I have an old saw and the part where the blade sits on has a screw stuck in it so I need an engineer to get it out for me. Can anyone help please?

Hi Claire it would help if you can give a little more information ie what type of saw and which end of the saw is damaged a locality of where you are would help.

Claire,

What sort of saw? Engineers hacksaw, presumably but could be a jewellers, coping or other type? Can you describe it? This applies to all queries; give as much info as possible and/or photo, to boost possible number of responses. I mean this to be helpful, not critical.

John

It’s a printers saw. Am in Leeds, but my dad lives in London (it’s my dads saw).

Wait for Claire to verify, but pictures on the net look similar to a table saw, 5 or 7" diameter sitting in a big heavy cast iron base. It looks like rotation is normal (Anticlockwise looking on the nut). so should be a normal RH thread.

I think Claire has the saw in her possession by the way she has worded the request so presumably in Leeds !

If the screw isn’t totally mangled get some heat on the part, 100℃ or so and add a dab of diesel. Let it soak in for a while 30 mins, and try removing screw with screwdriver, Allen key, mole grips, whatever. Maybe add some more heat and repeat a couple of times. If it’s surrounded by plastic, you’re out of luck.

If the screw has become overtight through the rotation of the spindle then "shock loading" might be the answer ie hit the allen key, etc.

Possibly lead strips?

When someone knows for sure whether it is a clockwise or anticlockwise screw, an impulse driver might do the trick. Otherwise drill with the appropriate left or right handed drill(s).

Michael G:

Thank for the link. I did actually glance at the linked page before posing my question; knowing next to nothing about printing, however, I came away without the answer.

As a schoolboy I recall a visit to the Clarendon Press in Oxford and being impressed by the enormous volume of noise from the (?) linotype machines.

Sorry ega, I hadn’t noticed that the question was yours ... I was responding to ndiy’s post.

The answer is ‘type metal’ [such as that used for Linotype], not Lead.

This page [next stop on the circuitous route] links several instruction books and patents: **LINK**

That’s rather cryptic, Steve

... Could you please elaborate ?

I hope to hear that someone can help the OP but in the meantime was interested to read some of the material linked by MichaelG.

It seems that some of these old printer's saws had a sliding table immediately to the left of the blade which is the same configuration adopted by modern woodworking saws.
