You work fast, looks great.
You should start your own thread on this build so the two do not get all convoluted.
Ken, I had considered it. but with my work load I dont know how diligently I can post updates as I go. but I suppose it would be best, so I dont tread on Steve's thread. so maybe I will.
is the bore spacing the same as the other demon
and bolt pattern
each valve gets a port???????
edit
never mind saw the new thread with my answers
Yes I started my own thread so I Don't steal Steve's thunder
heres the link unless I didnt do it right

I made all my tank fittings for the radiator. Will have to wait to assemble. I bought a torch but have not had a chance to get the bottles filled.

Steve,
Have tried to find the diameter of this little leg that the red arrow points too, not the crank Journal.
thanks
Ken
ken its .50 dia thru for the crank bearings and .575 dia .248 deep for the gear clearance
Thanks !
Ken
no problem
Dang my hide, now I see that dimension on the drawing :(
they are easy to miss. not that its drawn poorly there's just loads of info there.
Hey everybody.
I found a few minutes today and worked on the radiator. The oxy/acy is alot hotter than the mapp gas. Took me a while to get used to the extra heat. I used the silver solder to install the fittings into the tanks. Then the end plates were soldered onto the tubes on both ends of the core. The fins were soldered onto the 2 outer most tubes.
http://i770.photobucket.com/albums/x.../DSCN1999s.jpg
After all that the fins were evened up on the belt sander and the tubes were milled down in the mill using a 1/8 inch endmill and taking very light cuts.

If you purchased the plans you are probably wondering why the tanks have so many pockets. The second pocket is the pocket that the end plate sits in. The first pocket forms a reservoir for the solder to bead into.
http://i770.photobucket.com/albums/x.../DSCN2006s.jpg
The tanks are both installed the same way.

Then the top and bottom channels are made and soldered to the tanks on the ends.

Then I sand blasted the entire thing to clean it up. Now I need to make the mounting posts and clips.

Stunning work. Thanks for sharing it.
Steve,
What is the engine size..?? just that radiator looks a bit on the small side to me.
Jeff
Fan is done!!
http://i770.photobucket.com/albums/x.../DSCN2020s.jpg
Didn't like the fan so I made another

Looks twice as good :D
yes I like the new fan better as well. Steve do you have any pics of how you made the blower rotors? I am curious to see how you did them. oh and the valve covers look pretty nice all shiny and polished.
nice looking radiator. aside from it being small youd think it came from the auto parts store.
I was just being a smart arse on the twice as good since one had 4 bladed and the new 8 but really, it does look so much better. The radiator, that looks like it was/would be a real stinker to make.
The internet is a marvelous thing, with out it I would have never been privy to this effort, thanks for sharing your work Steve.
Cannot wait to hear it run, with Craigs Demon 1.5 V8 it'll be double exciting, I'm serious, cannot wait to hear them run.
Getting closer!
I broke a sparkplug so I need to make a few more then it on to the exhaust pipes.

If anybody is interested I am making the plans available for the blower conversion. They will be $25USD via Paypal to [email protected]
They are 27 pages that include the blower, intake manifold, all linkage parts, parts list, ect.
I have started installing the ignition system. The hall sensor is superglued in the distributor body. The magnets are pressed into the disk and loc-tite is also used. I put some temperary wires on the ignition and hooked up one of the #8-40 plugs. I gapped the plug at .022. All seems to be good so far.
I use one of Roy Sholls WYSWYG ignitions. I also use his hall sensor to trigger the board and his 10KV wire.

Here is a short video of the test. I know how you guy's like video!!!

I'm in a bit of a lazy mood today but I did go out and make some test pieces to try to tame the ignition wires. I think I have figured out what I need so I'm going to redo the pieces and cut out a new set.

Finally got the final coats on the box over the last few days.

Seeing that ignition system fire off has me pumped! I have been spending all my free time modeling the engine so I can get started cutting parts. The plans are great! Looks like your engines are getting very close to being ready to fire up! How soon do you think? Also, what fuel are you planning to run in these engines?
I wonder what would have to be changed to run a nitro/alcohol mix?
OK I'll bite, whats the WD-40 for? lubrication? or some other function?
carby jets if it uses jets or crank open the needle valve otherwise,something like 4-6 times the mount of alcohol fuel to create the same energy and a good clean out internally every time you run the engine. Nitro turns into acid andbites the internal steelworks something shocking if left to sit.
Im with you I would sacrifice a little smoke and know its getting some lube.
I have made the LAST gasket. The bellhousing adapter has a water passage in it so it needs a gasket. I made the last fixture but I couldn't use the part to cut the outside shape because the gasket needs to follow the shape of the oil pan. I made the fixture duel sided with a plate in the shape of the gasket.
http://i770.photobucket.com/albums/x.../DSCN2047s.jpg
As always a piece of material is sandwiched between both plates.
http://i770.photobucket.com/albums/x.../DSCN2050s.jpg
The bolt holes are run thru with a drill bit and the big hole is cut out with a razor blade. The gasket is removed and this is what i had.
http://i770.photobucket.com/albums/x.../DSCN2052s.jpg
The piece is then moved to the right side of the fixture and sandwiched again.

The outer shape is cut with a razor blade and the gasket is ready to be installed.

Steve,
Nice gasket fixture and makes a perfect looking gasket.
What type is the gasket material?
