Bench Grinders
I need to buy a bench grinder. B&Q sell one for about £12 - is it any good.
In particular, since my workshop is indoors, it needs to be quiet - My wife won't let me buy any more noisy tools
Are all bench grinders quiet?

No its rubbish, next to useless. Not enough power. I bought one and honestly I can file quicker.

can say the same thing even though i havent bought one myself. get a coarse and a fine file and you will do it quite quickly with half as much noise
and more accuracy. downside is you need more elbow grease than normal but hey, some exercise is never bad

That's one of the things I want a grinder for.
Really, I need a grinder, not a file

Unfortunately you need to spend more money. The B & Q stops if you press to hard.

I seem to think my bench grinder is a perf pro from B&Q and ive had no probs. Has a belt sander on other end. Sure its not the most powerful thing
but more than adequate for light hobby use. I dress up drill bits no bother.
Ill have to check exactly what make buts it scertainly a cheapo budget one. Had it for 2 years + now.

Ok, cheap B&Q is out of the question.
What is good enough?

I got one from screwfix on clearance ~£15, 9" Wolf I think and haven't had any problems - takes some time to spin up, but once it's
there it doesn't slow down.....

I have a Black and decker one it's 15 years plus old. Never given me any problems but I only use it for sharpening drills etc not as a file.
Seems to me some of the earlier posters may be using there's, with roosters tails of sparks, flying of the end of a 50*50 hollow section.
If it looks wrong it probably is wrong.

Bench grinders are a waste of time, no point gaving one in my humble opinion.
I have one and it has been used about 3 times in 10 years.
Get a belt linisher, this is ABSOLUTELY INDISPENSABLE!!!!
You can do anything a bench grinder can do on the linisher, but the bench grinder can do little that the belt linisher can do, such as squaring the
ends of exhaust tube etc, and filing decent fits on chassis tubes.
Only time a bench grinder is of any use is if you have brazed carbide cutting tools and no diamond dressing wheels, when a green stone in the grinder
will sharpen them.

I haven't got a garage yet - so I can't build any car parts yet.
I need it to do the following :
Sharpen lawnmower blades
Sharpen drills
Reform the ends of abused chisels
Various other bits and pieces

isn't it cheaper to just buy a new drill? if i'm not mistaken you're talking about drill bits getting blunt after a while?

Shame on you, trying to sharpen a drill is all part of the fun, easy if you know how, but very frustrating if you don't.
That said I do all of my grinding with an angle grinder (both 4&1/2 and 9" , I do have a bench grinder, but it's been sat on a shelf
since we moved house six years ago as I can't be arsed to wire it up.
I agree with Nat as well, can't beat a belt linisher.
DO NOT PUT ON KNOB OR BOLLOCKS!

Wait till you try and buy a new drill in the larger sizes You'll soon realize tis better to sharpen them. We learned as apprentices how to
do it, including point thinning. The knack/skill never leaves you.
If it looks wrong it probably is wrong.

well i guess 12mm is almost as big as we go on the locost and i had to change it 3 times already. once becuase i was unaware of the need for keeping
the revs constant, second because i forgot to use cutting oil, but now all goes well.. total cost? around 4€ per drill.....
by the way now that i think of it i have gone through more Drills than bits!!!!!! total of 3 knackered drills. the last one (a 2000w or so
black&Decker) is still soldiering on but smoke sometimes comes out of it

most drill wear is due to incorrect use, they normally last for a very long time.
Problem with anything over 10mm in a hand held drill is you will struggle to exert enough cutting pressure at low enough revs, so you don't
constantly form a chip, you form some chip then rub for a bit then chip again etc and its the rubbing that wears the drill not the cutting.

MMmmmm chips!
I use my grinder a lot for deburring stuff but I'm thinking of swapping it for one with a linishing belt instead of one of the stones. I find
the weak ones will slow down and can be stopped if you press on too hard but if you are not too heavy handed they do the job.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

They are quiet until you press metal against the stone at which point they become noisy

Makro were doing one that was originally £15 but now £10 (plus VAT of course) I think Netto have on for a tenner too. Plenty good enough for drill
sharpening.
I used to have a floor standing cast iron one that had 14" x 3" wheels! Bit on the loud side but great for grinding bar and tube (and my
finger on occaisions)
Keep an eye out in Aldi and Lidl - I fancy there was one advertised on one of their flyers recently.

The cheap ones are usually underpowered,you need a minimum of around 250watts, the more the better,however, having said that I have one of these,
http://www.machinemart.co.uk/shop/product/details/cbg6sb-6in-bench-grinder-with-sander/path/bench-grinders-grinding-wheels the belt is used more
than the wheel.
