In this photo you can see that the studs have all been made and installed for mounting the valve chest and also the gasket has been cut...
We are getting closer to putting the piston in, so the last thing to complete is the brasses. Photo #1 shows the brasses ready to come out of the lathe. The radius have been turned and the final sanding all completed. Photo #2 shows the brasses all completed and ready for installation. If you look close you can see the oil grooves, put in with a dremel tool, and also the oil hole has been drilled and tapped...
This photo shows what the connecting rod and brasses will look like all assembled. Now to get the piston in...
Well with a little bit of elbow grease and a lot of padding, the piston, connecting rod, and the brasses are all assembled in the engine. Everything went together real good and is functioning properly. Joe Sykes who bored the cylinder and built up the piston, and made rings, did a great job...
In these next 4 photos you will see me getting help from 4 good friends to get the Bovaird ready for May 20th, which I am going to be having a gas up and pig roast. There is one fellow not shown, his name is Dale, he helped me get the piston and connecting rod assembled into the engine. Photo #1 shows Ron Polle using the sand blaster cleaning a cover plate for the cylinder. Photo #2 shows Stiles Bradley running the drill press. Photo #3 shows Dave Yorks clean up some oilers on the Swan getting it ready for the gas up. Photo #4 shows Ron putting the cover plate on the cylinder. Thanks a lot guys for all your help!...
Photo #1 shows Ron wire brushing the internal threads on an elbow for the check valve. Photo #2 shows Dave cleaning and adjusting more oilers...
In these next three photos you can see the valve chest and misc. parts going onto the engine. Also the hot tube chimney and exhaust pipe. The unpainted part in photo #2 is the check valve which mounts on the top of the valve chest. The third photo shows the rocker arm and pivot all in place. It wont be long now...
THE 10 HP BOVAIRD & SEYFANG SINGLE VALVE COMES TO LIFE!
In Photo #1 you can see the set up I use for turning the engine over. I like to use the tractor because before you turn the gas on you can watch everything and make sure all is right before starting her. Things are usually quite stiff when you just get the engine together for the first time and the tractor makes it turn over easy. Photo #2, the engine is running! Man what a feeling to see her run under her own power. Its Mothers Day, May 14th. Thanks again to everyone for all there help, both during the entire restoration and in the last few days. In photo #3 I have run the engine a few times and now have water hooked up to it. She can run for quite awhile now and things can get broke in. What a great feeling it is seeing her going for the first time in who knows how long...
The following 3 photos are of the 10 HP Bovaird & Seyfang all completed. I hate to say the engine is all completed because there are always those little things that keep popping up but like any engine restoration, the more you run it the more it gets broken in and the more the owner learns about it. This has really been a great project and a fun one. I plan on taking the 10 HP B&S around to engine shows during the 2001 season. Hope that you all have enjoyed following the restoration project as much as I have had working on it. Thank for following the restoration...
Below is a photo of the 10 HP Bovaird & Seyfang engine completed and running at the Coolspring Power Museum's October 2000 fall show...
For those interested I have a 4 hour long video of the entire restoration of the 10 HP Bovaird & Seyfang. The video includes retrieving the engine and everything from fabricating parts, machining the parts, pouring babbitt, and then the first running of the engine. Everything you have seen on this webpage of the 10 HP B&S restoration is on this video and more. Please contact me using the e-mail address below if your are interested in getting a copy of the video. Thank you.
