Get a bit of dowel, countersink the end. Get some wet-n-dry, form it
into a cone, glue inside dowel.


Imaginitive ;-)

I feel this particular plastic would respond better to a blade than
the wet-n-dry but it's given me a thought re making my own?

If I bored said cone in the end of a bit of ally rod then cut a slot
across the end (parallel to one face of the cone) so that I could slip
various grades of grit paper into the side of the 'cone' ...

How about something like this

where the diagonal line is a slot with a bit of tool steel inserted,
with the edge ground like a lathe tool.


Hey, thanks for that Rob ;-)

Yup, that was the sort of thing I was thinking of *except* that this
'waxy-nylony-plastic' might be a bit particular to cut.

If you have something too aggressive it's likely to snag and just
twist the rod up as you try to turn it and too shallow and it's likely
to skid over the surface ;-(

I dare say with a bit of trial-and-error it would work though
(assuming I can't find something ready made first of course ;-)

Like Nigella's weg eyeliner trimmer. I buy them for 99p from Boots,
peel off the Boots sticker and apply the chrome TRP (Tims Racing
Products) one and sell them for £9.99 [1] to the model car racing
boys! ;-)

Holiday villa here we come! (not)

All the best ..
