Title: Newb preparring first glass build??
Post by: matts2 on March 16, 2011, 08:43:00 AM
Alright, I decided it's time to go for it and try and glass bow.  I have my form plans laid out and will start building the form probably tonight.  Last night I ordered a hose from Bingham's and also .030 black and clear glass.  The design will be a R/D design probably 68" ntn.  The choices I have for cores are elm, black locust and I will be getting some actionboo from home depot.  My goal is 45-50#, closer to 50#.  The core lams will all be parallel cut as I can't taper anything evenly.  What should I do with the cores at what thicknesses?

Below is the form design I will be making in case that matters.

Binghams uses a reverse taper in their T/D longbow essentially a parallel stack. They have a weight chart in the catalog.
You will likely have to build one to get your weight benchmark with any new form.

I have looked at that chart and been conversing with another member here.  I am working on a sled tonight so I can make tapered lams in my planer.  I started on the form as well.  

For the bow, I will be going down to a 64" ntn per suggestions for this type of bow.  Also putting a total of 3 degree taper.

PV, I read where Bingham's mentioned reverse taper.  I am not sure what that is referring to.

Matt this is probably a stupid question but how do you make a sled for your planer to taper with??

D.
I was told to mount your new sled that will have a taper planed on it on top of a parallel sled.  Prop one end up at your desired pitch and run it.  I haven't tried it yet and I will probably end up making it more complicated.  But sounds easy enough.
