Dimpling Problems

[flyingtaran]

Hi All
Again I'm having newbie problems,
My dimples aren't going well, my dimples are not sitting flush inside each other when I cleko my vert stab together & the hole seems to be becoming elongated when I dimple.

Here is a picture, you can see that the light shines strangely off the side of the dimple.
Has anyone got any ideas??

Try to be careful and be at 90 degree vertical to surface with dimple die. If you are a little off, it can mildly change your dimple.

What are you using to dimple? Squeezer? Pneumatic squeezer? Make sure the dies are perpendicular to the flange.

I'm using a pneumatic squeezer on what i can reach with it and a DRDT-2 cframe for the skins, and i've been extra careful to make sure the die is perpendicular to the flange

[Caummisar]

Do you just MASH (that's Texan for push) down on the pneumatic squeezer or do you ease the ram up to the part being dimpled and ensure its 90 degrees before you set the dimple?

[flyingtaran]

I slowly squeeze the dimple

Don’t hold the part you’re dimpling to firmly. This will allow the part to align itself with the dimple dies before they set the dimple.

Well I had a lot of dimple issues of deflection
Around the dimples. The skins looked terrible.
I then bought a nice set of spring back dimples
From Clevland tool. Made all the difference in nice flat
Skins around the dimples.

Hi Taran,

Where in Sydney are you?

I am part of SAAA Chapter 11 (North West Sydney), why don't you get in touch, there are lots of people building RVs here in OZ that would be only too willing to lend a hand.

Cheers
Eddie

Thanks for the help guys,
I've ordered some new dies & ill see how they go,
And Eddie I'm down in saaa chapter 2 at Camden, and those guys seem to think it is the dies as well.

Thanks
