How To Build A Bessler Type Wheel

[johnny874]

truesearch,


I just heard from johnny874 that he is having trouble for some reason posting and he asked me to let you know.

  Thanx Webby1   
@All, this drawing is something I thought of a while ago. It's Mt 24. And while the levers never move to the outside
of the wheel, it's not really necessary. Mt 20 shows it better. And the quote by Bessler I think is one of the most important clues.
It's like I mentioned to Webby1, that by using leverage, a 1 lb. weight can pump 1 1/2 to twice it's own weight. And with what I am
working on, that is 20r*2*3.142/8 = about 15 1/2 inches. The last number is the lift of the weight. And the drop of the 1 lb. weight ?
Using a 4:1 ratio for leverage, it could be as little as 3/8 * 4 = 12/8 or 1 1/2 inches.
  And if you divide the 15 1/2 by 1 1/2, that's a ratio of  10 inches of lift for every inch a weight drops. And the weight being lifted is
also heavier. Of course, if you don't like math, then this is something that would never be.
Myself, have used rotary tools and tried this. and now I have a router, a drill press, and an 18volt circular saw and drill. Much better
prepared. I am hoping to build the main fixture this weekend. If so, then the following weekend I should be able to start amking parts.
I still want to buy a generator to ensure proper power supply for the router.
The quote by Bessler on Mt 20 "No. 20: Here the previous levers work somewhat more peculiarly and raise up special weights and turn outward to the over balance. For this reason side A is always heavier, my friend supposed but I denied. I then reminded him to harness the horse in front."
What is interesting is if the short levers rotate in the counter clockwise direction, one would be lifted as another drops. What is more interesting is the reference to "special" weights. If the weights are soild masses like any other, then what would be special about them ?

  @All,
I may modify the build process I was planning on using.
Having experience with precision manufacturing, it is something I would like
to carry over in my build. What I do understand is that I can simplify the process.
This would hurt the quality of the build. To most, it might not be noticeable, but
I would know it. There are some things I have learned when i was trained on CATIA.
It's a design engineering program that would be Cad 3D on steroids. And something
Bessler might have realized also as a way of making things easier for himself.
Since the wheel is composed of 8 identical sections, the parts can be manufactured
using parts made one after another using the same process. Then later, they can be
assembled with other parts to make what are called sub-assemblies. The wheel as a
whole would be consider a final assembly. And each group of parts that are assembled
together such as each weight and lever or pump and lever would be different sub-assemblies.
And using this concept might be the best way to go for the initial umpteenth build.
I have tried various build processes using rotary tools which is why I have purchased the
necessary equipment to work to a better standard.
  It is interesting to think about, if Bessler realised the same thing, then he might have been
able to invent aspects of mass production well before anyone else would have thought of it.
This would be as I mentioned, his wheels would have had repeating sections which would
have benefitted from being made using modern manufacturing techniques. It is a possibility.
  If I use thie alternate build method, then maybe next week i'll be able to post some pics.
It is something that most will find boring until they see it all start coming together. And it
might be this that helps everyone to understand how the mechanics work to ensure a balanced
imbalance is maintaned.

   @All,
Yep, am modifying the build process. have thought of what might be the best way to go about it without a full shop to work out of, maybe one day if I continue past this build.
Here are some pics of what I got done to day and what my shop looks like. I have 1/4 inch oak plywood I'm gluing together to make a radial router compass. This will allow me to do nice, neat radii 
The first pic is a drill jig. I still need to drill a hole in it. This will allow me to use locating pins in the boards I will be routing. This will allow everything to be as precise as possible and hopefully will ensure a better mating of the parts.
The 2nd pic is the routing fixture. I still need to add a few pieces to it to accommodate travel of the router past the board being routed.
Tomorrow I'll make the saw jig. it will allow me to use my circular saw to cut the boards to precise lengths and angles.
By taking the time to make these extra tools, in the end, I will save time and should be able to do a much better build. And if all works out, it might become a standard for other people who might wish to build this type of will as it will help to keep costs low.

@ all,
have tn
hold up a while.
need to buy a table router.
Only one way to build. and this worth doing it right.

You can bolt your router ( with the plate taken off ) to a 2" X 1/4"  X 3' piece of white wood with a hole drilled in it if you need to cut  a circle of less than 6' .
