Watch your fingers. And dont put anything you value under it when cutting. Just you wait until it grabs for the first time


robertst - 30/5/06 at 11:55 AM

also bought a kevlar jockstrap just in case for the delicate family jewels.

sorry to be boring but always wear a full face mask when using a 9" grinder I saw a lad have one jump at him causing a 6" cut in his chin, use but with respect.

And thick gloves/welding gauntlets.

Unless you fancy a finger that looks like Calvin's!

And ear-defenders too if you've any sense!


Cheers,
James

Those grinders are great. i used one with a diamond blade once for cutting a clay waste pipe underground. The bugger grabbed and pulled out of my hand. Luckily it only went forwards and stopped soon after.

Had to go inside to change after that!!!!!

And make sure the sparks go straight down. I got carried away the first time and set fire to my jeans!

When I was a foundry worker one of the fettlers lost his right thumb to one. They put it back for him but he couldn't bend it after so it was more of a cosmetic procedure.


robertst - 30/5/06 at 09:37 PM

had my first problem. didnt really realize how far back the sparks could fly and they all hit my window and buggered it all... oops! parents were pretty mad i screwed up a double-glazing window. told them it was the dog
apart from that... pretty scary but now that i dont need to cut 3mm thick tube anymore i can change it for a good small Black and decker. the one i had before lasted exactly 8 minutes before burning out from exhaustion

For a 41/2" angle grinder you can't beat a cheap Chinese one for about £12 off the market. Mine outlasted a Makita and it has been absolutly beasted. I have even used it to stop a van rolling downhill.
I bought it to do one job and throw it. That was over ten years ago!
Vibrates a bit, but still going stong.
I recon it's because they don't have Fridays in China.

A necessary evil is what they are. Noisy diirty and dangerous......I have them in the 3 sizes and also a Stilhlsaw and I conbstantly think of ways to avoid using them until I say to myself.......get the bloody grinder on it!!!!

9" grinder, a great tool for those larger jobs.
I put one down whilst the blade was still spinning (power off) and it hit the ground, twisted and run across my toes.
Fortunately there were very thick leather work shoes. It still went through leaving just the sock between me and the blade.

I ALWAYS wear steel toecaps ever since.

Be Warned, Excellent tool, bloody dangerous when it all goes wrong.
Get Full face Shield (Sparks and exploding discs) Eyes and faces are very soft targets, DONT RISK Them
Steel Toecaps, (see above)
Leather gauntlets / welders gloves (Would take a finger off in a flash of the eyelid)

Even consider the 4.5" ones as a hazard.
I buy the cheapo 4.5" ones, good value for money.

I use 1mm Slotting discs in the small grinder. Gives a nice neat cut, less sparks and less waste, and less heat.
1mm discs do wear quickly, but worth the cost.

Please think Safety First.

Yep, smelly dirty horrid things, avoid at all costs and use something accurate.

They are great for hacking up old cars and scrap iron but that's about it!!!


David Jenkins - 31/5/06 at 08:10 AM

Don't know what all the fuss is about - I can mark out and hacksaw a bit of 25mm square tube in the time it takes to get the grinder out, plug it in, get the safety gear on, etc. etc.

I can also hacksaw at 11:00pm in my garage, without upsetting the neighbours.

An angry grinder is perfect for tidying up welds, etc, and it's hard to think of a better tool for that job, but it really is OTT for cutting bits of tube!

robertst - 31/5/06 at 02:43 PM

imo the hacksaw made about as much noise as the grinder (except the motor whirring), but when i cut some tubes with the hacksaw, that pulsating screech made me realize you make less noise, or at least a shorter durating noise with a grinder than with a hacksaw. fair enough, we're talking about 1.5mm tube which is nothing....


flak monkey - 31/5/06 at 02:46 PM

If it was screeching when you were cutting it with a hacksaw you need to learn how to clamp your work

Cutting straight with a hacksaw is an aquired skill and it takes practice, which many dont posess! Movement from the shoulders not anywhere else, use 2 hands, and let the blade do the work


David Jenkins - 31/5/06 at 02:50 PM

I was about to say the same! If the work is held properly in the vise, and you're cutting nice and steadily close to the vise jaws, then you should make very little noise.

Same goes for filing...

David


robertst - 31/5/06 at 02:53 PM

hmm. good point.. i'll try that..

was holding the tube with my foot.. but still using two hands...


flak monkey - 31/5/06 at 02:55 PM

I wouldnt let you near a grinder

If you dont have the right tools for a job, dont try it. IMO of course.

robertst - 31/5/06 at 02:57 PM

no... for the grinder i use two vices and three clamps... i'm not that reckless!!!

just didnt have the intelligence to use them with a hacksaw


Aboardman - 31/5/06 at 05:15 PM

what is wrong with holding material in one hand and grinder in other hand, done loads of times,


coozer - 1/6/06 at 07:19 PM

Get one of these! £18 off ebay, takes Stihl saw blades. Safe as house. Then just a small 4" grinder is needed for the small jobs. By the way, I hacked my donor about with a 350 petrol Sthil.....

I'd agree if it was sat on a bench rather than a wheelie bin!

Errr, cos you can slip (like I did once) and catch your hand with the grinder (like I did once).

And I can assure you The Tool is as effective at removing the skin from the back of your hand as it is at taking off paint/rust!
It's since then I've insisted on gauntlets whenever grinding!

Or maybe you were joking... sorry!

Cheers,
James


coozer - 2/6/06 at 04:19 PM

The wheely bin was purely out in the light for the photo!

However the bin comes in handy for all kinds of tasks, not least putting rubbish in...


Lawnmower - 14/7/06 at 09:38 PM

My 9 incher let me cut a doorway through a brick wall. Had to keep stopping as Icouldn't see the tool for the dust - still clearing it up now! Very much the most dangerous tool I have used.
