Angle grinder for cutting wood

Novice has small angle grinder (takes discs 115 mm with central hole
diameter 22mm). The discs i've already got for it are for grinding tiles and
metal.

Having knocked down a very old cedar garden shed, I want to cut up all the
wood. I'm wondering if i buy one of the diamond discs available for it,
whether that would be reasonably ok for cutting wood with? I cannot find
any discs that are said to be specifially for wood for this type of angle
grinder.

Some of the shed cladding wood is very thin (with nails all over the place)
so i think the usual circular saw for wood would be a bit too hefty and
vigourous on this thin wood of the shed. Grateful for any suggestions on
the best type of circular disc to go for. Thanks.

No. A grinder will more likely start the wood on fire than cut it. There is
good reason you don't find wood "blades" for an angle grinder. It's
absolutely the wrong tool for the job.

A circular saw will work fine. Be careful with nails, though. A circular saw
will cut them (as long as you don't care about the blade) but it might throw
them too. Wear *lots* of protection. A "Sawsall" (reciprocating saw) is a
better tool for the job, though.

Diamond blade plus angle grinder on a treet stump killed someone
recently (kickback into neck). Suicidal.

You can use a cheap jigsaw with wood ripping blade if you cut them
over a table. Very quick unless stuff is >2in thick.
You can use a reciprocating saw - like a normal handsaw but two blades
driven like hedge trimmer blades, but they cost somewhat more (better
for chopping thro old studwork).

I would not suggest even a handheld circular because of the risk - you
are working "sloppy-fast" which could result in kickback or accidents.
The jigsaw would probably be best for thin cladding (shiplap etc), a
lot quicker than you realise.

The best "circular disc" is the one on your "circular saw". It was
mentioned about using the right tool for the job.

Got a sharp axe, matches maybe?

A wood cutting plade for an angle grinder is available. I is a disk
with chainsaw teeth on it. Think it is used for carving. Definitly not
what you want.

The OP hasn't said what he intends to do with the cut wood. If it's
for a wood burner reasonably uniform size and few splinters is
desirable. Sawing would be the best, I used my table saw (and an old
blade) to cut down the shiplap from our shed refurbishment. That was
for the open fire.

If it's just to make managable for a bonfire, the quickest will be
snapping though over ones knee will probably end up with a bruised
knee fairly quickly. Much better to have a block on the ground a few
inches high and tough pair of boots and use your weight or a stomp to
break it up. I reckon that will be faster than a jigsaw and you still
have the problem of holding the timber.

Sounds scary and dangerous. I would not recommend it. But there is a carving
disc for the mini grinder.

http://www.woodcraft.com/Product/200...rking-Kit.aspx

The capacity for this thing to grab things and throw them into your body is
probably infinite. The only way I would use anything like this if the
material was locked down into a big, secure vise. I would also wear gloves,
face protection and heavy clothing.

In some ways this is like cutting small limbs with a chain saw. The saw
grabs anything that is not solidly secured and throws it. And a certain
percentage of the time it hits you. And it hurts.

The number one rule of cutting anything small like this is to secure the
stock before cutting it. Any movement of the stock can be dangerous.

I think there are 2 types...
- Alligator saw - double blades like a hedge trimmer
- Demolition saw - single blade that just pumps away

Unsure which is cheaper, but more search strings :-)

Alligator saws are more useful for general cutting.
Demolition saws, well they are certainly good at that.

I have a very cheap Wilkinson's 'Swallow' jigsaw which came with a good
selection of blades. After making up maybe 20' of fence going up a steep
slope, from old rescued fence boards of all different lengths, I was amazed
at how easy it was to put a nice profile right along the top using one of
the longer coarsish blades. Should be fine for your shed.

I also did almost buy a reciprocating saw in either Aldi of Lidl when they
were going v cheap last year. At the time though, I thought I'd always be
fit enough to use hand saws...

I saw some discs in Alsford Timber the other day that were available in
9" and 12" (might have been a 4-odd inch too) that were advertised for
wood, especially tree roots. They had some almighty lumps (1/8-1/4") of
abrasive (maybe carbide) suck on the side. Looked bloody viscous - sadly
I can't remember the name.

A google for angle grinder and tree roots might turn up something... Or
ring Alsfords in Hastings (assuming you're in the UK) and ask them what
those bastard evil discs on the front counter in the display stand are
called...
