Need Help!- circular saw guide automation!

[carlo mateo]

Hello there!

My project consist in automating a "track saw" that I own (I build small wood boxes). and I know there has to be an easier way to make repetitive cuts... as I did not find any solution... Im building it!!

The "tracksaw" is a guide system that allows the circular saw to slide and cut straight pieces of wood. I attached a picture so you guys can have an idea of it

My goal is to use a leadscrew drive system like this one cjamasterworks to build a carriage to move the saw back and forth with a push of a button so to speed up my cutting time and sound as I want to enclose it!! The total length of travel is 64".

Im planing to use this Leadscrew:
Major Diameter: 1/2" (in.)
Threads Per Inch: 8 (Threads/in.)
Number of Starts: 4
Lead: .500 (in./rev.)
Effective Threads Per Inch: 2 (Effective TPI)
Hand: Right Hand

where I REALLY NEED HELP is in figuring out how much power and torque will I require to make the saw move back and forth and cut wood at 1 1/2 inches thick at most. Also do you think that the half inch .500 lead leadscrew be enough to move it steady?

The saw weights 8 pounds!

would a nema 23 276 onz/inch be enough?

Thanks a lot!!!

Thank you so much for the link! I really appreciate it!!!

after talking with Chris from cjamasterworks.com (really nice and helpful fella) I will go with a nema23 570 oz and a 3/4 leadscrew with .500" lead for my project!

OMG!!!! yeah!!!!! that proves the concept!!! thanks a lot for the video

It's really interesting to see that sort of rack and pinion driver system they use, gives me ideas what I have thought using in mine is a leadscrew linear drive system... I'm still thinking about what kind of rails I'll build for my machine but seeing what others had done expands my horizon.

thanks again!

there is a whole world of rail saws out there. i have used them and they are great.
