Hi Chris

I'm most intrigued by that solenoid motor.  :cartwheel:

I seem to have seen one very similar, maybe on the John Jenkins site (?).

Makes a refreshing change from all the 'pistoney' gubbins that infests this site ....  ;D  ;D  :paranoia:

Are you sure they didn't 3D print all that?
Maybe they collected pillows from around the neighborhood and shredded them...

I don't recall whose engine that is, good chance someone here remembers or its thiers! It is one of many I took pictures of at Cabin Fever.

No, but it will “melt our hearts!”

It's not about the destination, not even so much about the journey,
but rather it's the interesting folks you meet along the way.

Still snowing outside, so a good day to play in the shops. Did a coupl emore sessions and have the four holes bored out in the first of the pump chambers. The flanges at the bottom of the holes is being left in, they will keep the pipe sections in place during silver soldering later, after squaring up the flat sides of the holes. For now, I am going to bore the same holes in the other two pump chambers, since the mill is all set up for that operation.

Between sessions on the mill, I got coats of paint on all the 3D printed valve chambers/force chambers/pipes - this is the same iron color as was used on the frames. The shop elves approve of their new climbing jungle...

The solenoid engine is not- its an electric motor.  It was built by Joe Higgins of Portland Maine. So is the Snow engine in that photo. Joe does amazing work. Joe did a couple old electric motors, mostly copied form photos or old patent drawings.

I remember walking down the line of tables, stopping at his and going Oooohhhh!  Very well done!

Continuing on today with boring the holes in the sides of the pump chambers - three of four holes done in chamber two. Looks just like the pictures I posted yesterday...

Also spent some time in Fusion designing up the check valve sets for them. Lots to work out, to make it so they can be assembled into the 3D printed housings and be able to get at the screws, room for seals, all that.

Wow!  I don't know how I missed this build, but I've just read all the posts and I must say, I'm most impressed!  The complexity and build quality are simply astonishing!  I'll be carefully following along as you progress.  Again, fantastic work!

Thanks Bob!   :cheers:

I got the design done for the check valves, and will print a prototype to confirm that it works, fits, and that I'll be able to get the fasteners in and tightened when in the housings. Should save a lot of time and metal if it turns out that there is an issue with the design - once I start making the real parts, it will be more mass production of each one so would not know of any problems till they were all made. Lots of bits that have to be assembled together in a small space.

More important, looks like middle of next week we are back to warm summer weather again! Couple days ago I mowed the lawn, then watched  it get covered in 4 inches of snow. The fun of New England weather!

Chris...you earlier mentioned of the unique design and of the large number of check valves...this obviously was a considerably difficult solution to harness  :killcomputer:

If you have 100 .... :slap: 1000 gallons of pump displacement per revolution .......this equates to ~~ 3800l litre  :ThumbsUp: or 3.8 tonnes of water coming to a series of dead-head stops within the valving and pipework, hence the considerable size/voulme of the 3 expansion [fluid accumulators]

I suspected 90% of the banging/crashing noise in Part 1 Video was from downstairs [within the water elements] with the actual steam engines being a series of substantial  woosh......woosh......woosh noises only
