saw buck for vinyl siding

[Salty]

Does anyone know of a source for plans on building a saw buck for cutting vinyl or aluminum siding? Many years ago we built these things out of plywood and 3/4" boards. The idea was to create a channel where you would slide the panel into it and the circular saw would slide on runners at 90 degrees and whatever angle you needed for the job. It also kept the siding panel flat and straight in the channel. I want to build one instead of spending a bunch of money buying something I'll only use for this one job. I have some UHMW and have a rough idea but would like some sample images if possible.

Delta used to make this thing that is sort of the idea. Unfortunately they quit making them and they were expensive.

Would a CMS not work? I guess the vinyl siding is too wide to cut in one pass? What about making a cut then flipping to finish the cut?

Probably of no use to You, but a friend of mine uses a radial arm saw the He made somewhat portable. He sets it up on sawhorses, the blade is turned to run backwards. That is all I know. Bill

Well, as usual I got another idea and it ran its course. This is another of those reasons I don't throw anything away that I think may come in handy later. I built one using a modified router crafter that has been rusting away in the garage. The whole rail/saw assembly pivots while the piece to be cut slides into the channel.
I haven't cut any new siding yet but I did some test cuts of 1/2" plywood. With some tweeking it will work fine. It pivots to 90 degree cuts and then to the cut for the 4/12 pitch. Because that is such a long cut, almost 29", I doubt a radial arm would travel far enough.
I will be able to widen the channel later to do the soffit cuts.
