A pleasant summer day (metal content)
Back in town, daughter Karen and I went to the range today. She's
visiting from NYC for a few days, staying with her brother here in town. His house is way bigger than ours. She didn't care much for the rifle (.22-250) but she does enjoy shooting handguns. So it was mostly just a fun gunsmoke outing on a lovely summer day, a fine outing indeed. She did enjoy the exploding water bottle show, everyone does. She shot one so she could say she did. Sniper Karen, one shot one bottle. Hey, I once saw two guys with a rather expensive rifle with some very nice optics fire more than 12 rounds at a water-filled plastic bottle at 100 yards without ever hitting it. I shot the other two so she could see them explode thru the spotting scope. She broke out laughing both times. We used the 100 -yd general-purpose range because there was a match in progress on the benchrest range. That suited us because we could shoot at water bottles on the GP range and also shoot handguns by simply walking downrange closer to the target and berm. The 100-yd GP range does have a couple of sheltered benches for benchrest riflery. The other GP ranges have nothing but berms. After we were done we mosied down to the BR range to see what was going on. It was a 100-yd match with light and heavy varmint classes. Tomorrow they'll shoot at 200 yd. I asked one guy what sort of groups they see in these matches. He said anywhere from high 1's to low 4's, which means group sizes of from 0.1" to 0.4" max center-to-center distance between bullet holes in a group. I didn't see any of their rifles because they were packing up by then, but I'll bet they're not shooting off-the-shelf rifles. They'd all be custom-built for at least a coupla grand and most of that again for the optics. I smiled, said my best rifle shoots in the 3's on a good day. He looked at me like I was a turd in the punchbowl. Earlier I'd asked another guy if I could inspect a target frame he was using on an adjacent GP range since he was downrange putting up targets anyway. He said sure, so I looked it over. Easy welding project. I said it was neat, was going on my ta-do list for winter. He said heck, there's a bunch of them in the IDPA corral. (ed note: International Defensive Pistol Association) I said the guy who heads IDPA at the club doesn't want to let anyone have the combo to the corral who isn't active in IDPA competition. He said yeah, that's right. He then went on to say that IDPA is nothing like target shooting, requires far superior skills. Being a mere vet, I wasn't sure whether to salute, genuflect or curtsey so I merely thanked him for the look at the frame. Easy peasy welding project, but I can complicate it by improving the design for better portability. My target frame stakes work OK, but those GP ranges are almost like class V dirt road -- clay, gravel and sand -- so pounding stakes does work but not well. Both of these competitors reminded me why I dislike competitive events and tournaments. They seem to draw or inspire competitive assholes. I don't need that crap. I'm sure most are not like that, but it only takes one to tilt me toward skipping being exposed and irritated. I readily acknowledge that I have a very low tolerance threshold for such things. I kinda miss the range at Cambridge for its simplicity and the friendliness of the folks I met there. But I don't miss the drive, nor the haphazard scheduling with no communications. Driving for an hour and then being unable to shoot does not make my day. That happened twice at Cambridge. After shooting, we came home and eventually did an art project. Eventually because we arrived simultaneously with the London contingent so Karen got to say hi to Ann 'n Hassan and meet Bella. She and Bella (5) got on famously right away. Bella was a princess today because they'd been to the renaissance faire and Bella got a face paint job with lots of glitter (extra because the vendor noted her patience in line) and a princess dress. Oh my, she was something! Bella is having a swell time in America. On her list for this visit was a ride in PoppyDon's green boat. She got the ride last week, and she even got to drive the boat a little, going slowly. Not many kids in her class in London will have driven a Ranger bassboat. Thence to the shop. There's a form of Japanese art called tatebanko which involves making 3D dioramas with paper. Karen wanted to do a tatebanko but in sheet steel rather than paper. She brought this kit with her: http://www.architectgiftsplus.com/tapadikithom.html She cut out the various parts of the kit and then traced their outlines onto 24-gage steel with chalk. The steel was what was left from a water heater skin I salvaged years ago. Most of that metal got welded into various cars as rust repairs, but there was a little of it left. She then cut them out with the plasma cutter. She loves using that tool, and she's getting really good at it. It goes thru 24-gage steel like a red hot wire thru styrofoam. She could go as fast as she could follow the line, no problem. Her instincts were bingo. Plasma was definitely the way to do that. The "as cut" edges, cut freehand in steel with a needle-diameter jet of sun-hot 10,000 degree plasma, seem much more suitable for this art project than the cut edges scissors or sharp blade produce on paper. She then bent mounting tabs on the various pieces. We did that by clamping the workpieces between two pieces of heavier steel in a vise and then folding the tabs with a hammer. This jigging technique requires four hands to get things jigged up in the vise, but we had four hands so no problem. Then the trick is many light taps to persuade the metal rather than try to hurry it. She got pretty good at that after a couple of tries. No photos because the project isn't done. She'll bring the bits back home and paint or chemically color them one way or another and then find or make a box into which she'll install them with epoxy or silicone on the tabs. Then we'll explore some ideas for illumination. The idea of lightning came up, as in embedded white LED's being flashed by a little electronic gizmo some old fart might conjure up. Storm on Mt Fuji. We decided that use of butane or propane, while undoubtedly dramatic and capable of thunder as well as heat lightning, might not be a swell idea in a rented apartment in Brooklyn NY. |
