    Question on Granite tops

    Have been thinking of upgrading my saw and was down at a local tool store today with some reps there. Was looking at the steel city Cabinet saw with 3 hp and the granite top. 50.00 difference in the price between the cast and the granite. So started thinking what are the advantages and disadvantages and maybe someone here has some info to share on this issue.
    Daily Thought: SOME PEOPLE ARE LIKE SLINKIES..... NOT REALLY GOOD FOR ANYTHING BUT THEY BRING A SMILE TO YOUR FACE WHEN PUSHED DOWN THE STAIRS...............

    1. The only things I would have to offer, (information only), is that Granite, once ground Flat, will STAY flat, where Cast Iron, can continue to stress relieve itself for many years and may or may not remain flat depending on the internal stresses it may or may not have from the casting/cooling process.

    2. Magnetic hold downs/featherboards will not work on Granite, but will work on Cast Iron.

    3. Granite WILL NOT Rust, and Cast Iron WILL.

    That's my $.02

    I don't have any first-hand experience with the granite tops, but from what I've read, here are a few pros and cons...

    Pros:

    • Won't rust
    • Dimensionally very stable -- should stay very flat
    • More mass for better vibration damping

    Cons:

    • Can't use magnetic accessories like featherboards or Board Buddies
    • More difficult to drill and tap holes in the edge for attachment of new fence rails and such
    • Potential to crack or break the table dropping something heavy on it
    • Potential to break out the miter slot if using a t-shaped miter bar and you lift or drop the miter gauge while removing it

    I should stress that the last two items are only potential problems. Aside from one report I read from someone who saw a chipped table edge on a Steel City saw in a store, I don't know of anyone who has actually broken or seriously damaged a granite saw table.

    Hey Andrew, so you're thinking of upgrading eh. I put an order in for something but not sure when it will come so I don't want to blab about it just yet. As for the granite question I think the pros and cons have been covered by the guys above. I will add though that any stress relief from cast iron is so minimal as to be negligible. IMO the biggest gain from granite is the non-rust surface.

    One big problem with granite is in a cold workshop, the cup of coffee you rest "just for a second" on top of your table saw, will be stone cold in about 30 seconds.

    I don't mind cold coffee. I *do* mind rusty circles on my table top. I was a complete noob when I got my saw. It took me three or four circles to learn...

    Yeah, I've always been a slow learner...

    Thanks,

    Bill
