I recently bought some  # 7 fiberglass arrows. Cut to lenght with a good cut off saw and when I flexed the shaft all 4 split. 1 at the nock end and 3 at the insert end and I didn't flex them much. Did not use any heat installing the incerts. I know these are not micro flites but appear to be almost the same. Just wondering if any of you have had the same thing happen. I still have 20 good shafts and hate not to use them but I'm waiting to see what you guys have to say.

 

 

The only fiberglass shaft I can find that has the #7 on it is a Condor. The spine chart show about the same as Micro-flight. However it does not show ID or OD sizes. It could be that your inserts are just a tad too large in Dia. and are stressing the shaft which then splits. You may want to mic the shafts and inserts. Or if you have a spare insert snad/grind it down slightly.

Ron, the inserts were not tight at all.

I doubt that you have 20 good shafts. save a trip to the ER and use them in the garden.

Doug, IMO the glue in the shaft is dried out from heat. I would trash those shafts before you get hurt.

I believe they are DuraFlight shafts. I'd trash them myself.

tomato stakes maybe

I had a Port Orford Cedar go to "hell in a handbasket" in my left hand. I spent 3 hours in surgery and 4 nights in the hospital on antibiotics. I couldn't imagine what it would cost pulling out glass splinters.I'd dump them,or sell them on ,,,e- ,,no, couldn't do that.;-)

If they split upon flexing, it sounds like the glass/resin caused the problem, probably due to ageing; too brittle to shoot. If any survive, a flex test, they may still break; definitely not worth the risk of injury.

Better safe than sorry. Get rid of them.
