Years ago, I bought a cheap hand mitre saw. It looks a bit like this one.
https://www.transtools.co.uk/hand-to...itre-saw-550mm

Until recently, it has always cut square and surprisingly accurately.
Then my son borrowed it. Now, the blade twists, and I get an angled cut.
What's he done to it, and is there any point buying a replacement blade
rather than binning it?

If I do bin it, is there any point in buying something similar or are
they all crap?

BTW, I know that lending tools is a stupid thing to do, but I am happy
to support my son in his new venture, even if he doesn't return stuff in
the same condition. And, more to the point, doesn't tell me that he's
broken it subtly.

I'd say its worth a new blade.

I have a similar cheap saw which I don't have space to store set up, and
will admit to having had the occasional learning experience when
reassembling it. So may I ask (a) is the blade flat and straight when
removed from the saw and (b) have you put it back together again with
the parts list at hand to check that all bits are still there, and in
the right place?

those blades twist & bend if pushed too hard. When blunt they need pushing to cut. It might even not be his fault.

Well, the general consensus seems to be to venture £2.50 on a new blade
then.

Snap!
I used my identical one yesterday for the first time after my son
borrowed it. It also produced an angle to the first cut. Tightening the
blade tension was all it took to get things straight again.

Is that actually a "compound" mitre saw.

A compound mitre saw can cut at a range of angles (some preset) with in addition the
blade
itself also tilted at a variety of angles (again some preset) in addition to the normal
90%

The gap in the fence would suggest that that saw can only cut with the blade set
at a standard 90%.

Is the frame tightened up enough?

Fit a new blade they are cheap enough.

Well it's obvious isn't it:-) You let him work with me and I said "don't
****ing break it"


BTW my Dad has asked me if he can "borrow" the drill I bought him for
Christmas......

No, and Silverline don't call it that so it's a mistake by whoever
wrote that description. Silverline do sell a compound mitre saw for a
fiver more than this one.

I took the saw to pieces, straightened the blade in the workmate,
reassembled it carefully but with the teeth facing towards me, rather
than away, then tightened it really well. It works again. I don't know
which of those actions was what was needed. Quite possibly, as you say,
just tightening it.
