It is bound in the paper tube, I hand pres lightly then do a final tamp with a hammer and machined pressing mandrel, few taps safely compresses it
down solidly (Holding the mandrel remotely so fingers are not over it), no binders. You must use at minimum 2 layers of paper on the side to
facilitate safe ejection
It is carefully cleaned between each operation to remove any lose primary from every part of it!
it is quite safe, even if it goes off the mandrel will be shot away with moderate force and you get confetti (Risk goes up as less paper is used) mind
you I have yet to ever have it go off on me (Know what your primaries do, test test and test some more befor doing any thing with them)
An Arbour press is better but yet to get one, it is all so much safer with a proper press as one operation has much lower risk of one going off then
multiple pressing operations.
So first press all your base charges, then press your primary pellets, then when ready those are pressed over the base charge and continue down the
line
tools needed to make such a thing?, 2 drill bits, A drill press, 2 quality nails, a file, a drill, patience, and a fairly accurate means to measure.
Drill the guide hole as to accommodate the nails shaft that allows smooth movement, in the drill file down the head to a tight fit inside your chosen
tube id, and find a matching drill bit. make a means to limit the depth of the drill bore for this larger diameter, and make a second drill hole.
Smooth out all edges high grit count sand paper does this nicely. File a matching nail to the ID of the paper carrier shell and don (Again ensure this
is nicely smoothed as well sharp edges are risks.
Brass is the best body material due to non sparking nature and is self lubricating to a degree but steel can be used, just implement more
precautionary measures.
