Never mind....I went and dug out my 50 inch Shrew Scout, I thought I would shoot it a bit before I put it up for sale. But now I love it again. Sorry, you can't have it 

Try a different string material and see what you get, I use BCY Mercury on all my bows and I find it an excellent choice and very quiet

Measure 7 1/4" from the back of the sight window at the shelf not the grip this will work for most R&D longbows and some recurves much less will be noisy also try two sets of cat whiskers and tie them on the little knot also helps .

Congratulations on a great hunt, not just a great bowyer and great hunter.  But hell of a man.

I just received some. I am not impressed. It is translucent with very little character. It has streaks. It is not sanded. I would bet you could sand the pattern off. My guess is they found a way to make the streaky BP glass marketable. I will use it on a prototype and probably end up painting it.

Was the circuit connected? If it was, I think you were measuring the voltage drop across the strip, not the voltage the battery charger was putting into it. I am no electrical genius (I am a mechanical engineer...), so we are starting to get to the limits of my knowledge on the details.

For a power supply, this a random selection from Amazon from the search term 'adjustable DC power supply':

As for wire ratings, have a look at this chart:  https://www.powerstream.com/Wire_Size.htm

12ga is rated for 41A continuous when not in a bundle (chassis rating).

make it out of rough sawn cedar

I picked up a 13" VPA riser on their yearly black Friday sale and with short ILF limbs it makes a 54" bow.  I shoot it with medium limbs for a 56" bow. Total cost just over $500 new, but you can also find these used for less. 

I've found that 18.3% of total string length down from the nock point to be optimal positioning for string silencers.  I also use para cord sheath material as string silencers.  Just pull out the white stuff and put three or four 2" pieces at each end.  This works for me with D/R longbows 60-62 inch long with heavy arrows.  YMMV
  

There are several makers of short longbows.  Check the advertisements up top, and the classifieds.
