So what are you going to do about the bent lead screw and broken handle. I am a bit confused.

Bill

I'm not sure I explained myself correctly, I'll buy an other table (on that mill the table is separated).

For the broken table I'll see if I can get a news leadscrew and handle, I'll certainly have to check if
it's still parallel, if not it's a not a problem it'll go to trash or serve for other project.

The table is here: https://www.proxxon.com/en/micromot/24002.php?search#24106
it's on the bottom left, and the column plug in, it's the same column/head for the FF230and the PF230.

On the broken table side, I started to dismantle it and for now it seems only the leadscrew and faceplate
are damaged but I'll take it with me to the hackerspace to measure everything on a reference marble.

 Ok thanks, I got it now. Hopefully you will end up with two useable tables in the end  :cartwheel:

The table is totally dismantled, the screw is really.... screwed :D
The faceplate is also in pretty bad shape, the hole border are twisted.
I'll try to see if I can make a new faceplate and screw, it'll be a good exercise.
(in the meantime I'm waiting for the new table I ordered today :))

Seeing as we are having a bit of a snigger about past close escapes, here are my perennial photos of a very close escape. I wasn't there to witness the moment of near calamity (I was sweeping the floor ready to receive the machine) but nearly had kittens when I saw what had happened. This machine weighs 3 tonnes (6600lbs). Apparently this had happened to him before....

If you are ever hoisting a machine using lugs at the base of the machine don't EVER use loops slung through the lifting eye - you must use 4 individual straps, each hooked onto the eye at one end and to a lug at the other. The centre of gravity is somewhere around the table height, yet the centre of rotation is between the lugs. It's unstable, so when / if it starts to go off vertical, it runs away on you. The only thing that stopped it moving further here was the straps meeting the head / ram.

Does the mill not come with a spare parts diagram?

Rather than having to buy a complete compound table you should be able to get just the individual parts eg leadscrew, endplate and the slotted table extrusion.

As where the parts are on the way anyway....take what you learned from Keith, and give straightening that leadscrew a go!....Nothing to lose.
