ianinsa Posted January 20, 2015 Share Posted January 20, 2015 I found this 'grinder' in a scrapyard can anyone tell me just what it is and what it's used for? Quote Link to comment Share on other sites More sharing options...

Alan Evans Posted January 20, 2015 Share Posted January 20, 2015 Yes I agree. It looks like a valve grinder for infernal combustion engines. My ex Brother in Law had one similar on the bench in his service garage…come to think of it he may still have it, I will check...

njanvilman Posted January 20, 2015 Share Posted January 20, 2015 They are mostly used today by people who work on the older cars, when things were fixed instead of just being replaced. With modern alloys for the valves and seats, they are not used in modern engines. Quote Link to comment Share on other sites More sharing options...
Alan Evans Posted January 20, 2015 Share Posted January 20, 2015 I called in to the garage on the way to the forge this morning. The valve grinder has been moved to the "I-can't-quite-bring-myself-to-throw-it-away-bin" this one was made by Black and Decker. Not used any more for the precisely the reasons njanvilman cites.

swedefiddle Posted January 20, 2015 Share Posted January 20, 2015 Good Morning, I guess what you are saying is, I am an antique. I agree with "Olt Goat", but not "Antique" In my daytime job, I use Valve grinders very regularly. As well as all the rest of every Machine Tool used in the Engine Rebuilding business. Yes it is still used on modern engines, just modern engines supposedly last longer than the ones with 500,000 miles on them. The Automobile Manufactures don't want you to maintain your car, just to buy a New One!! Ian, there must be a belt that will drive the collet shaft (that holds the valve) and another that drives the grind stone (normally the motor is on the grind stone shaft). On the other end of the grind stone shaft is another stone for dressing the stems of the valve and for refacing rockers. Just because it is a Valve Grinder, doesn't mean it can't be used for something creative!! :) :) Neil Quote Link to comment Share on other sites More sharing options...
ianinsa Posted January 20, 2015 Author Share Posted January 20, 2015 Thanks for all the replies so far, Alan your is just so similar( funny that and what happened to your camera the center of focus seems to have lost colour and gone 'sepia' ) and yes the creative is what I'm angling for..... sharpening SDS bits for use on metal?

Alan Evans Posted January 20, 2015 Share Posted January 20, 2015 My brother out law's garage serves the local rural population. But even with half a dozen mechanics, so quite a high throughput, they rebuild very few engines these days. Most are done by specialist companies or exchange units from the original manufacturer. It sounds like you work for such a specialist company Neil. The gearbox in my Volvo is not repairable, they won't sell any parts for it, you just have to buy another...The last valve I remember grinding in, with coarse and fine lapping paste (carborundum) and a rubber suction cup on the end of a dowel, was from the engine in my old 1957 MG ZB Magnette. That would have been in the early seventies. The photos seem to show up okay on mum's iPad. Is anybody else experiencing the sepia bit? I note most of the images happen to have the perfect test colours of red green and blue included! Alan Quote Link to comment Share on other sites More sharing options...
petere76 Posted January 20, 2015 Share Posted January 20, 2015 Valve grinder for sure, large Marine Diesel 2 cycle engines B&W have exhaust valves that are up to 2 feet in dia. Periodically you tear down the valves and dress the seats in a rig like you have only much larger. Old MGs and Jags had valves that you could grind true and then lap into the head to improve compression. British Layland Corp used to outfit all their dealerships with a rig like the one you have.

Alan Evans Posted January 21, 2015 Share Posted January 21, 2015 Ah I did wonder about that :) …the illusion in this instance enhanced by the autumnal leaves scattered about and the dull red/orange paint that industrial Black and Decker tools came in back in the fifties. I have been a bit paranoid about images ever since I sent off some lovely warm red photos of copper finishes to the BABA magazine. They went via an editor's PC and were published as a livid green :( very sad... Alan Quote Link to comment Share on other sites More sharing options...
swedefiddle Posted January 21, 2015 Share Posted January 21, 2015 Alan, If you want Volvo parts, let me know what you need. Neil Quote Link to comment Share on other sites More sharing options...
Alan Evans Posted January 21, 2015 Share Posted January 21, 2015 Alan, If you want Volvo parts, let me know what you need. NeilWhat an offer! But not needed at the moment thankfully, and thank you! Maybe speaking too soon, one rear disk was smelling very hot when I arrived at the forge today :( My comment was repeating the whinge my brother outlaw was having about the lack of serviceable parts on modern cars. He pointed to my old XC70 and said Volvo will not supply parts for the gearbox on that they will only supply a complete unit... I bet you are now going to say you rebuild Volvo engines and gearboxes! :) Alan Quote Link to comment Share on other sites More sharing options...
ianinsa Posted January 21, 2015 Author Share Posted January 21, 2015 Alan , on this forum you never know he might even be the "guy" that makes them and supplies Volvo . Isn't it also wonderful as to just how helpful people on this forum can be to virtual strangers... well 'virtual' friends and actual strangers.
