I took a 1/2” dowel and drilled a 3/8” hole about 3/8” deep, then drill a 1/4” hole through.

Then to make the bottom, I took a 3/8” dowel and drilled a 1/4” hole through and glue the spring in place. and put a cap on the top of the bag.

Here are some pictures of the trailing arm, shackle and axel. Still in the test fit mode as I haven’t made the drive shafts yet. As soon as I get it complete, time to start on the front.

Looking good, and can tell already it’s going to be a winner!!!
Your going the extra mile on this one.

I just thought I would mention that Harbor Freight has a kit box full of springs for like $5 for those in the need.

This is what I had in mind for the front to have a working suspension for the front. Let me know what you think. I plan on cutting the ink pen springs down more than I did in the back.
