Re: Rong Fu 30 z axis lock questions

The cylinder, cam on the right hand side is threaded, LHS must have clearance.
I replaced the cast iron cams on my machine with aluminium to prevent marring on the quill.

Re: Cheap Saltpeter for Stumps

Forty years ago I could have helped, worked in a chemical plant making 150 tons per day of Ammonia nitrate, interesting process.

Disassembled contactor an found insect larvae between contacts, cleaned and now working. Had to cap the air hose connecters on all my air tools, wasps love to...

Re: My Hercus 9 Restoration.

I learnt to machine on that model Lathe back in 1966 at a Perth high school, great lathe.
Bought one years later and gave excellent service, made in Adelaide, direct copy of South Bend, parts readily available at Fiora Machinery in Perth.
Good luck with the Resto.

Flea Market Score.

Purchased a Vintage Starrett Clamp for the princely price of $5 at the local flea market, possibly belonged to a tool maker of a bygone era.
Gave it a home, made the swivel stand for it, will be handy to hold small parts.
Starrett list price is $186 a pair, not cheap.

Re: Mill Chatter Fixed.

I had a Dean Smith and Grace 13X42 Lathe in Australia, no compromise on cast iron there. Reluctantly sold her when I moved to SE Asia.
Also dearly miss my Taiwanese BP clone.
I have 2 Chinese lathes, they perform their tasks but I don't have pride in ownership.

Mill Chatter Fixed.

My round head mill drill chattered when applying quill lock, annoying, found the quill was deflecting and putting the drive spline for spindle out of alignment and putting side load on the mating surfaces. Checked the clearance between quill and housing, 1.5 thou, acceptable as I use moly EP grease....

Re: What is it?

Harold inspired me to give my 1/2" Stellite drill another chance, ran the DP max speed, 2400 rpm, it was like fireworks on NYE perfectly round hole and right on size. once the heat built up it was like cutting cheese.The Drill itself is slightly discolored but is ready for another task.

Re: Electric motor capacitors

Your motor does not have a start winding, so no need for a start Cap, your motor is a permanent Cap run motor, you need a run Cap. These type of motors have poor starting torque but once up to speed they perform well. If possible mount the Cap remote from motor housing, the biggest killer for Caps i...

Re: What is it?

Tried it on a Aussie Nicholson file, ground off serrations and ran drill at approx 1000 rpm, hardly marked the file.
Tried a 1/4"carbide drill and same result.
