DIY Spring Winder

This is working model of a Di-Acro Spring Winder that was offered in the 60's for about $125. It is a very close copy of the original, with only the base being shortened slighly to fit on the bed of my printer. It can be used to make compression, expansion or torsional springs. It can handle mandrels from 2 to 16mm in diameter, and it requires about 80 hours to print.

The last 4 photos show illustrations from the "Build Notes" PDF file.

My objective was to 3D print as many parts possible, minimizing the number of parts that I need to make of metal. I figured if the plastic parts fail, I could always make them out of metal. Fortunately I’ve discovered that for the light gauge wire that I use for my project springs, plastic looks like it will work fine, with only occasional reprinting of high wear parts.

All the necessary nuts, bolts, screws, and set screws maybe purchased from BoltDepot.com for about $20 plus shipping using this Cart:
https://www.boltdepot.com/cart/222164
The cart includes the items necessary for the Cutoff and Spool Support options.

Here is a video that shows it in operation.

And here is a much better video by Dogs Barking showing the orginal version making a spring.

Added missing "Handle" files. Note that there are 2 Handle files; Handle and Handle w Forced Support. The 'Handle w Forced Support' file has a single layer wide ring around it's top to force supports to surround the part and help hold it up. if a brim does not work. The ring is easy to remove because it is so thin.
