Author Topic: Question on a maple board bow (Read 4035 times)

vtclimber · « **on:** October 19, 2009, 08:56:45 am »

Morning all. I am new to bow making and have been "lurking" on this site for a week or so now. I've been involved in woodworking for some time now and am also into luthery, but have not made a bow since I was young. I picked up a 1x2 maple board and was hoping for around 45-50 lb draw. I ripped the board in half and so I had 2 pieces that were 1x2 by 3/8" thick, and followed a laminate methodology. I also recurved the ends. The resulting draw was far lighter draw than what I had hoped. It currently has no backing and I was wondering if anyone might be aware of a backing material I could use that might add 7-10lbs of draw? That would put me near what I wanted for a target.

Also, I had a question regarding wood selection (again, if this is posted already I apologize). Coming from a cabinet and luthery world I generally go for quartersawn as opposed to flatsawn or plainsawn. Which type of cut do I really want? If I go the way I did when I was young it would be to quarter a tree and then shape the stave from there....Any insight would be greatly appreciated. Thanks!!

I don't quite follow the sequence of ripping a 1x2 in half and getting two 1x2s 3/8 thick??

To be clear, hat are the dimensions currently of you bow? Thickness and width in lower limb and length.

You can easily slap a 1/8 strip of hickory or maple on it and add 15 lb

Hi Dave,

Currently the bow is as follows:

Just over 3/8" thick in the limbs. It is 58" ntn and pulling at about 35lbs at 24". I would like to get it to 45-50 at 28".
The limbs are 1.5" at handle tapering to .5" at tips.

Truefully, I am not sure why I decided to take the 1x2 and split it except that by doing so I would save some lumber. In retrospect, I might have saved about $5.00 lol.

Thanks!

Sorry, to clarify the splitting the board. I took the 1x2 and split it so I then had 2 boards that were 3/8" thick x1 1/2" wide.

Fine. A 1/8 strip should bring it up to around 50 or more

Sweet! Thanks! I'll try that this evening or tomorrow. I'll keep you posted. It is pretty addictive all in all!

If it's pulling 35# @ 24" it should be around 47# @ 28". I usually gain 3-4# per inch on Osage. I've never worked with Maple though.

You are probably close to that weight now at 28,just not sure if a Maple 58 n-n will handle 28 inch draw.

I agree with the above...58" is a little short for a 28" draw, especially when you're looking for 50+lbs.

vtclimber · « **Reply #9 on:** October 19, 2009, 11:46:21 am »

I was wondering if it would make it to 28 or not...I suppose I'll try to back it with 1/8 piece of maple and go from there with a shorter draw. I can deal with a shorter draw if need be.

Out of curiousity, what would be a good length of maple to achieve a 28" draw? I can't really complain too much as it is my first real attempt. I suppose if it doesn't blow apart I can consider it a success lol.

Pappy · « **Reply #10 on:** October 19, 2009, 12:45:50 pm »

I would say at least 64 and I would probably go 66 if I wasn't going to back it. I haven't work with much Maple so maybe someone that has will chime in.

I'm confused. A 1 x 2 is actually 3/4" x 1.5 ". Splitting it would give 3/4" by 3/4". Splitting means you ripped it end to end. Unless by splitting you mean you cut it in half. I don't know what the hack you mean. LOL. Jawge

lol, sorry for any confusion. Yes, a 1x2 is actually 3/4 x 1 1/2. What I did is cut it lengthwise so that I ended up with 2 pieces that were 3/8 x 1 1/2. I guess the correct term would be resaw to make thinner boards...

Right or wrong, the mentality I had was that by doing that and then gluing them up I alternate grain, etc. Not sure if it will work as planned lol, but I figured it was worth a try. I'll try to post some pics either today or tomorrow. Sometimes (most of the time) pics do a better job af telling the story than I do

As far as draw...a lot of people do go shorter than I do, but I really like my 68~72" bows. I draw nearly 30", though, so maybe a couple ches shorter...but I wouldn't go as far down as 64". Just me, though.

I only have access to maple and oak for boards, so I tend to like the maple. I keep my bows at around 64" for my 26" draw, and usually keep the weight at around #45-47. I'd go for 66" just to be on the safe side.
