This is a mod for DIYPark's Repeating Mini Crossbow based on the 2.2mm version. (I kindly received permission to post this.)
The black parts in the picture are the only modified parts. You will need DIYPark's files to use these.
Here is a link to the original design with the files you will need:
I own many recurve bows and was just curious to see how some tapered recurve limbs would work on this awesome design. The limbs are thicker in the middle so I modified the front piece to house them better - this also adds a lot of strength.
I tested these with some 20lb fishing line and it works great. But PLEASE be very careful as these mods add a fair bit of power.
Thank you DIYPark for the awesome design and allowing me to post this mod for it! :)
