Drilling Elevator Horns - Looking for drill bushing

I'm getting ready to drill my elevator horns and don't really feel like spending $20 for a bushing from Mcmaster Carr or chasing all over HD or some hobby shop to find something else that works.

If anyone is willing to part with their previously used drill bushing, I'd be happy to pass it on to the next guy who wants it to drill his elevator horns.

Not sure if the 8 is similar to the 7, but here is what I did on my 7. If you have a Lowes/HomeDepot/Tractor Supply nearby, you should be able to find this.

I used a barb connector from the plumbing section, don't recall what size I used. Wrapped one end in electrical tape so it would fit snug in the hole. I think it had a 1/8" I.D. that was a great drill guide.

I got the idea from somebody's build log, don't recall who offhand.

A piece of fuel vent line is 1/4 o.d. and will work just fine in this application. If you have your wing kit you already have plenty laying around.
