A couple ready for finishing...
« on: January 01, 2019, 02:00:58 pm »
Two bows one post! Figured a back to back post would be a little annoying for the timeline so I'll just throw two bows in here. Used imgur with the hope it gives better photo quality and size.

So this one was inspired by I believe JNystrom's osage bow from a little back. I was originally gonna go for 75" nock to nock, but after seeing his bow still being considerably overbuilt (by mass) and only at 73" and 140 lbs I thought for my goal weight of plus minus 100 lbs 73" should be practically normal. This one is all heartwood because that's how the stave was presented to me, but I have some bark on osage I harvested my self to do heart wood sapwood ones with once dry. The result is this! Shoots with a lovely almost no handshock for the draw weight. Stats:

-73" ntn -
-1" string follow after shooting
-104# @ 31"
-29.35 oz.
-31 x 28.1mm at the handle
-13mm self tips later to be fitted with 12mm cone cow horn nocks

This one's got nothing on Marc's or Timo on paleoplanet's ERC legends but I managed an Eastern Red Cedar warbow! I've always loved ERC. It's just too beautiful not to try to coax a bow out of and it makes fast bows with low set when it doesn't blow. But I'd be a dirty liar if I said it didn't take me two breaks from the same tree to get this success. *First break happened at the horn tip though and I think may have been my error in how high I cut the nock 22mm rather than a proper tension failure of the wood.  I shot a dozen through it today and it has a kick but nothing I can't handle and a small kick considering the physical length and rather circular tiller. Stats:

-83" ntn
-3/4" string follow after shooting
-105# @ 31"
-32.75 oz.
-45.8 x 36.2mm at handle
-16mm at wood insertion to water buffalo horn tips w/ side nocks

Sorry for how much I write! Enjoy!

  Nice job on those bows! I chuckled out loud when I looked at the erc bow, I had a feeling it would have some big dimensions to it. That is about heaviest ERC I have seen. Another wood you might consider is cherry. They are large dimensions like the ERC but still easily come in within projected mass weights. You can back them with red oak, white oak, ash, maple most anything you like.

 ;D Yeah it's comical to hold for sure. Thank you very much! I agree it's amazing to me that the mass of the two are only 3 oz off. This is a link actually for a hickory backed black cherry I did awhile ago. https://www.instagram.com/p/BnXyr-PHpA4/ It ended up just under 130 @ 31". The dimensions at the handle are more reasonable 39.1 x 29.6mm but the hickory is thick at about 3/16 inch thick. It's 82.5" ntn so in a similar ball park there. I'd love to try a self cherry next!

Also, I apologize if I missed this in TBB. But, how do you alter the mass calculation for bows longer than 76" ntn since that's where the table ends?

   I rarely go over 76" so can't say with any real authority how the mass would be affected at 82". I would tend to think past 72" It might be safe to say dropping a percent every couple of inches would be close. The mass formula is really a rule of thumb I developed not hardline science. I am often surprised at how well it works for me and still use it on all my bows.

Makes sense. Thank you for the explanation.
