My board bow (build along?)

[Marin]

So my fade work is fine? Bubby, so I'm going to be able to work more on the fades as I thin the limbs down? And ajooter, a roundness in my fades is natural when using a rounded rasp?

[Marin]

Finished rasping the belly taper. I got as close to the line as possible without rasping it off. The belly feels pretty even but looking at it closely I can see some unevenness and it appears to be slightly rounded from my rasping job.  I hope this can be fixed when I floor tiller and do the final tillering.
I do have a question. At this stage I would trap the back but I heard someone say that trapping the back causes the bow to loose 3 lbs. Is this true? Should I still trap the back even though my bow will loose draw weight? However, if I trap the back, can I attempt a higher draw weight?

[DesertDisciple]

Marin, have you had a chance to floor tiller yet? You wouldn't need to trap the back until you are close to done with final tillering. If you absolutely want to make weight then just aim for slightly heavier than you want and trap the back when you within 6-8 inches of your draw length. Then check tiller and shoot it in.

Don't worry about trapping yet. Get her bending.

[Marin]

Haven't had time these past couple of weeks to work on it.
Finally have some time today. I am currently floor tillering the bow.
The bow is bending when I put the one limb on the ground against my foot and bend it towards me but it still feels a little stiff. How do I know what is "enough" floor tillering? By that I mean how do I know when I should stop floor tillering and begin final tillering?

[Marin]

Anyone know if besides Dacron b50 there are other bowstring materials i could use instead? I have some 1000% polyester thread for serving machines so i'm wondering if that could be used, as dacron is polyester?

[loon]

I don't see why not - dacron is polyester. when in doubt just make it thick. even if it's braided it should be fine

Adam Karpowicz mentions using copper wire as a tillering string... anything stiff enough should work. Any natural fiber, or any synthetic fiber other than nylon that's no stretchier than polyester I guess

If your bow is heavy, it will feel very stiff. Even if it's straight, 70lbs feels very stiff for me to string. You probably don't want it to be too easy to bend at floor tiller or you'd end up underweight after tillering. Just don't break it or something.

[Marin]

Well, just got in from floor tillering. I decided to rasp my belly taper line off and now the thing is a bit easier to bend. It still is stiff but I heard that's good so hopefully I didn't remove too much 
I'm including some pics of my limb. If anythings  wrong please tell me.now I am going to cut the nocks, make a long tillering string, and try to figure how I'm going to tiller. In wondering if I should use a tillering device or, to save time, try to use a mirror. Anyone have suggestions?

[Marin]

Here's some pics. The first two is the lb being floor tilllered and the last one is the limb and how it looks from the top view.

[Marin]

Here's a pic of something bad I found. My glued on handle has a gap. I haven't seen it till now and I don't know how it developed. Anybody know what I should do to fix it?

[Marin]

Guys, I was about to use some 100% polyester thread and to test it out I tired to break it with my hands. It broke 
I heard it is the number of strands that controls the strength of bow string. If I use enough strands, could it make a good bow string or should I just not use it at all?

[bubby]

Marin how long is your bow I'll make you a string for it

[loon]

i'm a beginner too and was wondering if it's a good idea to wrap a glued-on handle tightly with strong thread or sinew to prevent it from popping off?

for a tillering long string, that stuff may be okay but it seems like you'd have to make it very thick - it'd be a very poor bowstring

try hanging weights from it until it breaks to find around what the breaking strength of each strand is. make it so the breaking strength is something like 250lbs

Spectra fishing line works. Dyneema,Spiderwire, one of those.

[Marin]

Bubby,
I Sent you a personal message concerning that offer.

[Marin]

I'm about to make tillering gizmo. I think I'll just make one without a pulley (a tillering stick). Does anyone think I should do a different design?
