Accessing a needle valve through a balsa cowl
 

This is my first all-balsa cowl (2nd plane). I was wondering how to access the needle valve on a Saito 100? Bent wire to the set screw on the end of the valve??? Should I lock it in somehow? Lock-tight? Anyone have any tips/tricks to alight the hole perfectly through the cowl? Any insights would be appreciated.:eek:

Thanks in advance.

Yes, just use some music wire as and extension for the needle valve. There is a small set screw in the needle valve knob that you can use to set the extension with.

I have used a piece of sullivan yellow inner pushrod just long enough to exit the cowl 3/8-1/2 inch. If you use a short piece of 2-56 rod inserted into the end of the needle valve and screwed or ca'd into the end of the rod you will have a flexible and light weight needle valve extension. It is flexible enough that I do not even have to remove it to remove the cowl and can be fished back out the small hole when I replace the cowl. The hole in the cowl can be off quite a bit and the flexible extension will still work fine.

I thought that was the way to do it...
