ROPS Tubing: Drilling Holes

[Midniteoyl]

If the dealer lost, I dont see how he could have actually billed the storage fees..

I better go check my drill bits
I tried to drill a hole thru the very top to mount a light fixture
The hardest metal I have ever tried to drill thru
I gave up------ I have tie straps holding my lights on top- UGLY

Try cobalt bits and cutting oil. Go slow speed.

It was bugging me so I gave it another shot last nite/started out with very small bit- bet I used 6 bits until I got it up to a 3/8 hole---- whew ! Tough metal !

mine drilled easily, 3/16" for wire clips.
Theres a new thread on here about a Kubota dealer that drilled a rops to add lights.

If you don't make chips with the drill bit fast enough, the heat goes into the tube steel, and not the chips, causing the tube steel to air harden. This happened to me while drilling holes to bolt hooks to my loader bucket. I'm not a machinist, but there is an optimum combination of "feeds & speeds" that will avoid this. Also, dull drill points will almost insure that your work piece will harden as you drill. Sharp bits are cool bits.

Your first statement makes no sense.

Of course it does.

Drill one hole in the center (any of the four sides).

Ok, it's in the center of the beam structure when viewed from that direction.
Ok, now swing your view point around 90 degrees and view your beam structure.
Voila! It is now in the 'edge' of your beam structure.

So depending on the actual force placed upon the beam structure, it is either on the center face or the side 'edge'.

Center and edge is dependent on the force applied in this discussion.

One of my customers is a machinist and he gave me a coffee can of small short cnc bits that were used. These little boogers do a great job starting holes wish I had some of these in larger sizes.

The hole is still at the center of the tubing...viewing it from 90 degrees doesn't move the hole from the center of the ROPS tubing...but rather then straight on, you're just viewing the hole's opening from the side. Matter of perspective...

A small hole is probably not going to hurt anything but why risk it, your life could depend on the ROPS. I think there are better ways to attach stuff to the ROPS than drilling.
