Oversize hole for LP4-3 rivet

Good Morning!

Van's technical support has informed me that the recommended range of the hole size for this rivet is 0..129 - 0.136". I ended up with one being 0.140" and was wondering if there is a recommended larger rivet for this situation. My email to Van's asking this question has not been answered and I had no luck with the search function.

Thanks,

Tom

Where is the hole?

Depending on where it is, I would suggest stepping up to an LP4-4.

Sorry I didn't give much information as I rushed out the door this morning to the day job!

The hole location is the aft section of the horizontal stabilator skins that overlap and where the anti-servo hinges attach. Full disclosure is I messed up the overlap of the skins so I removed a bunch of rivets and was left with a few holes that were oversize.

Correction: Original rivet was LP4-3 not an LP3-4 (sorry for the mix-up). Therefore, what would be the next size blind rivet above the LP4-3 and where would I obtain them?

Thanks,

Tom

Tom,

Go to the Spruce Website at: http://www.aircraftspruce.com/catalog/hapages/cherrynrivet.php

Look at the Cherry BSP5 Series. You will have to drill out the holes to 5/32"

Good luck! Nobody will ever know but you!

While browsing on Spruce's website, see if you find the Oops Rivets. They are helpful for this purpose as they are just a little over-sized to compensate for enlarging the holes on drill out. I forgot what their real name is ... so you might have to google the correct term to find them on AS.

CR3243 uni head oversize uses .143-.146 hole. #27 is the usual bit used.
