Found a hiding page - 4L was 18,500 -with 25 HP and thru holes to 10 1/2" and 12 1/4" - pub dated August 1929

If you decide that is what you are looking at, I'll see about scanning these dozen...

As of 1930 the 2L was up to 7400

3L up to 12000

5L over 20K

Apologies on absent 4L

In case such info is needful - My 3J is 1.75", 22J is 2.25" and 35J is 3.5" - I think

I would imagine Hardinge would want about $1500 for a single 35J collet

(2) special collets (for P&W Jig...

Still have a "wind-up" starter (non electrical or inertial ) starter - I'll have to see if they made it

This is the one you can see the ground crew winding these up for all they are worth in old...

See post #3

If 5MT is .631 and SB is .602, the 5MT is off OVER .002 on dia per inch

Or as so well stated in Post #4

From the horses mouth. Depends on if MT5 is .602 taper per foot on dia.- too bad its .631 TPF like in here

A funny question for folks that have yet to hear about a size :confused:

Measure length of table where vise is bolted down - my 36" plain is 36" there - and not being a Dreadnought, weighs but...

Just turned down a 35/64 MT2 to .547 dia. (to suit a holder someone made ex Reed Roller Bit). Plainly plain old steel back there - HSS ate it up

And heaps and heaps of magnetos, starters and generators for the round engines of all sizes

Only if you run it too fast. When new, I doubt the spindle went much past 350. That was the way of the world then.

The photos show the vee belt drive does in fact run the spindle way too fast -...

There you go

Nope - as long as it has the "star" knob for shifting feeds on face of apron it is a Series O - which means it is not a "model A" as they came along later - even though it has the QC gearbox - and...

Can you share info for that source?

Bought a new ACME three phase dry type general purpose 3 KVA to run 1.5 HP four speed in 2001 - works perfectly "backwards" - a lash up approved by ACME. Never any issues of any kind in those twenty...

I'd guess Sebastian from the QC gear box - before their many little gear heads

The most info crammed edition of all of them - even though a bit older than 1937.

"Geared" apron - easily recognized with its clutch knob in bottom center - and the lead screw from 9B or 9A with the right length

You might first FIND OUT from folks like SB man (Ted) if such...

My all time favorite Federal is this good size ( 3" OD ? ) example that has .400" travel and is a "tenth" indicator
