How about a small concept discussion...a sort of design proposition with a number of interesting design problems that we can tackle together and perhaps our discussion can serve as a base for some very interesting buildalongs.
I present to you..
I was joking on another forum about a compact medieval-ish hybrid crossbow with a built in machete, red dot scope...blah blah blah...here it is, only instead of a machete I used a knife.
The idea is simple yet not so simple...I purposely didn't go into detail and presented a sort of basic sketch...as you can see I didn't even give it any specific limb system as to not limit this discussion.
All in all ... Love it, Hate it,...Spill it!
PS: I'm not saying I invented the bicycle here and would love to hear if anyone knows of a similar weapon design.
