I didn't want to just use roll pins in place of spiral pins, they're a risk. So, I inserted (hammered) a 5/32" roll pin into a 1/4" roll pin which virtually doubles the thinkness of the pins which brings their shear strength closer to that of the spiral pin. Also, since both pins will still compress, I had NO trouble at all driving these "modified" pins into the 1/4" holes in my CRS driveshaft. I feel safer using these than a single roll pin.

Been there....Done that. It doesn't hold up. You need to use a coil/spirol pin. A coil/spirol pin will absorb shock and vibration. A roll pin...even one doubled up will not absorb shock and vibration and will not be as strong and will fail faster.
The few pennies you think your saving will cast you more in the long run. Hydraulic pumps has pulses and vibrations. Single cylinder motors do vibrate.

I didn't need a bag of 25 spiral pins. I just needed a couple of them and paying $8-$10 for shipping a couple of pins is absurd.

I bought a bag of 25 pins and sold at least 15 to different Cub owners for a few dollars a pin.
It's your Cub....do as you want.
