Cutting with 4'' angle grinder
Anybody know if a 4" angle grinder in a 'Screwfix' stand will cut thro all the box section ok, or do I need a 9" grinder. Would rather use the 4"
as it's cheaper to buy (as is the stand) and I presume easier to wield when cleaning welds.

4" or 4.5"? Size matters.

115mm, 4.5"
I have used a 115mm grinder almost exculsively to cut my steel tubes and panels.
Well, four exactly.
they were all cheapies - not sure how much longer a non 15 quid one will last.
First one overheated and burnt out.
Second two stuff their gearboxes.
Fourth one going strong, but possibly might be about to throw first gear soon.
I didnt use a stand.
Dont try and cut alu with it as it just burrs terribly and looks shyte. I have a little 7 quid hand nibbler (yes, the jokes have been done...) from
Machine Mart thats pretty good if you are patient and dont have girly hands.
I cut out all the 1 inch steel panels on my tank with it

I got the 9" one and it's spot on. Guess the 4.5" would be ok but for the extra few quid I'd go for the 9" (discs last longer aswell!)

Thought the 9" would be harder to handle for cleaning welds though....

I've just been to the Screwfix website to see how much these things are, but i cannot find them. Anybody got any ideas as to what section they are
under?

If you want a cheap one go to 'Power Tools' and then 'Ferm'. The stand is code number 8985-66.

I'd recommend getting the 4.5" one not the 9. I borrowed one of each off a friend before buying mine and spent awhile trying them. The 9" was far
heavier and more cumbersome than the 4.5" and basically a pain to use.
In my opinion if you're going to be using it for grinding chassis welds then you particularly want something you can easily get into small joints
etc.
Basically I'd recommend the smaller one.

As is usual for me, I'd recommend both. The 9" is the one for the stand (it's difficult getting it in and out so mine stays there) and the small
one for 'hand' use. The little ones are cheap enough and the stand is good value - I expect the whole lot (two grinders and stand) would set you
back less than a ton from Screwfix.
BTW Ferm was mentioned - that's the 9" I have. Gears are a bit noisey but it does the job no problem. I guess it won't last as long as an
'expensive' grinder but then again you could buy 3 cheap ones for the price of a more expensive one.

My old B&D angle grinder was suffering from noisy gears so I had a nose around inside (typical of me - dismantle anything!). The grease was sitting
in a lump at the side of the casing, while the gears went without.
If you can open the gear casing without wrecking it, perhaps you can slap a bit of grease around.

I'm currently on my 2nd £15 Power Devil 4.5" grinder from Argos. The first burnt out cutting through the anti roll bars on the donor. Argos swapped
it without any hassle.
The 2nd is pretty useless as well. The casing gets so hot that it would burn your hand if you didn't have thick gloves on. I'm hoping that it packs
in soon so I can exchange it for a better quality model.

I tried the 41/2" Screwfix angle grinder stand but found it to be poorly made with loose bearings making accurate cutting impossible. Also I got fed
up with mounting and dismounting the angle grinder (and was too mean to buy two.)
I recommend using a decent hacksaw for the chassis steel - it is not at all difficult to cut 16 gauge RHS and accuracy is much improved.

I am using a 4" angle grinder with some cutting discs and it's coping no problem as long as you don't try to force it thru the box section.

I'd go alomg with Dave, I've got the cheap Screwfix angle grinder and cutting stand, broken one of each so far, but replacements with Screwfix no
probs. During the time I was waiting for replacements I carried on with a good quality hacksaw and blades, cutting each side in turn. Really accurate
and not as hard as I thought it would be. Next gonna try the 1mm stainless steel cutting blades on the angle grinder, ment to be mean... Thanks Jon!

I bought a 4.5 from Screwfix but it was the dear one with a bigger handle etc. and when it arrived it was a 5". £39.95 or something like that but it
really works well. I don't think it would fit the stand as I abandoned that because the clamp gets in the way of the grinder when the blade wears
down  , anyway I bought one of their big steel cutters 13" blade and it,s been used everywhere but at £110 it was a bit extravagant

Don't bother with that angle-grinder stand for sale in the screw-fix catalogue, to be quite honest, IT SUCKS!

Chaps,
I thought about these things before I started building, but being disorganised didn't do anything about it.
So I used a hacksaw. Wasn't that hard. I'll bet difference in time between hacksaw and angle grander is negligible.
