Rebuilding a vintage Delta scroll saw from two. Gave the parts a coat of paint.

I did indeed use the 4-jaw chuck. I used a made in the USA cemented carbide tool to rough it out and then used a CCMT carbide insert tool to get it to final dimension.

Pretty much assembled. Need to wire the motor, find a light fixture similar to the original, some small tubing for the air pump and manufacture a missing jaw for the top blade clamp. It has a leather ringed piston pump to blow away the sawdust. I tried the variable speed mechanism before I painted it. The repaired pulley worked great. The speed is adjustable from 780 to 1800 spm.



Sorry for the picture quality, this new phone might be shock, dust and waterproof but the camera isn't near what the iPhone was.

It looks like quality controls is blasé about the whole thing.

Greg,
You have the wood processor up and running, I seemed to have lost track? That good friend in the back ground looks like he has over spray all over him LOL .... standing to close to the saw .....?...... more LOL


Cheers,

I made some more progress in cleaning up the dividing head that I got from Pete.  I removed the spindle to check why the lock isn't working and I think the guy that Pete got this from may have stored it in a lake.  The inside had a unique odour and was pretty manky.  The free degreaser I got came in handy

Spindle out - I need to make a wrench to remove the nut and then I can strip and clean it.  I need to replace the bolts that hold the chuck on.

I think I know why the spindle lock isn't working.  The brown stuff appears to be a mixture of old oil and grease but there is a fair bit of moisture in there.  Smells like a manky pond.

Mmmmmm...

All cleaned up.

Now I can actually see what I have to make.  If only it was as easy to make as it was to draw...

A rotary table would make that a fairly easy job.

HA... where's the facepalm icon when you need one?

May want to invest in a couple of adjustable spanner wrenches.  One that works on the face and the other that works on the diameter.

I've looked at the part several times looking for a way for a repair.

You may want to consider welding it with a TIG.  Just use some copper backing plate to keep it from ruining the function.

Another approach may be to pin the pieces together.  I'd be a real PITA to set up, but doable.  One should probably silver braze the pieces after pinning.

I don't see it being all that hard to free hand the two cuts that need to be made on the mill, a slitting saw will take care of cutting the two clamping parts loose.
