Brian,
I am asking myself: "Am I once again trying to reinvent the wheel?"
Brian you have a lot more experience with the vintage pattern planes and better knowledge than I regarding what works best and why.
If you like the UFO best, I figure the UFO is probably the best way to go...and I really do like its lines.
So I will seriously consider the UFO.
Your info and advice is much appreciated.
Best Regards
JC

PS Any hints and building tips you might offer would be very welcome.
