Half empty, half full - MT 137 thru MT 138

[barksalot]

Got the support arms and the hardware for mounting the mechanisms done.

The mounting hardware is a clamping rail for making adjustments. It will allow me to move the mech inwards or outwards a few inches for tweaking or I can make the components larger or smaller and still be able to make adjustments to fit them to it.

Dear barksalot,
A green dot for sharing your built materials.
You are one of the rare contributors to the defective arm of the balance (versus the other arm, full of theoretical arguties and virtual clues).

Hi Barkalot, I like the quality of workmenship you demonstrate in your builds. The presision and patients required to build a test wheel of that caliber is something I'm always trying to achive.

I've always though that the movement that Bessler talked about would be found while tinkering in the shop, something unexpected perhaps.

Keep up the good work, and thanks for sharing your build on this forum.

Best of Luck

Nice construction.

Useful for the MT138 implementation?

I have got enough structural parts cut and drilled for 4 mechs, plus a few extras in case I flub some up, but only 2 mechs worth of completed structural parts.

Now I will start work on the pivot pins which will be made from 1/4" hot rolled steel rod cut to length and some grooves cut for retainer clips.

I have been concerned about the dimensions of the parts. Thinking they may be to thick to allow them to fold up well when they close. Certainly to down scale is more difficult than to up scale when using the materials that I am working with. I think I have a work around for the problem, if not then it means completly reworking some of the parts if not all.

I stopped work on my mech about a week after my last post. I just felt like I needed to step away from it for awhile and think about some other pursuits I am considering.

A few days ago I got my preliminary assembly out on to my work bench and discovered that I had made some errors in assembling it, so I was starting to get burned out some.

Maybe I will get the motivation back soon to get working on it again. At least I am thinking about it again.

[barksalot]

I have made new parts because I changed the design some. At the same time I addressed the thickness issue I was worried about.

[barksalot]

I think I am done with this for now, I just do not feel like working on it because I want to do other things. I am not going to let this dominate my free time anymore. It will be set aside to be continued when I feel like it.

With this last try I changed the scissor mech by eliminating the taper shape.

Here it is at rest.

edit- Wow 100 posts for me and it only took a little shy of 6 years.

I have a new variant to try so I am getting the shop organized to do wheel work again.

This variant is a little bit of a departure from what I was doing but it still stays true to my thinking about MT 137 and MT 138 and the hammer men ratios and storks bill. It will now have a good connection with drawing B of MT 138 and will also connect with another MT drawing that I am not going to mention at this time.

Barkenough,
you have done a nice work, but if you allow I have 1 cent:

If I was you, in my project I would be concentrated in the variation on radius - elongation - not tangent to wheel.

Best!

There is no over balance here.

Oh well.

Back to setting the wheel aside while I think some more about it and do other things.

I thought I would bump this thread to sort of button it up and say I am not working with this idea of inverting one half of the hammer men toys any more.
I have moved on to a new idea of how to use them.

In 2013 I built five variants of this new idea and will soon begin fabrication of the sixth variant as soon as the weather breaks and I can get back into the shop without spending a small fortune to heat it. Man this has got to be one of the coldest winters I have ever seen.

This new idea will get a thread all it's own when the time comes.

I will agree to that, and throw in a bitch! The demand for natural gas to run three local co-generation plants drove the price of gas up 18%. And of course this is passed back to the electric consumer by another increase in the electric bill.

Today we finally got a hint of warmer weather with a daytime high 45 F, tonight it is expected to drop to 30 with a windchill of 22.

Hello,

I still personally thhink, half full, half empty meant, that the active part of the wheel, was in one left or right section of the wheel, not 'working around' the axle.
It was either left or right from the axle. And I think too, that in the Gera Wheel, it was most efficient, because it did not have to function the other way around.

Bessler discovered something, that was somehow stationary inside of the wheel.
And with the Gera wheel it was only on one side.

my personal opinion.

Kind regards

Blitz
