Thanks Tom. Now I'm not so worried about using them. One guy ended up with 8 stitches just to the right of his eye when one of the HF cast arbor plates exploded on him. His doctor told him he was lucky he didn't lose an eye it came that close.

Agree with Tom. You should be good to go. If you wanted to test them, block up the ends and put a little pressure on the center. If they're cast, they'll crack easily. I don't mean so much that you bend them, but just enough to know they won't crack in two.
As always, safety glasses/shield wise during press work. You never know what's going to come flying out. It's pretty unnerving testing a newly built press. We built a rolling head straightening press at one shop I worked in. I designed it, and over calculated everything by a factor of 4, but even then, there was a bit of pucker as I watched the pressure gage go up to the 100 tons it was built for. Did fine though. Wish I had kept all my drawings. We used it to straighten some hollow mandrels up to about 8 feet long, so we sometimes (at first, anyway) ran a chain through the part in case it broke instead of bent. Never did have one break, so I suppose the heat treaters did the temper right.

Like Tom said, you must have gotten the new improved model Ed.
I got the lumpy cast plates with my press, but again that was several years ago. I will only use them as doorstops or ballast weight.
I'm sure there is a lawyer somewhere that had something to do with the change.

A full face shield will definitely be worn when I use the press.

Ah, I'm having problems posting pictures. Yea, that's it.
Those are gorgeous arbor plates though, aren't they?

P.S. I'm taking pictures as I assemble it but last weekend was a full one and the 70 degree and sunny weather kept me out of the shop for the most part. I promise, pictures will be forthcoming, assuming I can get the picture posting problem solved.

Well this is embarrassing. It seems I somehow deleted the pictures I had taken while assembling the shop press. Not to worry though because I've decided to start over anyway. Laying in bed one night trying to get to sleep, I thought of a better way to assemble it so it ends up square. The assembly instructions just say to bolt this to that and this to that and you're done. You may be done but the thing is likely not going to be anywhere near square. I'll start over this coming weekend and be sure not to delete the pictures before I get them posted, that is if I can post them given the problems lately.

Lol, I thought I was the only one that did stuff like that.
