    Default My DIY Stone Bridge Saw

    Here are some pics of the saw that my Dad and I built.
    Travel is 14x14 feet, spindle is 10HP, X Y drive motors are 3ph 1.5HP, the Z motor is a 1HP DC with brake. The table lifts up and rotates.

    Before this we were cutting with a rail saw,,,not fun.

    Still working on the covers for the THK rails......

    ^^ Do you mean, stone that was cut on the saw? I'll take some pics tomarrow. But the edges are razor sharp and does not chip the buttom or cross cut corners. We used a rail saw like the Blue Ripper before this and this thing makes wayyyy nicer cuts.

    I'm felling a CNC next for the sink holes that every one, very dislikes doing.

    Here are some pictures of the bridge and Z axis and a few others. The big THK's are SR85 and rated at 37,000lb each block, I know it was thousand time over kill but they were available for a good price. The Z axis has a rotating nut ball screw and two SR20 rails with six blocks. The steel plate is 1" thick. We used a chain for the drive system because it was a easy alternative to other methods and we don't need positioning accuracy as with CNC. Everything turned out excellent. There are limit switches on all axis as I found that the motors will rip the chain like nothing if the bump stop is hit. The chain is iso 40 rated at 4,000lb. There is a green line laser to help with positioning the cut. The blade is a silent core 16".

    ^^ Yeah, there is a 3hp water pump pumping 250 gal of water every 30 minutes. The water gets cleaned and recycled.

    It's pretty fun cutting with this thing

    The table was a hard one, so we found a rotating base from a man-lift and used that. We were thinking for a long while on how to make it raise up a rotate. I'll make some pictures tomarrow.

    Here are some pictures of the table up, the blue rams on both side are attached manualy to the table with the nuts on both side, it's a low tech way but works. My head was getting big from thinking to much on how to make the rams under the table.

    Default Hey DennisCNC,

    Hey DennisCNC,

    Where are you guys located? I'd love to talk with you someday on the subject of building machines. Can I give you a call sometime?

    My camera when snowboarding for a few weeks, so when it's back i'll make a video.

    Here is a pic of a 3 volt regulator that I needed to make for the Green line laser as it died after a week of use at 5 volts. They said it was 5 volts and latter told me it was a new model and needs 3 volts, but the company sent me a new one! It's a LM317 regulator.
