Here is a link if it works.

Out of curiosity.... Are you going to cover the 2 bearings for the saw blade? If not you will gt rock crud in there and seriously reduce the life of those bearings.
Other than that... it looks great!!

I have an 18" Lortone saw w/pwr feed, and I love it, however, if I was building a new saw I would probably go with a gravity feed as it allows the blade to work with the rock instead of against it, which is better for the blade.
I would however, also add a set of springs to the ends of the shafts that the vise rides on to absorb the impact of the vice carriage when it breaks through the end of the rock being cut and that way the vise doesn't slam into the back of the saw.

Love the build, hope to be working on a 6 inch and maybe a 10 - 12 inch for myself.

Yes Mario I will be putting a cover over the bearings also screen to catch slabs. I'm going with power feed but if that fails gravity feed will be added.
Good lock on your build and don't forget to post pics.

you must have given it a jolt just in the right spot; thinking of IGOR, but is the blade turning towards the stone or away?
