Erich, your machine with saw removed & 2 expando drums added would look like this. You'd have to either find an original, or fabricate a pan & hood like those on the left end of this machine.

Don, you have a picture of the hood Erich would need to do an drum? Like the one you won in that big auction last week. Just to help show what we're talking about. Equipment hasn't arrived yet Bob. I'll take a pic of another unit in the HP catalog. It'll give him the idea.

Never taken one apart, but if the shaft is 3/4" all the way through the saw, I don't see why a person couldn't put 2 expanding drums on the saw end. Should be room for 2. But you'd need to fabricate a hood extension & drip pan.
I'd change out the SC grinding wheels for a couple of diamond grinding wheels tho. It's a hassle to change those inside wheels, and diamond wouldn't need to be changed nearly as often as SC wheels.

Erich, I'd make do with what you have for right now. Make sure lapidary is something you want to stick with before sinking a pile of money into it.
Fast approaching retirement age ? Wish I could say that (again). I'm fast approaching pine box age.

Fossilman Mike has grand kids that are getting into this sickness of rockhounding. You might check if he wants any.

No, I got this piece a couple days ago. It's that cast aluminum guard at the right end in the catalog pic. My big shipment (3 boxes) will be here tomorrow or Monday.

I thought so too Bob.
Hey, I just picked up one of those buffing wheel guards off of ebay the other day. Looks like it was never mounted on a machine.

Here is what your machines would have looked like new. (I have an old HP catalog)

Another suggestion. Since the older HP machines are highly sought after, If you do a very nice restoration on both machines, you could sell both & get nearly enough for a new all diamond machine. There are many of us, myself included who love the old machines, and will pay top dollar for nice ones.

Welcome aboard Erich; You'll hear many opinions on the best blades to use, so I won't try to advise you there. If the 100 & 220 grit wheels are hard grinding wheels, you'll want to start out with a 220 grit soft wheel. Then probably a 360 grit followed by 600. The end disc with the sanding round is obviously for sanding. The disc will be attached with what is called Feathering adhesive. You should be able to peel the sanding disc right off of a rubber pad under it. These discs come in many different grit sizes. Get a good selection. Since you're just starting out, I'd use the less expensive Silicon Carbide discs, instead of the expensive diamond discs. The leather disc is for final polish. It too should be attached to a rubber pad with feathering adhesive. I'd peel the old leather off & throw it away since you don't know what type of polish the previous owner was using. New elk hide discs can be bought from any lapidary supply store. I'd suggest you contact our member John at www.jsgemslapidary.com/. He can advise you on the best blades to use. He also gives our members a nice discount on supplies they buy from him. Congratulations on finding a couple of HP machines. They were some of the finest ever built. Don

My machine is scheduled to arrive next Monday. I'm hoping it might get here Saturday. I'll get pics when it gets here.
If you want a quick look, here's a link to the machine & other stuff I bought.http://www.ebay.com/itm/262124829215?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

Lets bump this one back up.
With the motor on top, and the poly arbor suspended upside down inside, I'd say your machine was built by Crown Mfg. back in the late 60's to early 70's. I have an almost identical machine on its way to me right now. The only difference being mine is an 8" model with the Poly D14 arbor. The one I got is in nearly unused condition, and still has the Crown decal on top of the hood.
The value ? Well, I gave $1,000.00 for mine, along with a Crown bead mill, a Loretone 6" saw / cabber combo, a dop pot, and a box full of 6" & 8" aluminum sanding discs, SC cloth discs to fit them, a couple of bump wheels, bunches of odds & ends and a cab preformer.
With the beautiful cleanup & replumbing you did, I wouldn't take a cent less than $400.00 for your machine. They just don't make them that good anymore.

I'm with the slag idea too. Before the EPA took complete control of our lives, many smelters would take dump truck loads of their unwanted slag & dump it in out of the way places.

Hey Chuck, here's a link to an ongoing thread about a bead mill with pics of the actual mill. forum.rocktumblinghobby.com/thread/72580/wip-marble-batchThe mill I'm getting is a little bit different, but works the same way. Hey Bob, there was a make an offer option, but it was a brand new listing & I decided to grab it while I could.

LOL. I've been watching for hoods & pans for my poly arbors. I'll probably keep that one.

Following with interest. I just picked up a bead mill with part of a lapidary estate sale.

And it's sold. Bought it myself. Always wanted a bead mill. Most of the other stuff will be serviced & resold.
