After I tried a couple of helpers to use a hand operated circular saw in a type of jig to cut small pieces of wood, I decided to build a cross-cut-sled, finally. Since I had an INCRA Build-It Starterkit around, which I ordered from Dieter Schmidt Feine Werkzeuge,
I used that and an additional Build-It small build it panel as well as two miter sliders to build my sled. Of course you can do that with scrap wood as you can see in a lot of youtube videos.
Apologies that I don’t have detailed step by step instructions how I build that sled. I can just present you the final sled here.
I calibrated the sled using the five-cut-method as described in the following video:
A PDF document describing the 5-cut method can be found in the video description or from this link.
The detailed description of the INCRA Build-It System can be found on Incra’s website website.
