Catching Up.

Haven’t done anything terrifically exciting lately, but a few repairs and such have been done in the past couple of months.

The neighbor is building a new deck.IMG_3355
Unfortunately his palm sander died in the middle of sanding those cool tables…IMG_3356IMG_3357
I pulled out the old switch and found one in my junk box that was similar. Cut off the lever arm.IMG_3358
And trimmed the lug to fit.
Needed the hole embiggened to fit, but a bit of the case cracked. No problem though. Now it works fine and he’s been using it for a couple of months.IMG_3361
The old switch.IMG_3365
The contact was fouled…so it wouldn’t allow current to flow. So another tool saved from the landfill.


Some strain gages I got at a yard sale in a box of junk.

Back of a $3.00 shelf unit I bought at a yard sale in Philomath. ART!

Finally got Felice the log she’d been dreaming of.

Bought a USB MIDI keyboard at Goodwill but the USB wasn’t working but MIDI was.crack8crack7crack1crack0
Someone had whacked the USB port and cracked the board.
Scraped away solder mask.
And solder bridged. Probably should have added some epoxy to mend the crack but it should be fine.
And now it works.

The brackets for the neighbor’s greenhouse were bent when he took it apart for a move.
Some bending…IMG_3822

Joshua came over and soldered some fittings to beer kegs that are being repurposed for homebrewing.

Shiny bug in our neighborhood. Metallic borer.

Somebody dropped this LED lantern on the floor and the battery catch broke.IMG_3760IMG_3763IMG_3765IMG_3767IMG_3769IMG_3773
Another day, another fix.

Casiotone CT-370 Major Minor Key Repair

My Casiotone CT-370 had a problem with a loose power jack connection.IMG_3058IMG_3061
I desoldered the old one and soldered in a new one. It was pretty routine. This blog post isn’t about that.

Kitties! Again, not what this post is about.

I discovered that the F sharp (or is it G flat?) key has a problem. It’s loose and broken. Not really qualities I look for in a piano key. Or any key.

That foam is everywhere and is all nasty. But it’s a cheap keyboard and I’m not going to remove all the foam.
I found I had to pry this white strip away to remove the key, and the two white keys on either side needed to be removed as well.
Broken hinge end. I tried gluing it but it would immediately snap. It’s under a fair bit of force from the spring.
Just not enough meat to use adhesives.
Cleaned up.
Some suitable steel was cut.
Forming the channel with an arbor press, vise and a 1/4” square toolbit.
The channel.
Drilled a hole for the post.
The spring fits but I had to squeeze it slightly oval to get it to bottom out.
Some washers shim up the channel because of a step down after the post.
Two brass #2 screws fasten the channel to the key. I sawed a slot and widened it with files until it approximated the form of the broken bit. Some repairs are best done by eye.
That foam…nasty.
It fits! It came out surprisingly well for a speedy hack repair.
