Would like to borrow two disparate items

Hello, if possible I would like to borrow two items for a few days each.

First, a small chainsaw (with its batteries and charger, unless it’s a DeWalt; I have those).

Second, an undercut router bit, like the one pictured. I could use either a bottom bearing (as pictured) or no bearing, but a top bearing would not work. Ideally it would be 1/8" or 3/16" cutting thickness, and 1/4"-3/8" cutting depth, but I mainly want to do a proof of concept test right now, so that’s not essential.
