Day 6 - Sunday 25th, March
With the barrel and barrel bushings arrived some more work could be done :) The 25mm HSS drill bit had also arrived so the heatsheild could be worked on.
Here's the barrel shoved in to stage up what it'd be like, a Desert Eagle and a cuppa give you an idea of scale :P
These are the bushings we're going to use for the barrel:
Working on the Heatshield: First we drilled some pilot holes....which weren't big enough so we drilled them out to 13mm then used the 25mm. It took a very long time to drill through the metal as the pillar drill needed to be set to slow.
We'd been spraying it with oil in case you're wondering
All the 13mm pilot holes drilled out:
After a few hours of drilling and tinkering with the pillar drill the last hole is drilled out:
While MadDog was drilling the Heatshield out I worked on the piston mount. Welding it onto the lower body - bit of an horrid weld but really needed to make sure it'd stand up to the punishment (Arc welding is hard to get neat and I'm a n00b at it anyway :P)
That's fresh from the welder - that's why it looks wet ;)
The heatsheild all drilled out:
Needs some touch up but we'll do that tomorrow :)
