teven,
The tried the end grain plugs once, hickory, but my taper ream just shredded the grain rather then cutting it. The ream was mostly new but not the best quality, smooth on one side and three cutting edges on the other. Perhaps a spiral cut ream would perform better? The hickory I used is, well it’s hickory and hard as a baseball bat or hammer handle.
I’ve taken to just case hardening then bore with thin CA, letting it cure for 24 hours and then reaming again.
I’ve also been doing the same with my wooden pegs only two or three layers scraping after each application.
With care I’ve been able to make the bore and pins exact enough to be interchangeable. I start by making my pins 1/4” on the small end and all other dimensions fallow.
Looking forward to the rest of your build.

In the plug inserts- I think it’s not about hardness of the surfaces the pegs engage, but evenness of grain. We’re trying to get the peg shaft to ride against one direction of grain orientation by making the plug with end grain.
The wood only needs to be of similar hardness to the peg. I’ve found Maple and Teak to be very good. And I currently use a Japanese hardwood the name of which I can’t remember now, but it’s a lot like teak but not oily.
Reamers are weird, they cannot be sharpened by mortals with clunky home shops. Maybe a machinist could sharpen one. You store your reamer wrapped in paper to keep it from touching other tools. It may be chattering because the hickory is too hard. You did use end grain right? I’d switch to maple or something similar if I were you.
And be careful what you lie about. If you lie your nose will grow and you’ll be a wooden man. If you continue to lie your wife may kick you in the balls. That’s going to hurt, and it will send you to the hickory dickory doc.
