I agree. I was rushing things. I had placed the order for the "roll pin pusher" tool I mention in my reply to you, but it won't arrive (now) until Thrs. I have replacement pins on order, and as long as I'm careful, I can pull the errant pin out wtihout any damage to the lower or the trigger guard. But I will wait for the proper tools. Unfortunately, the wrench you provided in your videos was like $69.00 on Amazon. Couldn't afford it. The roll pin pusher is only $39.00. Anyway, lesson learned. I'll try it again once the tool arrives. |
Actually I have only used vise grips. Squeeze, unlock, turn tighter and squeeze again. I wrap blue tape around the jaws and use needle nose players to hold the roll pin in alignment. Then a short squeeze to get it started. You also have a roll pin in the upper for the forward assist. Squeeze there as well.

I punch my pins in with no problems but, squeezing them is a lot safer (and probably easier with the right tools).

My first few builds I would sandwich the stripped upper between a couple of wood blocks and torque the barrel nuts down. Then on one I was tightening and trying to get the tube aligned when I hear a “tink” I cracked the lower part of the upper at the thin spot where the ejector port is. Was probably just unsupported by just a bit and the whole stripped upper is scrap. $90 mistake at the time. I still have it to remind myself to go slow and not do any unnecessary banging or pressure if not needed. |
Yep, mistakes can be pricey but, we learn from mistakes. (Ours or others). I use a block designed to hold the upper with and insert to prevent it from collapsing in the vice. It still has some play that I don’t care for so, I just take my time with the barrel nut alignment (aiming for the lowest torque possible). When inserting the trigger guard pin I put the guard in place to prevent flex on the ears as well as support the lower ear on a block (when later down). Then, lightly tap in the pin till it’s flush. Patience is key.

You got me motivated, I just ordered 2 'naked' lowers yesterday. http://www.cotep.org/forum/images/icons/icon14.gif

Me or C aleb? :D Anyway, I have a 2nd lower as well. But I will wait for after the election to build that one out. As long as Pres. Trump is re-elected, I can wait a little while, and recover other of my inventory (shotties, my P226, etc., my Shield), and maybe look at a P365 as well. If Biden is elected, I'll have to scramble for the parts for that lower immediately, especially since I doubt I'll get my hands on any other replacement items... :mad: Still waiting on some spare parts that were delayed 1 day until tomorrow. Then I can resume the build. |
