Project Night Prowler Redeux Pt1
In between coats of body filler, I decided to perform some more mods.
I wanted to try to make a custom checkered aluminum butt plate.
To start I
cut out a piece of 1/4" thick aluminum from some scrap I had laying
around and traced the butt stock onto it
I then
figured the best location for the screws and found the center of my
outline and drilled and countersunk the holes. The screws fit flush and
the Phillips heads will look less traditional than slotted ones (the
factory screws were also Phillips head).
The
original butt plate screws were stripped and someone had used finishing
nails to hold the butt plate on (maybe I should include that in an
update of 7 Signs that an Amateur has worked on your gun)?
I drilled the holes out to 5/16" and plugged them with these dowels and some Elmer's wood glue
I then cut the excess off and sanded the wood smooth
then marked the center line and drilled my two holes, making sure they were as close to centered as possible
Then attached the soon to be butt plate
After much work with the file, it is close
Then some 100 grit emory cloth and it is 99% there, we'll perform the final fit just before paint
I removed
the butt plate and attached it to a piece of wood, I marked the guide
lines for the checkering file, these angles will give us good diamonds
Despite
using a straight edge and being careful, the file would jump its tracks
more often than a New Jersey commuter train. It was next to impossible
to get clean lines.
After
trying several different tactics I gave up on it looking good, I just
put lines on the metal and called it good. Maybe I should have just put straight horizontal likes across the face?
I can tell you this, I will do more research before attempting to checker aluminum again. I am sure there is a technique or trick to making it work.
I decided
to try one more of my "cheap tricks". using a square, straight edge
ruler, some tape and a single line checkering tool I marked out the area
where my left hand cradles the stock
Then I used the single line tracing tool and made a double border
I then installed a small round burr in my Dremel tool
Making dimples and squiggly lines I created gription (grip + traction) for my hand. These are much larger squiggles than what you get with stippling, maybe I should have used a smaller burr?
Stay tuned for part 3
Regarding the checkering of the aluminum, you may want to consider using kerosene as a lubricant. Kerosene the machinist's conventionally accepted lube for aluminum and will keep your file from dragging which may be the root cause for the skipping problem you had. You may have to experiment a little to see ho much works best, i.e. a thin film of the lube, or even have your work-piece slightly submerged in the kerosene so that the file glides smoothly. I'm an avid follower of your posts so keep up the great work!
ReplyDeleteThanks! I knew there had to be a trick to it. I'll give Kerosene a try next time
