DOH!!!

Been using factory reamers with no issues until recently. Built a grip with rubberized cork and some burl cork. Nothing I havent used in the past. This time things got hot and the sand paper popped off the reamers. Had this happen on two of them.

Ordered some replacement sand paper strip and fixed them back up. Went at another grip with burnt cork rings and it happened again.

Not doing anything different than before.

Thoughts?

You didn't write if your using the reamers by hand or turning with power. if your turning the reamer under power, you're probably heating it to the point that the adhesive is becoming soft again. if your reaming by hand, I don't have a suggestion, sorry.

Power sorry. Corded drill.

Same one I've always used.

Are these narrow strips of paper adhered on with contact cement or epoxy coated and covered with crystals?

strips or paper with contact cement.

The first reamers were from the factory. Then I repaired those with new paper and CC.

The cause is HEAT...................you are allowing the reamer to get too hot, which softens the contact cement. Slow down and do not let it get hot to the point the cement releases.

The composite corks are tougher to ream then plain cork, which necessitates going slower when using power to turn the reamer

Went pretty slow on the last grip. Will try to curb it more.

Thanks for the feedback!

Adam,
Use a metal - machine shop made reamer - and you will have no issues with it.

if you can drill the handle out to the smallest area where it will sit then you will have less to ream

ream a ( little ) stop let it cool off Then ream again like said it is not regular cork and will take a little more to inlarge the hole

take a look at the flex coat on reaming handles

Most corded drills are not variable speed, so if yours is not, take it easy and don't let it overheat the reamer.

you can also dril out each ring to the smallest size then glue together and ream when dry

Phil,

I have purchased many corded drills over the years, and except for drills that were purchased MANY years ago, they have all been variable speed.

I use three or 4 corded drills to ream cork. I generally use circular files to ream cork - with the drill turning backward.

Even with the files, I generally am turning the files rather slowly - something like 500-1000 rpm.

Thanks for the feedback fellas.

Like winter fishing, I'll go slower!

Also if you're reaming, go with lay of the strip and not against it. This will help prevent it from popping off if you do happen to heat it just a little.
