I sent him an email the same as when I posted but haven't heard back. Do you have a rabaser? Are you making bands. I found the instructions "makie your own bands" to be slightly flawed. The recommended tubing diameter was off a bit. I am attempting to reverse engineer from the few bands I have but to get anything other than amber tubing I have to buy about 300'. Needless to say that will leave me with a little extra. If I can find other interested in sharing the cost it wouldn't be so bad. You can email me direct at mweckwerth@larkin-grp.com.
