Earlier on, I took a break from the orange bands to figure out the size of the charge retainer. These will be cut from card stock, painted olive drab and glued in place over the U.S. ARMY name.
The charge retainers were on the Estes centering ring card sheet.
The centering ring scan on the JimZ website CLICK HERE seemed a little large.
Using the engine tube hole as a guide, I drew a circle .980" in diameter. That's a hair bigger than the BT-50 size at .976" diameter.
The entire scan was reduced until the centering ring circle matched the .980" diameter circle drawn earlier.
The charge retainer height was then 4.687" tall.
Multiply that by .955 (Estes BT-101 dia. to this TLP kit BT-100) and the new charge retainer should be 4.476" tall.
The Estes retainer was traced, copied and reduced to the 4.476" height.
The retainer will be printed on double layered card stock.
I used my rotary punch to make some of the inside cuts easier.
