Firstly - is motor running right direction?

Remove side plate to see that ram is going SLOWER on the cutting stroke and FASTER on the return stroke (the crank pin on the bull gear will be in...

Here is recent availability - see Post #9

New to me P&W 1694 12x54

Not for Cinc, but had to make the clutch. This was just a modified off the shelf forged machine crank

Have 2KM / 3 KM manual that can be emailed if you care to private message me that email address. The KM was a few years prior to yours

Old "M" Monarch - gives an idea how many pieces the shaft assy consists of

315541

In your minds eye you can imagine the PILE of special tools Monarch had to invent for this job

Maybe 1200 max - all done with motor sheave and appropriate length belts. In other words, you could probably have a 1942 CK with less than 500 top end. Depended entirely on what the original...

As near as I know all such clutches are "right - tight" and "left- loose"

Be selective

Oldies are "slope heads' - unlike the "square" one the dealer did not have - photo in this thread

These later ones have the hard ways - and often go faster speed wise

They were...

Probably have to rig up a tool to bump it loose - pair of hard wood jaws to fit knob and on out from there so you can un-stick it

almost never stuck ENGAGED

"Dual Drive" combines both geared speeds and belt speeds - may go there

The 14" Monarch may go there - its likely to be the 12" that swings 14 1/2"

Maybe you should ASK seller?

Lots of info...

Gives an idea of age - image scanned from approx 1910 catalog of the 18" Standard

Its a 13 Heavy Duty RP and the "air thing" used to operate a collet system I suppose. The collet closer is the piece LARGER than the spindle nose threads

The 626 says it is from 1942

What ever...

CMM (the milling machine folks) liked 5/32 per foot on their taper gibs

Taft Peirce #1. The very best in my opinion and I have had mine for about 25 years. They are 5 X 12

Made in Woonsocket, Rhode Island

On page 86 in second pub

Taft-Peirce Mfg. Co. -...

A guess might be weld bevel maker for good size pipe

I'd guess really old (NMT50 goes back to circa 1928) but never used

Why?

Straight cut teeth - almost unheard of only a bit later - and helical instead

To me, its the stuff that can be removed easily - like on this cast iron. If this lathe bed was steel, it would be a much more issue

Don't neglect to turn it the right way...UNDO is up and away from you :D

Assuming you refer to common vee belts......LOOK on belt for a number - like B90 (or BX90). Purchase belts with the same number

Any honing shops in that part of the world? Texas Honing in North Houston does 20 footers every day, but the shipping won't be cheap

You could look on VM for the latest dial type number 2 weight and use that as an educated guess since the DTs where the heaviest

Or.....42/56 = .75 and 40 times .75 = 30

If it has T/A or the mounting bolt holes maybe you can provide Mark with some T/A dimensions related to its mounting on carriage saddle. While you are at it, say length of carriage saddle

Both my full line catalogs ('39 and '40) have one teeny photo of it back there mounting coolant piping for whatever reason

PDF page 12 shows back of Series O apron clutch - I'll guess its worn out gears - the worm and its gear
