Sorry guys-try me in late August! :-D

We need some unknown material for the fiberglass front end John K. is building. Hopefully, someone will know what it is we're looking for! Lol!

From John:  I need to find the product to use for the skirting material at the bottom of the body panels.  I need some of the black stuff that you have seen on other cars.  Probably about 3 inches wide maybe 2" would do,  and 3/16" to 1/4" thick.  Do you have any ideas?  I think they use a plastic material but maybe some stiff rubber would work.  I would like to know what works.  I know the front piece has to be stiff enough that the air would not blow it back but I would like it to have some flex in case or when it hits the salt.  It will be riveted to the bottom of the panels.
With sufficient thrust, pigs fly just fine. However, this is not necessarily a good idea. It is hard to be sure where they are going to land, and it could be dangerous sitting under them as they fly overhead. -- RFC 1925

Circle track stuff, the plastic used for body parts.

John, how about UHMW, it's like Teflon except it is a lot harder and stiffer. That's what these newer over head cam engines use for the wear strip at the chains.

Polypropylene, well I think that's how it's spelled. I used it as skirt material on my race car in the 80s when we still ran wing cars. Rivets will require large heads or washers.

Fordboy, you're right on at least some of your summations.

We did find that the flow increased by 'lengthening' the short side radius. Different valves helped, but ONLY after addressing the short side radius. The stock heads, and modified stock heads, flowed better than the race heads.

There will be a lot of work done in this area next winter, when we switch to turbos!

John K has been working feverishly on the front aero mods. Randy and John set and checked the alignment last weekend.

John is getting closer on the fiberglass work. He says the is still a slight difference side to side, but he's gaining on it!

Nice work, too! Way to go, John!

Guys,

Keep up the GREAT work! 
This is such a cool pic!

HELP! I need a m7 x .8 Tap!

Don is working like crazy to get the lifters done. We are using early Harley adjustors, and just found out the take a m7 x .8 Tap!

If anyone has one they are willing to sell, or knows where I can get one ASAP, it would be much appreciated!

You sure that is right? I can not find that size anywhere.

38flattie

Yep, it's right. I'm guessing Harley used that size to discourage everyone making copies of their work!

the only bastard size thread that I can think of for a Harley
would be 1/4-24 .
it was used for securing lifter blocks to the engine case
and on ( I think ) oil pump studs to the engine case.
also, maybe more apps to the engine .

1/4-24???????????? Sounds like they couldn't decide on a 1/4-20 or a 1/4-24 so they took the average between the two. I've never encountered a 1/4-24.
