First of all, I just tried to dial Bitzenburger Machine and Tool. Talk about an unprofessional voicemail! Jeez, you can't even tell you've reached the right number. A quick "leave a message" is all you get! I would have thought a company like this would have a more sophisticated, courteous system in place.
Anyway, what I called them about was the problem I'm having setting up the right-wing clamp to where the cock vane is straight up in line with the string. There are three settings - 120, 90 and 75x105 degrees. I'm using standard three fletches but on the 120 degree setting, there is no "position" that starts the cock vane exactly in line with the string. After applying all three vanes to the shaft, I have to remove the arrow and manually turn the nock about 15 degrees before it is exactly straight up and in line with the string. This is not good when you ruin a single fletching and try to just replace it as there is no position on the nock receiver to reference to. I have to "eyeball' it, which is really no good.
What am I doing wrong??
