Wow man. What a gift… judging a fastener by how a sled “looks”.

Without one of those, it’s a crap shoot regardless of what style bit you use. Why? Because fasteners have all kinds of bevel angles depending on whether they’re metric, SAE, UNC, UNF etc.wabene wrote: ↑Wed Jan 18, 2023 2:42 pmYou can just use a larger drill bit for the bevel as @Theme mentioned. I suggest the bevel bit pictured because it works really well in plastic, with a super clean cut. That is exactly what it is designed for. Plus the angle of the cut matches the bevel angle of the screw. Maybe five bucks. I would not use the other tools mentioned.
The problem with simply using a bigger standard drill bit for the head is that the bevel is almost certainly wrong. The head will not seat properly. More stress will occur where the material meets the top of the shank, which could lead to cracking. If the material is soft, it might just cam out over time and need to be tightened, retightened, tightened after that, and so on.
But hey, wtf do I know? Maybe I’m thinkun too much for Telemark Talk.
Everyone will go ahead and do what they want anyway. No sense using the right tools or even thinking about shit. That’s for amateurs. Life is more interesting when punctuated by failure. And it’s repeatable too, so the fun can last practically forever.
My post wasn’t to critique Theme’s sled… it was to highlight how the lowest common denominator gains constituency around here.
That part of the discussion started out on how to create a beveled hole. Reasonable suggestions followed. Then a solution — not to bevel the hole at all — was selected. Folks then went along.
There’s nothing particularly “fancy” about a counterbore bit, or a bevel gauge. If you bring the fastener to a reasonably stocked hardware store, you can get both for $10-20/euros.
Now I don’t pull a pulk, but I’d imagine it isn’t easier if the skid or shoe detaches tens of kilometres into the bush. So that’s a job you might want to do correctly.
Crazy talk eh? I’m just thinkun too hard again, I guess. Scaring folk with dangerous thoughts.
