Anybody know of any links, or other sources, for modifying or improving Taiwan lathes.(Grizzly, Jet, Enco, etc.) HSM has one article that I know of. But I am looking for other insight.

There seems to be almost a cult of 7x10 and 7x12 owners.
First page I saw was varmint Al at.
Best thing you can do, or first thing to do with one of these machines is to get out wrenches and allen wrenches and start tightening, don't get too carried away, I don't trust these fasteners, but they can be tighter.
We have a new Clark at work, things keep coming loose, motor fell off, and pulley came loose on 3rd shift one night.
I bet I have tightened at least 30 fasteners so far. Machine seems ok excepting a cross slide leadscrew problem, we got a DRO on machine, so that isn't a problem for us, I think the dealer should fix it, but he hasn't yet.

Thanks Halfnut! I have already found Varmit Al's websight and the 7 x 10/12 webs as well. I'm specifically interested in the larger lathes. Particularly the 12 x 36 lathes. Good advise on tightening everything up though! Be safe!

Here are a few that I have found. Most deal with the smaller lathes,9x20's and 7z10's. But the information is great.
Good Luck , there is an incredable amount of info our there. weldnfab........

I bought a Grizzly single phase 3hp Tool room lathe. After about a year I decided to convert it to three phase because I wanted more speed control than was offered by the gears. I did this by using a VFD. I did not know that it would be so dificult to convert from a metric shaft (26mm) motor to a standard shaft(1 1/8") motor and still be able to use the mechanical brake and fit in the first motors foot print. You can not just change out the sheives. I ended up replacing a 3 hp single phase motor with a 7 1/2 hp three phase motor. It all worked out beautifully with a little modification to the motor mount. There are a wide assortment of metric motors available. Almost all asian lathes of a given size are made by the same factories. Many companies put their names on them and paint them their color. The internal parts are the same and are interchangable. Some times you can find a modification of one brand lathe and it will work with another companies brand. Good luck with your modifications.

There are several Yahoo groups dedicated to the 12x36 sized machines along with another dedicated to lathe modifications, Also there the 9x20 groups and various others devoted to gear cuttin and dividing and index heads

Replace every fastener you can see! Buy yourself a heap of quality M5 and M6 socket heads, bolts and grub screws. Gib adjusters, toolpost clamping bolts, tailstock clamp bolt and carriage lock for starters.
Having said that, I'm not unhappy with my little Jet 9 x 20. I've been turning out some accurate work in 316 SS and, just for the challenge, inconel http://bbs.homeshopmachinist.net//biggrin.gif Thought 316 was a bitch for work-hardening!
