Micro Router Bits

Hi All:

This is from a OT question on another forum. (Details of use below.)
The problem is finding a miniature router round over bit (or ogee bit) of
1/16 inch radius or less. Metric sizes would be OK.
A hand molding plane of small size might also work.

The original poster in that other forum found small router bits that fit a
Dremel like hand rotary power tool with an 1/8 inch shank, . A small router
table was built to house a Dremel tool with the bit sticking up. However,
when getting bits for Dremel like tool from a 3rd party, the quality of the
HSS used and the sharpness of the cutting edges leaves LOTS to be desired.

For artistic reasons (and only for artistic reasons), a round over bit is
needed for some woodworking scroll saw fretwork. Stock thickness is
somewhere between 4mm and 6mm. Length and width about hand holding size.
Needle files, Dremel rasp bits, and sanding
don't have the uniform look wanted. I looked for a manual mini-hand plane,
say something a Luthier might use, but no luck. Although, how the
mini-hand plane blade get sharpened, I don't know.

Hand made Scraper blade? I seem to remember Roy Underhill doing a TV show
about making a hand made scraper blade to do beading work. He made the
scraper profile from an old rusty saw blade. I seem to recall it was WAY
too
much work to hand make such a tool. (had to make mini forge to soften blade
metal, cut, and re-harden the steel.)

a small scratch stock is not so hard to make, I use one for 1/8"
roundovers:

knife blades would require grinding to shape, but pieces of saw blade
can be shaped with files.

Surely a UK importer has the 3" x 1/16" high-speed cutoff wheels
that HF imports here. They make quick work of hardened steel.
I used to cut bearing races with them. See examples here:

These things are just TOO handy!

Right, and without those scary dado blades to hurt them, either.
Let's hope for their sake that die grinders haven't been outlawed.

Thanks for the Bosh router bit link.
I will pass it on.

No, that full 360 degree blade gaurd keeps them safe. :)

Dremel makes a 3/32" 1/8 shank bit. #612. that's a bit larger than you
asked for but maybe you can use it?

Patriarch:

Thanks for the idea on Google search, Inlay tools that Luthiers use. I
seem to have gotten a few hits. I will pass the info on.

Oh, and as normal for my own personal experiences lately, Garrett-Wade had
nothing to offer of any use.

Yes, but...
the problem is cutting the scraper down to a width that would make it
useable. I was thinking that the steel of a scraper is like a saw blade. A
hack saw is not going to work too well.

The person in England has very limited tool selection available.

You might be interested in the cutters that the inlay experts make for
their tasks. Michael Fortune and Steve Latta are two names that come to
mind. I'm pretty sure there are others.

The cutter Michael Fortune described in the short presentation I saw was
made from a cabinet scraper. No heat was required.

You may also wish to consider if the Garrett-Wade people have something
that could work for you. It seems there was an assortment of electronics
and/or dental tools available.

Go down to your local woodworking store, buy a scraper, use a needle file to
put a slot in it.

For small scrapers, pallet banding works well. Can be cut to size with heavy
shears, cold chisel, cutoff disk, ect. File to shape.

Thanks for the link. I will pass that link on just in
case.

But, the problem is cutting off a piece of saw blade.
The person in SW England, at best can come up
with a hack saw. I don't think a hack saw will work
too well on an old saw blade.

Bosch makes a 1/16" roundover bit, but it has a 1/4" shank. It's carbide

Yeah, they're still pretty primitive in SW England.
