Jerry,

If you need, I can look in the Home Despot in Athens to see if they have more?

Bill

 

Thanks. They have seven in Gainesville. I'm also stopping by Greater South Electric.
Next time you've got some free time come on up to Cleveland and I'll give you the grand tour.

Jerry

 

Will do... post-planning is next week, so I'll have LOTS of time soon!

 

What a great build! I'd go with the 2" EMT 90 degree bends and run them into one large around 3" EMT. Then I'd get a 3" header collector for the end and do a cutout pointing down off the 3" pipe so you can open the exhaust up if you feel like running it straight, or leave it closed to run through the muffler.
I'd also tilt the 90's back at around 45 degrees to give it a racey look!

 

A few idea's

Great pictures! Love that top one!

great thread....nice to see something different ....

 

Jerry, quite a few older cars use that convoluted flex pipe, and it can be made to look very good. But it is absolutely awful stuff to work with, and it rusts out and then leaks fairly readily. What you could do is build your pipes out of solid steel tubing, and slide the flex pipe over the top. You then get the appearance, but without all the other problems.

I rather fancy the second white car in the above pictures. Have six identical pipes leading into an expansion chamber with a conical "torpedo" nose, and a taper at the rear. Then have a smaller pipe going back, high over the back axle, terminating in a very prominent fish tail. And the whole thing would be painted mat back, just as in that picture.

 

Exhaust

Oh yeah, I've had experience with flex pipes on the old Healey 3000. You're right, they all leaked and rusted out. I thought about sliding flex over the pipes, but now I'm leaning toward wrapping them in that asbestos look-alike stuff. I had to go to three Home Depots to find enough pipes. My mock ups aren't very good. Note that the front tire in all the pictures is cranked all the way over. You can see there's no room for the exhaust to come straight down. The first picture shows number one pipe angled and the rest straight. In the second both front and rear pipes are angled and in number three picture all are angled back. I think the third setup looks best. In the last picture you'll see I added a 45 degree pipe which I think looks best of all except I'll need to take about 4 inches out of the pipes at the joints to get it the right height for the muffler. I think it looks Blitzen.

I like it Jerry.<r/> To my eye all the pipes absolutely must be parallel.
Get the front one right, to dodge the wheel, and make five mere exact clones of that one.

 

YES !

 

What is this???? Have any more photos?

 

Lots more pics in the aero engine thread.

 

I'm no good at free handing so I'll have to build a jig to weld the pipes together. That's the only way I can get them exact. I'll also probably hold off attaching a muffler since I'm dying to here the beast run! I'll try to video that and post it on youtube so you guys can hear it too. I've never posted a video but how hard can it be?

Picture #4 looks the best. I look forward to hearing it run.

 

Jerry,
Can't say why, but option #2 (front and rear pipes angled opposite directions) is very appealing with the individual cylinders! Give it one more check with all the lower ends equal distances apart. Maybe 75% of the distance at the cylinders? If you made the collector tube right, that might be the best looking one of all.

Can't go wrong with the Blitzen style, it looks kinda wide with those big cylinder spacings though...

 

OK! this is just too cool for words. I want to see more.

Loved the video of the one running.

Jerry,

I think you can lean them even further (keeping them parallel).

You might want to wait until you have a body on in, or at least in mind- might find a body line that you can match with the angle of the exhaust tubes!

Exhaust

I was making up a jig to weld every pipe the same when I discovered the elbows weren't uniform. I measured the pipes and cut them off equally. Then I put them in the jig and tacked them together. After that I bolted them to the engine and they turned out surprisingly uniform. Go figure. I can weld good but I can't weld pretty so I again enlisted my welding buddy to make the final welds. Now to concentrate on the crankup.

Lookin' gooooddd!

 

Final engine assembly

I had a few more engine parts to paint. There are two side covers, the distributor housing and also the compression release. The release operates by shifting the exhaust cam back (or is it forward?) Anyway, I think it holds the exhaust valves open. Then again it might hold them shut. In which case I guess it would be an engine brake (Jake brake?) I'll have to look closer before I put on the oil pan. I did the final clean on the oil pan and front cover which I then coated with Bull's Eye Shellac. Some of you might scoff at my low tech coating but I've become a real fan of Bull's Eye (made from the lowly Lac bug.) Check it out, you might like it. I'm no ecofreak but you can actually eat this stuff! Also check out the old repair on the pan. That was back when men were men and guys welded aluminum with a torch! Anybody do that now? Tomorrow I should be able to bolt the pan and front cover in place. That'll put me real close to crankup.

I forgot to say that I used muriatic acid to eat the galvanizing off the pipes. No blue/green glow and no choking. Except on the acid fumes. You can see the effect on the pipe near the flange.

I have been thinking about your V radiator desire. Some of the old racers I have seen with a V radiator had a shell over the top of the radiator that also went down the front in a very narrow strip. If you made up a shell like that you could hide two radiators behind it and save yourself the trouble of making a true V radiator. If you made the shell out of brass and fit the radiators right it might even look like one piece...

 

I've been giving a lot of thought to the radiator too. I calculated how many feet of copper tubing it would take to make a tube radiator and it was astronomical. I'm leaning toward some kind of material in the front with a lot of round holes (or square holes) in it and then behind it somewhere put a flat traditional radiator. I figure I'll make the shell and then figure out how to finish the thing off.

That radiator construction , ( hex on the end of round tubes), looks like the approach used on a radiator of recent, (but not sure how successful), one known as the "Heat Sponge"......

 

You can check my math but I figure a 30" X 30" radiator 3" thick using 1/4" tubes will have 120 X 120 X 3 = 43200" of tube or 3600' of tubing in it. 3600/50 ft roll = 73 rolls @ $27.00 = $1971.00 And that's just the core! Am I doing this wrong? I can buy a nice new radiator for way less.
