Sometimes small parts of the build turn into unexpected challenges. I am talking here of the small 7 inch by 5 inch curved aluminum door for the fuel tank cap for the gas tank in forward fuselage. Not sure how to make a securing device to keep the door shut. I do not need to lock it, but just keep it securely closed. I tried using roller catch which is used in cabinet hardware, but the aluminum door is at an angle, so the clip does not engage the rollers at the proper angle. Does any one have a simpler solution ?
Thanks

Rivet on a steel washer to the door and bond a neodymium magnet to the frame...

I bought one of those ( again cabinet hardware ) magnetic closers. But those again mount at an angle to the door on the inner wood RS-8 frame, so the small steel plate on the door is not making contact with the magnet.  Let me see if I can buy just the magnet and attach it to the RS-8 frame.

And about the spring hinge , I already have aluminum lightweight hinge installed at the top.

Thanks.

Nice idea but be careful where you mount the compass.

I have a spring loaded pin which is opened by a small pull cord. The cord just lies behind the instrument panel; it provides a positive fixing and no unsightly catch

A picture will surely help. I know many times it is not possible to post a picture as the plane is in a hangar many miles away. Thanks for chiming in.

I like his idea. Thx!


Why focus on proving how great you are, when you could focus on becoming better?...
