Just found this group

[Charles Lessig]

As a lifelong tinkerer this seems to be a great place. I have always worked as some sort of technician.
My specialty is stuff nobody, including me, knows about. Things that normal people know about are
not so interesting.

Here is a contraption that I worked on furiously for a month of so. It is a variable speed transmission
with forward and reverse using a variable speed belt drive with a 2 to 1 range.

The only thing I think new is the skate wheel differential. My friend set up the camera and I was
explaining it to him. The sound didn't come through very well though.

The differential passes through zero so it is just an infinite reduction and not a real neutral.

     

This might be useful for something.   Charles

Welcome Charles! Sounds interesting -- will check out the video this afternoon -- off to buy some steel.

Hi and welcome to MadModder. That is quite the transmission that you have built there. I'm still not sure I understand exactly how it works. You can be sure that some of the members here will be interested in learning how it works. We look forward to your participation in the various threads.

I took the liberty of embedding the video for you, I hope that you don't mind.

Cheers

Charles,  HI.

We just love contraptions.  The further off-the-wall the better.
And lots of pictures of devices and gadgets.

Hi Charles , welcome to the forum 


   Cheers Mick.

Is this THE Charles Lessig, famous for the eureka relief tool video on youtube?? If so, you should be promoted to executive member for that video alone...I spent hours watching that to figure out how it worked!! Warm welcome to the forum! 

It'll look well if you are a different Charles after all!!

hi and welcome

[Charles Lessig]

Thank you all for your hospitality. I must now look at all the posts and pictures here to get to
know this place.

I live in Maryland near Washington DC in the US. We have a metalworking group called the
Chesapeake Area Metalworking Society or just CAMS which meets in Maryland and Virginia in
alternate months. Some of our members might be here already. We have people who work
on all sorts of things so there is always something new to learn.

I showed my hob reliever, yes I'm the one, but it was hard to visualize without the lathe so
that's why the video was made. That was built because I couldn't understand how it worked
and then extended twice for hob making. The first time needed the tool reset for each pass.

My friend came up with a great way to machine the edges of disks using perforated foam drawer
liner. I had been using rubber but the perforated foam worked better.

It is very cheap and easy to find. When you put it between your rough disk and the face plate or
smaller driving plate for smaller disks it really gets a powerful grip when you press it all together
with ball bearing center. It is plenty strong for half inch steel. It's also good for routing wood and
opening jars.

The transmission was another project built because I couldn't understand how it worked.

More later,    Charles      Motto:  "Well, that didn't work"

Welcome Charles.

Like Chris, I too have watched your Eureka video several times.

I have one (bought - not made by myself) and  I agree that unless you see one in action it's very difficult to understand how it works. I have used mine recently to make clock wheel and pinion cutters.

Looking forward to seeing more of your projects.

 

Phil.
