Roller Cbinet for Lathe Bench

Thoughts wanted on whether this is a good idea or not. I'm considering mounting a TU3008G lathe on one of these - https://www.tradetools.com/renegade-...Specifications This a little taller than ideal, so a platform would be needed in front to make it a suitable height to operate the lathe. May even consider replacing the castors with six custom made heavy duty adjustable feet for leveling. Concrete where it will be is very uneven. The lathe is about 300KG. Castors are supposed to be rated at about 100KG each but the castors I have seen everywhere are a bit ordinary in my opinion ..read more

Wondering if anyone here has any knowledge on stamping brass parts. We are getting a large burr on the side of our stamped parts and cannot figure out why. Got about 150 parts stamped like the part on the left then they started stamping like the part on the right (in the pictures). Bottom female cutting die is sharp and holds about three parts. Top male punch forms and cuts at the same time. Thanks! Attached Images Male punch.png (1.52 MB) Bottom.jpg (89.2 KB) Top.jpg (46.3 KB ..read more

Source for large diameter ball bearings

Hey everyone I am looking for a couple of large diameter ball bearings to forge some tooling. I'd like to make coffee scoops and some other round shaped objects. My question is if i was looking to find large diamater - say 40-60mm sized ball bearings, is there a likely kind of business that I could ask? I guess the mining industry would be one but I though someone on here might be able to give me a bit more direction on the kind of places to ask around at? I can see you can buy large diameter ball bearings on ebay and the like but I as hoping for some recycling goodness. Thanks Ian ..read more
