so waht ya doin today?

FB, this is no ordinary 4th-order BP box, it's a fixed version of the Decware Deathbox design which is extremely tight and full-sounding without being ridiculously punchy at high volume like sealed boxes can be. Putting a 4th-order inside a vehicle also cures a lot of the weird loading problems that speakers can have when firing openly into a vehicle cabin. A single 10 in one of these boxes being fed about 100 watts at comfortable listening volume will blow away a pair of 12s in sealed boxes being fed 250 watts each, and the original Deathbox can be tuned to optimize the T/S parameters of the subwoofer being used and the cabin gain characteristics of the vehicle it's put in. The trick is to get the Deathbox situated in just the right place, tuned, and time-aligned with the mains so there's seamless connection between bass and sub-bass. I did that with an actual Deathbox and copied the chamber dimensions for my console, but made a fixed baffle and slightly altered the form to fit the space since the DB is too wide to fit comfortably between the seats. Right now, with just the front mains and sub going, the sound stage feels and sounds like a 30x40' room when it's only 4.5x5x9.5'.

Having lost most of my hearing above 4000 hz to repeated childhood ear infections, 1500 hours PIC behind or
in front of Lycomings and Continentals, and probably a couple million rounds of shooting, albeit the flying and
shooting with the best hearing protection I could find at the time --- has certain advantages in selection of
audio equipment.
It mostly pretty much all sounds the same. A real money and time saver.

I know what you are talking about, Ian, but it is mostly acoustic wave theory to me.

Ian's text was way over my head, and engineering on that level would be wasted on my jacked-up hearing anyway. I have already elaborated on the luxuries that hearing loss can provide, so no need to re-visit that subject.

 

[Winelover]

I have a 1/2 deep well socket that fits the lugs, a 1/2 breaker wrench and a piece of cheater pipe that fits over the breakover bar in each kit. Wimpy little wrenches that come with the cars and even trucks, are useless.

That's what I use and what I bent...............

 

[Winelover]

Repaired and maintained air tools at GM for over ten years, sans hearing protection. Not hearing friendly.

Hmmmmm, after reading Ians post all I can say is I've almost figured out how to set the clock in the radio in my truck...almost. Used to write tickets to the kiddies that would have their portable concert systems blasting away. Got a standing ovation from what were apparently the kids neighbors one afternoon. To each their own I guess!

Got a crap load of stuff done yesterday, a lot of it involved actual crap/feces/manure/animal waste/whatever you prefer to call it. Got a winters worth of trash picked up out of an area that seems to collect wind blown stuff every winter. Gord picked up all the sticks from the brush he insisted on feeding the goats last fall and then left in the paddock for me to trip over. Got SWMBO rabbit/unspayed cat house cleaned out, relocated some rabbits and spent a bit of time cleaning Angora rabbit hair out of the buildings fans. Pretty sure I could have knitted a sweated from the hair I cleaned out, if I could spin and knit that is! This building was an Amish neighbors wood shop before we traded a heifer for it. Pretty decent building, about 16 x32 IIRC. Had a heck of time getting it out to the road but once I got it off the sod and rock we skidded it down the road/shoulder the mile home nicely. Even thought to get permission from the Highway Super, which is more than some folks do. This never would ahve flown on a state or county road where running steel plows over it from mid October to early May is fine but pine 2x12's might "damage" the road. Got me, I don't get it. Definitely need to add some support under the building, it sits on stone piers. I think 3 (one under each floor beam) would do it, but I'll aim for 6 spread out equidistant, have to see how the time factor works.

Moved a chicken house and found rats. Gord got the Rat/JackRussell Terrier on them but his attention was on the chickens running around. some training in order there if I was serious about it. The German Shorthair/Pit mix did better and got a couple. I could have done better with my 22/45 Ruger. I did get 2 with a manure fork. Crappy way to die, pun intended. Got a mess of other stuff done to, mostly housekeeping type barnyard projects. Too wet to spread manure, so the stack is growing. Thought I was going to get the lawn mowed, not that it is really dry enough AND get going on the big fencing project, but that didn't happen. Did discover my higher end fence controller is not working. At least this one is fixable.

Rained again some more. I'm tired of rain.

Brett what kind of sheep dogs do you have to help you with the flock. I had like a fifth cousin who raised sheep and trained champion sheep dogs. If you wanted to get his eyes lit up just ask about one of the dogs he had pictured on his walls. He'd talk for an hour.

 

[freebullet]

I ain't putting nothing in my vehicles called a deathbox. Lol, I'm sure you'll get it sounding how you like.

Sealed enclosures can be manipulated similar to effect desired output. Have a couple tang band drivers I'm making mini sealed boxes for, to take up wasted space in the work van. They will be ran from a bridge-able head unit. Good enough for a work truck I guess.

 

[JWFilips]

I think I like your wife's attitude JW.

She is a tough cookie! After 42 Years of marriage I can tell you one thing for certain....I would be nowhere without her! She is my life!
My childhood sweetheart, my rock, my financial advisor...et al! She is the only reason I get to do the things I love to do!
Fix her brakes ..well sure...no matter how much I hurt this morning! I got to shoot from 7 am until 9 am & wash and pick thru 97 pounds of range picked bullets ( which she helped me with) Don't think I can ask for more!
Jim

 

[fiver]

mine will help pick them up at the range, after that I'm on my own.

mucked around between rain drops for a bit then come in and watched the Indy 500 qualifying.
got a couple of fake tube Jigs tied in black and silver, which I think will turn out to work well where I bass fish.
I also tied up a skirt on a spin jig which is something new I want to give a try some time this year.

 

[Brad]

Mine helps with collection of range scrap but after that all she does is complain about the 7 buckets in the garage.

 

[L Ross]

The shoot went splendidly, my friends had fun, the food was outrageous, whisky got drank, bull got shot, deals were made, wonderful time! I did end up getting a Model 25 Remington in 25-20. Cute little poacher's rifle.

 

[Pistolero]

Interesting rifle, I had to look that one up. Looks like a pump .22 RF at first glance....meaning
that in a handy, convenient way. Don't know much about the cartridge. What bullet weight
and velocity is the norm? Is that enough for deer? Seems like a small game gun, but not really
aware much about the cartridge so maybe not. Sleek and pretty.

Bill

 

[fiver]

small game is it's thing.
the case holds like 14-15grs of ball powder, not a load just a volume [aa-a1680 is a happy camper here] and throws a 60-85gr bullet along at about 15-1600 fps.
I use a 72gr plain base with AA-2230 under it at about 1450 fps or so in my little carbine.
shot everything from squirrels to turkeys with it.

 

[CZ93X62]

Oh, the 25/20 WCF. And you guys thought I waxed poetic about the 9.3 x 62 Mauser.....

I have two rifles at my house that house this little rat whacker--the older one (MUCH older) is a Marlin Model 27-S slide action rifle. It is the "the little rifle" ranch gun from my family's ranch holdings prior to the Great Depression. I do fire it a bit, and it has some utility as a varminter despite its vestigial open-irons sighting gear. It gets fed Lyman #257312 (89 grains in 92/6/2) with enough 2400 to prompt about 1400 FPS. These hit reasonably close to where the sights look. Its restoration is a work in progress that goes in fits and starts.

The other newer example is a Marlin Model 1894CL-series levergun from about 1988 or so. It now has a Lyman aperture sight installed, and had in the past worn a 4x Weaver to see what its loads could accomplish. Several months of that drag-sequence showed little gain over what I had been doing with the apertures since I bought the rifle 30+ years ago. Its best bullet is the jacketed Speer 75 grain flatpoint, but close behind are the Lymans #257312 and #257420. This rifle has had A LOT of shooting during its lifetime--it is well past the 3,000-round mark and still doing well. It has accounted for hundreds of varmints over the years.

It is among the better cast-bullet rat-strafers, though kind of in decline. I think Kimber put out a few bolters in 25/20 WCF in their early years. A lot of the late-series Marlin 1894CLs are "chambered long"--the shoulders blow forward visibly upon firing. If you set the sizing die to not move the shoulder back, case life can be good--if you screw the die down to meet the shell holder, cases last 2-3 firings before head separations onset--and case trimming every reloading cycle.

 

[Brad]

A lever action 25-20 is on my “must find” list.

 

[RBHarter]

I got out to really shoot some today . I shot some work ups I loaded about 18 months ago . 6.8 SPC NOE 279-124 FP over H4198 , FC brass , CCI #41 in an ARP 20" rifle gassed H-bar barreled BlackThorne Products kit on an Anderson MXR lower . 1-10 5R , .271×.277 my notes say . I size the .2795 as cast through a .280 sizer to lock the .277 copper Hornady check , I get just a scuff on the base band . Home lube of paraffin , Vaseline , and STP . Alloy is 75/24.5/.5 WW-1/20-copper water cooled to 18 BHN . This alloy is quite malleable on impact like air cooled WW . It's very capable of 2400 fps as well .

First thing off I've never been to this range . It seems to have a permanent 3-5 mph straight down the range . I've shot worse ranges . It's situated facing north down range and enclosed by 40'+ pines and it's on USFS land .
It's fitted with 5 concrete benches with swinging fixed hight seats for righties and lefties . They are a little rough but they've been there 20+ years so overall not bad . We had it to ourselves so that was cool . My bag worked out all but perfect .

Next up after shot #2 the scope , a 4th hand Burris TV duplex was blurred ....... It would appear the objective lens has moved and/or something has slipped inside . It was on a Savage 308 bought for my daughter in 2000 so I don't feel real bad about it giving up . So I did what anybody would do and took it off to use the flip up irons ....... Yeah . About that I guess matched pairs are probably a good thing these aren't and they don't get along real well . The elevation is all up front and it's all the way down rail mounted on the free float forend ....... Good times , it still hits 9" low at 25 yd .

The workups were not awe inspiring but 4 steps of 3 each of 20.8 , 21.0 , 21.2 , 21.4 , and 21.6gr each showed a steady closing of groups with zero climb or or crab . So I still have to load it a bit hotter . I will also have to get a replacement scope on the beast fortunately I have a couple of them without a place . I have a nice Weaver K4 fine wire El Paso . The duplex made me lazy but this guy should shoot flat enough to 200 it won't matter much .

Ms picked bullets , got enough to fill a half liter bottle .

We don't have herding dogs, we have guard dogs. The herding breeds, the Border Collies, Australian Shepherds, etc, are the nifty, smart ones everyone loves to watch. Watching a Pyrenees means staying up at night listening to him bark and bark and bark and occasionally turn into a white lion charging across a pasture to tear into the not too bright coyote that thought he could sneak in a grab a meal. I can go on for hours about them, but it's mostly thanks to them for saving my bacon....well, lamb actually!

Mowed most of the lawn yesterday, worked with the new horses some and got a slight sunburn. Better than snow. Had quite a few thunderheads move through but they all seemed to act up south of us. We can sort of see 15-25 miles as far as cloud cover goes and it was hitting hard down on Ft Drum I'd say. Got to be on the road quite a bit today.
