RJH Ferret Grinder
« on: February 11, 2014, 06:37:47 AM »
Hi All,

 I've got one of these

 http://www.cottandco.com/media/lot/dc0f1e6dd3af5f14e6f85a80f36b8f04972f16f5.jpg

 Not this actual one but almost identical. Are you supposed to run them with the reservoir full of water?

 Cheers,

 Wilson.

It's for keeping the tool you are grinding, cool. Frequent dipping is the order of the day. Too little is counter productive.

I used one- but it had a diamond impregnated wheel- and there was oil lubrication.

Regards

Norman

Never found any ferrets in it- but I am rabbiting on :lol:

Hi Norman,

 Mine has a diamond impregnated wheel. When you say 'oil lubrication' do you mean like suds on a lathe? Continually fed with recovery from the reservoir?

Thanks,

 Wilson.

It's a long, long time ago but there were two brass pipes with taps simply dripping oil onto the face of the diamond facing.

There were, if my memory holds out, tool guides and there was a table capable of being tilted to hold tools. At that point there was no such thing as inserted carbides and so on.
Date? Perhaps 25 years ago and the venue at Gateshead Technical College. I sort of 'did' Model Engineering in an evening and a City and Guilds in Motor Vehicle Restoration as a day time manure student after retirement from the real world.

Really, the tool is not much better than a basic homemade Kennet- which I made up from part machine castings and is in the second division compared to Quorns, Stents and Clarksons which all have versatility. My opinion of course.

Cheers

Norman

My first thought was, "Why would you want to grind a ferret?"    :Doh: Then I read on. Oh it's a brand name.   :lol: 
Happy Grinding,

Hello Wilson,
Used a similar machine regularly when in mainstream engineering some 40 years ago and yes they are filled with water, you can add suds if you wish but water is fine and won't "go off" as suds will over time.

Saw a "regular" grinder once that had a little lever actuated reservoir on the under side of the wheel. The wheel was dipped in the water when running to cool the work and when stopped, it was lowered to prevent soaking.
