I started throwing receipts away a long time ago from what I spend on this hobby...I don't think about it..If I did I'd probably realize I can't afford to do this...

I make little lists of stuff I think I need..Then I scrimp and save to buy a little at a time and set it on the shelve...

Later I go downstairs and it looks like I have all this free stuff sitting on the shelves for me to build!! (I think it's some kind of weird psychological thing)

I can pretty easily see a .60 size classic pattern plane costing $1000-1500 or more if you include pizza and beer..

Have Fun...
