Nice work Larry! I've got set of castings for this engine also, sitting under the workbench waiting for the right time ;) Nice little engine. Cheers Jeff

Hi Austin. Thank you for the intro and welcome to HMEM. Cheers Jeff

Welcome Alberto!

Hi Billzilla. Yes I've heard nice things about the UP! printer, but it's just a bit out of my price range. :o Cheers Jeff

I'm about 90% done at the moment and don't have the numbers crunched yet but I'm figuring it will be in the $400 range. The print bed is 8.875" square with a z axis of about 4". I haven't loaded the firmware and run the motors yet to test the actual extruder extents, but I'm guessing 7.5" - 8"...

Stan, I'm building a RepRap. reprap.org And although the little wobbler will probably be printed ::) the main idea is to use it to print patterns for sand-casting. Much easier than working with dead trees. ;D Cheers Jeff

Glad to hear you're on the mend rero. Thm: Cheers Jeff

The other day I had to laugh and cringe, a kid blasted past me in a large displacement crotch rocket wearing only tennis shoes and a pair of shorts. :o The first thought I had was "Man, that's going to be a real mess to clean up...." I gave up riding several years ago after one too many SUV's...

Hey... Who you callin' old? :big: Great work on the motor and the plans Ken, not sure I'll ever get one built but one never knows. ;D Thanks and a KP. Cheers Jeff
