Mike's Completed Webster I/C Engine
« on: July 08, 2021, 01:00:06 AM »
All, I'm posting just a few high quality pix of my just completed Webster.  I'm very pleased with how it came out.  I'm also going to post links to two videos of it running in its final state.

Pix 1



Pix 2



Pix 3



Pix 4



Pix 5



Also 2 videos of the engine running.  First is the engine being started and run through its rpm range.  The idle speed is about 900 rpm and the highest rpm is about 2700 as measured with an optical tach.

The second video is the engine running at a constant speed while I moved the camera 360 degrees around the engine, just so all the details while running are visible.

Just a few comments on this engine and why I did certain things:

 - Why does the name plate show 2019?  Well, in a hopeless fit of optimism I had several name plates made since the local engraver gave me a discount on multiple plates.  And I'm too cheap to have it remade!! :Lol:

- The wooden base is thicker than I normally use and is a nice piece of yellow pine with a wax finish.  I wanted this to be a rugged piece of wood as I intend to use this engine as a test bed for fuel test, an ignition system that I want to try to build, and several carbs that I want to build and test.  A known working engine makes this process a LOT easier.

- I also did not permanently mount the fuel tank or the ignition system as I want them to be easily removable and changeable for testing other systems and possibly moving them to other engines.  Plus whenever i move this into the house for display, I don't want any gasoline in the engine at all. 

- There are a few things I learned and would have done differently.

--  I used Loctite 638 on the carb adapter and the exhaust.  This isn't adequate during longer runs due to temperature.  The carb adapter and muffler should have been threaded and/or I should have used Loctite 620.  Since there's no room for threads in the valve blocks, I'm going to switch to Loctite 620 and see how that work.

- - While I didn't pin the crankshaft gear, I should have changed the fixing method for the flywheel.  I wish I'd have used a key and keyways, as I did on the starter hub.  This would have made assembly and future repairs much easier.

--  I perhaps should have made removable bearing caps to retain the crankshaft bearings vs having to remove the engine frames for service. 

So, this really wraps this project up for me.  I'll post any results that I come up with regarding ignition systems or carburetors in separate threads.

So, at last, this is it!!   :cartwheel:

Enjoy!

Well done, Mike.  It’s been a great build to follow, and a lovely looking engine that runs well as the reward.

I look forward to hearing about the fuel and ignition systems experiments.
