Then I'd add the additional step of taking a bit of rod/screwdriver shaft at nearly the same diameter...leverage th rod in the hole so it bends the alu outward at the forward side and inward at the aft side. Then use a round file to put final deburring on all the edges.
Thanks Guys, i followed this method and got pretty great results.
I was originally told i could bend out the hole a little with a #2 screwdriver, but was cautioned against it by an aluminum welder. It was stated the better the quality the alum.... the more chance of it snapping/or cracking and i was not willing to wait another 4 weeks to get another pole... so i did not attempt to dimple (bend) the hole.
