I have cut my metal baffles to the proper height but I can not find where

the dimension is given for the rubber flex portion.  How much should I

leave above the metal portion. How much extra should be present after the

rubber touches the cowling.  I've seen some pix of some that had lots of

material such that the rubber was sagging  even when the cowl was off. 

Just a bit confused and need some help---HELP!

Jim,

If I remember correctly I started out with four inches on the baffle seals 

on my O-360/6A. The seals overlap the metal by about one inch. From there I 

adjusted the width of the seals if required to get the best fit to the cowl. 

As you have observed you do not want too much seal material so that it hangs 

away from the cowl.

I posted this same question on the Vans Airforce forum a few days ago.  The

responses I got indicated the seal material should stick up about 1.5

inches upon completion.  Im not passing judgement either way, but 1.5

inches is quite a bit different than 4 inches.



 Dale, could you tell us how far your seal extended above the baffles

AFTER  final trimming?  No sense in wasting more material than necessary,

and from what I hear, its not like Van's gives you a surplus to work with.



thanks,

On my RV-6A, O-360 the baffle material extends up about 1 & 1/8 inch on the

sides and front and 1.5 inches on the back.

Sorry guys, I can't give you a final after triming dimension as mine is not 

the same in all location. 4 inches was the STARTING dimension. As I said, 

the rubber seals overlap the metal baffle by about  1 inch which leaves 3 

inches. From there I trimed to fit. For example, in the corners near the 

firewall I used waxed lacing cord to "sew" the corners together after 

forming a curve in the corner of the baffle seals to meet the cowl. Here I 

probably used the full three inches remaining. In other places, such as 

around the front ramps in the top cowl, they are less then 1.5 inches.I did 

do more triming after the flying for a few hours when I could see better how 

the seals were seating against the cowl.

You can start out with less than 4 inches. You just have less to play with 

in the final fit..

I did use Van's baffle kit and had material remaining when I was finished.

I've done 3 sets of baffles (RV-4, RV-7, RV-10) cut them all 3" wide

with about 1.25" below the baffle top and 1.75" above the baffle top.

If you go much thicker, I can't imagine you'd have enough material.

Van's has it calculated down to the square inch it seems.....
