hey there,
I took a few pics of what I tried to do quickly tonight to finish the day as it is the smallest detail possible on that run I think, but I just couldn't supply something that wasn't completely accurate, so I had to do it!
the slot in the screw at the bottom of the clippard assembly, as visible on that ref:
I searched hard on my free time to find a job lot of clippard parts for the cheapest possible price for you guys, especially for the non US people on that run that would have more trouble sourcing them. I managed to find a nice lot of 11 of the MPA-3 tubes and it came with a lot of the small L fittings that go under it on the ZF-1, but they didn't come with the special screw to attach them.
the story goes on when I tried to source the special type of small 10-32 bolt for a reasonable price and ended up finding a nice lot in France. after 3 weeks, the screws were never sent and the seller was never responding to my enquiries. I ended up filling an ebay claim and the guy finally showed up and said, "oh yeah, sorry, I wasn't there, here is you money back, I'm closing my ebay account anyways". ok... this is just one of several orders that I never received for that project, crazy times!
so, I sourced some new ones from Germany and they finally showed up this week. Obviously, they didn't have the slot in the head so I had to find a way to do it. that is what I did tonight.
Sorry, as always, I talk a lot, but I wanted to find a good deal on those parts and supply the kits as drop in screen-accurate replacement, but those parts were a lot more trouble than anticipated, that will all be counted on my "free time" for you guys, but just wanted to let everyone know how it actually went ;-)
SO, I decided to give a try to the slots with... the slitting saw, logical you say.
so here we go!
worked beautifuly:
the thing is, this is A2 stainless steel, and it only worked beautifuly for 8 screws, after that, the blade starting hissing like crazy and here is the result, RIP blade:
the "angles" you see are not supposed to be here, the end of the teeth is normaly 90° on the full thickness... oh well! I'll do the last 3 with a guitar nut slot file I think

luckily I have a second blade, because that's the blade I need to slot all the rocket tubes!
cheers guys
