I must remember use the boring head for tapper turning.?

Thank you?

Looks great?

The wood lathe pulley was a necessary evil.
I salvaged the machine from the scrap pile and there was no pulley for the drive end, so i fitted a form tool to a tool block and mapped all of the features with my DRO.
All of the features including the reamed bore were done from one side without removing it from my chuck.
After the features were completed, the entire assembly was refixtured between centers to face and final turn the other side of it.
?
I had planned to remove the fixturing material until it was time for machining the last features, but decided that a little more flywheel action on the motor wasn't going to harm a thing and it got left behind.
 

I designed, machined, assembled and tested this chemical ionization electron impact ionizer for a quadrupole mass spectrometer.
304 series stainless steel, nickel screen, machinable ceramic, vespel (properties similar to teflon with less outgassing.) and ruby sapphires.
Our average hardware was 2-56 in that unit and they were assembled absolutely dry so it didn't contaminate the ultrahigh vacuum chambers they were used in for sample testing.
The cleaning process involved eighteen steps beginning with a light percentage phosphoric acid soap scrub to a final bath in heptane after a dance thru the various specific gravities in the solvent list that were done to remove any contaminants.
Cleaner than clean and 304 screws in 304 holes was gall city for sure.
Every blind tapped hole had to be cross drilled for ventilation and there were reamed fits all over it.

This was from the same arson salvage as the lathe.

Command center with an added shop built spindle indexing rig.
The control support was designed around existing holes for a collet closer assembly and used the clearance notch in the gear cover so when the rigging was removed, you can still close the cover.
A 60 tooth gear offers quite a few spacing options for a spindle and combined with my cross and end drilling rig, gives me many options to use it for.
The Hall effect tachometer is essential for optimizing cutting surface speeds controlled by my inverter.

If the tooth on the end of the bolt is ground to one side at one half gear pitch, you now have a 120 tooth gear by rotating the bolt.

Laughs, I hear ya, however, we are still talking a hand drill mounted to a boring bar holder if we are going to split hairs? grins~~~~
 

Most of what I do is Gunsmithing work.

The mini lathe is great for gunsmith? work.
The mini lathe can have a full length tapper attachment.? It work like tapper attachment from 1900.?
?
I have talk to you pass about your name? Hi again Dave?
 

It is indeed. I've got an older MicroMark 7x14 that I'll drag out of storage when I move into an apartment that isn't so tiny. I mostly use the larger lathes we have at work, because I'm not quite so limited in terms of spindle bore capacity. We have indeed talked, and you're doing great work, Dave.

I first was looking at mini lathe in 2005. Use making bushings for portable line boring work { in field } because it is light weight.? Because help reasons it did not happen. .?
?
For me it fun work?
Here a few photos off internet.?

ER32 collet chuck mods to enable it to be mounted to a milling table or an angle plate.
The 8mm holes were enlarged to accept the 3/8 inch hold down hardware for our Diamond 22 horizontal.

ER32 collet chuck on a Morse #2 shank.
The 2-3 adapter was turned straight on the OD then ground true with my Dumore toolpost grinder.
The straight shanked adapter allows me to mount the collet chuck in a Buck adjustru? lathe chuck.
The #2 shank allows use of the collet chuck on any number of my machinetools equipped with Morse tapers.

Silly project
The 20mm projectile was machined out of a part of a scrapped candlestick holder and a stainless steel bolt

Found this rusted up crusted up grinder pedestal and decided it needed a new lease on life.
After disassembly, the cast iron parts were re-machined to clean them up, the pedestal casting was glass beaded then refinished then a 1/4 horsepower water pump motor was selected to drive it.
The 6061-t6? aluminum motor pulley was machined to match the new v-belt sourced from Ebay.
Hardwood was chosen from our onsite sawmill for the base.

This was built as a functional piece of equipment with the added bonus flair of fitting into our vintage shop setting at the Machineworks.
