I recently ordered a new Mohawk and would like to build some arrows for it. Everything ive read tells me to wait till the bow arrives to do so but I have been told by my wife to do so now while we have the funds..
 I tried using Stu's calculator but since my home computer took a big dump awhile back im stuck surfing the net on my phone, and its not working out.
 Im going to order some Surewood shafts. My mohawk will be 50# @ 26" ( I draw 26") I will be using 160 grain heads. 5" shield cut feathers. 29" shaft?
 If anyone could help me out a bit that would be great....

Seeing that the bow uses a fastflight string,you want a 29" arrow and a 160gr head, I would say 65/70 or 70/75. If you cut the arrow shorter, you could use less spine. My .02 cents.

Ask, the bowyer, but I would say 65-70 will be darn close left at 29"s. If you cut the 27.5 you could go to 60-65 most likely. Shawn

Thanks guys I will have to give Vince a call then....

I think Shawn is right on.

Good luck with the new bow and arrows!

Why would you want a 29 inch shaft if your draw is 26 inches.  Most folks who shoot woodies leave about one inch behind the point protruding beyond the back of the bow.  Unless you need the extra length for extra arrow weight, really isn't necessary to have the additional length.

I think something in the 55-60# range would work nicely. Generally, a rule of thumb is to subtract 5# of weight for every inch below 28 inches one draws.  Likewise, one usually adds 5# of draw weight for every inch beyond 28 inches one draws. Your draw length is 26 inches regardless of arrow length so adding spine weight because of increased arrow length is not the way to go.  Though the longer arrow does have the effect of decreasing dynamic spine when shot, it's not a big factor at a 26 inch draw.

On the other hand, one usually adds 5# of weight for a fast flite string, which I assume your bow has, and another 5# for a points over 125 grains, in the 160 grain range.  So, following general rules,we've subtracted 10# of spine and added 10# of spine to the the 50# at 26 you're drawing. Nul sum game to this point.  

If the bow is cut to center rather than 1/8-inch from center you might add another 5# of spine (another rule of thumb).  Finally, on high performance bows (extreme reflex/deflex) it's also a general rule of thumb to add another 5# of spine.  Not knowing whether your bow is cut to center or not, and assuming it's a good performance but not really high performance bow, I'd err of the safe side and add 5#-10# more.  Even if it's not cut to center or high performance,  most bows shoot woods spined a little heavy better than they do woodies spined right at or below bow weight.  Good luck.

I'm pretty new to this tis why I asked for some help. I don't suppose I need a 29" arrow also why I had a ? next to it. Thanks for all the advice.

Mohawks love heavy arrows ( Ive had several) so I think I would leave the arrow 29 in. and would shoot 6065 with the 160 point . They will not be to weak out of your bow due to it being mild reflex deflex and would make for a heavy quiet arrow . BUT check with vince and see what he says , im thinking he will tell you the same as thats what Ive shot from my Hawks 50lbs @ 28 in.
