Agree with Bennie, can't remember us having issues with any of the plastic end tanks on the various 20 year old radiators we've been using.
 
	Yeah I guess you're right, forgot about $200 and one month shipping on the Golpher.
 
	It's going to be a while until we see the end product on the knuckles.  Maybe one hour of actual spindle on milling time into it so far.  At least a solid day of set up and test cuts before that.  At least a day of various CAM before that.  Still think it's a better overall solution than making a bunch of pieces and fabricating them.  Assuming it works out.
