I was initially taught to use Behlens Woodturner Finish for all of my pens. However here is a summary I put in another on-line forum a while back of an experiment I did a year ago or so. I have not gone back to Behlens since reaching my conclusion (I still use Behlens for non-pen applications though). I find CA to be dramatically more durable for pens then the Behlens.
Experiment
--------------------------------------------------------------------------------
I've been using the Behlens mostly because that was what Woodcraft suggested. This weekend, as an experiment, I did the full sealer, BLO/CA, Renaissance wax top-coat finish route. Observations in comparison to a cocabolla cigar pen with Behlens:
- The BLO/CA approach really didn't take much more time then the Behlens
- The BLO/CA approach is markedly shinier
- The BLO/CA approach fills in the wood pores better
- The BLO/CA approach feels better (that might also be Renaissance versus carnuaba wax differences)
Bottom line, while both approachs work, I expect to go the CA/BLO route for pens in the future and save the Behlens for other turning projects that are less hands-on then pens.
