I agree Handmade Shoes for Men is more of a coffee table book than not. I got a bit out if it, but I admit it wasn't much.
Having looked at your stuff for a while now, as long as your last is a good fit to you and the style you're looking to make, I know that you'll get it figured out. Your lasts sound like they are loafers/deck shoes. They'll work, as long as you aren't going to put much of a heel (if any) on them. Last are really tricky to buy off ebay. If you think you found something that will work, ask them to measure it with a cloth tape, the length, the ball of the foot and the instep. That should let you know if it will work for you. You can build them up or carve them down only so much. And as far as I know (which I readily admit isn't very much), you can't mess with the heel height of a last. You pretty much have to use the heel height it was made to use.
For what its worth, Jason is in the process of doing a video for his stitch down boots. You can see the trailer on Laughing Crowe, internal stitch down shoe class. He also did a video for his turn shoes that I think is really well done. Jason is a great teacher in person and it came though on the video as well. Calen did a great job shooting the first one, I don't expect anything less for this one. I believe the video will be done and ready to ship sometime in July.
