Bow Shooting Machine Project

[RickBarbee]

Got a good start on my bow shooting machine.

Still have to build the rocking bow cradle for the front of it, then dress it up, clean it up, and paint it.

When I'm done, it will be 40" from the bow cradle to the front of the crank.

This will work very well.

I'll update as I make progress.

Homemade hooter-shooter?

Homemade hooter-shooter?

Yes, and I'll probably be building a string stretcher attachment for it also.

Didn't bother with pictures just yet. I'll take some when I get the bow cradle built & attached.

Got the main frame dressed up, finished up my crank handle extension, and installed 100" of 2" wide ratchet strap belt.

The spool is 2" wide on the inside, so the 2" belt is forced to roll up nice & straight.

I've had 200# of tension on it so far with no creep. Perfect !

Great idea, for a few more scientific calculations. Apples to apples comparisons.

A 40-inch bow shooting machine with a crank? Genius! I can't wait to see the finished product and hear about its effectiveness. build now gg

[RickBarbee]

I'm a half pot of coffee into my shooting machine build.

Had to swap the rails to do the cradle extension, and maintain the inside width I want, which is 8 inches.

Found enough material to build the extension, but I'm out of bolts. Going to town in a bit to get bolts, but it'll be this afternoon before I can go.

In the mean time, I'll get the extension cut, drilled, and dressed up.

I'm making it all bolt together, so I can take it apart for storage when not using.

Sounds like my projects, fortunately Lowes is only 10min away.

I used to rate task time needed by number of beers. Now it's cups of coffee or glasses of tea.
getting older changes things

[Wudstix]

Getting older is better than not!

The release mechanism will be the most interesting part of the build. I suppose that you could cheat and buy a compound bow release and tie a string to the trigger.

You could make a quick release trigger like MythBusters used to use on their projects. I saved a pattern one time, but haven't made it yet.

Made some good progress on the machine today.

Have it built to adjust to lengths for both bow shooting, and string stretching. Max travel distance is 72"

Going to have to double up on the crank strap to keep it from stretching so much.

Got started on the clamp for my riser cradle before I quit for the night.
