White Oak backed Ipe, An update and a repair.

[scars]

Ben I have never seen a bow you built that I didn't like. Amazing workmanship. I think you must see it shooting as you build.

[LittleBen]

Thank you all for the kind words.

Looks great man. I always find is funny how shocked people can be when you make a glass lam looking bow from just wood. Killer work. Corners of your limb edges make me nervous from the pics tho. Rather sharp looking.

I just now saw this. That is a sweet lookin bow!

[LittleBen]

Wakolbinger, the belly side is rather sharp yes. I could definately round them more, but I've never had a problem so I don;t worry too much.

The backing is actually very rounded over on the corners. I stained the backing, then rounded the corners, so the edge between the stained back surface and the unstained rounded edge makes a very sharp looking line, but actually it's rounded to about the radius of about 1/8". You're right on though, always round the corners of the backing well. I guess its also safer to round the belly more as well.


Chackworth, glad you approve, I was inspired by a forward handle bow you had posted which was a nice bocote handle. I had never done a forward handle before so I drew a little inspiration from your bow.

A work of Art.

Though I should post an update on this one.

The oak backing served well for maybe 400 shots but eventually started developing a crack across the back of the bottom limb. Still can't believe it didn't just explode.

Anyway, this bow really got me started on tri-lams and I love it so I needed to come up with a fix. Also the draw weight settled in to about 38# after many days of shooting in hot humid Virginia weather. Lastly it was sitting at 1-1.5" of set at rest.

Three goals:
1) make it shoot able again.
2) make it huntable again (50# @ 25")
3) give her back some reflex

I calculated that I would need to add approximately .040" of limb thickness which I determined was too thin for a hickory back to be applied over the oak. I thought about removing the oak backing with heat (TBIII was used) but I was worried about complete delamination.
I finally decided to sinew the thing with 1 good course and add some reflex in the process. I strung the bow backwards into about 2" reflex IIRC, and applied the sinew with hide glue. I also added some water based leather dye into the hide glue to give it a darkened color so I could just leave the sinew with no skins or anything and it'd be semi-camouflaged.

Here are the results ...
She holds a hair of reflex at rest, probably less than 1/2", draws 51-52#@26" and doesn't explode when you draw it so I'm happy. Being as cold as it is, it's not been shot since reworking it, but will be soon. I will chronograph to determine if any arrow speed was gained, or if the added limb mass negates any gains.

 

 

 

 

No assistant, so this is probably 22" draw

Looks good Ben.

Hope your fix is in fact a FIX.

[LittleBen]

Me too. You can see a small fret on the belly there at a know, but it hasn't been progressing.

I can't imagine that sinew letting go, so I'm hopeful.

[Zradix]

Yeah..I noticed that too.

fingers crossed...
