AB Hammer design wheel for CLaNZeR to build

In the MT13 the flips have to use the pendulum solely. The flip arms are designed to be an ease of flip. Not being ease of flip for the MT13  was part of its downfall. Now when you add the ratchet in the center of the pendulum that add even more possible power to drive. Also note on the ascending side. The longer arm with the smaller weight is tucked under the axle. This help re leave the weight of the pivot of the arm and not once flipped the weight is planted to the outer wall of the wheel. This means that it will need a rim or stoppers.

Barrowed from the wiki pages of Besslerwheel.com The statement from Bessler about the MT13 and this design of mine addresses IMHO what Bessler meant to make a newer workable design like.

"No. 13: This is a new weight-invention, with no belts or chains but each weight is separate and free except that each has an interval arm C with which it forms an angle, and on the cylinder hangs a figure which has below a weight in the shape of a half-moon and above a small wheel B over which the arms C sweep and lift themselves up at D. This invention would be very good for running if not so much friction were present or someone was available up by D to always lift up the weight with lightning speed."

So this is why I picked this one of my designs to for this string.

I like this one AB, however I think the use of a sprague clutch instead of a ratchet would be better.  much less friction, more positive lock.

Nice AB, I like it.

Have you got any materials, dimensions or weight in mind?

Cheers

Most wheel work I start off with 2 ft to 3 ft wheel blanks, so lets start with a 3 ft for this one. Oversize weights are not necessary, but we want weights that are comparable to the size of the wheel tested. So lets start with 2 lb and 1/2 lb for the flip arm weights. 1/2 x 1/2  or 3/4 x 3/4 square tubing steel for the arms. I cut my own weights from larger bar stock into short cylindrical weights to keep the weights a small as possible. The pendulum weight 5 lb should work fine for this size. On this design I would use 1/2 or 3/4 all thread and flange bearings and 1/2 or 3/4 ID pipe for spacers. Knowing that most people would have trouble making a ratchet gear. dirt diggler made a good suggestion and I believe an old 10 speed bicycle  my have the gear you need in the back wheel. For the pendulum you will need flat bar stock to mounting the gear and weight on as well as the flip roller which can be a roller skate wheel mounted. I am not sure where you are out of so please send me an e-mail encase I may need to make a part for it.

This should give you a good start
