Just did it this weekend.
1 PVC pipe (3/4")
a bunch of eyebolts, eyescrews, a couple screw hooks
some caribiners
clothesline
about $20 plus a 8' x 10' tarp
took about 90 minutes to measure, drill holes, assemble, and install in my garage
I can hoist it up to the rafters when not in use
I can store the tarp on the top frame when not in use
taking it up and down takes about 2 minutes from storage to hitting into it
a good grass mat costs a little more (cheap from $20 to REALLY nice in the hundred$)
and that's about it
I like it a lot
garage is a bit cramped for woods and driver but I fit ok
picking out the hitting angle was based solely on fitting my swing in the space available and not hitting anywhere near the light bulbs
wedges are tricky, you need to position the bottom of the tarp so you hit up into it, instead of from in front of it
best to design it so the tarp is relatively loose (gathers the balls gently, no bounce)
corners are designed to pull the top towards me to cup the receiving face a bit
I can swap in or out any tarp, blanket, sheet, whatever in just seconds....
I thought it would be tricky, but after a couple prototypes, I found out that just a hanging tarp supported only at the top does the job perfectly - no need for a side frame or base unless you really are a chronic shanker
but, here in January Minnesota.......I'll need a better garage heater
next step is a ball collection feature I'm designing in my head - big diameter PVC pipe with wide opening cut along the side attached at the bottom grommets, some way to pin the bottom of the tarp, etc etc etc
