My First

You may have to run the bit through the scale's holes a few times - sort of honing them out. It works for me.

Just checked, the rod I got for the pins is... 3/16 x5"(brass).. sooo if I'm looking at this chart that would be a.... 12?

actually, just looked. #12 seems hard to find. #11 is seems more common and available....

Looks like it will take until friday to get #11 bits in. Looks like I will be sanding down the rod.... :-(

Sometimes I m lost with your USA 3/4 and 155/67 measurement ......:D and use a drill one step larger than your pin ,if your pin is 1/8, drill the holes with a #30 drill bit...confused me for moment .
3mm is 3mm and next one is 4mm in my world ...................:) All between is special one . ......like 3.1mm , 3.2mm etc. :)

This numbered drill bit system is weird. Why are there only three steps between 3/64 and 1/16, or 1/8 and 9/64, but six steps between 5/64 and 3/32?

Hah ... you are looking for logic and rationality in the non metric system? The full stops (1/8, 3/16, etc) only exist because they can be defined as the ratio of two integers - not because there is something existentially good about those particular diameters - there is no other rationality behind it (in the metric system, everything is defined by rational internal relationships - even down to defining the dimensions of sheets of paper)..

Seriously though, one of the experienced machinists out there (Busto?) might have a reason for the multiple special steps...)
 
C Cushing H. When you drill wood, the fibers compress, then after you finish drilling they expand. Coming back hours/days later the hole will often be smaller than it was originally.

Try drilling them again and immediately try your pins.

I see this immediately after drilling also. I also see it with holes drilled in steel.

Sounds like maybe the point is not getting through: neither drill bits nor brass pins are exact in their stated diameter ... they each vary + / - to some extent (this is expected and observed ... I have measured both and see that variation). All it takes is the bit being a little small, and the pin being a little too large, for the interference between the hole and the pin to be too large
 
Getting closer to bevel time. I'm going to try and see what wood scraps I got, may build my jig 2nite if i can get some time.
There are some file Mark's i still need to work ou . It may do more of that after i work on the bevels.. just so I'm not cleaning up Mark's that are gonna grind away anyways.

Have about 4 2x6s around 3 ft long those should work! Its pouring now so building may have to hold off til tomorrow. Dont feel like sweeping the saw dust out of my garage lol
 
Welllll, not close to perfect lol, got some sanding to do, should I work on the tip and base a little more?

Also gotta try and fix my plunges if I can
