I believe I once computed that the C6J has enough capacity (in Amps, not in Farads) for a 3 HP motor, but not a 5 HP motor.

The C6J has about the same filament consumption, hence about the same...

The availability of "XL" holders was unknown to me until some weeks ago.

"The XL holders I have are labeled "Hess". Coincidence?"

LOL, indeed.

The BXA-I post has a machined area with slots every 15 degrees. The BXA-I base has matching tongues. The BXA-I base is also available with an "anti-rotation" feature.

A BXA-I system has four...

"Which should I get, an Aloris AXA or larger BXA toolpost? Both should fit, but BXA has larger tool capacity?"

"My college text book, Ebay has them as low as $8."

$8 (plus $3.95 for shipping) was for an "ex-Lib" book from England, via Amazon. Also, an older edition.

I prefer older editions as these tend...

Figure on at least 8 years of hands-on experience to become a journeyman.

Many will never achieve that distinction.

Should your concerns be focused on your 10EE, then one of Richardson's books on electric motors and their controllers is a good beginning.

In the last 100 years, electrical engineering has morphed...

Standard 10EE workholding (more or less):

1) forged 5C collet nosepiece (4,000 RPM),

2) forged 2J Hardinge-Sjogren "Speed Chuck" with smaller than normal handwheel (4,000 RPM),

3) forged 6"...

"Does anyone know if the 10ee can handle an 8" 4 jaw?"

A standard 4-jaw for the 10EE was a forged steel 8" Cushman.

Whether placed vertically, as in the photo, or placed side-by-side, the overall function is identical.

Two identical magnetic motor starters, less their overloads, are mechanically interconnected...

"As to the leads to the motor, these usually go directly from the motor controller to the windings, so opening up the motor and effecting a change there is likely to be required."

Additional considerations ...

The machine usually has a reversing magnetic motor starter, often Cutler-Hammer, but others have been found, too.

12.0" machines and accessories made after Monarch finally adopted the industry standard for 10 + 2.5" = 12.5" are not that rare. Unusual, but not that rare.

Yes still the moderator, for the time being.

"And it 'Just Works'. No failures or performance issues yet reported at all, are there?"


Yes, it does indeed "just work".

The original idea for a three- to single-phase motor conversion was...

It is Steelman-HAAS.

The conversion has been documented:

1) in a 230/460 version form (schematics), and

2) in a step-by-step form, with LOTS pf photos and the design of a special tool to...
