| Subject: | Side Cowl Pin Size... |
Dear Listers,
I'm happy to report that the cowling on the 'ol RV-8 is complete and came out very
nice. I was able to get the seams all around very nice and tight.
Here's my question. On the bottom cowl firewall pins and the top cowl firewall
pins, the plans call out undersized pins. These go in nicely and I've got no
complaints.
However, on the side pins that join the top and bottom cowling pieces, the plans
call out an AN257-P3 hinge and don't mention using an undersized pin. I am
able to get the side pins in and out with a drill but its a lot of work, especially
going in, and it just seems like this is going to wear out the hinges after
a while.
In the kit, I noticed that Van's shipped two different types of hinges in the three-foot
lengths required for the cowling sides. There are two, 3' long AN257-P3
pieces and two, 3' long <other kind of hinge> that seems to be steel instead
of aluminium like the AN257-P3. The pin inside of these steel hinges is about
2/3 the size of the pin in the AN257-P3 hinges. So, my logical thinking
lead me to think that you're suppose just use the pins from the steel hinges on
the sides for easier pin insertion/extraction. Am I reading this right? Or
is it just a coincidence that they sent the steel hinges? I don't know what
else to do with them.
Thanks!

Matt,
The smaller size hinge is for the gear leg fairings.
If the inside contour of the cowling is not uniform thickness where the sid
e hinges are attached, often very difficult to get the pin in and out as yo
u have discovered.
