I read a while back that the marine
industry had a standard for track. Maybe they just meant T-track. Or, maybe it was just here in the US. It stated that track would use 4" hole spacing with specific size holes for specific sized tracks. I don't remember where I read the info but I was pleased.
Well, I just picked up a new main sheet traveler made by Lewmar
. The hole spacing is 3-15/16" (100 mm) with .354" (9 mm) holes. That's not so bad But the counter sink in the hole's is 85º. Most counter sinks for standard industry is 81º and 100º for aircraft.
So, where in the H*** is the average Joe suppose to find SS fasteners with a 85º head
here in the US of A. They could at least supply the faseners with the track if they are going to have there own standard.
And then when you call them on the phone
they get all in a huff.
Fortunately, I'm a Machinist and I'll be able to re-machine the heads on the few fasteners I need.
That's it, my rant of the day..............................._/)
