Need help.
Trying to install smoke nipples on my DA70 wiht JTech mufflers. The mufflers have a designated spot to drill out for the nipples, which I did. However, I quickly learned that aluminum doesn't braise.
Thought about tapping it and just using a grease fitting but grease fittings have a ball bearing and spring which would not be good in the long run for my Sullivan smoke pump.
So now I have drilled mufflers with now way to install the nipples.
Any advice? Big regional fly-in this weekend that I would really like to attend...with smoke
