On a serious note. If they were small, they would drive an auxiliary
drilling spindle from the saddle of the lathe
or- and thank you- a cylindrical grinder on my Clarkson.Hmmmmmmmmm?
Or a diamond hone using a mini faceplate and paste. More Hmmmmmmmm?
Hi. These motors have been in the house over 40 years, and for nostalgic
reasons I'd like to hold on to them. They are actually large for the
power. The biggest is 31cm long, 17mm dia and heavy. Other is 25cm long,
16cm dia.They were outside under a plastic box for about two years. I
think I'm going to have to dry the windings out.
Rich, from the additional information only now supplied, I can only
assume that these are old enough to be 'clockwork' ones.
There was a QI quesion about Charles H Merz only days ago. Are you
winding us up?
...in which case, I suspect my suggestion of using them as trebuchet
ammo was right on the money.
A 40 year old mains motor that you think needs its coils drying out
before use is an accident waiting to happen.
One thing I have done with small motors is to thread the shaft and
screw on a drill chuck. I have three of these and clamp them to the
benchtop when needed. I use them for deburring holes and the like.
Sometimes I put a Procunier tapping head in the drill chuck and retap
holes after cross drilling etc. I suppose any type of tapping head
could be used but the Procunier heads just use a couple cone clutches
inside and don't self feed like a Tapmatic type would. Also, the
clutch gripping force depends on how hard the tap is pushed or pulled.
I find the best use for such things is to securely hold down some obscure
piece of floor and hold up whatever can be piled on top of them while
waiting for the anticipated urgent need or profitable sale. As a side
benefit, enough of them will prevent you from having enough space or money
to acquire useful things or do any productive work. ;-)

There is one lying idle at Daresbury, Cheshire, 5 miles from me.
It is 70 metres high and generated 20 Megavolts.
It was last used in 1983. see
