75x105 fletching offsets
 

Does anyone know the reasoning behind the 4 fletch 75 by 105 degree offsets on the Bitz jig? Never used it before and wondered why it is even there.

Not sure, but is it for flu flu?

Possibly for better clearance on a certain type of rest? Not sure here.

It's for 4 fletch. Some ppl prefer 4 fletch over 3. I sold several doz arrows fletched like this & even tried it a couple times several yrs back, using 4 - 4" fletches, but couldn't see much difference (other than being able to nock arrows either side up) so went back to 3 - 5" or 5.5" for most of my arrows.

Yeah Vic, but there are 2 different 4-fletch settings--the 90 x 180 degree, and the 75 x 105. The latter looks kinda funky. The 90 x 180 looks like X, and the 75 x 105 looks something like ><. Bound to have been a special purpose for it.

arrows by kelly's web page has a great article referencing just this. Check it out.

Re: Your original question of what the 75X105 is for, it's mostly for guys shooting compounds, releases and lizard tongue rests. They do it to get better fletch clearance with the flatter angle. 150 degrees between fletches vs only 120 degrees between them (3-fletch) or with the 90 degree 4-fletch.

Art, I'm not sure what you mean. The 75X105 is for a four fletched arrow. The 120 degree three fletch would actually have better clearence, no?

RE: 75x105 fletching offsets
 

Nope. You only have 120 degrees between each fletch with a 3-fletch. With two fletches set at 75 degrees, you wind up with an included angle of 150 degrees, top and/or bottom. 30 degrees MORE clearance. Of course that puts the other two fletches with only 30 degrees between them, so that's why they're set perpendicular to the string. If you can't visualize it in your head, I'll borrow the example LBR used above. It's almost exactly the same angles I'm talking about.
