Aye and that's the rub...after you find out that the bag o' surplus parts you bought are pretty much all useless and you wasted a fair amount of time and effort on trying to make them work! If you go into this thinking you're going to save a bunch of money by getting a great deal on a frame or a slide assembly and then shopping around for parts, you're in for a rude awakening.
And then there's the matter of what is your time worth on this labor of love because at some point you'll get fed up with the whole deal and just set it aside for awhile till you have the patience to pick it up again. Of course all of these things are forgotten (at least temporarily), the first time you pull the trigger and everything works, just like it's supposed to!
