Hi Randi,
OK on turning the crossmembers, I see your point. On the ratchet, I do not really envision how that would work. You stick the last pole in, allow it to rotate back a bit and leave it to hold the drum, is that right? But that would mean that when winding it, there should be constant pressure kept on the drum when someone is resetting his pole in a new slot. If it slips, that could be hazardous. I think I will keep the rachet as a safety feature (the only one), it makes life a whole lot easier on the gun crew. And it will be an educational project, so we will be having 11 and 12 year olds firing the piece :errr: :woot:
hock:
The only addaptation then will be using half the amount of torsion cord and replacing the sling with a cup to hold the wet clay ball they just made. We do not really want to sink the target :wink: When the kids have had their fun, we can crank up the amount of rope, install the sling and really let fly :-)
Perhaps they did not even bend the log, just went and picked a tree with a suitable bend, dressing it and halved that, turning it into two logs, just like a shipwright would do.
I read your comment on the sling being placed on the ground loaded. I can see the logic, but what of the previously attached sling? There would have to be a sort of easy release fastening to allow the sling just used to be detached. Could be 3/4 closed hooks, I suppose. This is going to be fun building and testing!!
@agrimensor No need to buy it if you have it there. If you help in the construction you will even get to fire it full power :-) Are there some more pictures of the actual mechanisms, this is a bit too general for me. And I am not very fond of a triggermechanisme which needs operating by standing next to a full cocked torsion arm with a hammer. Need to re-think that one, as I prefer a trigger that works when yanking a cord.
