Sometimes you just gotta laugh..

John Hill:
I was over looking at another site where someone is asking about low speeds for his lathe, thread cutting and big diameter work.  He is asking about VFDs and such like and there is quite a discussion going on.  I suggested turning up a smaller pulley for his existing motor or even making a pair of step pulleys,  ha ha, that seems to have gone over like a lead balloon! :coffee:

John,

It seems in some of the higher circles of model engineering, simplicity isn't the correct answer, but mention huge wads of cash to cure a problem, and their ears prick up and decide it is the only way to go.

I think their motto is 'Can't have the riff-raff telling us anything, it lowers the tone of the discussion'.

Remember me talking about machine polishers.

John Hill:
John, you are so right, thats exactly what it is.  The activity is not to make something but to collect the brightest and best equipment possible so that 'one day' you might be able to make something! ::)

He he, I am sort of holding my breath for someone to ask where you could buy a low speed pulley!  (He has a lathe, you know?)

John Stevenson:
The one that make me laugh is not the guy who posts something very simple like a angle plate what doubles up as a gizmo.
Three pictures from all angles and some twonk wants working engineering drawings of it.

Can't even a beginner workout something this simple give the pictures? Chances are his machine is different anyway so he's have to modify said drawings.

I have to admit fitting a 3 phase motor and using a VDF does seem like a nice idea, esp on my mill where I seem to be constantly changing the belts.

The other way would be to fit a permanent magnet motor with a controller, like the mini lathe. But I like the 3phase better.

Where's the way out door smiley  ::)
