He cut off the last two digits on the serial number. Those tell you the year. Should be 6193-XX.

Year will tell you a whole bunch. 2000 sounds high for that serial but might be. D1 is nice, most are L's. 10 horse should be fifties or newer. Definitely sounds worth looking into.

I wasn't aware of any Pacemakers with cam lock spindle like D1-6, not to say they don't exist, i just didn't know of any. Would love a 16x54, i thought they were 1800rpm.

Yeah most are L1 spindle. Not that it's bad, it's just unusual in this day and age. They are amazing lathes, the cream of the crop. I'd pick one up no matter what you see, they are worth saving.

My 1946 14x54 has a 10 horse, two speed motor. Both D and L spindles were offered in the catalogs, but L seems to have been significantly more popular.

It talks about spindle nose about 1/2 way down. "American" Pacemaker Lathes If your looking for a price. Go to The surplus record a used machinery dealers site and post a wanted post asking for the machine. Dealers will send you a quote if they have one on the floor. They will usually deduct 20% off that price too. Here is one on Surplus Record. 18" x 96" American #Pacemaker engine lathe, 10-1/2" SOCS, 4-jaw 15" chuck, 10 HP, #58999 for Sale | Surplus Record

You can tell the "small" from the "Big"

14 / 16 and light 20 were offered with 1000, 1500 and 2000

20 heavy was 800, 1200 and 1600 (and earlier there were also 18 and 22)

D1 on 2000 will be D1-6

Serial stamped on FRONT VERTICAL FACE of front way on right end

Like so



You can look at tail end and SEE the hard ways if its modern enough to have them

Like so



Lots of stuff here thanks to Greg Menke - like Bulletin 16 and 17

Don't hold me to this, but as I remember they put the two-speed motors only in the smallest Pacemakers, and usually if they had the 9 or 18 speed gearboxes rather than the 27 speed box.

If the machine is in good condition would 3k be a good buy?

I'm a Monarch guy, this is all news to me.

Jump on it. Now.

Go see if it matches the description before you hand over cash tho.

For context, I paid $1000 for my 20” raised 6” x 48” and $1800 for my 22” x 120” pacemakers. In Wisconsin

But they are the most wonderful machines to run. Not a vibration in them.
I’m working on metric change gears for them.

Will my CXA work on it or should I be looking for a CA?

CXA was the right size for my 12 (14 1/2 actual) P&W. Sounds small for a Pacemaker 16 (more for actual like 18 1/2)

Stick a pair of 123 blocks under it for the time being

About the sizes, it was even a part of the standard that lathes would swing 2 1/2" more than nominal. Then the marketing guys came along and that went away quick.

You need CA at least, you may want to think about a DA if you will be turning a lot of heavy stock. The larger tool holder allows for larger boring bars, one of benefits when boring large stock. There is a large increase in the cost of the holders to consider also. We run both types and are happy with both equally.

 

[gbent]

3K is a very good price if the condition is good. Since its local, that is about the same net cost as a free lathe 2,000 miles away.
I have a DA listed for sale if it comes to fruition.

Mine is an 18 speed. I believe it had the two speed motor installed because it was ordered with a relieving attachment.

I have a Dorian CXA on my 14". It works well for my use, but I'd want a CA if I was doing a lot of heavy work. I think it would definitely be too small for a 16" machine.

I went with the Dorian CXA specifically because its 1/4" taller than an Aloris CXA... the Aloris would definitely be borderline too small for my 14".
