Tool and Cutter Grinder Air Bearing

[Les RileyParticipant @lesriley75593]

I have acquired an air bearing for my T & C grinder. I have never played with one before, though I have sharpened flutes the basic way.

Does anyone here use one and if so could you advise me on the working pressure of the air supply please?

I too have one which I use occasionally on my Clarkson, though it's a bit big for it really.
In my case it uses very little air at all; I have a small Gast diaphragm compressor, originally for keeping +ve pressure in underground cables.
It's very similar to an airbrush compressor, but I find the air flow is so low that it gets quite hot; it really needs an air bleed.
One thing I would consider is adding a small desiccator; mine is just the little plastic bowl type, to which I've added male and female airline connectors.

Enjoy the new toy, it really is a lot easier than whatever you've used before.

Since I last used it, I've completed a small portable compressor setup using a Gast flat twin, with a 10l pressure vessel and pressure regulator switch etc.
I've yet to try it on the air spindle, but I'm sure it will be well over spec for the job.
Have a look on Ebay UK only and search for
"air compressor pressure switch control valve"
Once you get above about £9.75, you will find some controllers complete with gauges, fittings and other useful bits.

Is it a clarkson, do you have all the collets and do you have the instructions ? If not PM me ! The answer is 90 psi. Noel.

Thanks for the replies.

It is a March. However, looking at pictures of a Clarkson online, I suspect that Clarkson are only a rebranded and March are the original manufacturers.

Noel, I am sending you a PM.

I have an American "Cutwell" (sold by Brierly (sp?) ) 90 psi is required.

Do make sure that you have an airtrap in the supply line along with filter. Dry air is the best, otherwise they can rust.
