Wrapping it up!

It's time to wrap up this build and put it up for show.   I went with gaskets today.  Since I didn't have silicone, I decided I'd try paper.  I had some vellum which I found was only 0.002 inch vs. 0.004 for my ordinary printer paper.  I applied some oil to make it "stick" (this worked well) and it looked like this:



I assembled the cylinder and valve mechanism and tried applying air before I put the whole engine back together.  I had the air on with a rather high pressure (50 psi) and the thing nearly jumped out of my hand when it snapped!   I squirted a little oil around and found I still have a very slight leak at the bottom of the front cylinder cover, and a teeny bit leaks at the corner where the front cylinder cover meets the valve chest.  I'll leave it for now.  Next time I'm at an auto parts store I'll look for something appropriate and if I ever need to take it apart I'll apply it.

Here are some pictures of the assembled engine.  It's running fine again, too.  I'll get the video uploaded and do a final post over in the showcase.













I'm pretty proud of it.  A nice engine and a super-thanks again to Stew for designing it and sharing it with me!

Todd

P.S.  According to photobucket I have taken 1134 photos for this build.   I know you guys love photos, so there ya go....

An inspirational build Todd  :ThumbsUp:

Many thanks for the progress reports and pics and certainly now moved much higher on my build list.

Looking forward to seeing the next one.

Here's the link to the showcase:  http://www.modelenginemaker.com/index.php?topic=4966.0

And here's the video so you don't need to look :)  If you've followed the build you've seen the photos I posted over there.

Jo asks what next...and yeah, that is on my mind (why is that? :)).  I'm really not sure at the moment.  I might do one more bar stock engine before trying castings.  But I have a few shop projects to do after I clean up some of the mess I created in the shop.  I'd like to make a carriage stop, maybe some soft jaws (for lathe and bench vise), a mod or two to my "new" bandsaw, etc.  I also need to adjust my mill's Z axis.  I made a list of "problems" to fix during the build.

So meanwhile I'll be skimming prints, magazines, and books for engines and will be dreaming.   The only thing I can say is that the "Wall Engine" by Roy Ozouf is growing on me.  It's a weird little engine and is in his "Three Elegant Oscillators" book which I immediately bought when kvom started the Coventry build.  It's beyond my skill level, but I'm ok to push to the next level!

Nicely built and presented Todd.  You are well on your way.
It is interesting how a list of things to do and tooling to make grows with every build ... all part of the fun.

Brilliant Todd, well done. What are the three elegant oscillators like? Are they bar stock?

Labeling it

Ok, one more minor update.  As I was making my walnut bases for my engines, including the base for the Pottymill Horizontal engine, I left room for little trophy plates to label the engines.  This was my fourth build so I decided it was time to order some.

I decided to go with trophykits.com.  Their web page looked easy to use and the prices are dirt cheap.   The first three engines had room for 1" wide by 4" long plates, and the Pottymill engine could use a much longer plate, but I went with 5".   I sent rather picky instructions that I'd like the fonts to be big and match across the four plates if possible, and asked if they could please right justify the year and left justify the engine name.  Well, damn they got it exactly right!   And for only $2 USD per plate.   It took 5 days, but here they are...spif!



They came with double stick tape already on the back, so here they are on my set of engines.



How cool is that?

Nice Todd!

If I could build 3 engines in one year I wouldn't know what to do! My projects are measured in years not months.

I have just read this thread from start to finish.

Very full and transparent description, and beautifully photographed, resulting in an immaculate engine.

I plan to have a go at this engine once I have a couple of oscillators under my belt. Only one thing, though - I don't share your love of maths so when it comes to the flywheel I'll be using dividing plates   ;)
