Here is a simple mod for Power Custom Series 2 fixture to enable it for sear work - i.e. to function as Series 1.
This saved me shelling another $200 for something that can be accomplished relatively easily if you have access to a milling machine or you are good with a hand file.
Here is the starting point - a stock Series 2. The mod will re-purpose the components shown below.
Here is the modded fixture
Tighten the set screw to keep the sear block in position
Here is the sear adapter (I used a piece of scrap aluminum to make this one for kel-tec sub 2k sear)
Then drilled and tapped a hole for the adapter screw
Here is the adapter mounted
When the sear is installed into the adapter, it is clamped in place with the clamping knob / block
I made a stone holder (from a 1/2 aluminum square) which enables me to use thin 1/2" stones manufactured by a US company - Boride. They sell high quality stones, but they will break unless put in the holder.
You can see from the picture that the holder is not flush with the sear surface. Depending on the angle this can be fixed either by lowering / lifting the elevator or by tilting the sear block and re-tightening the set screw. I chose to tilt the adapter a little bit and then use the elevator to fine-tune and arrive at the factory "zero". I will leave the actual trigger job for another post, though.
Here is another view, with adapter tilted and re-tightened. Assuming we have arrived at zero, we can use the elevator for all fine adjustments towards positive or negative engagement.
This pic shows the fixture prior to the bluing of the new components (this also shows the stone holder in action)
