A little more info on the mount over the wheel well...
This saw isn't something I intend to use often or hard. It'll see occasional use at most, so if I have to smell a hot saw a couple of times a year, not a big deal to me. It does take up cargo space, but I don't often pack stuff over the wheel well. I didn't like the idea of storing it outside or using the third row grab handle anchor sites because it seems too visible to me and might invite theft. I have loppers and a bow saw secured to the third row grab handle anchor points anyway.
I used the third row seat anchor to secure the tray. The single bolt on top of the third row seat anchor is not level - it sits at about 11 degrees. I took a short segment of 1" square tube steel and using a cutoff saw, opened the tube longitudinally. I put this in a vice, crimped it together, and welded it. Came out at 9 degrees. Close enough. I welded this to the base and then turned my attention to the rear anchor points. Using the same bar of 1" square tube steel, I cut wedges into the pipe, bent and rewelded it until it held the tray level and the holes lined up. I tucked the whole outfit as far forward and to the side as I could.
As far as the bracket, I started with a piece of scrap sheet metal and then used a 1" flat bar to outline the perimeter of the saw, giving it a tray to sit in. I welded this to the sheet metal and then decided a bungee was the simplest way to secure it. I don't compete with my LC or get too crazy with it, so a rollover is unlikely, but I like the idea of having it secured.
With the saw mounted, I rounded up a couple of MSM bottles - one for bar oil and the other for 2-cycle mix. They fit reasonably well into a short piece of ABS pipe. The short segments of pipe were placed in ABS caps that were anchored to the sheet metal with three short bolts each (& epoxy). I then ran a piece of bungee over the bottles to keep them in place.
I then welded a carriage bolt to the sheet metal that was long enough to stick through the bar tool. The bar tool slips over the carriage bolt and a wing nut welded to a washer holds it in place.
Finally, I built a small box out of sheet metal and welded it to the base so I could store an extra chain.
I've attached a couple of extra pictures, but they're pretty dark.
