What is the best way to make the holes for the screws? I've been told that drilling it would weaken the helmet so what other alternatives are there? Cheers, Al. IP: 94.0.253.144

My memory is that it didn't take much effort at all, I wasn't thrashing away with a hammer action bit for 15 minutes. I await hand wringing replies......

And there was me with my masonry bits on standby too. I guess the helmet would be out of warranty now anyway. I'll just drill it. Thanks! IP: 94.0.253.144

My last CS Protex had 17 "non factory" holes drilled in it! Mine certainly isn't the only one to be abused like that. Most cavers and mine explorers tend to modify their helmets to a greater or lesser extent; if it was a problem I am sure there would be regular reports of helmets failing. Only thing I would say: When attaching the bracket make sure there are no pointy bits on the inside of the headshell. IP: 86.136.235.33

I can think of only one recreational lamp, plus of course the miners lamps, that fit on a bracket. Most decent lamps bolt direct, wondering what this is about, unless choosing a lamp that needs you to buy a bracket as well has some advantage I miss. -- "How people get on with these things as a mobile device I cannot begin to imagine, but it certainly explains a lot about peoples behaviour."

I know it's not the best piece of kit but it has never let me down and still kicks out a good light for 7 or 8 hours. I've never felt the urge to replace it yet. IP: 94.0.253.144

Lamps that can be quickly detached from a helmet do have some advantages. IP: 86.180.202.212

It comes about because of testing. When the helmets are tested, the holes aren't there so you shouldn't add them IF you want the helmet to be still within test conditions. Obviously non of us care about that. However, in the world of work, some companies will not allow even the addition of stickers to helmets as it technically invalidates the helmets approval.

Years ago a builders merchants I called at were selling steel tape rules at a daft giveaway price, but with a large warning notice. Apparently they had been made with the first foot from the end as a "measuring foot" as it was described, so the count of feet etc started again. Result was if say a room was measured from the tape end and a reading taken, it would be a foot short. I told them that I would not take one for nothing and that they needed to be destroyed. The bloody daftest thing I have ever seen. -- "How people get on with these things as a mobile device I cannot begin to imagine, but it certainly explains a lot about peoples behaviour."

When I worked in a woodworking shop we would usually measure using a start point on the tape rather than the end if a precise measurement was needed - the hook thing on the end of tapes often gets a bit banged up and bent and also slides by 1mm or so to accommodate internal and external measurements and those slots can become worn. Probably too much potential for confusion though overall. Incidentally I can't believe that Blackadder quote has been up for nearly half a day without anyone weighing in with the whole 'Vikings didn't actually have horns on their helmets' thing........

Petzl do allow stickers on their Vertex Best helmets, as long as it's on the two smooth panels front and back, so I took the opportunity to fill those spaces with 3M reflective tape, matching the helmet colour so they're not too obvious in dull light. Works a treat, and I haven't been run over by any large plant machinery yet. IP: 81.174.241.13
