Hey Dave, thanks for the tips! The seat pan is I think a solo seat, just a flat piece of steel with a slight contour to it (just like a majority of your seat pans). I'm planning on using 6/7oz veg tan as that's what I have on hand. I don't plan on making seats full time... just thought I'd give it a shot, so I don't really want to invest in a whole side of a different weight if what I have will suffice. I do have some 5/6oz too if the other is too heavy.
How much larger would the top need to be? After the bottom is on and the padding glued down do you just put the top piece on and see how much it needs to meet up from there? It appears the goal is to have the seam in the middle of the padding.
Thanks again for taking the time to offer up some tips! I appreciate it.
