Very cool! It may be a little out of budget for this particular project though. I'm certainly going to use that in a future project!
My pikes are 12" and 14" long and I want to add a 10" zebrina, finding a log that big and coring it out would be really time consuming.
I don't know how hard it would be to find the log in your area,however if u use a auger or chain saw it shouldn't take 10 minutes to carve.
