Re: I See Springers...
For about $50. (shipped) you can get a chrome springer on Ebay... Or for about $100. or more, you can find a "real deal" Schwinn springer!!! Or one of those Monark replicas.
Your time is worth money... Sometimes (I think) it's better to pay a extra bit of money to buy something, instead of spending 80 hours designing & building it yourself. (but if you enjoy it... go for it!)
