Project: Battery pack

I recently rediscovered my air rifle and as such have been thinking about how to improve it. I have already made one small addition to keep a small amount of ammunition handy whenever I grab the gun.

When I first bought the gun I also went out and bought a cheap gunlight to use for lamping/ratting at night (I bought a second hand version of this). This search should yield something useful. the particular torch I bought came with a normal torch cap and a momentary remote switch. which was great because I could use it as a nnormal torch when i wasnt out hunting. the only proble is is that it only takes two CR123A batteries which are extremely expensive considering that they only last about 6 hours before the light starts to fade and flicker.

So I hit ebay for a quick shopping spree and after some searching and comparing (every little helps 😉 ) I found these battery holders to be the best value for money. Although you could try this search instead: battery holders.

Because rechargeable AA batteries only put out 1.2 v instead of 1.5 I will have to conduct some prelimiary test on the birghtness of the torch runnign at 4.8v (4×1.2). the chances are that it will work just not be as bright(single battery holders are on the way as I write and I will test at a full 6v too).

The plan is to connect a 4 cell holder and a 1 cell in series, and then test the duration, then as necessary add more of these combos in parallel, until a sensible amount of battery life is reached or the pack gets too heavy.

I you’re interested this is where I get my pellets from as my gun is very fussy about which pellets I force down it…:

The ebay store where I get my pellets from although at the time of posting they seam to be all out. (they shipped 2000 RWS superdomes for around £30 which I thought was pretty good value for money)

After coming back from a quick stroll in the woods with the trusty springer I realised that there has to be a better way to carry pellets while out hunting. So I did a quick google image search which showed two basic ideas first some form of pouch or container for pellet: these have several disadvantages, firstly they rattle unless well padded, and secondly they damage the pellets by rattling. Also this isn’t much better than a pocket.
The other idea was some kind of foam used to hold each pellet separately. This ensured that the pellets cannot rattle and reduced potential for damage to pellets.
Being the neigh on compulsive hoarder that I am I realised that I probably have some suitable foam somewhere in my room. The material I found is a firm black foam used to hold electronics in position in a case (in this case a laser pointer/memory stick/ remote/receiver combo thingy). The foam is about ¾ as high as an rws superdome pellet (available here).

 

 

The idea is to cut a small rectangle from the foam and punch small holes about 1/3 the diameter of the pellet into the foam (a leather punch would work great) but I just used a micro screw driver to punch the 4 sides of the hole out and remove the core of foam. This allows the pellets to be pushed into the foam as well as easily removed with the fingertips.
The holes do not have to line up although it does look neater if it is reasonable regular.
I then used electrical tape to attach this patch of foam to the side of my gun stock. So that now when I go out I always have 44 pellets right where I need them, right next to the breach.

Here is a shot of the final product in its simplicity.
