You sure you didn't pick up the elves' shop calculator by mistake?  :Lol:   :cheers:

And here we are at the end of this day.
3 of 7 possible sets are made already another 4 to go.
All three con rod pairs assembled at the dummy plate with 4 bearing blocks and surprise, it is still possible to move by hand.

The arbor press has finished the job to set the pin in one web.
Now the conrod assembly.
A 9 mm pin in a light slip fit as an additional guide.

Hi everybody, I will try to show the way how the assembly has been made.
First another jig was necessary, as a stop for the press fit.
Than I have measured each stack of the con rods and web pairs.
The relevant 6 mm pin for each assemble has been made the same length as measured.
A new champfer each side was made again and the pin set the first tenth by a hammer.
Now cleaning and adding some Loctite 646.

Say in you BEST Forest Gump impression - "It happens."
I'll blame it on the elves, as usual...   :LittleDevil:

So, here we are, 8 weeks after my knee operation. I'm doing well,--no infection and minimum soreness. I'm just beginning to walk around my house without using a cane. My energy levels are far lower than I had wished, but apparently that is not unusual at this stage of the game. I got a phone call from my supplier today that my #2-56 brass threaded rod is in, (it's for the distributor) and I will pick it up tomorrow. Most of the energy that I do have right now is going towards my powder paint booth. I am setting here surrounded by box fans, furnace filters, and various pneumatic bits and pieces. Riding two projects at the same time has never worked that well for me, but I will keep you posted as I progress.---Brian

Engines / Re: Marcher twin cylinder marine steam

Hopefully the boiler has been pushed on a bit this week ;) Silver soldering is the part a friend is helping with!


The engine Iíve done quite a bit more on , Made the eccentricís , the straps completely, the eccentric rods and offered up the steam chests!

I thought to make a little registry lug from copper, form to the centre port and have it proud to engage the cylinder block port, That way I can pre-drill the chests and line them up and transfer punch the 4 holes perfectly !
