From the cursory glance I gave the G4003 I think it would be a versatile lathe. Gap bed, D1-4 Spindle nose w/ 1-7/16" spindle bore, hardened bed, power cross feed! Although its got a limited speed...

If you are looking for a occasional use, general purpose machine, then look at something a little larger. The capacity could come in handy, so will the gearbox. Look for something with power cross...

I have an SB 8K, but I haven't put a lot of hours on it yet. Much sturdier than the LMS 8.5x16 which I consider its direct competitor, though I don't think its worth what Grizzly is asking. I bought...

Heres a PDF about timing belts, Page T6 has a graph comparing the horse power rating of the different sizes of belts:

To summarize my jumbled thoughts, timing belts will be good for the X,Z axis and I think you could use a 5V narrow V belt for the spindle drive but I need to know your spindle motor output.

You've got the right idea for belts, we covered power transmission(belts, chains) in my last bout of schooling, Im an Apprentice Millwright.

What is your spindle motor rated at? The PolyV is a...

A very aggressive lapping may cause you problems, but Id say its easier to mess up a machine scraping than lapping. As pointed out in here the ways will naturally rub and form to each other with use....

TIG welding can be really tricky, the best thing you can do is just to take your time. I like to have around 5 tungstens sharp so I can quickly swap and keep welding. I also only sharpen one end so...

Are you TIG welding the SS sheet?, its coming together nicely!

Did you 3D print the head for mockup?

Im excited to see more from you, keep up the great work Jake!

Hey Jake, Id like to start off by saying that I have been following along with your thread and have enjoyed your build so far, wonderful work on the turret changer!

But I am concerned about your...

Hey there,

Good to see another young buck like myself interested in challenging themselves by learning new technical skills. Good luck with your project, you've got your work cut out for you but...

Good looking bull nose, and a great looking finish! Never ever polish something you can get a great machined surface on, polishing takes forever! Taking the extra time instead to do a good initial...

The inspection sheet was nice, my SC4 did come with one but it was typical china/minimal info. Grizzlies name is all over those sheets. I cant imagine them getting angry for at you for sharing it, it...

Im still here too, got all the lube I need just havent gotten a pump for the headstock. Im looking into setting up oil cups instead.

I did take a measurement of the spindle, getting into the...

The word your looking for is "extrusion", and you should look into a Bull Nose Live centre, they have a large OD for turning pipe. Though you may not find one large enough in MT2.

Im happy to hear they dont want to discontinue it, they must have sold a lot of them at this sale price. Im really hoping they keep developing it. Put a QCGB on it and it could stand up against the...

Hey, I just wanted to join in your thread because I too bought a new sb1001! I finally got it up onto my work bench last night for cleaning. Having it sit side by side with my Sieg SC4 really shows...
