Well I'm about ready to get going.
Here is the sequence I plan on using:
1. Drill as required. OK that was easy;then
2. Scuff with Scotchbrite. This needs to be done before priming and the practice results I get show it does indeed deburr the holes also? Seems to be pretty safe as there is no risk of countersinking the holes a little. So why doesn't everyone do this? Doesn't it cut out a separate deburring step?;then
3. Dimple/countersink. I'm still a bit stuck on depth of countersinks. Especially regarding a recent thread on the subject. I can't get consistent measurements with depth so I'm just going to go for a flush rivet head when parts are together??;then
4. Prime. Not asking for what to use here but... Doesn't the thickness of the primer affect the dimple/countersink depth? Negligible? Is that why people prime before dimpling? Why do I see parts that only have the mating surfaces primed and not the whole part? Is there a reason to spend time taping off parts in order to leave areas (inside) not done? Weight? Save primer?
So fire away. I know there are lots of ways to git er done. Feel free to shoot holes in the above and educate me on a better way, or let me know what I'm missing.
Thanks, I appreciate your time.
