If you are going with the rudder trim like Vic's/Tim's etc, then you might want to order an extra access plate kit that is originally for the stall warning access door. It is a nice little plate with a backing ring. They are VA-195D Access Hatch and VA-195C Access Hatch Doubler. I think they are sold as a pair.
When ordering your tool kit, if you are going with something like the Avery RV-10 kit, there are other things you need to add. I would add both a #30 and #40 reamer. Use these for all your final drilling of the skins.
I also ordered a Pheumatic squeezer and would do it again for sure. Get the 4" Yoke and the Longeron Yoke. I had to buy extra 3/32" clecos so you might want to jack the kit up by 100. You will also need a straight extra long back rivet set. You will need a nibler, don't remember if it came in the kit or not.
Harbor Freight will also be your friend. Their cheep die grinder has worked great.
As mentioned above, get on Tim's site and also make sure you add the Matronics -10 site to your reading
