papertuned
Ok, I finally managed to papertune my Tomkat, well sort off.
I placed my target on a shelf in the storageroom and ducktaped the doorway with paper.
I have offset arrows and straight fletchedones, the bow is now tuned with straight arrows but I tried all afternoon with the offset arrows and kept having irratic flights.
I twiddled with the nocks and the rest and at different distances, 2m and 4m.
Any clues to what's causin' this ???
Most impacts gave me a slightly high left tear.

RE: papertuned
Seriously F ,i tried papertuning my bow and i was getting a right tear . I adjusted and still the same , i adjusted more and still the same . Could i have the Wrong spine shaft ?
I've read you should not always go by papertuning , but this has really bugged me even though my arrows go into target straight [:@].
I'm even getting 5"groups at 45 yds , which i feel is pretty damn good .

RE: papertuned
If you've got good flight with the straight fletch and not with the offset the only culprit that it could be is fletching contact but aren't you shooting a bisquit? If so I'm really stumped. Otherwise get some spray on powder and coat your rest with it then shoot the offsets and see where they're hitting.

RE: papertuned
Rob,
I just put one of my arrows through the Whiskerbiscuit and upon hitting the hairs my vanes are pushed against the black stiffer hairs because of the twisting motion.
I moved my nocks so the vanes only go through and touch the brown softer hairs.
I'll shoot some tomorrow at the practice range, see what happens.
thx

RE: papertuned
Sounds like a fletching clearance problem. Whiskerbiscuits can produce drag and interference, just look at it. Ditch the biscuit and get a good drop away restif you want cleaner more consistant flight. The whiskers wear over time, it is not a consistant rest. It is good enough for hunting in most situations. Biscuits have good points but tuning and accuracy over time it can vary. Offset vanes will contact more whiskers than straight fletch so it may tune differently.
