I'm new to the forum and in fact this is my first post. I was lucky enough to find a slightly used 3520b recently and grabbed it! Anyway I saw somewhere, someone added a larger shelf to the headstock and I have been looking high and low and just can't seem to find the post. I'm not sure if it was here or elsewhere but I thought this would definitely be the place to ask. Any feedback would be helpful. I had a smaller Grizzly machine in the past onto which I added a larger shelf and now I miss it (the shelf that is.....)
