Hand Adjustable Reamer?

[Boelkowj]

Can anyone recommend a good expandable type reamer (brand name) for aircraft
work? All I need to do is ream out an elongagted hole a few thousands of an
inch but since it is an aft wing attach fitting and the bolt needs to be a
tight fit. I have seen adjustable reamers range from $20 to $60 (5/16-3/8 in
range). What are the differences? This is a one time job but I want to do it
right. I have been told that a straight flutted reamer would probably be too
big by 2-3 thousands as this will be a in field in situ job and alignment is a
problem since need to go thru 3 holes (sandwich plate and tongue) in one
direction. Thank you.

You might consider buying the next larger size straight fluted reamer and
have it resharpened to the exact size you require. Boeing Surplus has them
for $2.00/lb. last I looked.

Try ENCO they have some adjustable reamers cheap along with a lot of other
machine tool stuff from China

Man... I used to use the things on a regular basis when working as an
instrument technician. I haven't touched one since 87 and can't for
the life of me remember the manufacturer.

I'd just get a good machine tool catalog and look up the brand names.
The ones we used were expensive.

They were adjustable by a small strew in the end. One turn was good
for just a few ten thousandths.

I'd like to have a set of them. I'd like to have a full set of reamers
.... and a mill ... and a lathe... and....

Here's a cheap set (mine were made in India) that covers a lot of ground.
Be careful, though; the blades seem to be too hard. I've shattered them in
one of mine. Naturally the most useful size.
