Question: Are you guy's drilling parralell with the top pipe, or at a 90 to the angle?
So, on your top pipe which is angled where you drill..... are your 8 holes round or eliptical ? Did I say that right?
It's hard enough to keep the bit from walking when doing perpendicular to the end plate. I don't know how anybody could go parallel with the pipe itself. Maybe if you drilled smaller pilot holes (as you really should) it may be possible. So, I had to go perpendicular to the plate.. Of course this is only an issue on the top pipe.
I pre-tapped it... and even drilled little pilot holes and still couldn't hold a straight line with a two handed drill. I went with the angle attempt. When it was all said and done... It looked just like the rest.
If anyone else is attempting this... I'd do the angle attempt and avoid catching or messing up! :bigthumbsup:
