A plunge cut works just as well on a steel pully. Ian S C

Hi Pekka,

I ground a v-tool a bit sharper to match 40 degrees on my angle gauge.

Procedure is simple – set index wheel to 0 just as tool contacts the work. Plunge in 2.5mm.

Wind out, advance to slide across 2.34mm and repeat.

I made the key seats in the pulleys by filing.

For the J section poly vee pullies an 11 tpi thread chasher is a bang on fit.

I know the purists will say the angle isn't correct but been making these for ages like this.

Some pulleys run 8 hour days, 6 days a week at 9,000 rpm.

John,

I had a chemistry teacher who professed taht the only chemistry worth doing was 'bucket chemistry' – I think you share his pragmatism

Now all working. My first motor pulley rattled like hell ;-( remade it with a better fit on the spindle and whisper quiet. I'm afraid of leaving teh thing switched on without realising it!

Thank you,

MichaelG. & All. Thank you very much.

I actually have a thread mill insert, and I was eyeballing it, but it's not right pitch, nor correct angle…..

To be pedantic – I think you mean Michael Rennie . Unless you aren't referring to the 1951 classic!!!

John H ….quite so.( maybe should have corrected my "spelling /memory" by looking up the ref first)and besides my guess at the spelling of KLAATU might be worse

….but I think the sentiment is still valid.

"Gort. Klattu barado niktu!"

Did anyone else spot it on the wall of one of the offices in Close Encounters?

;-P

Hardly word perfect Gray, at least it proves I didn't cheat and look at Google first. It should be:

"Gort. Klaatu barada nikto"

Here's a cutter insert for the PolyVee enthusiasts

I wonder if they are available in the UK. ???

At a minimum order of 100 I doubt it Michael, there are not many people cutting 'V' belt pulleys at the moment and they are all on here !

There are some highly specialised tool bits from that firm and mainly for high production rate machines.

If an 11Tpi chaser does the job then OK. thats what I will use if I need to cut a pulley. I know I have one.
