I wouldn't say "a lot of us" are Hill style bowyers or hunters, or have tons of Hill style bows. I see more 3-piece bows here than almost anything. Then I see one-piece Trilam builders and R/D builders. Very few one-piece recurve builders either.

"please chime in and give me some actual specs to work"

I think I've been dissed

What makes you say that Flem?

Guys so many of you are hill style Longbow hunters and have tonnes of hill style bows ....please chime in and give me some actual specs to work with or does everyone who aspires to make a hill bow for themself need to experiment and reinvent the wheel?

You will probably end up doing some of your own experimentation, but I have extrapolated a stack from my own builds to the specifications that you talked about.

So: Flat form, 12" riser, 66" NTN, .005 total taper, 1.125" at the fades, 7/16" at the nocks, Straight side taper from 2" from the fades to the nocks, Tip wedge extends 5 3/8" into limb from nocks.

Using this formula, a .530 stack should yield a 45# bow at 28" draw AMO.

Also suggest at least 22% of the stack be glass with more glass on the belly than the back. Take this suggestion with a grain of salt because it's more my opinion than anything.

I'm trying to attach a lam stack calculator in case you don't already have it.

I may not work, so far I have only attached pictures.

A bit different than what Longcruise suggested, but here's what I would do:

14" riser, straight form, 0.005 total taper (1 - 0.001 taper and 2 - 0.002 taper and 1 parallel lam), 0.050 glass, total stack of 0.490, limb width = 1.125" from the center out 12" then taper to 0.5" at nocks, no tip wedges (just because I don't feel like messing with them).

As has said before, we all have our own take on a "Hill" style bow. Make what you like and modify as you like. My style has evolved through time.

Longcruise thank you for your reply I appreciate it, could you please tell me the tip wedge butt thickness and if the stack you gave me is for the butt or fade.
I already have a stack calculater which I downloaded sometime ago but thanks anyway...
Thanks & Regards,Dan.

Danjoseph · « **Reply #47 on:** October 26, 2020, 02:00:32 AM »

Thanks Jsweka I appreciate it...
Do you start your side taper 12 out from riser center? If so is it because you get too much bend nearer the fade if you use a straight taper from say like longcruise 2" past fades?
Thanks & regards, Dan.

Hello Flem!! Did you mean like missed?

..
I didn't miss your post thanks for posting...but since I was asking for first hand measurements...I asked again...

Thanks John.

For a guy thats obsessed with one model of bow, from one bowyer, you are soliciting a lot of random information that will not apply. If your goal truly is to fabricate a complete copy of a known bow, the best way forward is to purchase said bow, measure it, then sell it. Or just keep it, because its what you really want.

Stack measured at the butts. Wedge about .030 at the nocks

Yes. That’s just the way I’ve always done it and haven’t done it differently to really see the effects.

Danjoseph · « **Reply #53 on:** October 27, 2020, 12:32:38 AM »

Thanks Longcruise and Jsweka much appreciated...
Flem if I could afford to buy a Wesley why would I want to build a similar bow?? Anyway those following this thread in future will find great info on hill style bows, and as a starting point to build one for themselves...that alone is worth all my asking wouldn't you say?
Thanks & Regards to all Dan.

Stagmitis · « **Reply #54 on:** October 29, 2020, 02:23:13 PM »

Hey DJ have you sttled on a recipe for your build?

Danjoseph · « **Reply #55 on:** October 30, 2020, 08:45:48 AM »

I'm actually more undecided than when I first started this thread

But....
I'm still waiting to order my fiberglass..so I have lots time left to make a final decision....
I know I want a 66" ntn 50 to 55# @28" hill style Longbow for myself and I need to get it right the first time...I don't want a bow that's going to destroy my bow hand neither do I want a whip ended bow....
Regards Dan.

Danjoseph · « **Reply #56 on:** October 31, 2020, 10:59:16 PM »

I forgot to add that my aim is to build it with as deep a core as I can get away with using 0.05" fiberglass ( Bo-tuff UL).

Danjoseph · « **Reply #57 on:** November 01, 2020, 09:40:03 AM »

Stagmitis since you asked I thought I would put down what I have so far....any suggestions you or any of the other generous people on this forum might have are welcome ..

hill style longbow specs...

Plan one
ntn 66
Riser 14
Draw Weight 50 to 55#@28"
Forward Taper 0.005
Fade Width 1.125
nock width 0.4375
stack at butt 0.530
Upper Limb Length 26.875
Lower Limb Length 25.125
Upper Fade Depth 0.499
Lower Fade Depth 0.491
Riser Offset 0.875
Tip Depth 0.365
Glass Percentage Fades 20.20
Glass Percentage Tips 27.39

Plan two
ntn 64
Riser 14
Draw Weight 50 to 55#@28"
Forward Taper 0.005
Fade Width 1.125
nock width 0.4375
stack at butt 0.510
Upper Limb Length 25.875
Lower Limb Length 24.125
UpperFadeDepth 0.479
LowerFadeDepth 0.470
Riser Offset 0.875
Tip Depth 0.350
Glass Percentage Fades 21.07
Glass Percentage Tips 28.60

Taper the fiberglass on back and belly so that the tips are at about .03" thick to reduce fiberglass to wood ratio at the tips to plus/minus 25%

Regards, Dan

Danjoseph · « **Reply #58 on:** November 01, 2020, 10:24:51 AM »

I also added the plan for a 64" since my drawlength is 26.5" or thereabouts....someone suggested that it may perform better at my drawlength.....I'm still open to suggestions..
Regards, Dan

Longcruise · « **Reply #59 on:** November 01, 2020, 03:09:22 PM »

You might reconsider the limb length differential. Hill style bows with a shortened limb are known, but with the precision tapers we use now. I think those older bows with different length limbs are the result of the bowyer piking one limb to correct tiller that was off due to poorly matched lams.

If you want to sand your glass thinner towards the tips, you might want to reduce the proposed 005 taper.
