Receiver
For a little instant gratification I first cut the main receiver of
the blaster out of an 18" length of 1-1/4" insider diameter
PVC tube. This can be easily worked using wood tools. I taped a template
of the receiver to the pipe and drilled out the cooling holes. There
are a lot of them and it is important to take your time to accurate
drill these out for a good result. I have heard others complain that
the PVC chipped easily whilst drilling, however, I had no problems after
putting my bench drill on it's slowest setting. I didn't drill pilot
holes either; I just attacked the tube with a standard 1/4" bit.
I drilled out the corners and ends of both the cocking slot and the
ejection port. I then cut out the remainder using my rotary tool and
then finished the cuts with a file. I also sanded the surface of the
receiver to remove plastic burs resulting from drilling and cutting.
The kit did come with resin nozzle and end cap which I intend to utilize.
I have cut the barrel from 1/2" diameter aluminum stock tubing.
Inner receiver and flash and ejector port details coming soon.
Grip
The grip on the kit I bought was way too small according to my calculations.
I also didn't like the inaccurate piece the kit's designer had come
up with to connect the grip to the receiver. I am, therefore, trying
to sculpt my own grip. The center frame of the grip I cut from scrap
plexi I bought from my local plastics store. I then sandwiched this
between cardboard grips and slathered the whole thing in generous amounts
on Bondo.
I have now to sand this down and then attached textured plastic to
represent the grip's checkering.
Folded Stock
Using my blueprints I cut and bent the two main arms of the stock from
aluminum strip.
Clip & Magazine Housing
Using a plastic "for sale" sign and my template I cut the
parts for the mag housing (the template that came with the kit I felt
was too small). I assembled the box with superglue and then filled and
sanded the seams. I then wrapped a section of the PVC receiver tube
in abrasive paper, mounted it in a vice and sanded the bottom of the
mag housing on this until I had the correct radius curve for the mag
housing to mount snugly on the receiver.
