BTW I wonder why nobody is respecting the cheap two piece
end housing design. How can you beat a low tech replaceable hard steel
wear surface that has been nitrided? The 4130 steel plate can be laser
cut to shape at low cost. I was just thinking that I need to put
that up on the web site.

Paul that is what we are working on now.  That makes a whole lot of sense.
Hopefully we will be able to get the first housing cut today to use as a
pattern.
We have just been so busy of late that we haven't had the time neccessary to
put it all together.
We also are  considering machining the aluminum from plate stock and just
adding the steel surface to that.  Will see how it goes.

Good for you Royce. I think it is going to work great. If you scale these dwgs
I think the plate is 3/16th thick but I would not be a bit surprised
if .125 thick would work. Save a bit more weight and improve the heat
transfer.
