It might be that if your saw is a re-branded Grizzly a Grizzly riser block will fit it. You just have to take some measurements. You will also have to check to see if there are any bumps, holes, tabs, etc. made for them to fit together. This may require some disassembly to find out. There are also some other components you will need; extended left side blade guard, upper guide support arm, and upper support blade guide. When I put a riser block on my Delta 14" some years ago, I found the block and upper guide support arm on Ebay. I made the rest from 1/4" acrylic and sheet metal. You might be able to do likewise.
I question whether your 1 hp motor is strong enough to resaw wider material. My 1 1/4 hp is just barely adequate. I can resaw 5-6" but it is slow going.

 

Thanks for the feedback. I think I can make one fit from grizzly. I'm trying to get the dimensions of their riser now.
Agree on the HP. That is my concern that it won't have enough power. Resawing about 5" with 1/2 blade is slow.

 

Try using a 3/8" blade with 3-4 tpi skip tooth.

 

As a followup, I decided not to use the riser block. Decided with the weak 1hp motor wasn't sure how it would work. I'm restricted to about 5 1/2 inch resaw, but I can work with it.
In addition, this saw is restricted to a max 1/2 blade. Decided to try a 3/4 inch blade on it. Works fine with no issues for that width of blade.

 

Probably the smart move DW. I will throw in my two cents for the next person. I put a six inch block from Jet in my 14” porter Cable. That saw has a 2hp motor believe it or not so it probably has the power. The saw became quite finicky after the mod as far as getting the guides right and finding the right blade tension. I would probably not recommend it for any 14” saw. Just seems to be pushing everything to its limit. I’d look into 17 or bigger if you really want decent resawing. There’s a 19 or 20 inch Cantek at work that does a pretty good job. I been eyeing the 19’s over at grizzly.

 

My experience is just the opposite. I put a 6" riser block on my Delta and increased the motor size from 3/4 hp. It works beautifully. It probably is not as fast as a larger machine, but it serves my purposes.
