Anyone know a source for the stainless hinge pins besides Vans?  I don't 

understand why they don't provide enough for the side hinges between the 

top and bottom cowl.  Page 47-8 says they are available from the 

accessories catalog.  I'd think they are more than just accessories.  I 

understand that they weld on a retainer for these "accessories", but one 

would think that it would be supplied in the kit.

Sean,



I purchased hinge pin material from ACS - this may be the right number but

you need to check: MS20253-P2-7200 HINGE PIN SS 03-49000.  I see no

advantage to stainless steel over the standard steel pins.



I got (2) 6' lengths as I install the cowl side pins from inside the

cockpit.  The pins run through a piece of 1/4" aluminum tubing on the cabin

side of the firewall that acts as a conduit.  I took a 3/16" round head

rivet and drilled a 1/16" hole through the center, then countersunk the

shank end, cut off the head, and JB welded the rivet into one end of the

1/4" tubing (countersunk part to the inside so the pin is directed into the

1/16" hole).  A 3/16" hole is drilled into the firewall such that the rivet

shank pokes through 1/4" or so, in a spot such that the pin is directed into

the first eyelet on the cowl.



This is really a lot simpler than it sounds.  The end result is with a few

AN fittings you have lockable side pins that don't poke through the front of

the cowl.

Thanks Carl.



I assumed it was "required" to replace them with the part mentioned in 

the plans, but I am now seeing that is not the case.



I shamelessly stole the pin retainer from Mike 

(http://www.azcloudflyer.com/finish/IMG_0298.jpg).  And it seems the 

pins that come with the hinges will be fine.

Re conduit for cabin side entry of side cowl hinges, rather than use 1/4 inch ally pipe, if you go to your local auto brake place you'll be able to purchase steel brake pipe that the side pins are a neat fit in. Then it's only a matter of drilling a hole in the firewall and fwd fuse bulkhead F-1002-R that is a neat fit for the steel pipe and lines up with the side cowl hinges, bond with bondo or epoxy. I've kept mine straight just below the vents but you can bend the pipe to any location and the pin will happily follow. Epoxy a rivit into the last forward piano hinge, top or bottom to stop the pin from making friends with your fan.  Cheers from Western Australia.

You will be very happy that you bought the pins from Van's if you do. The welded on tab makes it much easier to remove the pins and keeps them very securely. Just using an eyelet to hold the tip of the pin is not nearly as nice, IMHO.



YMMV

Amen to that Jesse!  I had just the hing section for a long long

time, and while it did work, eventually the eyelet widens and the

pin can start to move and then the wear happens faster yet.

I did the JB weld thing for a while to hold it on, and that worked

ok for a while but soon one of them broke free and then I had to

re-glue it. Finally I got ticked off enough that I did it better.

I bought new pins, and a section of stainless hinge, and silver

soldered them together. Yes, Van's does sell a pre-made pin, but

by this point I was irritated and knew I could do a better job

if I took the time.  Wish I would have had Van's pins right from

the start.  Actually, if I could do it all over again, I'd

make mine look like Sean's where the pins get hidden by an

oval shaped RV-10 logo. That to me trims it out perfectly.

By design they are supposed to be recessed and flushed. Here is a link to the instructions.
