Basic trim saw/ tile saw?

[Rockoteer]

What size saw/blade ?  As the size goes up so does the arbor.....like in groups 1-6 is 1/2", 7-10 is 5/8", 12-18 is 3/4" or something on this order.  I might me a little off but this is just a general idea.  (Tongue in cheek) (off the wall) (I don't know what i'm talking about)

I have a 5/8" arbor and use a 10" blade on my home made trim saw/polisher. I have a 1/4 horse motor spinning it. I cut all the small rocks on it and use my 12" slab saw for the big stuff. But, it is no problem to cut fist sized rock on the trim saw. I use a swamp cooler pump floating in a bucket for water and a return line from saw tub to the bucket. It has cut hundreds of rocks with no problems.

Ok new question?? If I build my own saw what would be the optimal size arbor for available blades?

5/8"  ...they will include adapters if blades have larger holes
These are Excellent long lasting blades, friend.

I would probably build a larger saw and go with a 3/4" arbor.  I have a friend with an 18" but it is just not big enough for some of my larger rocks.  The extra 3" with a 24 " blade would make a big difference.  I would also find the price break (if there was one).
