The store had 3 sizes of countersink, 1/2, 5/8, and 3/4. Which should I buy?
What size do you all have?
It seems to me the biggest one would work almost wherever the smaller ones do., and more, so I should buy the biggest one.
The exception would be, iiuc, when making furniture, etc. when one wants the hole for the screw head to be deep enough to put in a peg, to cover the screw. I've given up plans to make furniture, because I had plans to make my kids take the homemade stuff after I die, but I don't have any kids.
Are there other reasons to buy the smaller countersink?
The smallest one, 1/2, is big enough for today's purpose, but it won't be big enough if I have really big screws to work with. Now I'm, re-mounting a plastic arm to a swivel chair, a nice one that someone gave me because the arm was broken off. It has 4 or 5 adjustments, more than my other chairs, but it looks like it's for a secretary, rather than the boss. I want to look like the boss. It has a red seat and red back. No boss would sit on that, right? So I don't know what I'll do with it, but I still want to fix it.
OH, yeah, each arm is shaped sort of like an O or D, so the top is the armrest and the bottom is even with the seat, and screws to a metal plate coming out on each side. The armrests each have two holes and the plates have two holes at each end. But they are not the same distance apart, so only one screw can go in each armrest. I doubt if anyone replaced both armrests already, because the plate is just the right thickness for the slot in the armrest, so that means they either made it like this!!!
Thanks.
