This is a build log for Thav's first Mendel build. Parts were procured over a range from July 2010 to January 2011. Build is taking place in Raleigh, NC.

Parts

RP

My main bot plastic parts were provided by Steve Degroof on a Darwin. The parts required a bit of cleanup, but appear as if they will work.

Vitamins

Purchased from Berrybros on the reprap forum link in November 2010. All hardware parts were included in this kit except for the mudguard washers and jigs. Found some mudguard (fender) washers at Ace Hardware locally, 3/16"x7/8" that seem to work well. M4 washers were extremely tight fitting, taking a lot of force to get down on the screw. This is extremely frustrating, so I would recommend that after you check your rods for straightness that this is your second quality check for vitamins. Jigs were cut from plywood to length, along with some of the measure distances.

Thin Sheet

Opto flags were cut with aviation snips from some left over pieces of straight aluminum duct I had.

Thick Sheet

Do not have yet, looking to procure from a water cutting prototype shop locally.

Electronics

Purchased a set of Camiel's Gen 6 electronics second hand. Includes optos.

Motors

Purchased a set of 4 NEMA 17 steppers on ebay. These came with gears that I have yet to be able to remove.

Got it! Thanks to NewPerfection Forum post

I had these steel wrenches around from these bicycle shaped planters I have.

I used them to get some support under the gear. The vice is NOT clamping the body of the motor, just supporting the wrenches

Then you just get your punch in there on the shaft and punch away. On one I sort of shattered the lip on the pulley, making it hard to get the wrenches to catch, but it still worked out fine. Remember to give your motor a soft landing spot!
