Title: 58" Recurve Build along
Post by: andrianyuga on June 26, 2016, 03:12:00 PM

Hi Everyone..Greeting from Indonesia
Im new in bow building, usually i make low poundage bows, between 30 - 40 lbs..mostly Reflex Deflex bow

In Indonesia so hard to find standard material for making great bow, we must buy online and of course expensive on shipping cost..
So i started with best material we can find here..( i guess ) lol..

This bow actually i build for my wife, because she's normal archer ( RH ) im LH archer...
Started with one limbs per each during the making...
My Goal is 35# @ 28"..
I hope the results is approach my goal

Feel free to comment, advice or anything else....and sorry for my english

Check This Out

I started with 15mm plywood x 3 pieces for the bow form

Make the clamp hole with 3/4" holesaw bit
 (http://i1372.photobucket.com/albums/ag354/Yuga_Andriano/IMG_20160615_135807_zpseljwqf3g.jpg)  

  Preparing the lam  

I prefered Ramin wood ( Gonystylus spp ) for the core, Meranti Batu ( Dark red Meranti ) for the handle and Sumatran Yew ( Taxus Sumatranus ) for the powerlam

The specs are :
- Paralel lam 1,5mm
- Tapered lam 1,5 mm tapered 0,5 mm to the tips
- 40 cm Handle with 0 mm fade out
- powerlam 25,5 cm lenght 0,5 mm thick  tapered to 0 mm to the end ( 5,5 cm passed handle fadeout )
- Standart fiberglass strip ( Not Bo Tuff ) 1,2 mm thickness

Powerlam

 (http://i1372.photobucket.com/albums/ag354/Yuga_Andriano/IMG_20160609_163513_zpsdomrdsxf.jpg)

Im also do a dry run before, and everything looks good..yeaaah!!

Gluing The Lam

Clamping from the fadeout first to make sure no gap between fade ( handle & Powerlam ) with the handle fitted to the pin hole on the form

My Homemade Clamps, 3/4" pvc pipe bolted with 2cm x 8cm pieces of hardwood..not sure to spent a lot of $ to buy more C clamps..lol

Looking good so far. That is a good idea for clamps. A little slow to use, maybe, but they will give even pressure.
Good luck with the build.
Dave.

Here is after clamping the lam..
I use clear masking tape to make sure there is no air bubble between core and fiberglass

at curve im using pvc pipe bolted to pvc pipe...to get extra pressure which cannot do with flat wood

I love the clamps really, they probably work better than c clamps any ways with that large surface area.
Keep it up man thanks for posting!

Let it cure overnight..and removing clamps
in Indonesia we got high temperature and high humidity weather..

30 - 31 Celcius at the day..and 28 -29 C at night
So i think doesn't need a hotbox.. ( IMHO )

You can sand through the glass Butt's and saw dust/CA glue.
round it over real good then put your overlays to make up what you sanded off.
