMS, Micro Mark, or Big Dog lathe including shipping.

Bob and others looking to buy a 7x lathe

I would not just write off any of the older lathes for the "new kid on the block" the new top of the line Sieg type with new motor and control technology,as sold by LMS and others. Whilst it is true that they are the best so far and that power is more than adequate at all speeds they are otherwise little different in design, fit and finish to all the other models that went before them and that means weaknesses as well as strengths.

As they are sold at a premium price and have limited availability this will undoubtedly mean a hefty shipping bill for many prospective purchasers compared with a "lesser" model that can be bought at discount locally and collected it might well be that they work out a great deal more expensive.

When the 7x mini-lathes first appeared the motor power of 250-300W sometimes something of an issue, especially with large diameter parts at low speeds, but the motors have steadily increased in power over the years and seem to range from 350-550 depending on the vendor and model, still not as good as the new motor Sieg (500W but higher torque) but a definite improvement and likely to satisfy most people.

Here in the UK the premium for the new Sieg is the equivalent of $300 and I have read it can run to that in he US too, depending on offers etc. If you want the extra power and money is not an issue then the Sieg is the best of the crop, but for those on a budget, who are a little less demanding or are not averse to taking things a little slower then one of the older could make a very good purchase and leave you change for extra tooling and accessories. There is also of course the opportunity to look at the used market as well.

Ellis,
