I've got a metal guide which clamps around and through a hole in
some plastic (guide for a locking bar in a caravan external front
locker).
The plastic is broken and can barely hold the metal part.
The simplest solution seems to be to fit a thin and wide metal
washer to spread the load and allow the remaining plastic bits to
support the broken area. The metal bit is two plates, one with
studs the other with holes, and a spacer in the middle which fits
inside the hole. Not that much free adjustment on the stud/nut but
enough for one washer. Stacking more than one might be an issue.
O.K. - now for the washer (or similar).
I am reluctant to make my own because of the requirement to make a
proper circular hole in a piece of metal - the tolerances are
fairly fine.
Sods law suggests that nobody will make a washer which has the hole
size I require.
Any alternatives?
I assume the standard way of making flat washers is to punch them
out of sheet steel with a suitable sized punch (the wastage must be
quite something) but suitable sized punches plus a press isn't
sounding cheap.
Will post dimensions in a bit; just trawling for alternative
suggestions in case sod's law turns out to be accurate.
You should be able to make a nice round hole in thin steel if you
clamp it very firmly between two thicker pieces of steel and drill
through the lot. I reckon you could even do it with two pieces of
hardwood.
Any chance of a photograph? I mean of the problem, not of yourself,
although that would be OK as well if it pleases you.

Depends which bits.
Drill bits, of course.
My (possibly wrong) starting assumption was that the hole was too big
for any of my drill bits.
Busy with other stuff for a bit, and very reluctant to open the
locker again in case I can't close the bugger.
Will post a picture and dimensions in a while.
Dimensions:
Hole - 30.92 mm (also size of spacer)
Plate external diameter - 33.85mm
Thickness of all 3 metal parts - about 1.21mm
Just about to try and load some pictures onto the FAQ.

Apologies for the grungy links. I'm sure that there is a better, faster
and easier way of doing things but I'm still floundering my way around
the site.
My current thinking is that if I can replicate the spacer in a broader
piece of metal approximately 1 mm - 1.25 mm thick then this should do
the trick. The holes can be slightly larger because a snug fit isn't
required and the plate (not washer) can be a reasonably random shape as
long as it just covers the flat bits.
If I make it large enough then it could form a back support when I try
and fix the plastic back together. Which will be the next problem as it
has no doubt stretched and distorted whilst breaking. I assume
fibreglass may be the way to go, or car body filler.
Anyway, does this seem like a reasonable plan?
