As mentioned in a previous post, I acquired a Trapmaster 1100 in Fall 2015.

Being restricted to indoor shooting, I am not too keen to use it as a shotgun in the house. I also received a box of the original plastic shells loaded with small lead BB
and I plan to keep them intact in case I would resell it later.

After checking the box, I saw that most of them were in good shape but discovered a few cracked shells still having their content inside. I am not sure if they were
overfilled or just getting old. This meant that the couple of spare empty plastic shells that I was re-using over and over to shoot my wooden projectiles might have limited survival.

After finding some info on the internet and taking some dimensions on the existing shells, I asked a friend to make me a few in brass. They fit very well in the Trapmaster
and I know that they will survive for a long time.

I discovered that the 3/8" wood dowels that I used for my projectiles vary in size depending of the stores where they are bought. The variation goes from .365” to .385”.
I measured the barrel and I got a reading of .385” so all the dowel pieces can be shot through the gun with varying degree of tightness.

BRASS SHELL AND PROJECTILE EXAMPLES

My friend made the test shells on a lathe. I don't have the skills for lathe work but I can machine on a CNC mill and I wanted to see if the shells bore diameters could be
standardized to existing drill sizes.

TRAPMASTER SHELL DRAWING

Before anybody ask, I must say that I can occasionally run the equipment for personal use but cannot be involved in any kind of production, so my intent is to make my
information available to anybody who wants it for their own personal use. I will show the process and, since each text file is a bit long, the programs will be listed in
several entries following this post. That way it should also be easier to find the beginning and the end of a file than if they were included in the main post. It should be noted
that the G-Code has been generated for a Fanuc 6M Matsuura CNC mill, but I suppose it could be edited to be adapted to another machine.

The overall length of the shell is .780" meaning that a standard .75" plate won't work, so I found a piece of scrap aluminum bar measuring 1" by .840" thick and several inches long.
This became the basis for my project.

The plan was to mill five shells in one shot. This required two settings and a little bit of manual work but this is the result of both SETUPS, along with a completed set of shells.
The ones still attached have a bore of .377” and the ones on the table are .386”. My bar was long enough for two sets of five.

SETUP 2 - RESULT

I have a picture showing the first setting on the threaded block that we are using on our CNC mill.

CNC BLOCK
Image

As it is a specific arrangement for us, I made a standardized version (Universal) that could be adapted by anybody. In my case I was working in a global environment and my G-Code
was based on our CNC coordinate system. To make it “universal”, I re-made my CAM files using the coordinate system of the part as it would make it a lot easier to adapt it to
different machines. Furthermore the code would be easier to modify too. Also to make it “universal”, the jig is intended to be placed into a vise and the cavity is used to reset
the part “zero” if the jig is removed and re-installed at another time.

It seems that an aluminum bar of 1" by 1.75" can be available as stock. This is the stock selected for the version I will describe. A piece of that bar will be used for a jig and the
balance will be cut in half (possibly on a band saw if it can cut straight). The nominal stock “cut in half” would now be 1" by .875". The actual stock required for the job will be
1" by .800 so there is a bit of allowance (.075”) for the saw cut.

JIG
Image

Image

The length to be ordered would depend on how many shells are made. The first set on a bar will use 5.375” of the bar (same as the jig) but the subsequent one could be a
bit shorter as the hole, left by the previous machining and which is still on the balance of the stock, can be attached to the jig and only the second one needs to be
drilled and counterbored.


SETUP 1
Image

Image



Image

Basically setup 1 goes from the business end of the shell to under the rim. At this point the machined bar is flipped lengthwise and reattached to the jig.
It is only when I looked at my “setup 2” drawing that I realized that the cavity provided to reset the part “zero” might be a problem. It seems that the
middle shell is not supported but the milling of the final cut with tabs might still work as I started it on that shell first.
This means that it has the full support of the thin uncut sheet around all the rims. Nevertheless, because I didn’t actually machined the shells with this
“universal” version, I decided to redesign another jig that will have the reference surfaces (for setting the “zero”) located on the sides instead of the floor
of the groove. This will be shown after the pictures for setup 2.

SETUP 2
Image



Image



Image



Image



Image

As mentioned earlier in the post, following is the re-designed version of the jig. It is still intended to be held in a vise and the machined flats on 4 sides are the
references to set the part “zero”. In my first version of the jig, I forgot to provide a way to clamp the bar in the groove for the drilling operations so, to correct
the oversight, I have added 4 threaded holes in this second version.

MODIFIED JIG
Image


Image

The text of the G-code for CNC milling will be found in the next entries.
There will be one for the ORIGINAL JIG, the MODIFIED JIG, the SETUP 1 PREP (DRILLING & COUNTERBORES),
the SETUP 1 – MACHINING (SURFACING, DRILLING AND MILLING) .386” BORE,
the patch for SETUP 1 - .377” BORE and the SETUP 2.

There is a title in each but the program text is from the % at the beginning to the % at the end.

Enjoy!

Um?
Why are you milling when you are turning something round?

I have made .45-140 Winchester cartridges before out of solid brass on a Haas CNC Lathe. Can't imagine being that different?

Hi rrdstar!

I know that it looks counterintuitive but as I mentioned in my post I don't have the skills to work on a lathe but I am using the CNC mill very often.

I didn't want to be dependant on other peoples if I could do it myself with what I know.

If the info can be useful to somebody else it is fine, otherwise it will eventually disappear anyway.

There is also the drawing of a single shell in my post, so for somebody handy on a lathe it shouldn't be a big deal to make one from it.

I missed that somewhere Pete that you didn't have lathe access!

Carry-on! I need programming experience and work never gave me the opportunity!

Nice work, but that's a lathe part... Time to setup a CNC lathe.

Great project Pete but did you know the Trapmaster shells are still being made by Joe Robinson
http://phoxxmfg.weebly.com/ He will ship the empty shells and wads to Canada.
I'm also looking into getting a bunch of 3/8 plastic balls for indoor shooting. http://www.usplastic.com/catalog/item.a ... &catid=804

Hi Derek!

Unfortunately I don't see a CNC lathe in the near future but who knows!!!

Hi badshot!

Thanks for the info.

I am not looking for the regular shotshells as I already received a box with the gun. I would not want to have the small lead BBs all over the place indoor. That is the reason I am shooting wood slugs.

On the other hand the other link is interesting. Plastic balls in .38 would probably be a good fit. Any idea how much it would cost to get them in Canada?

Last year I ordered a kit of metric o-rings from the U.S. and my $30 purchase turned out to be closer to $100 after shipping, brokerage and duty. It was not a fun experience.

There is another option that I am now exploring. I received my cal.38 lead ball mold but I am still waiting for the melter. So in the spring (or earlier if the weather is nice), I am planning to try casting.

Anyway, this is a work in progress but with the aluminum and brass shells that I have, I should be good for a long time.

R-Gun Pete

looks good , no harder to do it like this then on a lathe . may take a lil longer .
have you tried putting round stock in the collet and a stationary cutter ? should be super easy for you .
