Yes, I decided to paint it.
As the shape reminds me on my FALK eccentric press, it will be painted in darkest green with blank metal edges.
After finishing it I will try to make a short video of it but don't expect too much as I'm a video idiot...  ;D

Look forward to seeing it all painted up.

I am interested in what kind of paint you are using.

Any chance of a video of it running?

Did you decide on the finish?

Nick, if you want, I can ask Wolfgang Bengs, if will let go another prototype and how much he asks for it...

From the very beginning until now, including the connecting rod tomorrow and some details like the adjustment bolts aside the sled and some more fine tuning & adjustments, it might have taken nearly 50 working hours to build it.
One more skilled model mechanic than me with a better machine tool equipment than I have will make it possibly in less than 30 hours...
Oh my , that's quite a bit of time invested ...you made it look easy.

Well, a rough finished one will bring $290.90 - cost of kit $145.83 = $145.07 profit / 50 hours, means you would get just under $3 an hour to build one…

I would have paid that in a minute.

I thought it would have brought a little more. I would also gladly pay that had I remembered to watch the auctions end  ::)

The fun of building comes a little too short for me with these calculations.😉
when I build things for myself , time doesn't factor in to strongly for me , when I'm doing work for others...it does.

As I already said, on more skilled and better equipped mech than me will do it in less than 30 hrs....
So you'll earn $ 4.83 / h ... I bet some latin fruit pickers in CA get less...  ;D
"I bet some latin fruit pickers in CA get less"
you might be very surprised , they wont work for next to nothing like in most modern society's , there are plenty of jobs out there at good wages for those willing to work.

Gunmaker's Acid would be my first choice. But there are very different opinions.

Now I only have to decide if I paint it or if I dye it to antique metal with gunmaker's acid...

After the little "SCHOENNER" interruption of yesterday, I made it today to finish the bear with the punch fastener... The connecting rod will have to wait until tomorrow..

Yesterday:
Oilers drilled, tapped and installed, temporary clutch pedal iron wire replaced with 2mm brass wire and homebuilt adjustable fastener

Today:
eccentric head bearing parts turned, drilled, tapped and installed on matching shortened shaft

In the background my latest acquisition, a 8in tall 1910 J.FALK cast iron Band Saw ... never seen one before...  :o

Today in the workshop... The apprentice to the boss:
"Boooooss, I've got an ideaaaaa ... Instead of turning the two step die out of the solid steel, and grinding until the doctor comes, it would be much better to take something that is already half-finished" ... 8)
 
[attachimg=1]

... and the boss answers the trainee ... "Yeeeppp, doooo ittt, that saves time and material" ... ;D

In addition, the die is now also exchangeable ..!  :o

Nice model and it looks easy to build - most of the parts are
milled - you only need a lathe. Bengs has a good one
Reputation as a precise model maker.
Hope to see it working soon, Arnold

Next day I drilled 3 holes 1.6mm and tapped M2 threats to fix the front mask to the body.

This may be soldered too, but as I worked exactly and it fits tight I won't...

OH YES , I'd be very interested in this build (may want one myself one day)

Build two Bruce  ;)  :D
Build 3 Rainer...lol 😄

Haha, I like the way you think 😆

Four days ago I received the kit and started (after some reading) with deburring the column body, front mask and base plate.

[attachimg=1]

The front mask had to be bent to match the body.
