I was recently given a tile saw, but want more cutting height with it.
Has anyone here ever converted a 7" tile saw to use 8" lapidary blades?

thanks

The rim speed will be higher but not so much that I would worry about it.  If the arbor runs true you shouldn't see any problem other than possible glazing.  That's not a problem to be concerned about.

I, as well as several of my friends have put a good lapidary blade on 10" Harbor Freight tile saws and they work great. The higher speed may cause the blades to wear out sooner but I have not seen that as a problem. I just spin the blade dry of the water when finished and spray everything down with WD-40 to prevent rust.

    I just purchased a 10 inch tile saw from Harbor Freight for $219.   Coupon was in a local sales flyer but they had them for $229 in the flyer that came to the house. If it is in your price range and you need a trim saw you may want to go take a peak. I have 4,6,8 and 10 inch trim saws but none have the room of this critter. And with the slide table it will really make trimming down the big slabs quick and easy. The blade is really thick and true but was only $31. Option B which I also did was buy the 6 inch trim saw with no motor from Lortone. I do love that saw but messy like every other trim saw I own. It has been worth every penny as well. Added a sheet of wood for the base, old $10 yard sale motor and $5 drive belt. Took an hour to build.

Yep
I took a harbor freight 7 in and converted it so it would work with the 8in blades. After I was done I can use any size bore ect. I had to do a lot of machine work to do so. The first thing I would do is see if the 8 in will fit on the arbor if not then a lot of work will need to be done. I had to take parts to work and turn them on the lathe.

Yea it was a pain but I had the machine shop to make it happen.

I have done it also, but I just cut the slot a little bigger and had not problems with anything except I had to shim the bottom of the saw up so the blade didnt cut a hole in the bottom of the water tray.

I then ran onto a batch of 7" lapidary blades so I have about 100 of them to go through now so I am back to the 7" blades.

I would, but I'm in Canada (the land of rocks, but no lapidary equipment).
I could not afford shipping, but thanks

I was under the impression that EBAY has a web site for Canada. Never been on it but you Canadians may find it a good place to check out.

It isn't hard to add a shield to the front to reduce the splash to a minimum.  I use polycarbonate (lexan) but anything can be used.  Take a look at a Rock's trim saw to get the idea.

They do, but the stuff listed as being shipped from Canada is extremely limited.
