Got to work on more arrows. Made a jig to trim the end and drill a hole for the nock. I wanted a smaller diameter than my files for the nock so it worked out well. Was able to get the cut started on my bandsaw so it was a quick process to at least get them started and opened up. Got the shafts down to a decent diameter and worked one to get the process down. After barrel tapering it, it was still at 201 grains and even quite narrow at just over 17/64". I toasted it in the oven at 350F for 30min and then it was in the house for about a week. Measuring it now it is 185 grains. I found for this poplar that if I get the shafts to just under 5/16" diameter and then barrel taper them, they're ending up around 210 grains. I could be more aggressive at the tip end and they will still be trimmed a bit. I was intimidated by the process but it hasn't been bad. Good practice before I consider it for the doug fir shafts I got from Surewood.
