Tumbling blocks are just diamonds of 1 – 3 different colour or grained timbers with a 60 and 120 degree.
I cut mine with a Incra Mitre Express and a Magnaswitch used as a stopblock.
I have a RAS but hardly use it.. you could set up the 60 degree cut and a stopblock but it will depend on how accurate your RAS is to get the 60 degree,,, that is why I use the Incra.,,, the accuracy.

Thanks Larry,
My intent was to build a jig that goes on my RAS and to leave the saw cut at 90 and the jig set to 60.
I hardly use my RAS also and I thought I mite use it more if I made some jigs for it! I don’ know the accuracy of it but maybe I’ll find out! Its in the pics of my shop.
Thanks again!

P.S. I was about to send out a search party, you have not been on in awhile.

i tack a straight board back by saw and pivot it ( make it long enought to clamp front edge to table ) , adjust until 3 pieces make a tight joint then make small stop in line with set angle board (tack to table ) then put end stop ,
so length of piece is same as crosscut angle end . make sure you bevel lower corner of all stops so sawdust does not
disrupt the angle or the length of parts . you could do this on a ply ,and make this jig to reuse later .just raise saw .

to make jigs for ras i iether clamp ply or drill 2 holes down through ply and saw table , and glue dowels to ply ,
so i can drop jig on saw tablle and just raise saw .
