A modest start: Elmer's Opposed #30
« on: March 19, 2014, 12:21:33 PM »
Yesterday evening I had time to descend in the cellar, where my workshop is.
Now you have all seen aluminium sawed, milled, drilled and tapped, so I give no pictures of that.
Here's what came up with:

The macro lens reveals what I didn't see with my naked eye (non enim est aliquid absconditum quod non manifestetur).
There is a lot more to do on these two pieces!  :o
Lunchtime is over, so back to my duties.

See you next time,

Thanks Bill,

Last night I made the bearing and the rocker arms.

At assembly the arms were 3 mm too short  :( Some mistake in adding up.
Well, no disaster here. I'll make a correct pair soon.

Some progress:
The cylinder was made out of 30mm roundstock. It was the worst aluminium I ever encountered. Soft and gummy. I had to clean my drills and mills every few millimeters.
I used lamp oil and denaturated alcohol.  :stir:
The bearing and the shaft went well.
The rocker arms are now the correct length but need shaping.

 All the best,

GertJan

That's some nice progress Gert. Can you do us all a favor and resize your pictures in future posts to either 640x 480 or 800 X 600. These mega sized pictures are hard for many to download and for others to see without having to scroll around the screen. Thanks in advance.

Here's a picture of the engine as it is today.
I finished the new rocker arms, the screws, the pistons and the connecting rods.
The connecting rods are not very well made, so I will make new ones.

I remember a buildlog of this engine by Metalbutcher on another forum, but I can't find it. Does anyone have a link?

All the best,

GertJan

A coin... Where are my foreign coins? At last I found some.
As Zee lives in the USA, it will be an one cent coin, left over from my daughter's half year in Riverside University California.
Do I have to provide an Euro coin or a Pound coin as well/ ;D ?

All the best,

GertJan

Euro works well too.

No need for the funny money.  ;D

Ah you seem to have the same toilet paper as me! Those are some really small parts, great work so far, I'm enjoying watching this!

NO
use a rule or a ruler or whatever you want to call it
everyone has one.
not everyone has a coin from every country to be able to work out how big something is !

Thanks for the remarks.
The eccentric and the arms were made.
Something went wrong, as nothing moves now. :shrug:
I hope to figure out what, because I made every part according to drawing and measures.

But first a  :smokin2:
