Getting ready to finish up these two 'artillery' barrel conversions.
First will be the Lahti. Still needs a feed ramp, extractor notch, and accelerator cut. And dust cover installed.
(34) Cutting feed ramp with barrel installed. Need to match the partial ramp angle in the barrel extension.
(35) Barrel removed; milling extractor notch. Doing it a bit differently than usual.
(36) Milling accelerator notch. I did two long Lahti barrels some 25+ years ago; can't recall how I did it.
(37) Dust cover installed between barrel & extension, barrel torqued into extension for final time. Tools in pic are -
-- Barrel vise
-- Barrel reinforcing rod
-- Receiver [barrel extension] wrench
-- Receiver reinforcing block
-- Spirit levels
-- Wrenches/sockets
The refinished barrels/receivers are on the way back and pics will follow...In the meantime...
When my Lahti M-40 bolt was disassembled for refinishing it was found that the firing pin spring [14] was broken into two pieces.
It still functioned (I shot it dozens of times) but it is still something that I think should be removed & examined.
The firing pin and spring are both held in place by a pin [13] which needs to be driven out to clean & inspect the firing pin/spring.
Pic attached.
