Spindle/drum sander

[wandrson]

1. why aluminum?
2. have we found a willing member to try TIGing these parts?
3. if not have we decided for or against a professional?
4. if against, where are we now?5. are Walter and Chuck willing to share their work so far (I presume there are 3d “sketches” at the least, since there was a 3d printed mockup)?

The Chuck in question is @dr_cee

1. Because it would be strong enough and MUCH cheaper (and easier to work) then the original bronze casting used
2. @LeeCJones has agreed to do the welding, but is waiting until TIG machine is repaired
3. See 2
4. Glad to share the design files

The pamphlet says State was exclusively distributed by Freeman Mfg. & Supply. Freeman seems to have moved but they are still in the greater Cleveland area and at the same 800- phone number (or 440-934-1902.)

Their website appears that they are very much in business.

Freeman also has a “local” branch in Fort Worth.

However, from their website it looks like they don’t necessarily have any parts for State sanders, except for the “abrasives”, which appear to be on “close-out”. But maybe either they can point us in the right direction or maybe we can buy some sanding (spindles?) for good prices.

Or maybe we should just consider buying a Grizzly or comparable?

Roger that.
Thank you for the update, and the share.
I can see now that I did not let the thread load fully when looking for “which Chuck”. I can see it’s been stated repeatedly. Sorry about that.

As I am unfamiliar with this machine, what purpose do the “other holes” serve? I can see there is the actuator arm “ear”, and the holes to bolt it to the spindle, but what are the others for?

@TBJK Tim, where are we on “the TIG” machine?
If I recall correctly, the “better” TIG for aluminum was the one with the bad water pump (the Synchrowave 250, I think). I think the pump had been ordered.
Where are we on that?
Anything we can do to help that along?
I know you’re buried in other projects as well, and while I’m probably not competent on a technical level, I can generally follow directions to add/remove bolts to stuff…
As for using the functional TIG machine, I think we’ve exhausted all leads (spark gap adjusted correctly is about all I know we had on that list) and it’s still not working well for Aluminum. Any other ideas/thoughts?
Should I break this into a TIG machine thread?

If your referring to the holes on the ring? They are because only half the ring is needed for the part. Since the ring represents most of the effort in machining this replacement part, from solid aluminum bar, I machined it so that we had a practise side and a used side. Chuck and I also thought the ring, when attached to the spindle, would help reduce warping during the welding process.

We still need the pump. I’m not sure if Airgas did anything with that machine or not. It is a Procon pump series 1. I don’t remember the exact model number but it’s is in the casting on the pump. The pump is not too expensive. We also need the coupling as well.

I’ve put yellow boxes around the holes in question.

I understand this will basically make 2 parts when cut in half. I think the holes are there in the original as well as the replacement, but I seem to be missing their point.
Maybe all 4 are actually used for securing it to the spindle…?

[wandrson]

Two of the four are for securing with shcs, the other two have roll pins, presumably for alignment.
