Hi all. I've tried extensive internet searches, YouTube videos, searching here, taking my TX apart more times than I care to, even emailed Motorhead a couple of times (very appreciative of his responses), but I've reached the point of reaching out for some help.
Some back story.....I purchased my TX in "FAC" in .22, 2017, shot it for a while, decided to ship it off for tuning to try to get it down as close to 12ft/lbs as possible and try to improve its' overall shot cycle, trigger, etc. It's been running very well over the past few years except for the occasional times the safety won't engage and of course tightening stock screws before shooting. It has the ARH improved cocking shoe and ARH stainless steel fore stock mount piece.
About two weeks ago, was taking some target shots and all was good until I cocked it and it made a strange sound and I thought it may be ready for a relube. Kept shooting a couple of times, then the safety would't engage/set no matter what I did, then it got to where it wouldn't cock. I will say that I am not a gunsmith nor do I pretend to be one, but I'm fairly mechanically inclined (when I want to be). So began my intense research into this problem and making sure I was well acquainted with the disassembly before I took a tool to my beloved TX.
The aftermarket spring guide had broken and sent some plastic/delrin into the works. Spring looked good as did the smaller top hat.
I cleaned out the compression tube, piston, and trigger block. The nut on the compression tube looked tight as ever. The piston rod looks good as it sits flush in the middle of the piston seal top.
I decided to reinstall the original spring, spring guide, and top hat. After applying the moly I put it all together.
After a few tries it still refused to cock. So, I take it apart, but befire I do I watch "Shootingatdawn" on YouTube and his excellent video of the CD trigger disassembly. I did the same, but before I messed with it I manually cocked it and a couple of delrin shards fell out. I then took apart, cleaned well, relubed, made sure everything moved freely and cocked, and put it back together. I did not adjust the first or second stages of the trigger.
Put it all back together and wouldn't you know it? It wouldn't cock. Took the trigger assembly back out. Made sure every thing moved freely.

This website helped quite a bit. Seemed the middle sear was "grinding" on the bottom sear. So I mollied the poopake out of the bottom sear. I apologize, but I don't have a pointer, but above the trigger blade you can see the trigger pull weight spring below the bottom sear, which I back out a quarter turn, but have since turned back to its original place.
It seemed to help as I could now manually engage the middle sear by pressing on the top sear. I thought this should be the ticket. Reassembled, confidently went out side, grabbed the cocking handle with gusto, and was quickly disappointed. Didn't cock. So, back to disassembly and reassembly. I've tried using the original top hat, original top hat with spacer, no top hat, tuned delrin top hat, etc. Made sure the original spring guide and washer are properly installed, screws were properly installed, everything was properly lubed, nothing binding, etc.
I'm unsure of what else to do. Originally, I thought I could just reinstall the original stuff and all would be well. Now I'm thinking maybe some violence took place in the trigger assembly those 2 weeks ago and I'm S.O.L.
TIA
ps, when saying it won't cock I mean it will not engage the sear or more accurately the sears in the trigger assembly
