Default I need a motor lathe.

I am looking for a motor lathe.

What do you guys think of 3racing and their lathes?

http://www.3racing.com.hk/products.jsp?prod_type1=Motor

What's the difference between their hku-1001 and hku-1002?

(I mean functionality wise)...

This lathe doesn't come with a slave motor, where can I get a slave motor and what makes agood slave motor?

Anyone willing to sell me a lathe can reply me also. Being very honest here, i am cheap so don't offer me anything over $120USD incl S&H.

You might want to consider searching for a twister lathe on ebay or the for sale section. They are very solid, and I wish I had one back in the day.

As for slave motors, you want something that'll run smooth at slow speeds. I think someone makes a 55 or 70 turn motor that can be run with a 6-cell pack or higher voltage. What you want to avoid is a motor with inconsistent torque, since you want the armature to spin at a consistent speed throughout the cut. Good luck in your search.

thx 071, i will look around for a "twister lathe".... since those hudy and other big name lathes are just far too expensive.

Whats the difference between a $10 carbide bit and a $85 carbide bit?

Default Need A Lathe?

I was in the same situation 5 years ago when I found an "almost" new Trinity Tru-Lathe with both carbide and diamond bits and a drive motor for $125. I really came out on top with that deal. Choosing a slave (or drive) motor depends on what type of power supply you use. I use a 4 cell Ni-Cd pack and a 27T GM stock motor, in which I set the timing to zero and replaced the bushings with bearings. That setup works great. Some people like to power their lathes with a 12 volt power supply. This requires a special type of motor (55T or so). From what I've read at www.rccars.com Integy offers really good deals on lathes. You may be able to get a new one with a carbide bit and a drive motor for $120 or less. Good luck!

I've never heard of a carbide bit costing $85. You may be talking about a diamond bit. A diamond bit will last much longer than carbide, but it is very fragile. It can be chipped with very little effort. It's best to stick with a $5-10 carbide bit. It'll give you a good cut and it can take the abuse that can destroy the diamond bit.

There's another thread where everyone has debated the relative merits of a diamond vs. carbide bit. A diamond bit is not a bit with a diamond as a tip. Rather, it is a bit which has a layer that includes diamonds, giving the tip hardness. A lot of people swear by the carbide bits, since they give a "smoother" cut. Start out with the carbide, then you don't have to worry about breaking an 85 dollar bit. Then, once you're confident with cuts then I would probably suggest going to a diamond bit. They potentially last for 1000s of cuts. One thing to watch out for.... A shinier cut does not nocessarily mean a better cut. Typically a mirror-like finish occurs when the tip is dull.

The guy stated that he didn't want to spend more than $120 for the entire setup. Do you have a Hudy you'd sell for that amount? I currently use a 5 year old Trinity Tru-Lathe and I get fantastic results. There's no reason to spend hundreds of dollars for something that does such a simple task. Nuff said?????

Whatever you get make sure you get V-guides, not ball bearings, as they can foul up. Use the search function and you'll find alot of helpful info on lathes.

Thanks for all the great advice.

Yea, what is the difference b/w the "v guides" and ball bearings model?

I realize the normal budget people allocate for a lathe is like $200, but that is really far too much for me....

I am just wondering.... if i want a "steady" lathe motor... the mabuchi 540 (or whatever that motor that comes w/ all those tamiya cars)... will that work? or a johson 540 would those work? or they are not steady enuf at slow rev for the job?

rcnewb2004 - The silver can tamiya motors would work fine. I used a 55t integy lathe motor with a 4 cells. The key is not to have the arm spinning too quickly or you'll get a crap cut. V-guides are basically solid blocks of either steal or carbide, they can wear out over time but can't foul-up with metal shavings the way bearing guides can.

p.s. - I've posted in the big jim forum asking about the off power timing question since I don't know why. I'll quote BJ in the other thread if I get a responce.

I've heard a lot of good things about Cobra lathes. They sell a well built, reasonably priced lathe that only runs about $100 new. It includes a carbide bit.

https://www.ssl-stormerhobbies.com/c....pl?pn=COB2000

And here's the integy 55 turn lathe motor. The advantage to using a motor specifically designed for lathes is that you can then use any of your standard 6 cell packs to power it, instead of needing a 4 cell pack like you would with a 27 turn motor.
