Mine were a little tight so I used a letter sized drill a little larger on the upper holes. When you drill the new holes they will be directly over the others you drilled if your drill press table is 90 degrees to the spindle and you don't spin the orientation of the block. Insert a pin in the hole in the board and put your previously drill holes in the block over the pin. Drill a hole using the longer bit with the table adjusted so the bit will drill about 1/2" deep at the full extension of the ram. You will also need to fasten a board to your drill press table. For drilling the mating holes on the other end of the block you will need a long and a short 1/4" drill and one of the pins. The second hole can be accurately located on the arc. You can then set the block over the pin and scribe an arc with the transfer pin.
Install one pin in the saw frame and a transfer pin used for locating dowel holes in the other. Locate and drill one of the holes in the block. You need to use some Dykem or a thin coat of lacquer on the machined surfaces of the new block to help see you lines.
The scary part for those asking about the mods was how to locate the pin holes. I modified the H3051 Kit (also available as H3051P) for the G0555 for a friend and also installed it on my older Delta saw before delivering it to him.
I know this is an old thread, but I thought a little update might help. I didnt have to adjust the blade tracking, it was still dead on.ĭon't hesitate to ask if you have any questions. I installed the 105 inch blade from the Grizzly kit, tightened the blade and everything worked perfectly. The aluminum hex bar was $7 from one of the online metal supply places. Its just a guide post, with no stress on it it could have been aluminum to begin with. Unable to find a piece if 7/8 inch hex steel, I used a piece of Hex aluminum and it works just fine. The hex guide post, thats not in the Grizzly kit. The right blade guard will work, had to enlarge the wing bolt cutout slightly with a file. The left blade guard will work, though I had to file one hole just a little bit. Drill new holes and install the pins supplied in the kit, reinstall the original pins in the Delta. The pins press fit in the top, but just slip into the holes on the bottom. The holes in the bottom of the riser are larger than the holes in the top. The holes in the Grizzly riser don't line up with the Delta pins/holes. Mark the hole locations on the frame of the saw, then set the new riser on top and transfer the hole locations. Pull the 2 pins out with a pair of visegrips and a hammer. I unbolted the top half of the saw, its not heavy like some have said. Sometimes on Ebay you can find a Delta riser block, not often though, for about the same price, and thats all you'll get. I purchased the Grizzly riser kit P/N: H7316 for about 60 bucks. I have an older Delta/Rockwell saw with the hexagon guide post. I want to post a few comments on this procedure, as I see this question comes up every so often.
