How do I drill parallel holes into Schedule 40 pipe
I want to make a horizontal hanging bar mounted below my hanging garage cabinet for light duty use. The most common use case will probably be temporarily suspending my bike by its seat while I have the rear wheel off for service (and yes I am aware of the fact that hanging a bike with a "dropper post" from the seat is a big "no-no". My bike has a standard post)
Does my plan make sense so far or is there something obviously hare-brained about it? My plan is for occasional, temporary, light duty use to get things "out of the way". I want to drill radially through the PVC pipe on both ends and "capture" the pipe on the threaded rods with washers and nuts. Although not a high-precision job, I do want to have the through holes on either side of the pipe as close as possible to parallel with each other. I do not have a drill press (a neighbor may have one). I have a bench vise. How do I best go about drilling the holes so they end up parallel? I couldn't think of an easy-to-build jig. Much appreciate the help; I know there are some great tinkerers on this sub-forum. Thanks ![]() ![]() ![]()

Do you have a hand held drill? Buy this jig and the pipe will set in the 90 degree recess. Your biggest challenge will be marking the correct distances between the hole

With the pipe in the vice, a piece of wood with a "L" overhang could be used to scribe along the length.
There are probably other methods. I'd hang it directly from the wall (triangle all metal) if possible instead.

You’re over thinking this. If you look at the PVC pipe you have there is print all down one side of the pipe. So you already have a straight line to work with. Just clamp one end in your vice to where it looks like the print is straight up, hold the drill, perpendicular to it and drill away. It doesn’t have to be perfect. Just close enough will do. Repeat on the other end. The only measuring you should have to do would be how far in you want to go on either end. But you could probably eyeball that. I can’t imagine it would take more than a couple of minutes start to finish.

Lay pipe on bench or ground alongside a board or metal bar then use edge of bar to mark the whole length with a pencil to establish a straight parallel line. Mark your hole on each end and drill pilot holes with a very small drill bit being careful to keep centered on the marks. Then drill with correct size bit visually keeping bit straight. Or flip part over and make second marks exactly 180 degrees from first make. (one could also make a paper template to establish 180 degree by rolling and cutting a piece of paper to fit perfectly around tube, then fold paper in half to establish 1/2 circumference mark then put bac on tube and transfer the mark.
Lots of ways to do this simple task. Guys with lots of fab experience would simply do this satisfactorily in a minute or two by eye, but folks with less diy experience can use these other ways.

Get 4 45º bends or 4 eighth bends and make a dropped tube. Slide the ends into the channel. No drilling, no hardware. Or 4 90's; all will increase the distance of the tube to bottom of cabinet.
BTW, same fittings are used on all schedules so using Sch 80 won't deflect any. |

Not really what you are asking but Big Gator tools makes drill guides for that they work really nice.

Or you could just glue a T fitting on either end and not even have to worry about drilling holes.
