Hi, I just received my lifting bar from Tormach and the links seem a little "wimpy y. " Perhaps they are normal. What do you guys think?

Maybe - I remember thinking they looked a bit on the weak side with the Tormach I helped move last fall, but they worked fine.
McMaster has a nice selection of shackles - and with them - they're work load rating if it helps ease your mind at all. They're surprisingly strong.

They look the same as the ones I have.
I ended up buying an expensive shackle and hook with a swivel to hang mine on due to the complexities involved in my installation. It wasn't impressive looking either and it was rated for 8,000 pounds I think? Bought from McMaster.

While I used my own lifting concoction I had these similar thoughts in an earlier post:
"Eye Bolt mounted to T slot (1/2" nut and washer slide right in). Notice the China on chain! I get a little leery, Chinese lift, Chinese chain, Chinese hooks, Chinese bolts ..."

Just to update. I had no issues getting the mill on the stand. They are obviously designed to handle the load required. However, I cant imagine it would cost much more to include thicker ones and I'm sure many people would be willing to pay a little extra for a much higher margin of safety.
Cheapest steel I can find (A36) claims roughly 48 kpsi tensile strength for 1" bar. The chain I got from Tormach (years ago) mikes 0.320" diameter, and the bar is about 0.460, so on an area basis the Tormach chain I have should handle around 5 kpsi if it's just merchant steel (as long as it's properly welded, of course). The chain appears more than adequate to handle the load, plus a more than adequate margin of safety. I'd worry (a lot) more about dangling a 3/4 ton weight on a single point lift.Quote:

Haha yes! Yes I did.Quote:
