This pump was noisy and Mrs R complained, the pump was slung in the back of the shed awaiting sentence.

A few bits from the junkbox and a silver steel shaft to replace the 10mm ceramic shaft and some ball races (ex junkbox). The inner stainless shield and ceramic bearings were discarded although the new shaft did run fairly ok in the ceramic bearings. A very handy little grinder, just needs a simple grinding rest now.

A warning though, the rotor is jacketed in stainless steel and has sharp edges – be careful, I found out the hard way.

I have something very similar to this arrangement but I have progressed to actually having a little table on mine AND an actual toolholder – with degrees – that slides along the table. One day there is going to occur a sort of nuclear fusion/explosion in my shed and all of the bits of my T&C grinder are all going to miraculously come together in one cataclysmic event! (I hope)

I have never seen a "guard" on one of these style of grinders and I would wonder how you could actually fit one, that would be of use and not hindrance. To my recollection I have not seen one fitted to any of the Quorn grinders, not safety guards anyway.

I'm sorry if you see it that way John but as a moderator I feel a certain responsibility to MHS and more so to the beginner who may see such a post and rush out to the workshop this weekend to make a similar grinder and possibly mount a grit wheel to it.

I don't care what Roger or you for that matter what to do in your shed but when its made public I would hope the poster feels a duty of care to others who may follow suit. If they don't then thats one of the roles of a moderator.

Should I also keep quiet if someone posts a boiler that has been soft soldered from thinwall tube, no stays and has no safety valve and intends to run it at 100psi?

Nice conversion. .ceramic bearings eh…..
Does it have the speed/torque..seem to remember these things are stallable..might even be an advantage….

"Why oh why do people who have nothing to offer the post and have nothing else to boast about just jump in to keep their name alive?"

Well out of order John. Sounds like 'a moment of madness' to me and for very obvious reasons concerning Jason – but we've all done that! Jason's contribution to this forum is immense – think you should apologise…just my opinion.

Looks very nice Roger.

Regards,

Allan.

Hey, let's not start a flame war here! Jason and John have both explained their positions. It's reasonable for Jason to comment on the guarding as beginners do copy what they see on this forum and in print. It's also fair comment by John that the poster could have been contacted by PM instead.

The rest of the comments are just distracting us from the point, which is that Roger has done a nice bit of recycling.

Dare I say it, I run a diamond bonded wheel without a guard – it's 95% solid aluminium and is not going to burst explosively. At the other end of the spindle is a grit wheel, in a guard. I also wear safety goggles whenever using it.

Finally, what we do in our own workshops is our own business, but in my previous job I was very struck that the employees who took safety most seriously were the youngest ones. I never had anyone under 30 question the need for risk assessments, fire drills or safety gear – but I did get them reporting near misses and potential hazards.

Neil

FWIW my little study today shows that 1.3% of MEW articles are about safety., published at a rate of about two a year.

Hi Neil

I guess we all see these things differently. For me John's post was over the top and offensive and am quite surprised and disappointed it could be seen otherwise or ignored.. Amazed even!

Ignoring this kind of behaviour leads to more of it.

Not for me this..

Bye.

Well I decided to make a cover for my new surface plate, bit of quarter ply and couple of lats around the edge. Nothing small enough so get out my little saw and rip some 2×1:

And this is the safe way to store these saws when it's not in your hand:

I am amazed at the mirth generated by this post. The OP had just modified a central heating pump to make a motor for driving a diamond abrasive wheel. It was not a finished project just a report on the conversion of a clapped out pump into a potentially useful grinding set up. For me the OP should be applauded for his original thinking.

If I put my negative H&S hat on then the big danger I see is actually the rather long, thin unsupported shaft carrying the diamond abrasive wheel. This could bend and buckle if there was the slightest imbalance in the grinding wheel!!!!

Calm down, have another glass of wine (but don't go into the workshop afterwards!!!!), relax. Enjoy the ingenuity in re-purposing a redundant pump into a motor.

Personally I'd be very careful, that 1/20 HP motor is liable to rip someone leg off.

Now that IS funny!

Just wondering where the rest of the mirth is as alluded to by Mike Cox there? I do have a bit of a reputation of being a bit slow on the uptake though I would be grateful if someone would explain the joke to me? Anyone?

I don’t recall where any moderator with a duty of care to the forum owners has advised suitable guards to accompany the hundreds of unguarded lathe chuck and milling chuck pictures. These belittling safety cautions grind my gears.

And to say the safety warning is there to protect beginners is laughable. What, are these beginners 7 year olds. Get real guys.

Take care y’all.

What a good idea Roger would never thought of doing that with an old pump great idea, as for the rest of this thread I kind of see both sides of the argument, for me though I would like to think anyone that has the know how to make that would also be wise enough to know whether it needs a guard, not having a pop at Jason though as stated can see both sides, I wish sometimes though people would not get involved, I'm sure if Roger was pissed of with Jason's comment he would have said so, so no need for anyone else to get involved no matter what there thoughts are.

Life's to short.

It's what you do when that motor has ripped your leg off (though you might not be laughing very loud)

If you really want to know ( and when you find out you probably won't ) HERE is the explanation along with others of similar depth and interest.

All part of today's vibrant and erudite language.

Well thank you all, I had not intended to stir things up so much. The motor runs about 1500rpm and rated about 100Watts and is OK for sharpening small drills, gravers etc – so you work from the front and likely to be out of line of fire in the unlikely event of a lump flying off. I can fit a small aloxite wheel but it is more trouble than it's worth – I use a conventional guarded grinder – with proper guides etc. Nevertheless something could go wrong and risk is always worth pointing out, I am certainly not pissed off with advice.

I have been tinkering for well over 60 years and worked in industry long before H&S was a big deal, people got hurt and little or no compo for it – you learned to look out for yourself and your mates. Most of my work now is on a 6mm watchmaker lathe or an ML10 (with looseish belts) and a 1940s sensitive drill and the worst I get (so far) is a (rare) whack on the knuckles from a chuck jaw or what is left of my hair caught in the drill belt and I do wear eyeshields when I feel nervous or the swarf flies about. So to all, stay safe, think 'what could go wrong', some of you use much bigger kit, a visit to A&E is very boring. Finally, the grinder in my first job was an old series motor and open wheel loosely screwed to the wall at face height – that was a bit scary.
