Opinions re Drill Holes into My Frame?

I got a pvc/flyrod tube holder from Riverboatworks in mounts to the front to back pipes on my NRS frame.......but it mounts by drilling a hole in the frame (not through and through, but one hole to then tap and put a stainless bolt into the forward and one towards the rear of the frame).....I mostly fish and do occassional overnight trips with the 14' Hyside boat.....only occassional class IV, mostly III and less.........anyway, anyone have thoughts/experience/opinions about screwing up the frame or weakness or risk of doing this, by drilling into the frame?.........after seeing this attachment, I have also wondered about this approach to attaching a "siderail" to oneside of my frame (bolts down to a couple of the cross member pipes to attach a plywood lane).......I don't want to go overboard with "swisscheesing" my frame....any thoughts? thanks, Chet

I wouldn't drill my raft frame, I'd add a piece and drill that. You could add a speedrail T, or even a slip T (like the speedrail umbrella holder, it comes apart for easy removal and install, I think Clavey sells those) and a short piece of pipe and drill that.

I was very interested in those mounts, but I ended up buying a piece of PVC and making my own rod holder. ~$15 It uses straps to attach. No drilling required. If you are uncomfortable with the mount, either try adding a piece to mount it to the frame or return it for store credit.

A couple small holes in your frame aren't of any real consequence. All the suggestions for alternative methods above are good, but go with what's going to be the most convenient and useful for you. If thats drilling two holes in your frame and tapping them - just do it. I have holes in my frame tubing for pins that hold the alignment of my seat and critical junctions of the frame are pinned through as well.

The more important thing is making sure that your holes are properly aligned. You mentioned tapping for screws so you need to know what tolerance you have and make sure that you are within that tolerance when you drill the holes. A drill press and a jig will go a long way - a vertical hole in a round pipe is almost impossible to freehand.

Seems it would depend on if it was a smaller diameter welded frame or a larger diameter DRE type frame with speed fittings. A welded frame might not have anywhere for water to get inside the tubing and you would not want to create a hole for water to enter. The larger diameter non welded frames have so many holes for fittings, screws and pins that a couple more would not matter.

My DRE frame has holes at the low point to drain.

Rich is right about the about the size of the hole compared to the diameter of the material. I remember there is an aircraft spec that deals with it..... but I can't find it.
It is something like a hole radius should be no more than 20% of the diameter of the pipe.......but don't quote me on that. Holes do not create stress.....they are used to relieve stress at the end of a crack to keep them from spreading. You are also refilling the hole you created by putting a bolt back into it. an past aircraft inspector and mechanic...... don't see a problem with the mounting method Ray suggests. Strapping it on does sound a lot easier..... so it depends on how permanent you want to make it.

A couple of 1/4" holes aren't going to make a large difference.

I would use a couple self taping screws and put them back in the holes when I took the rack off.
