So, Cantrip has to dog-sit this weekend. Cantrip hates to pick up dog-slobbered balls. Cantrip hates germs you see. And this dog will hound anyone to play ball and will even play ball instead of eating.

So Cantrip created a catapult out of PVC pipe, pipe fittings, a paint bucket, zip ties and bungee cords:



Cantrip saw videos of this design on the internets. Used the following materials from Lowe's:

4 pieces of schedule 40 PVC pipe, 3/4 inch by 5 feet.
6 90 degree slip elbows, 3/4 inch.
2 slip T fittings, 3/4 inch.
1 slip T fitting, 1 inch to 3/4 inch - swivel arm.
1 slip 4-way fitting "cross" 3/4 inch - under bucket.
1 plastic bucket from cleaning section
1 slip endcap, for end of launching arm.
8 zip ties to secure bucket to launch arm w drilled holes.
6 bungee cords.
1 can of purple PVC glue, sets in 15 seconds.

The flowerpots were an afterthought as the contraption needed to be weighed down.

Here's a vid of this thing in action. Will launch all his balls and fetch toys. Notice Cantrip does not touch the slobbered ball:

So you are trying to tell me that you don't have leftover latex gloves from past sexual pleasures you could not wear to touch dog slobbered balls?

Cool contraption though.

Cantrip likes man-slobbered balls, though.

My germ creed prevents me from partaking of sloppy seconds.

Update:

So I grabbed a beer and decided if this dog wanted to play so badly, we were gonna play til he bled. Little did I know that an hour later the stupid dog would be bleeding.

You see, his play area is that concrete area in the back yard. If you leave him anywhere else, he digs holes.

All that running around made one of his paws a little raw. So there were blood stamped paw prints all over his staging area - not too much, and not enough for him to stop, but there had to have been a small cut somewhere.

Too dark for a pic. Will post later.

Stupid (but extremely happy) dog.

You should be more like Cantrip.

You could always go to your local baseball park at night and just "borrow" a pitcher machine, that way all you gotta do is teach the dog where to put the ball and he can play with himself for hours on end.

So I told you this dog would rather play than eat. He likes this game sooooo much that he will play it until he bleeds:



See all those red spots to the left and to the upper right of the ball? That's blood. He will play until his paws are raw, then stop to lick them until they stop bleeding, then start up again.

If you try to leave, he will stop you by standing in your way with the ball in his mouth, . . . while he bleeds all over you.

Sheesh.

Btw, I used 4 cinder blocks shown in the lower right of pic to weigh down the rig. Fires much better now without the recoil effect.

Poor puppy.

You can nurse his paws back with neosporin and baby socks (we electrical tape the socks to our dog so they stay on her dainty ankles).

Plus, the socks absorb the blood so there isn't as much blood on the concrete.

I think Cantrip is trying to win the title of best PVC building WDFer.
