American Pacemaker - WW2 16x30 back from the dead

[Strouty]

I thought it was the same thing in a different box?

 

[86turbodsl]

Not the same.

Last summer I got some washing soda at Home Depot. It was Arm and Hammer brand. I see now a search of the HD website shows a swimming pool additive. Look for washing soda online or check at a pool store.

Powdered, automatic dishwashing detergent has a lot of Washing Soda in it. That's what I used.

You CAN convert baking soda to washing soda by baking it at 400F. See the net for details

I saw that. I used the old, it seems to be working, if slowly.

No, it's not the same stuff, though close. But no matter, it works, and works well.

The process will always be slow, this is not a dip-it-and-strip-it situation, even small parts I've usually left overnight, and on some larger parts, like the "tree" casting of my old camelback drill press, I left in for over two full days.

And, I've found that you get better results by going slow. Don't "pour the power to 'er" and hope to have the part cleaned in two hours. Dial the amperage back and give it more time.

When you try and cook it fast, the black **** that results tends to need to be scrubbed off hard, often with a wire brush or Scotchbrite. When you use a lower power over a longer time, I've found you can just rinse the **** off with a hose, with maybe only a little bristle brushing.

And all that is with just baking soda.

Doc.

My charger has 2a, 40a and 250a. There doesn't seem to be much difference between 2 and 40a. I'm leaving it on 40a. I have a nice puddle of brown mud in the tank.

That’s going to be a nice project. Nothing on that lathe that can’t be fixed. It’ll be something to be proud of when complete. And you got a good buy.

 

[ClappedOutBport]

Need pics of the other machines.... cannot tease me by mentioning a Rivett 1020s with no pix mate.

Better late than never, eh?

Man I hate image walls like that. Yeah, that will make me want to join a forum, locking everything down. Whatever.

86, have you seen this gorgeous late model pacemaker in iowa? I'm interested to see what it goes for. Looks like every penny of $6k to me.

That's from Iowa State University. It's never been used to run production!

What a creampuff.

...found some pretty good gouges on inner ways up by chuck. Obviously i need to get a couple of stones.

If they are "good gouges" the best you can hope for is knocking down any raise burr. Depending how high the burr is, you might want to start with a file.

 

[86turbodsl]

I finished getting the taper attachment all apart, soaking / spooging and such was a good call. It came apart very easy. I don't see how to get the bearings out of the little holders though. A ball peen and a punch didn't move anything. Arbor press? That's a little problematic at the moment. I have to have a good business reason to go into work.

And the bearings don't really look standard. Somebody please tell me they are standard off the shelf...

 

[ClappedOutBport]

Don't lose any. There's a good chance you may need to save them unless you're made of money.

 

[86turbodsl]

First step is to actually get them disassembled. I'm willing to improvise if cost is high.

EDIT: 24mm od, 8mm ID, 8mm wide, is a 628-2RS. Cheap on ebay. BUT, there's more width there than the 8mm. that's just bearing surface. Looks like bearings are either wider inner race than 8mm, or there's spacers on both sides. Not sure. Perfect candidate for thick shims on both sides. I'll make something work. These things are almost all frozen.

I had an idea for solving your 12" jaw issue...


Don't use it and swap us a nice D1-6 chuck for this 12.5" L-1 Buck 3 jaw.


If you're interested sent me a PM and I'll send you some more pictures.

Great idea if I actually had a d1-6 lying around.

Now that's strange. An early pacemaker with a different feedgear box.

Apologies for high jacking the thread but based on what you guys have posted for prices on some of these lathes would a 16 x 54 with a couple of chucks, some tooling and a DRO in what appears to be in good/decent shape be reasonable for $3000? I am going to look at one this afternoon hopefully if I can sneak away from work.

That would be about right for around here. Awesome lathe, hope you can get it.

This is right down the road from me if anyone's interested and wants someone to scout it out for them... Hard to tell from the bad pics and tons of goop what shape it's in, but it seems a bit pricey for a big lathe. Not that I know what I'm talking about lol...

 

[86turbodsl]

Price changed. It was 3k. 7k, no way.

[Pressingonward]

He went up in price? That's funny. $3k is pretty reasonable for a lathe around here. Junk starts at $1500. I must admit I'm always a bit jealous when I see what people in the midwest or east coast can snag for dirt cheap compared to here. I think there's just a greater inventory of industrial machinery over your way.

 

[86turbodsl]

Yes, absolutely true. Lots of iron round here.

86 - Since you were the inspiration for looking for some classic American machinery in particular the Pacemaker, I don’t know whether to thank you or curse you right now!

Here is the latest addition to the shop....





I am trying to decipher the serial number but I think it’s a 1946-47 vintage. Thanks again for the thread. I am looking forward to getting this up and running and making some chips!

The serial number or at least what is stamped on the front right way is 70175-47.

This, for sure.

Thanks!

I didn’t quite get 86’s deal but I think I faired ok. I ended up @ $2000 with an agreement to introduce the owner of the company to someone he would like to do business with....

The guys helping me load it felt bad as they couldn’t find the 3 jaw chuck so they gave me another 4 jaw L1 chuck and some indexable inserts some with carbide in them....




I ended up filling 2 of these plastic storage containers just to get them out of my truck.



My son and I are looking forward to getting this up and running and I hope it will be something he enjoys for years to come as well.

I have hi jacked ‘86’s thread enough but I just wanted to say thank you again for starting your thread as it gave me the final push to get serious about hunting for one...

Condition is everything. Better to pay a little more and not have to go through so much stuff. That was a hard learned lesson.


Sounds like you got a good deal.

 

[86turbodsl]

It's a 47. They gave it to you. That was a hell of a deal. From 7k to 2k. And it came with all that tooling and extra Chuck? Smelling like a rose you are.

Thank you for the confirmation of the date. The serial number page at Vintage Machinery seemed to imply it was somewhere between 46-47 which is why I wasn’t sure.

As for the price, my negotiation skills were not that good. They were asking $3500 and told me they were firm at $3000. When I met the owner I played a hunch as they were in the energy business and I do quite a bit of work for companies in that space. I knew someone he wanted to get to know and I told him I would make the introduction and that saved me a another thousand.
