Title: Got lucky on one
Post by: Badger on June 11, 2019, 05:28:22 pm
  I was glueing up an RD yesterday. I normally weight the backing and the belly and grind it down till I am within about 3 or 4 oz of projected mass and then I glue it up. That usually puts me right at floor tiller coming out of the form. This time I went a bit too far and ground it down to within 1 oz of projected mass. I glued it up with tightbond and let it sit in the hot sun for about 3 hours, unwrapped it and gave it 2 more hours. I cleaned it up on the belt sander and put it on the long string. Just by sheer luck no tillering at all and the bow came in at 49.8# after exercising. It lost a total of 2# and took 1/2" total set. I am having a little trouble handling my bows at 50# right now so I had to test it at 26" with a 500 grain arrow. I got 175 and 176 fps. I figure that should put it right at 190 or so when shot for flight. Top limb is a little strong but the bow is asymmetrical by 2 1/2" so it seems to handle the negative tiller pretty well and shoot cleanly. Best one I have had in some time and I blame it mostly on luck

Dang Steve. And I get happy when I can just get an even tiller at first brace, you are getting even tillers at full draw, and at target draw weight. That is absolutely insane. I wish I could learn from you directly.

  Mostly just blind luck, I pretillered the pieces on the belt sander before glue up. Not room for adjustments though when I cut it this close.

You know what they say Badger. Sometimes it's better to be lucky than good. But it's even better to be both. Good job.

I think I had one bow at floor tiller right out of the gate kind of sweet when that happens.
"I am having a little trouble handling my bows at 50#" .I hear ya I'm 63 and pulling anything over 38 is getting to be a strain on the old arms.

Got bit of a Yumi thing going on there. ;D ;D It scares me when I cut it close. I've never been that close but the last few have taken very little tillering after bracing. Sooner or later I'll go to far.

  This one here my main goal was as little set as possible for efficiency. I kept the handle and fade area short 8" as opposed to my usual 12" to 13". I also made it longer at 68" nock to nock, top limb is 2 1/4 " longer ( slight mistake here should have been 1 1/2" but I decided not to cut it down) It stores right at 50# energy which was also my goal.

Congrats on that one!  Sometimes everything just falls right when you know what you're doing!  Looks nice to me!  I'm lucky to not have blown up the second one, yet!

Yp limb is bending a bit too much out of the fades but it seems to be holding up. I should probably shorten the top limb a couple inches and retiller it, might stiffen that area up a little.

Nice.... grip getting shorter, limbs longer... it's on it's way to becoming a ELB  ;D ;)

So nice when that happens! And fast too! Since you did not put much work in and with that length I would cut off that inch from the top and fix the spot next to the handle. Lose a little mass, gain a little speed ;D

Looks great...love the profile of the shorter riser and longer limb... it looks like a 'real' longbow...  :OK

Luck? I don't think so. Skill? You bet. Nice job, Steve. Jawge

Post by: SLIMBOB on June 12, 2019, 06:27:29 am
Yeah I agree with Jawge.  A degree of luck involved, sure.  But it took a keen sense of of how all these things work to get you close enough to get lucky.  Nicely done sir!

I feel your pain on pulling 50 # Steve. I was trying to work up to 70# and pinched a nerve I guess. Now I can get to about 26" and my bow arm just collapse. It sucks when you have equipment that has potential to break records. Oh well I guess the records belong to someone else . Nice bow by the way Steve. Arvin

   Arvin, easy fix for your neck and shoulder. Give me a call. 10 minute fx!

Very nice Steve.  Thanks for sharing. 
That has happened to me a couple times with tri lams, as it's easier to dial in your recipe with those.  I almost felt guilty when it happened....

I quit making my bows asymmetric for the reason you have mentioned.  Something about a negative tiller doesn't sit well with me.

nice one badger, it looks amazing! also whats the difference between a negitive tiller and a positive tiller?

What really surprised me was the (lack of) length of time you let the glue set :o. An eye opener.

  I wouldn't recommend that but on hot summer days I have done that a lot. I actually had it at full draw in less than 8 hours from the time of glue up. If I am real serious about a bow I usually wait a full 24 hours but sometimes I am just bored and looking for something to play with.

I had a pinched nerve last Mojam. It lasted months. However, it did eventually go away. Some of the worst pain I had ever experienced. My blood pressure was so high from pain they gave me all the morphine I asked for. ( I got addicted that stuff at a young age, and I try to not need it, but sometimes you just need help ) 

I'm sorry you are going through that. Try to not let the pain stress you too much, and take it easy. It's my opi in a 26 inch draw can be record breaking as well.... I hope to prove that soon, I hit 200 yards at 26 inch draw last mojam. Build a bow for a 26 inch draw, and you may be surprised at what it can do.

I like this one Steve!  I also like to avoid having to do any filleting on a tiller tree after glue-up because I usually end up with something worse than I started with. Hahaha!  I hope you get 400 yards with this one!

I am also amazed you got away with such a short drying time. Tight bond traps moisture in the bow and it can take awhile for it to work its way out. I guess it depends on the types of wood used. I usually wait a week (bow kept in a warm dry place) after bonding a bow with Tightbond 3.  Maybe tightbond 1 sets up quicker and stronger than tightbond 3.  But Ive had joints easily come apart after sitting in a hot car all day when using tropical like ipe and massaranduba.  I still noticed a high moisture content in the joint when I pulled it apart.
