Lathe Info
I on the spur of the moment, I purchased this metal turning lathe at an auction.
Dont know the good or bad about it physically or by reputation.
Anybody on here got any opinions about this Make - Chuang Meng Machinery Co Ltd from Taiwan and Model TT-12366.
I only have the picture of the data plate for now as it is on hold to be released later.
It comes with no paperwork, but does look in good visual condition.
Is there an agent or similar in Australia???
It is my intention to upgrade from my Hercus to this...LAM lathe.jpg

Not really any info but 'LAM' was used on Lantaine lathes such as Lantaine LAM-350B and LAM-350H. So maybe a Lantaine make.

Thanks for reply.
Yes, I was scratching mhead regarding the LAM logo style title on the plate.
Google does not come up with much.
I guess I'll need to wait until I take possesion of it and am more familar with its appearance so I can see if any other lathes look the same...
I recall in the very old days of Taiwan making machinery, it was most copied from European brands such as Colchester and Arboga etc.

I rotated the pic for you.
Check the top speed on the data plate.
It says 1200 .Is 1200 rpm sufficient to drive carbide tooling if you want/wish to use it?
Echoing what steran50 said about Lantaine lathes you might look at this link for UK lathes.

Ample. I was running my Maximat at 600 rpm with a 2mm DOC on 100mm OD cast iron yesterday, using a 12mm shank CCMT insert tool. Nice finish, no dramas. Could have run a deeper cut too. I don't recall what the feed rate was but it was adequate to make a nice chip.
The Monarch CY lathe tops out at 500 rpm and I use TCT tooling all the time. Making backplates for the 'new' DS&G, 210mm OD cast iron, 0.200" DOC at 120 rpm, 25mm shank CCMT tool. A relative baby cut for that machine.

I plan to take a walk around my local Hare and Forbes outlet and see what under lathe cabinets are available.
My lathe sits on a homemade very solid wooden stand with a drawer, but not to my liking.
I will either buy one that does the job, or else I'll make one that works best...

Rather than rpm we should probably be looking at linear speed.
On a 50 mm diam workpiece 1200 RPM = 620 FPM
While it depends on the material this linear speed is on the high side even for TCT
This chart is useful

Just got back from looking at lathe stands and was not impressed.
Too flimsy, built to a very low budget and storage unimpressive.
No stand that exactly fits/suits my lathe so, I think I may consider building my own in metal and ditch the wooden stand it came with...
At least I know the storage will be strong enough to hold weight and suit my needs precisely.

Lathe Info
My lathe sits on an OEM lathe stand solely because it was supplied with the lathe. The working height is a touch low even for my smallish stature and I am contemplating fabricating a replacement tall enough to accommodate a suitable tool drawer cabinet underneath.

Well, stay tuned, somebody may offer up some pic's or ideas that could help us both.
The universal stuff INHO is junk.
Not overly expensive, but if it does not do the job right then just a waste of money really.
I have some updated pic's of my purchase, so now folks can see what I have to deal with...
I need some inspiration at this point.

I bolted a roll cab into a RHS frame under my first lathe
Will probably do likewise under my Hercus at some stage in the near future, it sits a bit on the low side on the factory mounting.

Hi Oddbod1,
A few thoughts on your frame design. Heavy wall thickness of your box section is a must.
Given that you will make your own stand one of the most pressing reasons will be comfort.
Ergonomic measurement is center height and the same as operators elbow height from what I know.
Storage is the second reason and I would follow that with cleaning.
One of the lathes I have used in the school system had a tray and it remains a favorite because of the speed and ease of cleaning.
Perhaps jacking screw mounts in the legs .
Also if you are considering coolant, now is the time to incorporate that requirement for the drainage and pump location and tank in the frame design.

Have a search of old posts as there are quite a few related to roll yer own lathe stands.
This is one that features a very similar sized lathe and something way stronger than the sheet meal offerings and covers some oif the points to thing about - storage, height etc.

This is another detailed one with plenty of photos.
