KR> Fuel tank pick up and vent

[John Martindale]

Given that 32mm is the diameter of the Rochester carb on just one cylinder
(3) bank on the stock car engine, my feeling is that a single 32mm carb
would be too small to feed both banks (6) especially at higher revs. What do
Aerocarb say?

Thanks for your input Joe,

I remember reading somewhere on WW site that the 32 would be ok for a stock 
corvair..snip.

Thanks for your input Joe,

I remember reading somewhere on WW site that the 32 would be ok for a stock 
corvair.
The carb came with a kr2s project I had purchased and if it doesn't work out 
I will
do something else.  Thanks for the heads up on the vent being near the 
exhaust
stream.  I will check that when I get the engine on but shouldn't be a 
problem.
That is a good note for the rest of us builders out there.

Thanks again,

Steven,I have many memory lapses, Is the 32 mm the recommended size - 
for some reason I thought it was the next size up, I run the 38 mm with 
pretty good success on a 3100 cc.Mine did not come out the bottom of the 
fuselage with the vent just to make sure that if fuel came out the vent it 
didn't get into the hot exhaust stream.For your consideration,Joe Horton

It is a 32mm aerocarb, 12 gallon RR fuel tank, stock cid corvair, and the 
vent is a 5/16" aluminum tube
under the fuselage about an inch bent into the air stream.

KR> Diehl Wing skins

[herbertsn...@aol.com]

Are you going with wet wings or fuel tanks in the wing?

KR> Re: Diehl Wing skins

[smwood]

Russ,
The Diehl plans call for putting the bottom skin on first then put on the 
top skins.  Before you do the top skin, put in the inspection ports in the 
bottom skins.  That's a lot easier to do at that stage.  If you are careful 
in cutting out the holes, you can use the cutout piece as a cover plate for 
the inspection hole.  I used a Dremel tool with tiny router bit and a router 
adapter taped to a hole cutting guide.  Lowes has all the parts.
You will need inspection holes big enough to get one hand and arm through. 
Put them everywhere there is a nut or bolt head or vent pipe for a fuel 
cell.  I have 26 openings on the bottom of my wings and everyone has a 
needed purpose.
Don't worry over the exact dimension of the airfoil shape of the ribs.  When 
you get them glued between the spars, you will have to cut them down as much 
as 1/4-inch to allow for the varying thickness of the Diehl skins.  Then you 
use lots of VE flox to fill the gaps.  When the top skin goes on, you can 
reach in through the inspection ports and make sure the flox is 
finger-filleted in all the joints.  That is especially important to close 
leaks on the blind side of the fuel cells.  (Been there, done that.)
You vary the gel time for the vinylester by adjusting the amount of catalyst 
you use.  The higher the temperature the faster it goes off.  The 
instruction ratio calls for 4 cc catalyst to 8 oz resin.  You can use 1 cc 
per 8 oz and it still works ok.  Do use a calibrated syringe for the 
catalyst.

Hi Russ,
 I used Dan's skins on my KR2 some years ago and was fortunate in having
met Dan at a gathering. I think I was the first to use them in the UK ,and
had no problems except that the rib cut out markings didn't correspond
somehow .
 I contacted Dan and he reassured me that my markings were not
accurate ( it was in the '90's and I've forgotten how exactly-but I'll look
up my notes if you can't get better advice).
 One thing I do remember is how fast vinylester goes off , so you have to
get a reliable pal and rehearse the procedure.
  I also had to open inspection panels in the lower skins to satisfy our
inspection authorities who would reinvent the wheel if it hadn't been made
in Birmingham!

Cheers,   Mac  ex  KR2 G-BVZJ

 Hi folks.  Could someone post the link to the corvair group, please?  
Thanks.
