PC 521 stair template owners manual

It was interesting to see how that worked after going through the other thread when you were trying to find this manual. You had to lay the stairs out the traditional way first. I thought maybe you only had to lay out one tread and riser just to get the angle but this jig was just for providing the outline so they could be inset.

I had the porter cable 5020. Does not conform to 2020 specs . Does not give you a tread longer than 9”.
I have the cast iron jig of probably 40 years ago. Very useful and versatile. Still use it today . Requires shims under treads and risers.
Once you use it a couple times it is a cinch

I looked for years for a copy of the instructions to my 521/ust stair template and was delighted when you posted them . I found the set of instructions I posted when I purchased some old Porter-Cable items at a lawn sale and found the instructions in the catalog. So I thought I would share as well. Porter-Cable now gives out a link to your instructions that you posted online
