Anybody use the U1?

I was browsing online earlier and came across this review! I've read many of his reviews in the past, never seen this before, it's awesome! A mini horizontal/vertical mill. If only I could get one...

Nobody huh? Well damn...

I'd never heard of it before this post.

Tramming is the biggest issue that I see. There is no guarantee that the vertical spindle is at right angles to the horizontal spindle. This means that if you tram in the horizontal spindle, the vertical will then be out of tram. Even if you get the tram on both dialed in, you're likely to have alignment issues each time you move the head from one position to the other.

I'd be happy to have it as a second machine. I would use it exclusively for horizontal milling. That way, tramming and setup would not be a problem.

I would not want to have it as my only milling machine.

The throat depth in either horizontal or vertical configuration looks ridiculously small. The horizontal configuration looks tolerable, maybe close in size to the Atlas mills which seem quite popular, but the vertical looks close to unusable.

This seems to be one of Sieg's specialties: design an awesome machine, then save $5 of cast iron by taking an inch or two off one axis like a low ceiling beam you constantly crack your head on.

They have this machine listed as the G0727
G0727 Mini Horizontal/Vertical Mill

Still, I don't see the need or market for it but that's just me.

I'm with you - I just can't see the utility of such a tiny machine. It makes an X2 look big and beefy....

A tiny machine? The review says the U1 is "larger than the X2/SX2 and almost double the weight"?

It's heavier, but the work envelope is tiny. Look at the pictures on Grizzly's site, and compare the area under the cutter shaft to the size of the motor in the back. That's the same motor that the X2 uses, so you can use that to get a sense of scale.

And don't forget that horizontal milling cutters will take up a lot of that space.

The mill is so small I'm not even sure a clock maker would want it.

I need to look up the specs on its big brother as the concept isn't bad at all. I also would like to see them market the spindle as a separate product. I could see the spindle becoming a hot commodity for DIY machine builders.

It isn't just you. It is a great concept but just to darn small.

Thanks for the info guys, I didn't realise the Y travel was only 3 & 11/16 inches.

Seems a bit silly.

The head can be slid out a good bit to handle bigger stock so you can work on a big plate in 3 11/16 sections.
