hey im finnaly puting in my bags on bars and i was just wondering if you guys knew if it was safe to drill a hole threw them too put the lowere bolt threww / i know i could buy the bracket suicide makes but id rather not thanks
Are they round or square bars? I have seen a couple guys running the square lowers drill a hole and mount the bag that way... ie the white tacoma that Gravity Werx had at their booth in Blood Drag a few years ago.
Mike
they are sqyare bars from suicidedoors thanks and let me know
I did mine like that, but I put a lower bag plate on top of the link and welded it. Keeps the bag lower on the bar, and doesn't have an ugly ass bracket.
If you do, make sure the holes are directly through the center. If they are close to the sides it creates much larger stress concentrations near the outside of the drill whole by the side wall. It could cause the link bar to snap under load and twist. So using a drill press would be optimal to ensure a straight hole top to bottom and just center punch the spot where you want it. I would start with a steeper angled (90 degree) sharp tipped countersink bit with a slightly smaller diameter to start the holes exactly where you want them. Then use the regular high speed steel drill to drill the hole all the way through the bar.
Thats just how I would do it. There are many other ways that will do the job using what you have available. Be sure to ask more ???'s if you have any concerns, dont want to see you have to through away expensive link bars.
Oh and if possible you could cut a plate the same diameter as the bottom of the bag out of steel and weld it to the top of the link bars. This will help evenly distribute the changing load on the link bars and the metal bag mounts.
If you do weld to the link bars don't quench them in water or anything. The micro structure of the metal changes when you heat it up a lot like that and quenching will freeze the micro structure at this altered configuration making the metal harder but also more brittle. Allow the metal to just air cool so the micro structure can change mostly back to its original form. It will keep the metal strong but less likely to have a brittle fracture failure.
those bars are 2x2x1/4, im sure even if you drilled the hole 1/2" from edge and then welded a piece of plate solid to it, and THEN dumped a bag of ice on it it still wouldnt break....... if you were making these out of 14 ga tubing then you can break out the welding and metalworking textbooks and do a bunch of chemistry......
Yeah I did get a carried away there. Sorry for the confusing jargon.

True, but it sure is nice knowing that someone is using their brain.
The only thing that I would be concerned with would be de-burring the hole. A raw hole looks just like a crack to the bar and a crack will always propagate from an existing crack. So just de-burr your holes with a larger drill bit or something of that nature and you should be fine.
