Default Dimpling

Hey All,

First post here, looking forward to starting an RV-8 build next month. Should be picking up wing and tail kits soon.

I'm organizing, planning, gathering tools, etc. I built a Sonex tail kit before deciding that the Sonex was too small and it's worth it to move up to what I really want.

My current question has to do with dimpling. Sonex sells a dimple die set to be used with a pop rivet puller. I flush riveted all external rivets on the Sonex tail using this dimple die set and found it to be very quick and easy. Is there any reason that I could not dimple this way for the RV? Obviously, I would need a different dimple die set (100 deg solid rivets vs 120 deg pop rivets). Is there a source for 100 deg dimple dies to use with a pop rivet puller?

Any other thoughts on this approach?

Thanks,
Scott

Before Mike gets in, let me say welcome!
An 8 requires a lot of dimpling. Either a C frame or a DRDT-2 will be quicker and produce better results than a pull-die. But there are a few places where the pull-dimpler works and the others don't. IMHO in skilled hands the C frame may produce slightly better results; the DRDT-2 is easier to use.

Yes there are dimple dies for blind rivet pullers for both 3/32 and 1/8 rivets and I recommend getting at least a set of the 3/32 ones. However, using pulled dimple dies are waaaayyyyyy slower than say a c-frame ( or in my case a DRDT-2 ) or putting dies in a manual/pneumatic rivet squeezer. I just can't imagine dimpling an entire RV using the pulled dies.

Not sure what thickness skin the sonex' use, but I've not had satisfactory results with a pop rivet dimpler on greater than .020 skins. On my mustang, .032 rules the day and the puller will make a dent, but not deep dimples required for -3 & -4 rivets. Only a c-frame or squeezer will do the job with the standard spring back dimple dies. OR if youre really old school, banging a 426 rivet into the skins backed up by a female die made of a block of steel.....

I know of one fairly famous DAR who claims that all of his dimpling has been done with the pop-rivet puller. YMMV!

I prefer my pnuematic squeezer in concert with the C-frame for deeper dimpling. But I do have a set of pop-rivet dimple dies for occasional spots.

I have done the vast amount of the work on my -7 alone, and the DRDT-2 and a pneumatic squeezer have been a great help. I am a believer.

Thanks for the tips and welcome, everyone. Arnie, I'm in Seattle, btw.

I got good results dimpling up to 0.032 for the Sonex, but the 100 deg dimple would be a little deeper and more difficult. I'm going ahead and getting a c frame, but I'll experiment with the pop rivet style as well.

Do any of the usual tool vendors (Avery, etc) sell them?

Thanks again,
Scott

I picked up a Cframe and Pneumatic squeezer from Cleaveland Tools. Struggled with the Cframe until I made a table for it. Now I can rock through dimples using the squeezer and Cframe.

Yes. Avery, Clevelant and others sell sets.
