Douglas Maple(west) with Hard Maple(east) backing. 63" NTN 43#@26". Yew handle piece and fumed Ocean Spray tip overlays. This was a bit of a gamble as the Doug Maple had a lot of knots. It still may collapse, see the knot on the belly in the pictures. I decided to try this design with no recurves. It shot 177fps at 10 gpp. Now I have to make one with recurves.

Beautiful DC, beautiful, and very good speed i think...!
How did you deflex it and is the reflex just glued in? No steam or heat? Is it from a stave or boards?
Beautiful.
Cheers

I like the profile a bunch DC.Very nice work.Very respectable fps numbers too.What kind and what mass weight of string?The knot does look sketchy but so be it.It's filled with thin super glue right?
PS.....Did both the maples seem even hardness wise?
-
Thanks guys, The belly is from a stave. I cut it in half and spliced it together with about 15 degrees of deflex The backing is from a board. I glued in the reflex. I had meant to heat treat the belly before glueup but I forgot.(I'm old) I would have put in a bit more reflex but I was a little chicken because of the knots. FF string, 8 strand, 42 grains with serving. Lots of super glue. I use more superglue now than I did when i was making model boats

Very nice DC. After your flipped tips one you'll have to try a north meets south.

Osage and Arctic Willow? ;D ;D ;D

That's pretty good and it comes from th N W. I like it DC.

That's almost exactly 1 to 1 grains to pounds of draw.I got into the habit of buying super glue in a 3/4 ounce bottle....lol.1 thin and 1 thicker.
My FF strings are usually 60 to 80 grains.6 strands to 9 strands on approximately same length strings.Using 45 to 50 pound bows.

I wonder why your strings are heavier? I weighed it again, wrapped it up nice and tight so there was no tails taking any weight. I got 45 grains this time. Close enough. I use 65 lb test Spectra fishing line for serving about 7" long. FF is FF isn't it?
PS Unless you use an awful lot of wax ;D ;D ;D ;D
-
You sure have come a long way in a short time man!love the profiles,awesome!
-
I do bees wax the heck out of the string.Helps with the twisting making procedure.My string is FF plus from an archery company.7" of serving also though.I shoot self nocked arrows so serving is thicker at nocking area but that wounld'nt add up to that much.
Well each to their own again I say.You still got a nice bow there.I'm sure the next will be even more impressive.
-
That bow looks very snappy to me. Meaning, I get the feeling that when you release the brace it just wants to snap back into it's pre-braced form. Your tiller looks so darn even and balanced. If I'm right about the snappiness, I'll bet that awesome tiller is mostly responsible. :)
I love the name/concept as well Don. I always look forward to seeing what you'll come up with next. :BB
-
DC,
That looks nicely balanced Sir...Nice work
Don
-
Very impressive! Jawge
-
Cool bow Don
-
Thanks a lot. Your opinions mean a lot to me. Makes my day :D :D
-
Really nice bow again! You really make a lot of bows, and nice ones too ;D
-
Thanks Leon, i only post about half of them. Taking pictures ain't my thing :D
-
You're turning out some performers Don. :OK
-
Very nice DC! I think your performance numbers are legit. Good tiller, efficient design, not much excess mass, light FF string = a fast wooden bow.
So is Douglas Maple considered a hard maple?
-
I don't know if it's a hard maple. It's not as hard as Sugar Maple and not as soft as Big Leaf. It does make a good bow on it's own, this one just had to many knots in the wrong spots. I'll do a SG test if I can find an offcut.
-
I was told that if it isn't hard maple/sugar maple then it's soft maple. I have some red drummond maple that seems similar to your description, but I'm reluctant to try it in a bow as it's not a true hard maple.
-
I just read that too. If that's the case then Doug and Vine maples are both soft and both make good bows. I think that any of the small, multi trunked maples would make good bows. Maybe someone else has experience with Red Maple.
-
Doug Maple has an SG of 0.6 as I measured it. Hard maple is .56 to .71 according to the Wood database but that's with a MC of12%. I dried my sample in the oven for 4 hours. Lets just say they are comparable :D
-
There are 128 species of maple. I'm pretty sure that more than just one of those will make a good bow. )W(
-
Yeah upstate, I need to just cut some and try it for myself. If I’m afraid of a failure, I should take up another hobby )F(
-
Why did you dry the sample in the oven DC ? Just curious
-
To do a proper SG test the wood should be dry, 0% moisture content. At least that's what I think.
-
the hard vs soft category is how maple is marketed in commercial grading, It doesn't have much to do with the qualities of some of the non commercial species
