Andy I don't have plans but surface grinders can be and are often simple mechanically. The table can be driven left to right with a hand wheel and some cable for example. The biggest problem for a DIY approach would be making the structure stiff enough to work well as a grinder. To that end the vertical arm and saddle assembly will likely take more metal than the average Gingery machine. The base could be a big chunk of steel so I don't see that as a problem.
The best suggestion these days is to do an Internet search. I know there are at least a couple of DIY surface grinders out there. Plans are another thing though.
