That worked surprisingly well for surprisingly long, but the edges eventually came loose and, after far too long, I deployed the Tiny Sandblaster™:
Kenmore 158 – matte cover plate – feet
The mottled matte effect isn’t quite what I expected, but it’s better-looking in person and we deemed it Good Enough™ for the purpose.
You saw the foot on the left in the previous effort:
Kenmore 158 – matte cover plate – feet – detail
The rounded plate directly under the needle sits far enough back to not reflect any of the LEDs toward her normal operating position, so we decided it didn’t need sandblasting.
American Standard Ceramic Faucet Valve Cores – old vs new
I think the sliding fit between the two ceramic blocks laps itself into a more perfect joint, to the extent it’s wrung together and can’t be moved. Even after filtering, our town-supplied water apperently has enough micro-fine grit for the purpose.
Shooting the modified copper elbow with gloss black atop gray primer definitely improved its disposition:
Floor Lamp – painted elbow – installed
I’d have been more inclined to apply several light coats if the wind weren’t blowing up a storm. As it was, I shot enough black to cover the not-quite-dry primer (“top coat at any time”) and called it a day.
The scuffed tubes aren’t quite that ugly in person, but they have suffered some abuse along the way. Seen from a normal working distance, however, it’s all good:
Floor Lamp – finished
The lamp isn’t quite as tippy as I feared, so I’ll try it without the broken truck spring counterweight until something untoward happens.
Mary’s long-suffering garden rake pulled apart while we were flattening a section of what will become something like a lawn next to the garden:
Garden rake – shank and ferrule
For whatever reason, there’s no cross bolt holding the shank into the ferrule, like there should be on any tool subject to pulling force.
After marking the wide spot on the shank, a couple of good shots with a two pound hammer flattened the ferrule around it well enough to start a hole with a 3/16 step drill:
Garden rake – cross drilling
Go through the far side with a 13/16 inch drill for a generous 5 mm fit, drop a bolt into the hole while it can’t get away, tighten the nyloc nut, and it’s all good:
Garden rake – cross bolt
In fact, it’s better than it ever was, because now the shank can’t pull out until the ferrule falls off the handle. Which could happen, but I’m not averse to another bolt.
Admittedly, it’s not a stainless steel socket head cap screw, because that’d just about double the value of the rake. The handle is in such bad shape that the bolt will probably outlast the wood …
Done!
Update: The consensus says I totally missed the Ritual Invocation of the Epoxy, so:
After trimming off all the extraneous bits, the larger half of the connector (male pins) fits through the tubing and the smaller half (female sockets) barely fits through the bottom bushings.
It turns out half-inch copper pipe fittings (ID = 15.9 mm) almost exactly fit the tubing (OD = 15.7 mm):
Floor Lamp – copper 45° elbow
A quick test showed the 45° (actually, it’s 135°, but we’re deep into plumbing nomenclature) positioned the lamp head too high and with too much reach:
Floor Lamp – gooseneck exercise
So shorten the tube attached to the head and deburr the cut:
Floor Lamp – tube deburring
The 45° fitting is too high and a 90° fitting is obviously too low, so cut a 20° slice out of a 90° fitting:
Floor Lamp – copper 90° elbow – 20° cutout
Cut a snippet of brass tubing to fit, bash to fit, file to hide, buff everything to a high shine, silver-solder it in place, and buff everything again:
Floor Lamp – copper 90° elbow – 20° fill strip
The 5/8 inch aluminum rods serve to stiffen the fitting, smooth out the torch heating, and generally keep things under control.
Wrap the obligatory Kapton tape around the butt ends of the tubes to fill the fitting’s oversize hole, put everything together, and it’s just about perfect:
Floor Lamp – copper 70° elbow – installed
I immobilized the fitting with black Gorilla tape, but it really needs something a bit more permanent. One of these days, maybe, a pair of setscrews will happen.
The additional reach required a little more counterweight on the far side for security, so I added the broken stub of a truck leaf spring. It should be secured firmly to the base plate, but no tool I own can put a dent in those three pounds of spring steel. Maybe it’ll merit a fancy enclosure wrapped around the base?
Grab the buckle in the Sherline vise, center on the post hole, and drill a #38 = 2.58 mm hole:
Reversible Belt Buckle – cross drilling
Tap it M3×0.5, clean out the hole, tap the post + spring back in place, dab threadlocker on the shortest M3 setscrew from the assortment, snug down on the post, and reinstall the belt:
Reversible Belt Buckle – M3 setscrew installed
Looks like it grew there, doesn’t it?
Now, as my buddy dBm will remind me, the real problem is too much weight in the saddle, but this fix should move the symptoms elsewhere …
The pivot on the Fiskars Small Detail Scissors (the name is larger than the hardware!) in the bathroom gradually worked loose to the point where I hauled it to the Basement Shop and whacked the rivet with a concave punch:
Fiskars Small Detail Scissors – pivot restaking
Setting the rim of the rivet down a smidge tightened the joint wonderfully well and two oil dots smoothed the action.
I grew up using these concave punches (I have several sizes) to set finish(ing) nails, but apparently real nail punches have a nubbin in the middle to engage the little recess in the nail head which used to be common, back when finish nails arrived well-finished from the factory.
They’re not roll pin punches, either, because those have a different nubbin to support the inside of the pin.
