Hi Keld

             That is a very useful addition to your workshop, and now seems to be working very well. What is the diameter of your saw blade, and how many teeth does it have?  What was the final speed in revs/min of the blade?
    I bought a double bearing spindle having a cast iron body, years ago with the intention of making a woodworking saw bench. I never got round to making it,  because I was building a garage. After seeing your metal cutting saw think I will make one similar, as I have also now got a motor.  Only thing I have not got is a lot of space.


                                                                      Cheers  David

Keld,

Nice job.

David,

If you're short of space you could make the saw as a bolt-on to your lathe,  Drive it from a pulley held in the chuck.

Dave.

Diameter 120 mm - teeth ?? maybe 100
RPM on the saw blade, ??? the motor runs 2850 and has the smallest pulley ... I think RPM (saw blade) 2000
Motor is HP 1/4 3 X 240V but running on 1 fase.

I plan to use mine for modelling wood too

Hi Keld

That looks a useful bit of equipment.  I've been thinking about building something similar.

I noticed you had a two pin plug.  Are you thinking of adding an earth (ground) connection?

Common sense is unfortunately not as common as its name suggests.

The final setup will include a "earth" in the cord - I just tested it till now.

A handy little table saw Ksor  :thumbup:

I recognise that motor ! It would have originally had resilient mounts on each end - see the castlations on the hub ? There would have been a female rubber piece that clamped around them to give slight movement.

Maybe you're right - I can't remember - the motor comes from an HP-computer disk - 2 X 10 Mb  :med: :med: :med: from the early 80'es so it's very likely that it had some rubber fasteners to eliminate the shaking.

The standard configuration was a 5 mb 'fixed platter' and a 5 mb removable one, both on the same spindle. A not entirely uncommon fault was for the heads not to retract properly, and then the customer try to pull the removable disk out with attendant destruction :) Oh happy days !

Maybe there was 2 sizes - the one I'm talking about was in fact 2 X 10 Mb - I think it had the number 7606 (not sure), but I'm sure about the 10 Mb - I have the disk now, plan to use them for a lamp  :loco: :loco: :palm:

The ones I worked on were CDC not HP so entirely probable that they were different. These were a 'step up' from the Burroughs 2 Mbyte fixed head ones - 100 read / write heads on each side of a 20 inch brass platter 1/4" thick and nickel plated. The heads 'flew' aerodynamically on the flow of air from the centre outwards as they spun, and were pressed on with pneumatic cylinders. I once had to accompany a faulty one from a hush hush military establishment with a military police escort to the factory in Manchester so that they could witness it's total destruction. It apparently had the disposition of the NATO fleet on it  :bugeye:
