ok i just got a mini metal lathe for xmas and now i want to start fabing some parts for my wheely king like a solid locked diff, but im not sure if i can just pop out a diff, measure it and start cutting, i do know a little about machining so i do know how to work the thing, i was just wondering if anybody had some dimensions or a heads up on if its just as easy as like i stated before?

Any help is greatly appreciated, thx.

Awsome thx for the quick reply, looks like your fabing alot of your own parts and great job on the rear lockout, are you using aluminum? ive got a chunk of steel but the carbide i have doesnt cut it very easily i can only do like 0.005" per pass.

Tried a HSS bit? Grinding your own bits is an art and you should at last try it if you own a mini-lathe. Its a lot cheaper too.

Yes I used alloy for the lockout and spool
The axle is stainless steel

To get a high finish you want high Rpm and a carbide bit
When you use a HSS bit you have to use less Rpm with cooling
And the last thing : polish with a scotch brite

I like making my own parts

ok im kinda new at this whole manual lathe thing so could you explain what an HSS bit is? im used to cnc lathes that are already programed for me and bits are all multi use disposable so this is nothing like what i do at work.

HSS is high speed steel. Its basically a $0.50 cent piece of square stock hardened steel. You grind the profile and clearances on a bench grinder. They dull faster than a carbide bit but they only take a few seconds to resharpen. I feel they make a nicer cut and leave a nicer finish than carbide bits. You should be able to cut most steels with it.

Because you grind your own bits to whatever shape you want you can make bits for custom jobs. A bit with a small radius made on the corner of a grinder to add a radius to the adge of a part for instance.

Heres how to grind a basic bit: http://www.mini-lathe.com/Mini_lathe...l_grinding.htm
Theres tons of other info on that site too, probably specific to your lathe.
