Reaming holes in Lexan - gotta be a better way

[klavy69]

I just use these.

I use these also. The one on the far left in the picture is on my bench at all times. For the price and the fact I always have a cordless drill handy they can't be beat.

Ive used a soldering iron to melt straight through the body shell and makes a stronger ring lip around the opening so as not to crack around the body post so quickly.But for perectionists dremel best if dont let it drift from spot puting the hole in.DON

I have a schumacher body reamer, and it works excellent. It sounds to me that there is something the matter with the reamer you purchased. Or, I guess you could be using it wrong. Are you turning it the right way? . -Jeff

Perhaps you are forcing the tool too much creating the cratering effect. Don't forget its not a drill bit and it cuts on a slight twist unlike a boring tool. Slow it down and see if that works for you.

Of course I tried rotating it with little pressure--and it wasn't biting. If it worked as it ought to, it wouldn't have required more pressure. It seems obvious that I ended up with a crappy Dubro reamer. Using a reamer isn't rocket science.

When the lexan gets super thin, like the recesses in a Protech where the wing tube holes are, I use the small tapered dremel bit.

Sorry mate was not implying you had totally no idea, if thats the case then it is the tool you were using
