Machining for port work

[Deets066]

Here's how I cut base

One pass

I really need to send you a cylinder to cut the top off of easy

I'd probly cut it off with a bandsaw first

No doubt. That would save time on the mill. If I had a gear drive lathe I might be able to do it faster.

Anyone heard of a Nishimori lathe?

Would be worth looking at for that money

 

[Mastermind]

I agree.

Only trouble is I'm don't really know what I'm looking at... Anything to look for?

Hope a machinist will chime in.

I'd check the chuck face and side runout.

 

[Deets066]

You have 3 phase power?

 

[paragonbuilder]

You have 3 phase power?

No... But that's not a problem, I can make a phase converter, or switch out the motor.

Never heard of the brand, but it sounds Japanese. And if parts are somewhat available, I'd say that's a good thing.

Old Japanese name, hard to find parts, and been sitting outside/ covered in rust. Its worth scrap minus gas money. IMO

Not with a proper cutter.

A three phase converter is nothing more than a three phase motor with a couple of capacitors .Depending on the HP a couple hundred to say 1500 microfarad electrostatic start cap and 7.5 micofarad per HP oil cap for a run cap on 240 volt .They run at around 92 percent power factor .They will start up to the HP rating of the converter and run at about three times the rating .

Being some of what an electrical savant I have 200 amp single phase in my shop .With a 5 HP converter and some " creative" transformer wiring I have 240,480,208/365 Y, three phase ,265 single phase .

I've built maybe 15 or so converters over the years .The largest was 15-20 HP .

I have an air compressor I've been building with a 10 HP motor and a 15 HP for a converter .Back burner type of project .

I got zero runout (using 0.0005 test indicator) on this one after I aligned the tailstock to the spindle. South Bend 9C-10JR, built in 1942

Things have progressed ........... added a QC, a few different chucks, a few different live centers, several different indexable cutters ................. etc

Already have a ton of .250 burrs, but they don't fit the CC Specialties Rt Angle handpiece, so I grabbed a few sets of .125 burrs. A double cut set, a single cut set, and a diamond set for reverse direction with the Foredom TX. I'd like to get a longer cable though

 

[lwhaples]

Nice box of bits! I hear ya on the cable length.

 

[Mastermind]

With a longer cable comes a bigger risk of damaging it.

Mine is some kind of Hong Kong phooey
Type but I can't remember the name.
It's not old but definitely not made in America
