Myford ML8 Planer and Circular Saw has jammed arbor

[okeydokey]

Hi
I have just bought a creamish coloured ML8.
A garage find (they were moving house and its it not been used for - well almost living memory - not a barn find but similar if you follow.

The tailstock has a broken casting (with the slotted bit missing) so the tail can't screw in or out.
It has a Planer attachment on the outboard side of the head and Circular saw on the inboard.
The current problem is that I would like to remove the circular saw attachment - the blade/guide/table all came off easily however the arbour that holds the saw blade is firmly stuck on the spindle.
Any ideas how to remove it please and would someone kindly confirm that its unscrews clockwise? I haven't tried anything serious yet so I wont have make it tighter.
The issue is how to lock the spindle - seems a bit dodgy to use the index pin as it might break off.
Thanks in advance for your comments and hopefully a cunning plan.
regards

No, the inboard screws up clockwise - the drive of the lathe screws the spindle into the plate or chuck. If you have a faceplate for the other end of the spindle you could screw a batten across it to give something to lever against. Spray everything with penetrating oil and leave it soak.

Ah yes unscrews anticlockwise thank you - its obvious when you think twice.
Not sure I've still got an outboard faceplate good idea though - I will need to wrestle off the planer attachment that's fitted there at the moment to fit the faceplate and no doubt there will be some type of arbour or similar there but its a way. Maybe if I can take the shroud or whatever safety cover is at that end of the spindle off I might be able to grip it (the arbour or whatever's there cant look until tomorrow morning) large stilsons with leather protector comes to mind and might hold it while I do the tommy bar bit or something else on the arbour/inboard side. No doubt when I've got the arbour off there will be a similar game if I want to take the planer off - smiles.

You might be able to clamp a couple of pieces of wood across the drive belt where it drops through the stand and fix it that way (making sure the belt is a tight as possible. A little heat is a possibility, too - gently heat what you can, spray it with penetrating oil ... and LEAVE IT ALONE!

Thanks Phil will let you know -

I found that the pulley guard for the planer was held on with 2 knurled finger bolts, once removed you then have good access to the pulley and what looks like an allen key secured arbor behind the pulley abutting the headstock. Its sounds bit crude but was better than it sounds, an 18" stilson carefully held on the saw arbour and similar on the plane pulley/shaft/arbor area and with quite a bit of heave ho the saw arbor reluctantly unscrewed off. Funny thing was that there was a fibre washer in place and the thread was clean as when it was made! It screws back on fingertight until the last 1/4" when you would need tools to tighten. Almost wonder if this was a really a multi purpose setup from new similar to the a Coronet major/minor? I think later on maybe today I will try and get the planer off - glutton for punishment but better than having an unknown removable. cheers

Don't forget that the planer drive being outboard is LH threaded

 

[okeydokey]

Ah thanks - so it unscrews clockwise?

 

[Normancb]

It does indeed. All outboard bits are LH threaded so that they are self-tightening. Otherwise any load would cause the thing to unscrew. The outboard thread is 3/4 inch diameter (inboard is 1")

It's a nice lathe - have fun with it
