Or maybe this should be 'what exactly is inside a Biax'?. Forgive my ignorance but I suspect will never be one of those lucky guys who own a power scraper. New ones like the BL-10 go for <cough> 3200$U. Used ones.. I rarely see on ebay anymore, they get snapped up quickly because people know what they are worth. I know, some of you will say just buy the hand scraping tools, and I probably will when I embark on a few simple projects.
But I just wanted to explore - what makes these power units so expensive? Super accurate mechanism, heavy duty tool meant to last a lifetime, or maybe extremely low customer base even offshore replicators don't want to clone them? I see they have adjustable stroke length and controllable stroke rate. They look like big amp motors that convert rotary to linear motion. But what else? Seems to me as a qualified Youtube observer expert that so much of power scraping is a hand/feel thing. For example, here are the guts of some random $200 Sawzall. Why couldn't we repurpose these mechanics, attach a good quality scraper blade assembly & accomplish something similar? Am I completely naïve & off base? If so, why?
