Terry,
Here is a bow holder i whipped together after a quick trip to the Depot store to purchase a short length of PVC and a cap for the bottom and a T-joint for the recurve holder. Heavy duty zip ties, pre-drilled steel strip that I had laying around froma previous job, pipe insulation I had laying around, can of black spray paint left over.
The straight pipe will only hold an unstrung longbow. The PVC tube has a piece of pipe insulation inside of it and a piece at the bottom, to protect the bow during transport, and to quiet it down as well.
The T type addition that is used for recurves either strung or unstrung will also hold a strung longbow. I simply cut away a third of the "T" joint, and filled the cavity with expqansion foam. I use rubber or bungee type short straps to secure the bow in the holder.
It isn't the prettiest set up, but it is rock solid, pretty lightweight, and very quiet. I drilled holes on the back side of the PVC to allow the heavy duty zip ties through, and put moleskin at the points where contact is made with either the bike rack or the attachment brace at the bottom. Works real well.
***As a word of caution, make sure to do a fit check on the placement of the PVC tube. I had to modify my initial installation a bit because when I first built and installed it, it seemed to work fine, but then with boots on my heel kept hitting the bottom of the tube. Make sure to leave enough clearance.
I have found the front suspension to be nice to have and easier on the body in general. I generally wear in a small backpack, and can strap any extra clothing or whatever to the bike rack.
I am working on an adaptor for a game that I have to allow it to hook to the bike as well. Will post photos of that when I complete it. Hopefully, I can show it being used for it's intended purpose.
Straight shafts,
Chuck
