SLAG..  thank You. that is what I was going to do.. ( Heidbrink Minneapolis )

Gazz...  good eye.. it was listed as a torch cart but after looking up the patent number it was given to.. Jay A Heidbrink 10-23-34 ..and described as being made for gas administering tanks .. it was a device by means of which a tank containing gas to be administered to patients could be readily moved into the desired position without liability of the tank falling off the support upon which it is placed …

JT,

You are welcome.

Check out if the gas tank cart may be a valuable antique.

  There are museums that feature medical devices and instruments.

Google it or check same at a nearby medical school.

SLAG.

 

They may want the instrument.

Made some purchases today. Gentleman was a horse roper who had a barn full of interesting items and liked to buy and sell odd items. I took the advise from the forum and explained that I am a starter blacksmith and what I was in the market for. He took me to the reaches of the barn and showed me this beauty,

Motion was smooth, rust and dirt on surface, said he bought it from an old boy and was asking what he got it for. $85. Noted when I got it home the Iron City star. Reasearch led me to understand a Philly made item? Would love any information you well read gentleman could bestow. 

Also found this strange beauty looking through his shelves:

Looks to be a bench grinder/ sharpener. The shape gave me pause. Its built up in the middle. Not sure, maybe a scythe sickle sharpener? Thought for $35 not a bad purchase. 

So made a good contact, exchanged information and he was interested in the younger generation pursuing an "old-school" profession.

That kind of grinder is for double-beveled blades, so that both sides could be ground symmetrically.

Okay I was thinking about the only typical blade a wheel like that makes sense for. Say harvester knives with a single bevel on the same side of each edge of each blade(finger, tine?). Is that what you're describing John? Close?

If so I'm glad I just deleted my first couple sentences. If not I might bring them back.

Iron City is PITTSBURGH as it was the "iron City" not Philly! 

Typical grinder for an old sickle bar mower, if you search  on sickle bar mower grinder you should see a number of them---like the McCormick Deering ones.

Yeah we used to be the iron city then the steel city now the steel we have left is rusty and old and the biggest steel production is steelers fans. :rolleyes:

Finally got to start digging around in a couple of the buildings on an old farm down the road. Came across a nice 6" vice on a bench in the corner. And grabbed a wheelbarrow full of scrap. Couldnt pass up the old jack either, something about it being gear driven really stuck out. I'll come up with a use for it one day.....

Well, this didn't follow me home - it's been there all the time. A lightning strike blew up our bore pump so this pressure tank became redundant when a new set up was fitted. I could make it into a scrap art pig.

However, I am wondering if it could be used to make a tumbler for small forged pieces. Has anyone made a tumbler, and could this work?  Should be easy enough to set up with a slow motor, geared down. Any advice would be welcome.

Collie for size comparison.

Aus, be careful cutting that thing. I took a plasma cutter to a pressure tank before and learned real quick that there is a rubber bladder inside it. So be careful about that.

A bladder might be beneficial, though, if it can help reduce the noise of workpieces banging on the tank as they rotate.

Hey bryson. That gear powered floor jack is awesome.  It would be perfect for one of those old tool  restoration projects I see on youtube.

No photos, but the drop bin at my steel supplier had a couple of 15" chunks of 1½" square tube (perfect for hardy stems on tooling for the portable hole) and some nice lengths of 3/8" round bar. Ironically, I paid for them with cash I got for taking scrap to their sister firm down the road; maybe I could get them to give me a better scrap rate if I agree to get paid in vouchers I can only use at the steel yard?

There's an idea John. 

Well, on the pressure tank I was working with, I never did get it fully apart. That rubber bladder was holding the two halves together and it had more fight in it than I did.

Since posting the above, I've done a little bit of online research and discovered that there are a number of types of pressure tank bladders, which may or may not be suitable as a tumbler lining. Let us know what works.

I have changed many a bladder in a pressure and surge vessel tank and they all have one thing in common. They are all quite a bit smaller than the tank to allow the water to stretch the bladder from the inside and compressed air (typically a couple of psi below the water pump pressure) to compress it from the outside giving a reservoir of usable water pressure and stopping the pumps banging on and off every time a tap is opened.There won't be close to enough rubber to line the entire tank. 

On a side note I'm changing the bladder on a 1000 gallon (UK gallon) tank in the next couple of weeks, it's going to be a right pain in the bum.

Wow. Sounds like a bit of a drama cutting that thing. The pig is looking good.

Did very well at the industrial surplus place’s the Saturday sale: almost 200 lbs. of steel (most of which I suspect of being 4140 or similar) for $16, a nearly-new deadman switch for $21, a brand new footswitch guard for $2.50, three wire brushes ditto, and thirty pairs of respirator filters (rated for dust, welding fumes, and nuisance acid vapor) for ten bucks.

That is some haul  mate. Those old wrenches would make great twisting bars with a bit welded on. And that augur bit in the plastic is worth more than you paid for the whole lot.

 I hear Melbourne is having a bit of a heat wave at present. Well that garage sale bonanza should ease the pain!

Cut off a chunk to test for hardenability. The spark pattern was consistent with 4140 (at least to my uneducated eye), and it did harden in a water quench. 

I looked up what three pieces of 2.5” dia. x 42” long 4140 would run new, and am now really convinced I got a good deal.
