Thanks, but unfortunately I have to pass. I have an ever growing list of projects on my plate, and with the exception of the Drylin bearings, this one was built with materials that I had on hand, which I now no longer have on hand. Also, I didn't draw up any plans for this one (bad idea) and just made it on the fly.
If you decide to build one, I'll gladly share some basic dimensions.
This is the ratchet I pickedm mostly because the nose is relatively uniform diameter (just a slight taper): https://www.amazon.com/gp/product/B000MQEKTY

If I were doing it again I would just bore the the carriage block for the Drylin bearings and use external snap rings to secure them. That would eliminate the side wings, 20 holes drilled, and the alignment issues to get the pillow blocks properly aligned for smooth travel, but the pillow blocks are here: https://www.amazon.com/Furiga-Printer-Linear-Bearing-Bushing/dp/B08BZ48XZN

For springs, you're on your own, like I said, they were RC truck shock springs, but they've been in the bin for years.
. I appreciate the response and the links. I'll give it a go when, like you, I have an opportunity.
