Hose Fitting vs. Lawn Mower

This appeared while we uprooted a row of forsythia along the north border:

Although FOD has killed a good share of my lawn mowers and blades over the decades, this happened long before my administration and I can’t take credit for the precision targeting.

Round Soaker Hose Splint

One of two new round rubber soaker hoses arrived with a slight crimp, enough to suggest it would crumble at an inopportune moment. Rather than return the hose for something that’s not an obvious failure, I clamped the crimp:

Unlike the clamps for the punctured flat soaker hoses, this one doesn’t need to withstand much pressure and hold back a major leak, so I made the pieces a bit thicker and dispensed with the aluminum backing plates:

The solid model is basically the same as for the flat hoses, with a slightly oval cylinder replacing the three channels:

Garden Mole: End of Life

One of the moles aerating the ground around here ran out of steam beside the garden:

It has wonderfully soft velvety fur!

Flipping it over:

A closeup of its digging paws and gnawing teeth:

Those choppers seem overqualified for a diet of earthworms, but I suppose they know what they’re doing.

We left it in as-found condition, ready for recycling …

[Update: The consensus seems to be it’s a vole or shrew, not a mole. It’d be the biggest vole I’ve ever seen and “large shrew” seems oxymoronic, but the teeth are diagnostic. ]



Monthly Science: Vegetable Ice Crystals

Mary made a batch of veggies in tomato sauce and froze meal-size portions as winter treats. The moist air inside the containers froze into delicate ice blades on the zucchini slices:

The blade cross-sections might be oblong hexagons, but it’s hard to tell with crystals melting almost instantly after the lid comes off. Some of the smaller hair-like blades reminded me of tin whiskers.

Obfuscated Signage

Spotted in an arboretum:

Not for Public Admittence into the Area

How about good old “Keep Out”?

I’m not sure what the “do not touch” icon is supposed to mean, other than a lack of “no entry” icons.


Another Garden Hose Y Valve Autopsy

An outlet thread failed on yet another garden hose Y valve:

Out of an abundance of curiosity, I battered the remaining parts out of the carcass:

One of these days, we must buy an assortment of new fittings …

Step2 Garden Seat: Replacement Seat

A pair of Step2 rolling garden seats (they have a new version) served in Mary’s gardens long enough to give their seat panels precarious cracks:

The underside was giving way, too:

We agreed the new seat could be much simpler, although it must still hinge upward, so I conjured a pair of hinges from the vasty digital deep:

The woodpile disgorged a slab of 1/4 inch = 6 mm plywood (used in a defunct project) of just about the right size and we agreed a few holes wouldn’t be a problem for its projected ahem use case:

The screw holes on the hinge tops will let me run machine screws all the way through, should that be necessary. So far, a quartet of self-tapping sheet metal (!) screws are holding firm.

A closer look at the hinges in real life:

The solid model now caps the holes; I can drill them out should the need arise.

Three coats of white exterior paint make it blindingly bright in the sun, although we expect a week or two in the garden will knock the shine right off:

After the first coat, I conjured a drying rack from a bamboo skewer, a cardboard flap, and some hot-melt glue:

Three small scars on the seat bottom were deemed acceptable.

This original doodle gives the key dimensions, apart from the rounded rear edge required so the seat can pivot vertically upward:

The second seat looks just like this one, so life is good …
