I'VE CUT LOTS and built lots of HICKORY BOWS my favoret white wood by far. I DO CUT IN THE WINTERT I can't say it matters just my down time from buck hunting before gobber season. I'd surpose it be more moisture (sap) cut in the summer take longer to season. Take the bark off as soon as posable. And seal the whole bow I use white glue or spray poly,varfane, spay paint JUST ABOUT ANYTHING I HAVE. You really don't have to have the stave completely sealed just slow down the moisture loss. just slowing down the moisture lose will stop it from wind checking. But I seal completly but have just used spray paint a few times.
As far as seasoning I leave mine at least a year or 2. sealed out of the wether I had personal staves I've had for 9,10 years before I got around to useing it. But 6 months in a warm place is ok I surpose. Build a hot box. Use a low wattage bulbs you can get. But don't heat up hot fase it will make your staves brittle.
I use''ly cut and split way more than I have time to take the bark off. So here as soon as I cut it I spary it with pestaside IF I'M LEAVEING THE BARK ON. Here we have wood boarers bad and they love white woods. Osage you can get awy with them. White woods will rise up a splinter every time. The won't eat live woods but start on dead woods as soon as in starts it's dead. NOT SURE BUT THEY MUST ALL READY LAY EGGS IN THE BARK WHILE ALIVE.
I reflex my staves now so I don't have to use heat later to do so. So the greener, sooner this is done the easer they are to do. I also cut my staves 80 inchs. Longer beens easyer also. I cut to lenth later went I sell it or use it.
I just cut and split 3 smooth bark 18, 20 inch logs and a 24,25 inch shag bark HICKORY this winter . I got 21 staves and a few belly staves just from it (shag bark). Sled and wadges are killer. I quartered and took to the barn and split a quarter on my own time.I got to find more helpers. My son BRIER 13 BUT DONE IN 1/2 HOUR.
