rectangular faceplate?

need to bore out odd shaped piece on casting i have aquired.

but don't have faceplate, i have got some 3/4" thick ali plates with holes in that i saved from bin at work.

is there any reason i couldnt use one as a faceplate?

Not really, just watch out for the spinning corners that won't be visible once its revolving.

Might be worth painting them red, so they show up better.

Likely to happen automatically, the first time you catch your hand

Seriously though: That'a an excellent idea [any bright colour will do]

Also: Double Check that the corners really do clear the lathe bed, before you switch on.

great thats a go then.

will knock corners off and paint them .

made cardboard template to check clearance and fits ok.

ICAO orange might be better, failing that, try yellow.

If you have a belt sander smooth off the cut corners so there is less chance of a nasty cut if contact is made with your hand.

If you paint the edges white can you judge the rpm from the red shift?

How do you intend to attach the plate to the lathe spindle ?

Why not roughly cut the plate to a circle and then finish it on the lathe ?

If it is ally plate as stated, should be easy enough to machine it round once mounted on the lathe spindle.

Consider taking the extra time to turn it into a permanent faceplate substitute by adding a suitable mounting boss on the back to fit the lathe spindle. Grid of tapped holes plate is often much more convenient than the conventional slotted faceplate. Especially on smaller machines. I've used the aluminium breadboards from Thor Labs for similar purposes, they have 6 mm or 1/4 UNC holes in 25 mm or 1" square pattern which works pretty well.

If your plate only has holes consider tapping them, of if they are on the large side fit some tapped bushes. Tapped holes are generally easier to deal with than fiddling about with tee nuts behind the plate. 6mm or 1/4 threads will be fine for ME size work. Especially if you have plenty of holes its easy to add another screw or two.

I'm only guessing ... but I presumed this was to be attached to a smaller faceplate, or a spare backplate.

Reason for not cutting down to a circle is: The diagonal dimension of the square might be useful.

I use this one for big jobs on the milling machine.

It is set up for work on the Pollit & Wigzell flywheel at the moment.

You made that up

No its true.

It has Wallace & Grommit valve gear as well.

Is it just me but I see signs saying

Use guards.

Do not use gloves

Would it be more to the point to have signs that says ?

Don't poke fat fingers into rotating machinery.

Be aware of your own actions

Stop machine before stuffing hands inside guard.

A bit basic really isn't it ??

Very lovely Phil.

In my humble opinion , if there's a reasonable possibility of something going wrong , then its inevitable it will do so at some point . So do not try to accomodate the problem , rather resolve it and remove the corners. Machines do not take prisoners , only victims. Have been unfortunate enough to have witnessed far too many similar life-changing events during my working life .
