Thanks for the i.d., james ! your exactly right the material is lot harder than petosky I thought of that idea with the metal but then a metal plate of some sort would have to cover the back of the heart, I think single stone cut hearts? done very few and they present their own challenges I would need a way to drill a hole efficiently tough to do I would imagine there is an art to grinding a heart and I still haven't got all the bugaboos smoothed out but we grind on toward that perfect heart in the sky thanks for the I/D james! next cut will be better.... Not sure about gluing a metal pale between the two heart halves. If it would stay that would be great. The metal plate could be left extended up at top and inviting to drill a hole and pass a chain. Follow ? Yes, a difficult shape to grind, an Edmostly mastered skill PS Florida and Indo coral very hard. not sure why. |

I ran vertical boring mills for several years, often had big bowls go thru the department for truing up and weld prep forming. One of the operators a couple machines down had that infamous vibration start.
He figured by filling the bowl with water he could stifle the bad vibes, which often works well. He filled it a little too full, and got a bath when he turned the machine on.

It is one of those vibrations that when you grab the edge of the bowl to stop it you are reminded of arthritis in you wrist and hand. I even tried wedging jams in the bowl to stop it from starting. Water a great idea other than the bath. |

You have to have something soft with lots of give in it to absorb the vibration, Jello would probably be ideal.

Sand does work well, but loading, and more so unloading, presents its own challenge, especially if no crane is available. Women good idea but likely a production cutting distraction.

What size vertical lathe did you operate ? Most of them are darn big. I have seen some tank ends up 22 feet across and 4 inches thick. |

I ran them from 32" Bullards to a Betts with an 18 foot table and 15 foot vertical capacity, ten different machines in that range. The larger ones had really nice hydraulic tracers on them, liked running that big stuff. One of the Niles [16' table] machines had movable columns, could cut up to a 50' diameter, I only ever had it out to about 25'.

Don't suppose mistakes were well received. Been looking at putting a drive to rotate at about 1 inch per second...redneck vertical lathe. |
