Thread: What were these grinders?

I am thinking maybe one of these? Bosch Straight Grinder. #GGS6S

I know them as a strait grinder, but I know they have other names.

I did a search and they are called a strait grinder, LOL But not as big as the ones your talking about.

Power grinder

Straight Grinder

Well, how about that, still available, who would have thought. Dam dangerous things they were, my memory is probably playing tricks but I remember them as being bigger and heavier and with a 6-8" wheel. One shop competition involved lifting an angle grinder one handed straight out in front with a straight arm, all the older blokes could do it, but none managed it with the straight grinders we used.

they work great for polishing which is what I have mostly seem them used for.

I have used the Atlas Copco pneumatic straight grinders, fitted with 6 inch OD grinding wheels and also with 1 inch wide 6 inch OD wire buff wheels, they are pretty heavy and have some grunt to em Hang on and don't let it catch the wrong way unexpectedly.

Late model ones are down the bottom of the page on this link.

That would have been back in the days of Brown and Burns down in Hay Street. The bloke that lived next door to my parent's house worked there as a baker. All that light engineering has disappeared from the area. Remember Midalia and Benn, Sandovers, Brisbane and Wunderlich, all gone...

Geez, those names bring back memories, I don't remember Brown and Burns though, what were they? I remember riding my bicycle to work from Rivervale to Subiaco, I wouldn't drive that far now without a cut lunch and a thermos. Days of innocence!!!
I left Perth and my family behind in 1975, after that period of time there is no going home, so when I did return in 2000, Perth had changed and everyone I knew had died or gone, no Foys or Mortlocks anymore either, I left again in 2006 for more familiar territory.

Brown and Burns became Tip Top Bakery. Mortlocks became 78 Records. And I walk home from Murray St to near Garratt Road Bridge, about as far as Rivervale, and dodge the cyclists on the way.

A few years ago my work paid $1200 dollars for one of these to do some heavy duty polishing of a sealing (I think) surface on the inside of our Centrifuge. About half million buck machine. The grinder / polisher has not been used since.

Re the straight grinder, there has been a Hitachi version available for a number of years. Comes kitted as a grinder with guard, have seen them working 8inch buffs for polishing. Don't know if they are still available.

Sulner still have them in their catalogue I believe. They used to do a direct drive as per the photo, and flex shaft units with a big fixed motor unit driving the handpiece via a hefty flex cable. Haven't seen either in use but some of their other kit is very good at it's specialist applications.

They're also known are as snagging grinders, presumably 'cause they were used to snag castings in foundries.

Offensive weapons to be sure but a nice finish can be obtained.

Ours were Atlas Copco and were air driven.We knew them as barrel grinders,
They used a 125mm to 200mm wheel.
I have seen electrics ones
Bosch ,Metabo and Hitachi wheel size did not go above 150 diam.

a brand of barrel/straight grinder in alloy was black and decker.I have three in different sizes and they are hard work.I just purchased a hitachi and they are much lighter but dont have the outright balls of the b and d.

The British "WOLF" Co,(London) made some of these beasts in addition to many other good power tools in their day. Bought one at auction a few years ago, not sure why. Seems to have done little work, but having tried it, that's understandable. Has a wheel round 7" on it, told they were a special bond to resist shattering with rough use. Don't seem to cut very well either. Must weigh near twice as much as my Bosch 9" angle machine.
Have displayed it with a few other tools of the period, (early '60's) at our Ag. Show, and a few of the old lags can recount their experience of these. Thank heaven the bonded disc wheel was developed round then and the angle grinder became a practical tool.
