Ideas That Work
C. L. Barker Engine Reconstruction Project
The Old Marine Engine Board or OME is a clearing house and meeting grounds for people with an interest in antique inboard marine engines. On OME, information on many, many engines is available and the members are willing to share there experiences and knowledge with those in need. It was on OME that a gentleman asked for information on a Barker single cylinder inboard engine. It was in terrible shape but mostly complete. This page is about the restoration, or reconstruction of this engine.
My goals are simple.
Here's how the whole project got started. Old Marine Engine Text
These pictures are very large. For those of us who live in little towns where JAWS 2 is still in the new releases section of the movie store, it'll take a while to download.

The Barker must have been a good runner to have so much wear and repair. I'm hopeful it'll 'bark' again!
The Barker and some other stuff is in the furnace as I write this. Tomorrow I'll post pictures after the first burn-out.

Just out of the furnace this morning from the first of what looks like will take three heats. Everything looks good, and with 2 hours work it's knocked apart.

After the second heat, we found a hole and a crack and needed to remove a part of the water jacket to gain access. The hard crusties in the bottom of the water jacket are nasty stuff. You can also really see the hole behind the drain plug. It sort of an argument against using bronze plugs, isn't it.

These are pictures of the welding in progress. It's not the Barker, but a small vertical Oil Field engine. The side was blown out, and the owner wanted it fixed as original. A patch was cast, and welded into the hole. The hole is about 6 inches by 3 inches and the patch went in very well. I'll post finished pictures tomorrow when it comes out of the heat. This engine is a one of a kind. At the same time, the Barker went for the 3rd heat and stress relief. These pictures are taken with the parts at temperature.

I thought it had been a while since I'd posted an update... I didn't realize it'd been over a year. Sorry about that. The Barker is shaping up nicely and the inside water jacket, the cracks in the combustion chamber and the hole where the plug was are all fixed. This process has taken some 8 heats and over a pound of welding rod!!
The next step is to fix the outer jacket parts and cast new parts that are missing from the water jacket. These are the parts we have from the original. We are aiming to have this at Calvert this year so folks can see it.
Starting to finish the welding. The old water jacket is back together and looks good. This is as far as we'll take it until we get the rest of the welding done. The next step is to cast the missing piece.
After the water jacket is fixed, we'll start figuring out the piston and get the crank bearings done.

I have to do better with my updates...
A lot has happened since the last update. The cylinder is finished and the new sleeve is in (Thanks JB). The crank is welded up and finished (Thanks Bob L). New bearings are done and slingers are finished. The piston is finished and we have started to work on the rod. Dad has been working on the igniter and water pump parts. The starting handle and timer adjustment eccentric is completed. The water pump strap is brazed up and ready for finishing. New stainless steel case bolts were made to 1/2 -12 thread just as original.
The main bearings have o-rings and shaft seals to try and keep the mess to a minimum while running. The aluminum piston has a 7/8 hardened pin and will float in the piston. It took about 3 hours to hog out the inside and about 2 to machine the deflector on top.

The Igniter trip and water pump are done

Getting everything ready and bolted down to the test stand.

Connecting Rod is done! It needs some fine tuning, but looks like it'll work!
It Runs!!! Here's a short movie with no sound. It'll start by just flicking the igniter trip on compression. Pretty cool really. Click on the messed up picture below and the movie will open in a new window. I'll fix it later...
More to come...
