Hi all,

Is there a gadget out there that would de-burr / put a 45 deg chamfer
on the end of a range of small diameter rods (say 2-10mm dia)?

Like a hand countersink tool would do for a range of small holes, this
*thing* would for rods?

Like a pencil sharpener but at a greater angle and less aggressive?

All the best ..

Depending on the quantity and their lengths either a drill held in a vice,
or lathe if you have access to one, and a file, but if you have lots to do
it would be quite time consuming! Also the chamfers wouldn't be exactly the
same but this may not matter.

I have a grinding wheel with a drill
sharpening attachment. It is just a
short length of angle iron that holds
the end of the drill at a fixed angle
to the side of the grinding wheel.
It also chamfers the cut ends of rods
quite nicely.

When the rods are too short to hold I
stick them in the electric drill and
spin them against a spinning grinding
wheel (usually for putting points on).
Rough cuts when the spins are in the
opposite directions, face the other
way for finishing cuts.

A lathe...

:-)

Also, put rod in drill chuck and use static grinding disk,

Also use bench grinder and carefully rotate rod ..

On balance, unless hyper accuracy is required, I'd do the latter.

Bench grinders are pretty cheap in the sheds.

A grinding wheel?
But that requires a modicum of skill to get the angle consistent.

Thanks for the thoughts / ideas so far guys but in hindsight I realise
I should have highlited the 'hand tool' direction a bit stronger (I
did say 'like a hand countersink / pencil sharpner' but that was still
a bit loose) ;-(

In this situation the (plastic) rods are 'fixed' (can't easily be
taken to my Myford and aren't 'rod' section all the way down) and only
need a rough chamfer on them, just summat better than a dead square
end, to assist the entry of the rod through a cover as it's placed
over them.

Being a sorta flexible nylony / plastic type material it doesn't take
to being 'filed' as such and sorta ends up all hairy (that can be
removed with some wet-n-dry but not the magic solution I was hoping
for) ;-(

And being only ~ 4mm diameter not an easy size to file / rasp round in
situ anyway?

So it want's to be to the rod, what a hand held countersink (rather
than de-burring tool) would be to the edges of a drilled hole and used
like a chalk on the end of a cue ..(as it portable / adaptable) ;-)

All the best and thanks again ..

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' ...

All the best ..

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.

An inspired answer Frank, I knew I'd seen a stone shaped like that but
couldn't think where. They're still available too:

There even seem to be some electric ones:

When I bought my Spot Welder it came with such a device that fits in
an electric drill and sharpens the copper electrodes to a blunt cone -
so go and spend £400 on a spot welder and you'll get one free !

The message
from "Andrew Mawson" contains
these words:

Cor, when I was a lad we had to do that with a file.

Well that means someone makes them though eh ..?

Any idea what the actuall cutters are in there please Andrew?

Well, I'm not sure how easy it would be to work 'hand held' but the

Yes, an inside-out countersink. They have 5 cutting edges, so that
they run true.

Haven't seen one for sale in years, mine are a mixture of '50s and
pre-war. Dead handy gadgets and I snap them up whenever I see one -
excellent tools when starting with a diestock.
