Sieg C3 vs SC3

 

"For ME, I would absolutely go with the longer bed.? That distance can gets used up pretty fast with a chuck in the headstock, work piece, drill, and Jacobs chuck in the tail stock.? I also like a longer bed so I can move the tailstock further out of my way when not using it."

I agree completely, but I worked for years (and made several large projects), with a Harbor Freight 7x10, and there are ways to get around bed-length problems. (And these ways are worth knowing about no matter how big your lathe is). A drill in the tailstock doesn't HAVE to be in a chuck. You can drill a pilot hole with a small drill in the chuck, then hold your big drill on the tailstock center with a lathe dog on the drill shaft to keep it from turning. (And that center can be a homemade short one that hardly sticks out, not the giant centers you buy). When drilling from the tail stock, you can also shorten drills by simply sawing off the shaft -- they aren't hardened.

Also, many things held in a chuck can instead be held on the faceplate. Most people used the faceplate for holding odd-shaped things that won't fit in the chuck, but if you're bed-challenged, you can also use it to save the ~2" of bed length that a chuck uses up.

Eventually I bought a longer bed for my 7x10 from little machine shop, but I don't regret my original purchase of the short bed. It helped develop my ingenuity.

I'm not completely expert in the differences and just rambling from memory.

But first, I don't think anybody can say if lathe X is better than lathe Y - for YOU.

It is my understanding that the SC3 has a better motor arrangement and also a longer bed (7x16 instead of 7x14).

For ME, I would absolutely go with the longer bed.? That distance can gets used up pretty fast with a chuck in the headstock, work piece, drill, and Jacobs chuck in the tail stock.? I also like a longer bed so I can move the tailstock further out of my way when not using it.

But plenty are fine with the various shorter bed models.

Another thing I think about is the cost of the tooling.? And how I would feel paying the same money for tooling (chucks, better tool post, and on and on) for the lathe I didn't really want versus the lathe I really did want.? So, I suggest it is often best to go for the most machine you reasonably can unless cost is absolutely a major factor.

That would also mean looking at options other than C3 versus SC3 and perhaps other lathes.

Jump in it's a great hobby, you and me are on the same plane, This group has such a great amount of knowledge you can't go wrong.

Hi Old Boilermaker, I thought they killed us all off.

One thing to keep in mind no matter which you end up with, these things wind up being more of a kit than a finished product right out of the crate. You will invariably be fixing and adjusting things from the get go.

Re: Sieg C3 vs SC3

 

Having spent decades regretting buying the cheaper version of a tool instead of the slightly more expensive version with an added feature I'd love to have, I agree with the idea of buy the best you can find!

I got mine for a pittance at a flea market years ago! One of its virtues is the way it nicely fits into a shop apron pocket for ready availability.
