Re: Hello from Yellowknife
Just
another?comment for you.
?
You
don't say where you are located, but keep in mind that the 8.5x16 lathe is only
shipped via a trucking company and they cannot be shipped via UPS due to their
shipping weight. Read the Shipping notes for that lathe on the LMS website
regarding liftgate charges.

Hey guys,
I'm about to purchase my first lathe, a
mini-lathe, and hoping for a little guidance. I will be using the lathe for
some learning and R&D in my home shop.
I was initially seeking a
7x12 lathe. However, recently I began looking for an 8x12 or 8x14 mini-lathe,
as I read that they are better (more solid, accurate, etc.) than the 7x? and
9x? series lathes. I have no clue whether that's true. I'm finding it hard to
find a selection of Canadian suppliers of 8x? units. So, now I am back to
considering the 7x12 once again.
So, a few questions:
1. Is the
Craftex CX704 lathe considered a good one in the 7x12 size?
2. When the
7x12 indicates 0-1100 and 0-2500 spindle speeds, can the lathe actually
operate at speeds as low as 20 RPM say? If so, why cannot the 10x22 model do
the same (specs indicate low ranges of 100 and 200 RPM)
3. Is the 7x12
easily CNC-able? Any idea of the cost & effort to do so? (I've already
built a CNC machine, so I'm very familiar with the much of the fundamentals,
G-code, stepper, controller, SolidWorks, etc.)
4. Does this seem like a
good starting point for somebody just learning to use a lathe (I'm a
professional engineer, 20+yrs experience, love to build stuff,
etc.)?
My limitations are the amount of floor space I wish to dedicate
to the lathe (7x12 seems great in this respect).
Any and all comments
would be welcome.
Thank
you!

Re: Hello from Yellowknife
Since I have never seen an 8x16, I cannot give an authoritative response, which also relieves me of any conflict of interest issues!? It certainly is? a nice looking machine, however. ?

Subject: [7x12minilathe] Re: Hello from Yellowknife? ? Hi Robert,
Thank you for your advice. I didn't know any of that. I went to LittleMachineShop.com. First, I saw their 7x12 deluxe, which has 2 DROs, one on the compound rest, the other on the cross-slide. As you said, they are 500W.
Then, also at LMS, I saw their 3536 HiTorque 81?2×16 Bench Lathe, and noticed the *power cross-feed*, 1.34HP, etc. Do you think that the 8.5x16 (Sieg SC4) would be a better option than the 7x12? (Shoot, OK, given that this is a 7x12 group, that will be the last question that I'll ask about that one (hopefully I didn't break the rules on my very first day...:))
Thx!

Re: Hello from Yellowknife
At
$749 the Craftex CX704 is bit pricey. It is a SIEG lathe of the older
design.
?
For
$10 more you can get the LMS HiTorque 7x12
<
?>
which
has many of the newer elements all ready on it such as:
?
Powerful 500 watt DC brushless motor
?- lots of low speed
torque
?- no brushes to deal with
?- quieter
?- full
range of speeds available with the turn of the speed adjustment
potentiometer
?- no need to change gears for HI/LO
speeds
?
No
HI/LO gears
?- often made of plastic and users break them requiring
replacement
?- quieter operation without these gears
?
True
Split nut
?- has a true split nut for power feed and threading. Some
others only have a half nut with a support
?
Cam
lock tail stock
?- Allows you to lock the tail stock down, or loosen it,
with a flip of the lever
?- No searching for a wrench to tighten or
loosen the nut
?
Port
for optional Tachometer
?-The headstock has a port for an optional plug
in tachometer,
?? this tachometer can be used on a mini mill that
has the same port
?
The LMS HiTorque is very similar to the Micromark 7x16 in features, the
LMS just has a shorter bed, and its cross feed and compound?dials are
graduated in 0.001" and 0.025 mm.
?
If bed
length is important, you may also want to take a look at the Micromark
7x16.
<
?>
It is
$100 more but it is the longest 7x lathe on the market.

Yes, it will run at 20 RPM, but the torque is minimal. If that is a
concern, get the LMS. Or get a 7x14 or 7x16. They all have motors at
least 50 percent more powerful than the 7x10's or 12's. Typically 500 watts

Re: Hello from Yellowknife
Remember, these are SMALL lathes, and turn mainly small diameters, so you
need the high end of the RPM range much more than the low end. Were I to
use my 7xs for threading, I would use the hand crank to turn the spindle.
You may find this hard to believe, but unless you have a LOT of threading
experience, you will find 20 RPM rather exciting, especially if you are
threading to a shoulder. The hand crank gives you perfect control, instant
stopping power, and high torque. When I cut threads, I use the 12x lathe,
but mainly because I'm far too lazy to swap all the change wheels on the 7X
around. Prices have doubled since I bought my machines, but the 7xs are
still easily the best buy in a small engine lathe. Expect to need to tune
them up a little, but right out of the box, they work just fine. I learned
on large old tired government surplus lathes retired when the end of WW2
took the war production pressure off, They all had slop, and we students
had to learn to deal with it. Not until I'd read a lot of books on machine
maintenance was I able to remove a lot of it. Spent a lot of time on this
after finishing the course, and returning as a "student assistant." When I
bought my first 7x10, it cost just about double what I had to pay for the
Unimat DB which was the first one metal lathe I ever owned. The 7x10 is
about 20 times the lathe that the DB is.

The Craftex looks like a Seig. Essentially the same machine as a Harbor
Freight, Mico Mark, Grizzly, and Little Machine Shop (which has a much more
powerful motor than the others.)
Yes, it will run at 20 RPM, but the torque is minimal. If that is a
concern, get the LMS. Or get a 7x14 or 7x16. They all have motors at
least 50 percent more powerful than the 7x10's or 12's. Typically 500 watts
vs. 300 in the Craftex. The LMS uses a stepper motor which is much better
at low RPM's Probably more amenable to CNC'ing, as well
Overall, they are great starter lathes, and capable of reasonable
precision. I have modified mine considerably, and as such, have not yet
outgrown it. While I have not CNC'd mine, I have put a DRO on it.

Subject: [7x12minilathe] Re: Hello from Yellowknife
Hey guys,
I'm about to purchase my first lathe, a mini-lathe, and hoping for a
little guidance. I will be using the lathe for some learning and R&D in my
home shop.
I was initially seeking a 7x12 lathe. However, recently I began looking
for an 8x12 or 8x14 mini-lathe, as I read that they are better (more solid,
accurate, etc.) than the 7x? and 9x? series lathes. I have no clue whether
that's true. I'm finding it hard to find a selection of Canadian suppliers
of 8x? units. So, now I am back to considering the 7x12 once again.
So, a few questions:
1. Is the Craftex CX704 lathe considered a good one in the 7x12 size?
2. When the 7x12 indicates 0-1100 and 0-2500 spindle speeds, can the lathe
actually operate at speeds as low as 20 RPM say? If so, why cannot the 10x22
model do the same (specs indicate low ranges of 100 and 200 RPM)
3. Is the 7x12 easily CNC-able? Any idea of the cost & effort to do so?
(I've already built a CNC machine, so I'm very familiar with the much of the
fundamentals, G-code, stepper, controller, SolidWorks, etc.)
4. Does this seem like a good starting point for somebody just learning to
use a lathe (I'm a professional engineer, 20+yrs experience, love to build
stuff, etc.)?
My limitations are the amount of floor space I wish to dedicate to the
lathe (7x12 seems great in this respect).
Any and all comments would be welcome.
Thank you!

Here's a trick I use when shopping at HF. Go to their website and find the item you want (in this case the mini lathe) and add it to your shopping cart. Then apply the 20% off coupon code. If it accepts the code, print the screen and head to the store with the coupon and the page you printed. Then you have no doubts. Works every time for me.

Re: Hello from Yellowknife
More of a Brushless DC motor than a stepper... it's bottom speed is 50RPM.
BLDC:
The Craftex is what Engineman uses:
He has he 9516 model... and he turns amazing work with that and a Taig lathe and mill.
More the crafstman than the tools me thinks...
I have the LMS with the BLDC - very nice.

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.

Hi John, This is our website and as you said there are some other products waiting to go on to it, but they are still in the developmental stage. Also the site has been set up as uk only at the moment as it makes calculating postage easier. Thanks for your email earlier reminding me of that! However we do not have a problem shipping to other countries, we just need to work out the postage costs and add that into the ordering process. If anybody does want to order anything in the meantime please use the contact us section of the site, that way i will know which countries to add second (Seems Spain is first in the cue!). You should also get an email from us.. Best Regards Simon McNally

Re: Who to install hand wheel bearings?
Yes, I have a little oil in it, enough to keep the gears wet.? I did not put a shaft seal on, I just sealed the lid to the apron with Permatex. Since I often tilt the lathe to clean it, any excess oil would run out the shaft hole. ?While ball bearings are really not necessary in such a low speed application, they are cheap, and have oil seals built in, preventing oil from leaking out if I tilt the machine to the front. ?

You would not have to fill the box,only put some in the bottom,which woud travel up all the gears. This would eliminate the need to put a seal on the shaft on the back side.

? I installed a pair of 8mm x 22mm bearings on my handwheel shaft.? Unlike most others, I put both bearings in front, with nothing in the rear.? This has worked very well for me.? See my post at:? I could not have done this mod on my lathe.? I used my Mini Mill and a boring bar. ? ? ? 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.

Interesting idea, John. I haven't followed your link, but suspect it's one I've seen before, heating the screw while compressing the acetal on to it in a vice (or vise). Should work even better with an M10 thread, where only a small amount of acetal needs?to be displaced.
?
Now, if there was a?way to take out any backlash which?developed in service by squeezing?opposite sides of your steel adapter and thus the acetal nut inside it.....?? But there probably isn't room for such refinements.

An interesting experiment would be an acetal nut. Possibly someone could try it and let the group know how it worked out...
Perhaps make a round acetal nut as described in the link below, plus a steel adapter with shape similar to the original nut but a large through hole. Turn the completed acetal nut down to fit into the adapter, press it in, then lock in place with set screws or pins. Or, the screws that hold the adapter to the CS could lock the nut in place.
< >
Based on reports from those who tried it, it works well, has little to no backlash, and doesn't wear rapidly. So far it has been used on Acme threads - the 7x12 thread would be exploring new territory.

I can produce no authority for this, but I imagine that bronze might be the best material for feedscrew nuts. Mine was originally cast iron, but as a result of certain "unintended consequences" of remachining my saddle dovetail I replaced it with one of the brass ones you kindly made and included when returning the tap, and that works just fine.
But if bronze is good for feedscrews, why not bronze half nuts on leadscrews?
Returning to G's original query, it has been suggested that he uses the adjustment which reduces backlash by rocking the feedscrew nut slightly. If his cross slide was stiff throughout its travel, that might help, but it only stiffens up at the outward end. That makes me think the cause probably lies elsewhere; hence the suggestions I put forward earlier.

I haven't looked at that nut in a long time (since I drilled the recess into it so it seats better) but is there room to put in a DIY acetyl nut?
