Whats up everyone! New to the forum, and new to knife making. I am currently on my journey with my first knife. Shop is still being finished up, but I am in the process of ordering tools and materials. One of many issues that I am having the most trouble finding an answer to is in regards to the stop pin. My design has an external stop pin that will be pressed into the blade. I am using CPM-3V steel at .190 thick. My stop pin is .1873 diameter made out of Hardened 440C.
The question I have is how much smaller should I ream the hole for a good press fit?
I understand there are many variables in this question that will affect the outcome. Runout of my setup, post HT changes, etc..
I am really looking for a good starting point. I am sure I will still have to undergo some trial and error, just want to minimize it. You can always remove more metal, can't put it back.
Reamer options I have are:
.1862 (.0011 undersize)
.1866 (.0007 undersize)
.1870 (.0003 undersize)
Which drill size should I use? #14, #15, 4.5mm, #16, #17? I understand that drill hole size can impact final reamed hole size.
Lastly, any use of some type of loctite or epoxy to ensure it stays put?
Thanks in advance!!! Looking forward to learning from everyone!!
