Hi All,
Got the exhaust push rod and support done, cut rocker out of 10mm round bar(don't have 1/4" square), and made up the exhaust with a twist "plans said Brass--Because its sexy!!!"
Material I am waiting on ended up being sent to the other side of the country, maybe here this week sometime.

Cheers

Your ribbed exhaust is far sexier than mine. Looks like it may have a bit of French influence----

My brothers around the world, I am asking for progress reports. It is 3 weeks until Christmas. Currently, we have two running Rupnow Vertical engines, one being mine, the other belonging to David Lloyd. Although I am forging ahead on other projects, I haven't forgotten any of you. I know that Herbie is right on the verge of a running engine if he can get his valves sorted out, but I lose track of where you other guys are on your builds. Please give me a heads up about where you are on your builds, and good luck to all of you.----Brian

I have restarted working on mine yesterday and got the carb completed and the cylinder head started. I won't have crank bearings for at least a week and I need to source some cast iron for the cylinder that fits in my meagre budget. I doubt mine will be running by Christmas after all.

Cogsy,
Try this for the cast iron.

Hi All,
Got the con rod done, added 2mm corner rounding, was going to I beam it as well, but I don't think it needs it. Parcel for the alloy has ended up being sent to the other side of the country, may see it this week I hope.

Cheers

Well, I have been busy making a valveseat cutter, new valve cage, valve and Spring. Finally got no leakage at all using this little test pad I made up.
Now to assemble the engine again and fire it up

 

[Ghosty]

Hi All,
Con rod after first polish.

Cheers

 

[Ghosty]

Woo Hoo, My wayward parcel arrived, now to start with the chunky bits.

Ghosty--Be aware--If the center to center of the gears you are using is different than the gears I use, it will affect the position of the thru hole for the camshaft in that biggest lump of aluminum.

Brian, Thanks, All ready worked out, used the same gears in another build. I need 24mm(0.9449) spacing, which if I remember is only just larger than your gears.

Okay, 7 or 8 thou isn't going to matter.

Thanks Bruce,

DavidLloyd,

 

[Brian Rupnow]

Beauty, David Lloyd!!!

 

[Ghosty]

David Lloyd, What a beauty, runs very well, congrats.
Brian, The countersink in the cyl mount plate bolts is only that depth for the cap head screws. If different headed screws are used the depth could be altered to suite?

I know what I will be doing today.

Cheers
Andrew

 

[Brian Rupnow]

Just make the counterbore equal to the head height of the socket head cap screw that you are using plus about .005". A countersink is for a flat-head capscrew. A counterbore is for a socket head capscrew.---Brian

Brian, Thanks, brain still a little slow after all the marking out.
