Interesting thought. I guess that the guard arrangements are
different as well

Pick up a cheap model and use it for cutting disc,grinding disc,thats
what I've done with this Taiwan effort.

I've got a basic compound mitre wood saw from B&Q which I think is down to
about 30 quid these days and don't use because I've got a sliding one with
a bigger blade. Wonder if there's a metal cutting disc that would fit? The
speed isn't a million miles away from an angle grinder - certainly no
faster.

Though my current 330mm chopsaw blade has gone through 20 slices of 50 x
3 square box, dozens of bits of 50x5 flat and 50x50x3 and x5 angle and
is still not fully through.


Is that an abrasive or a diamond disc?


Abrasive.

That's pretty good going for an abrasive. What brand of disc is it?

Dunno - hang on, I'll wander down the garden and look.

Only a tiny shred of label left. Had a blue painted core.

The wood cutter on this Taiwan effort was 210mm the nearest metal cutter I
could find was 180mm at Machinemart,but it done the job and I can now cut
steel pipe perfect and at right angles also. :-)

Eventually they do..

To be fair they probably can't quite! ;-)

abrasives are abrasive all the way to the hub, diamond discs usually
only have a cutting edge that is at most 1cm deep and once that is worn
away you are black to a plain steel disc.


Precisely.

Right - I'll give it a try. It's lying unused under the workbench. It was
simply too small for most of the wood cutting I do, but would be fine for
most metal stuff.

Norton possibly? Their diamond stone cutting discs take plenty of
punishment before giving up.

Get down to Lidl pronto - they should still have a few of last week's
angle grinder stand. That and a cut-off disk is a usable way to cut
this sort of stock.

Otherwise (if this is going to be a habit) then the 150ish quid bandsaws
(Sealey, Clarke et al) are dead handy and not too expensive. More use
than a power hacksaw, certainly (I use both, and the Rapidor hacksaw
only ever gets used for 2" thick unobtainium)

Don't get a reciprocating saw. They cut OK, but clamping is a pain. So
the results are poor, the noise is horrendous and the vibration will
shake your fillings out.

No, certainly wasn't a Norton. Was a cheapie from the local trade tool
shop. £3, IIRC.

I am outside the UK this week, so that one's out. Also, the nearest one is
quite some way away. Could order the Axminster one, though.

It isn't going to be a regular thing. I don't do that much metalwork,
although do do some work with plastics for jig making. I can see that the
metal-cutting bandsaw is flexible which would be appealing. However, it's
physically quite large, I guess, and I am not sure that I could justify its
floor space in the workshop. Thought though.

Shouldn't be problems there. I don't have any amalgam ones :-)


The renting a tubing cutter and pipe vice idea quite appeals, assuming it
will cut through the material OK.

Is this angle grinder territory? If so, can anybody suggest a suitable
cutting wheel?

Otherwise, is a more substantial saw like a cutoff saw required?

I've read through this thread looking for someone to answer the
question, that if you cut galvanising how to you re-seal it ? If the
assembly is to be made of coated steel then there it must be required
to be used in a situation where the galvanising is complete - cut it
and rusting will occur.

I want to build a conservatory of galvanised 2" box section steel as
there is a headroom problem using anything else and if I buy it in and
cut it how do I then protect the exposed ends, drill holes, etc.

Buy plain, put it together (the frame, not the whole thing!) then take
it apart, send it to the galvanisers, then put it all back together
again.

Use zinc-rich paint on all the cut surfaces.

Great stuff provided it hasn't sat in stock for a year or two. I had a
dozen tins once which the boss told me to stir. The zinc powder had
settled into the bottom and was thoroughly stuck. Took /ages/.
