Wanted to get a new post up for a week or two now. The usual stuff keeps getting in the way--the yard, the house, the job. Finding the time and finding the enthusiasm after work can at times be daunting.
I've shot these pics at least 3X over the last five days and the light has never been right. Everything kept getting washed out. OK, enough about me.
What was the comment on the Pyramyd Air blog the other day? "Life is not a pony farm."
Since I've come clean about not doing much to blog about, I did make some recent minor updates to the TF79.
I was on that trigger kick a few weeks ago, didn't mention it at the time, but the TF79 was also modified. Didn't think this would get any screen time, so no before pics. The rifle had that funky pivoting blade that was supposed to simulate a two-stage trigger. It worked about as well as you'd imagine from that description. Cut it off, added a stem and made the aluminum blade shown here.
It adjusts on the rod for height and angle.
Look, I was going for low hanging fruit--and I'm an admitted sucker for target rifle accessories--so I made a quick set of adjustable weights to fit the Anschutz pattern accessory rail. Didn't you ever look through the Anschutz target rifle accessories and want to try every single one of them--but couldn't afford them? Maybe one will turn me into a stellar shot.
Just a piece of 8mm rod for the shaft and a bit of milling for the attachment block. My Aeron target pistols also have adjustable weight(s) so I made all these weights interchangeable.
In a stupid move, I made this attaching block from 304 stainless steel. Forgot just what a pain it is to machine. It work hardens as you drill or mill it. Carbide tooling is the fastest sanest way to go. Next time, I'll just order a piece of 303 stainless or some 12L14 and save my patience.
Note to self: Purge the scrap bin of any and all 304 stainless.

Is 316 Stainless just as bad/worse/ not as bad to machine as 304?
-Yogi
Unfortunately, 316 is just as bad. The challenge is that many stainless steels like 304 and 316 work harden as you machine them. Just drilling a hole can seem difficult to impossible sometimes. The drill bit heats up and gets weaker/duller as the stainless likewise heats up and only gets harder. Carbide tooling is a great solution if you have big enough (rigid!) machines. Likewise, flood coolant is also useful. Both of these are typically lacking for home machinists. Sharp tooling, slowing down RPMs and feeding a bit harder is usually helpful.
