Anyone used barrel type pivot pins for stop pins?

I'm trying to get back to some long put off projects, and need to make a couple folders. I don't have a surface grinder, or lathe and I'm finding that even though there are a lot more choices in hardware now than a few years ago, none of it fits together (I still managed to spend a fortune on the stuff too):confused:

I'm making frame locks again, and would rather not press fit the stop pins. I looked into the stepped pins that folks are selling now but there aren't any available that will work with a 3/16" blade that I have found. Standoffs are tricky as well, but I ordered oversized ground stock for the blade, .020" washers and should be able to lap .240" standoffs to fit.

So now I need to figure out a stop pin. It seems to me a that a hardened 3/16" pivot pin ought to work pretty well. Anyone see a problem with that? The heads wouldn't be flush, but they are domed, and it would allow for disassembly.
Anybody tried it?
 
most the time i just use hardened drill rod
i will be using folder pivots tho on some of the next blades im working on
 
Thanks butch
I did the drill rod thing in the past, and have had good results. I just don't want to go with a press fit on this, and there won't be any scales to cover it either.
Now I have to dig around and and see how many pivot pins I have, or if I have to order more hardware . UPS has been here 2 days in a row and I still have a belt order on the way , this knifemaking thing has gotten expensive again :eek:
 
yep i just got an order from mickley 1/8 3/16 and 1/4 pivots
razors, small, and larger folders
all for tween what orders i need to fill
 
You could use drill rod and drill blind holes from the inside of the handles. If you drill those holes first you can put a short piece in (short enough that the two slabs can touch) then clamp them together to drill your through holes.

Hey Butch, what size reamer are you using with your 3/16" pivots from Tracy? i just got into mine and they're oversize from .1875 reamer.i'm using a tapered reamer and biting my tounge while hopping on my left foot to get the right ream.

Also,3/16" pivots would work im sure,but might get expensive :)
 
ive found it easer to chuck the pivot into the mill (lather is not running yet) and light sand with 600 grit instead of fighting with a blade hole size
get the hole right and make the pivot fit as if you mess it up its just a few bucks not all the work that went into the blade
and like i said if you under size the pivot big deal get another one
 
I tried that first! but need to use the majority of the pin,so i cant chuck it up far enough for it to spin true.i need to get a new assortment of reamers i suppose.
 
i do one side then flip over test fitting a few times
that or thread a long screw in and chuck the screw in the mill/drill and do all the pivot at once maybe
yes i know im getto :)

That would be a nice professional way of doing things, but I've found that doesn't work out too well in my shop:foot:
I haven't found a satisfactory way to bore flat bottom holes with my little drill press so far, and don't really want to mess with grinding the ends of my stop pin to match the point of my drill bits. I've done it, but its no fun.

These are going to be basic working framelocks. 3/16" D2 blades, and .100" Ti frames. Trying for slim overall, but very sturdy (and maybe a bit lighter than the all stainless ones I've made in the past). So hiding pins and fasteners isn't a big priority.


As a side note, always check your stash before ordering material. I tried to dig out my micrometer tonight and found 9-3/16" stop pins (in 2 different styles), 8 pocket clips (2 small SS, 4 big SS, 1 Ti, 1 black coated), 2 thumbstuds, and some other random pieces and parts in the bottom of a drawer. So I didn't need half the hardware I bought for this job......but I'm all set if there's ever a shortage :D
