Day two.
Finished file dressing the frame.
Lapped the slide and frame.
Got the take down lever working great.
Filed the barrel feed ramp and the insert block, but most of the material I took off the barrel feed ramp. I dressed the insert block area well though.
Fitted the trigger and trigger bar. The only issue I have is at full rewards pull the trigger sticks in that position. I will explore the trigger heel / insert block to see if there is a binding point as per JOE-BOY or perhaps the trigger bar is encountering friction with the frame somewhere at the very last part of the pull.
Fitted the de-cocking lever. Still have to remove a bit on material either from the de-cocking bushing or inside the frame for the de-cocking bushing to lay flat.
I fitted the mag release and pins. That worked well. At first I didn't realize that the far side of the mag release is a slide in plate that locks it there. It works well once you realize that there is a dove-tail capture for the plate.
Tapped the grip screws to the Dlask 3mm x .05mm pitch. I dremmeled the round pads (just the part that need removing) so the Dlask grips would sit flush. Sig grips fit the pads correctly but the screw holes are mis-aligned. I don't have Sig grips but this information comes from JOE-BOY.
It should be noted that the pre-existing holes are slightly too small according to spec. for tapping. I drilled them to 2mm before tapping to 3mm x .05 mm pitch and this worked very well.
I got into the two dreaded areas at the end of my work today. The plastic trigger stop block and spring and the trigger bar! I filed the sides carefully of the plastic trigger stop, so it wasn't tight to the fit, but the 2mm plastic stop block pin, when installed, doesn't allow the trigger and trigger pin to be inserted. The plastic block has the correct radius for the trigger but it pushes the trigger too far forward for the trigger pin line up. I tried to dremmel away some of the plastic in the radius area, but that didn't work so well. I ended up bending the hammer stop block spring and generally made a mess of it on the inside. I do however, have a cosmetically good plastic trigger stop block from the outside, but is is minus the spring. However it IS in one piece.
I think it will be okay however. The sear,safety, sear tension spring, and ejecition piece seems rather daunting. I have started to fit the various pieces and did some dressing on the trigger bar and the sear seating on the trigger as per Joe-Boy showing us the radius to reduce material to allow the sear to grab more. I did some filing of the trigger bar for DA action as per the other link that discusses this build as well. I can see the is going to be pretty niggly to get it just right. My prelim test look like DA will work out. The trigger bar just releases the DA slot on the trigger at a position not quite to the point that the sear would engage.
HERE is a PROBLEM I haven't figured out yet. I have a problem of the trigger bar not coming quite far enough forward to push the safety far enough to disengage the seer. Perhaps more tweaking is going to help.
And here is a problem I need help on.
My slide and barrel will not slide past the normal position. It is not the feed ramp hitting the insert block. The take down lever is in the down position. It's as if the barrel will not disengage the block and the it seems like the barrel lug comes against the fitting block. I can't see exact;y what is happening. Damn old man eyes (well not that old) and is is very dark in there even with a flashlight. There is no movement of the barrel (seperating from the block) but the guide rod will stick out about 1 cm when a push the slide back as far as it will go. This is not very far - perhaps 1 cm past it's normal slide forward position.. It the appears to stop hard as if metal is hitting metal. And I don't know where but I think? It may be the barrel lug hitting and the insert block cross piece?. It should be mentioned that this happens no matter what state of assembly the pistol is at. It happens with the bare minimum of: Slide release/ spring, insert block, take down lever (in the down position), It also happens with the pistol almost entirely assembled. It does not happen when the barrel is NOT installed. I'm hoping it something easy that I am unawre of. But will have to investigate further.
Day three tomorrow!
