I have a Porter Cable 14" PCB330BS saw. From reading on the net, I saw others have used the Jet risers on their Porter Cable 14" bandsaws. When I first opened the Jet Riser box, it looked like it would fit right away. I also thought this was only the block, and not a complete kit! This made me pleasantly surprised that everything I needed was included for $109. The extended round post for the blade guard is included, and it fits exactly like it was made for the Porter Cable saw. I knew previously that the PC and the Jet used similar guides, because when I called Carter to purchase roller guides, they said that the Porter Cable saw uses the Jet roller guide kit since they do not make a specific kit for the Porter Cable. They were right, and the Jet kit works like it was made for the PCB330BS, so these kits are one in the same.
Like previously mentioned, you need to drill 2 small holes, which was not hard to do. Take your time and measure with a caliper before cutting. As for honing out the hole, like the others have said, this is really only necessary to use 1/2" or 3/4" blades. If you only use a 1/4" or 1/8" blade, this might not be necessary since there is enough room without expanding the inside diameter of the block. I know that the specs say the max blade width for this saw is 1/2", but many have seen you can in fact use a 3/4" 1-TPI hook blade for big resawing jobs. The wheels and tires are big enough for using the bigger blades.
So, if you want a riser for you Porter Cable PCB330BS, this is the one to get. This is closest to the kit that Porter Cable has never made.
I would estimate 3 hours time to do the complete project, and sell or give away your 93.5" blades, as you will now move up to 105" blades. Oh yeah, a nice touch is that they give you a 105" 10 TPI 3/8 blade to get started with, so you can test it once you are done. You will need a 3/8 speed/steel bit for drilling the holes, and you will need some type of sanding, honing device to make the block opening slightly bigger. Sandpaper drill bits, like the kind used for sanding holes with your drill, will also work fine. You don't need a nice finish, so 60 or 80 grit will work. Nobody will ever see this hole once you are done, so don't worry about doing a "clean" job when you are opening up the hole.
Once you are done, you can now resaw 12" thick stock with a 3/4" 1 TPI hook blade very nicely. The saw has enough power to do this with the stock motor, which can be upgraded if needed. I am sure this block would void your warranty, but if your saw breaks it is easy enough to revert your saw back to stock and only you will be the wiser. None of the mods are done to your saw, you only modify the block to fit your saw.
