Guest Submission: hardware conversions

One of my old friends and readers shot me a message a while back saying "I went to Bunnings (read: Home Depot, USAnians) and got a bunch of things to try out for the Apocalypse ..." and I thought it was high time that I gave them a bit of a write up. This is a decided departure from regular store-bought "tactical" gear, and look towards what "found items" might be converted into impromptu hand to hand weapons.

Such as this driveable post-socket spear which is lashed to a whittled post, and lashed on with leather strapping. With some rudimentary sharpening this makes a big two handed spear / axe / mace. These can be found holding up many street signs, fence posts and the like, and once pried from the ground make quite a formidable hand to hand weapon, or even giant ballista bolt head.

The second piece was a fence-post-topper, the kind of thing you see decorating fancy fences which my friend decided would make an excellent mace-head.

I've got to admit, whenever I pass a wrought iron fence, especially old, cracked or loose, I wonder how easy it would be to wrench a length free, and use as an ad-hoc melee weapon. This example is mounted to a long bolt, but could also be mounted directly to a post. I'm thinking the threading might lead to a weak point, especially under the heavy impacts a mace might expect, but hey, this is impromptu at its best. Use what you have, when you have nothing else, and Adapt, Improvise, Overcome. Thanks Karl!

Home front: vertical gardening

I have been wanting to make better use of the resources at my disposal for a while now, and grow more veggies at home. The problem being, we live in a very sandy location, and a lot of things that we like to eat just don't grow well. That or the possums, and snails, not to mention tiger slugs eat them before we get a crop out.


In order to avoid these pitfalls, and make better use of our bright sunshine, the water barrel I have out the back, and a lot of recyclable bottles I had had ready to go, I wanted to use the same kind of design as seen in a Kickstarter I backed in 2011 (but haven't yet seen) : Windowfarms.


The idea is pretty simple, plastic bottles, 1.25, 2 or 3L bottles, with the bottom cut off, have holes punched around the base, and then strung together in a stack.

Here is the top of my stack, and you can see the potting mix is already sporting some growth, sunflowers for Triceratops Girl.

I used just simple potting mix in my bottles, beccause it's what we had on hand from seedling planting to stock up the front veggie patches. I am hoping to keep building up our collection of these and get the most from the summer sun. I think a vermiculite substrate would be awesome but until I have a cheep source, its potting mix already-on-site for this project.

The line I used for these was the 2.4mm star sectioned trimmer line from Ryobi that I had on hand from my mostly unused line-trimmer. This thick, strong and sharp-edged line seemed ideal for stringing these up, bot for stability, but also giving the creeping vines something to hold onto, as well as possible deterring unwelcome mouths.

Below the sunflowers, are a mixture of carrots and onions. Yes,  I know that being root vegetables, hanging gardens will become packed with them, but my thought was to germinate and establish in the hangers, then transfer and replant as needed. All going well, I'll do this in the next batch of bottles we collect.


Next down the stack are daikon radishes.


Again, a big root vegetable that will need to be thinned out in order to get the best crop, but we go through a lot of plastic bottles, and I have lots of surfaces to hang vertical gardens from. One great thing about Daikons are that you can eat the leaves as well as the root, and both tops and bottoms pickle really well, which I hope to do with as much of the crop as I can manage to make successfully.

I strung the bottles before filling them, from top to bottom, knotting the trimmer line as I went and adjusting the tension to ensure that the spout of the bottles pointed directly down to the bottle below. Once filled with potting mix, I poured a quantity of water into the top bottle to moisten it, and add weight to gauge the tension. Some minor adjustments to the knots leveled everything up, and I loosened the cap, just enough to allow water to pour through, without being in danger falling off and washing my soil out.

After a few days of hanging and watering, without any catastrophic failures of bottle, cord or lids, I got the family together and we planted the seeds.

You can see in this shot that the sunward side of the bottles have developed a lovely green moss carpet, and there is a clear divide between the dry inch on top and the moist lower soils, even after 40oC days of summer sun here in Melbourne. This was a big test, and I'm pleased to say that not only is there life in these hanging gardens, that the system is sound. I only water the top bottle, every other evening or so, and each bottle below gets its fill, from the dribbling through from the bottom above.

The water than comes out of the bottom bottle is brown and peaty, so i know i'm loosing some nutrients along the way, but its hardly worth worrying about at this scale. I have a number of bottles of carp-based fertilizer  to bolster my crops, when it comes time to do so.




Here is the crowning (can you say this, when it's the bottom rung?) jewel of our hanging gardens, the peas.

We've tried growing sweet peas in the front gardens for the last few years, and have managed the sum total of three pods, before snails, slugs and possums have killed the plants. This time it will be different!

Our hope is that the peas will climb up the cords, and give us five sets of four cords worth of climbing pea-laden vines.

All in all, this was a really good project, the kids love looking at it, it made use of useless space, recycled materials on hand and otherwise being thrown out, and will hopefully start putting food on our plates in the next couple of months.

More planned, possibly with other crops, and I also have an old cargo strapping net to use as a watermelon vine trellis!

Review: Chicken nipples

No, there's no great punchline here ... just .... chicken nipples .... or perhaps better to say, "gravity-locking beak-activated water dispenser". Either way, these are some very cool additions to my urban homestead that has dramatically improved the hydration levels, and water quality that my chookens are getting.

These valves are sold by  the chicken keepers supply company CC Only as a part of their extensive poultry supply catalog. They have a wide variety of poultry farming supplies, but these little watering devices caught my eye after a post on the American Preppers Network.

The magic of the valve are the twin pins and ball bearing between them.

When screwed into place with the threaded end, the ball bearing and top-pin presses down on the top of the bottom pin, forming a seal. When the bottom pin is jiggled, it moves the ball bearing, breaks the seal, and allows a dribble of water to flow. Once the jiggling ceases, so does the flow of water.

The bottom pin has considerable freedom of movement which means that the chookens can poke and peck at it from whatever angle their little chooken heads come at it.

 In fact, within minutes of placing these out for ours to drink from, they had worked it out and have not gone thirsty since installing them.

This layout was my first iteration, which featured a simple clear bucket, without even a lid, but it did allow me to judge how much water was in it, to guage any leakage, as well as how much the chookens were drinking.

One of the things CC Only were quite clear on is ensuring that the connection was secure.

Drilling a hole in the bottom of the bucket was simple enough, and with a dab of pipe-sealant to close any gaps, the system was pretty easy to set up. The real trick is to ensure the hole is the right diameter, there is adequate material for the thread to bite into, and sufficient sealant to prevent dripping.

I have just recently replaced the plastic bucket with a repurposed baby-food tin with a lid, to stem evaporation and also to reduce the weight , as this big bucket got quite heavy to haul when full. Working with a metal base added a little more difficulty in the fitting, as it wasn't as forgiving as the plastic, but is a longer lasting solution.

These were a great addition to my urban homesteading venture, my chookens have had un-fowled water (hyuk-hyuk) and I think they are a little more entertained with having something to peck at for their water.

Home Front: Pot Belly Stove restoration

One of the small victories I had in my separation of assets proceedings was to gain custody of the dismantled, rusted and pieces-missing iron pot-belly stove. I lugged it back from the house in the hills where Triceratops Girl lives, and back to my place by the bay. When I first moved into the house in the hills I was delighted to find the stove in the midden-heap of a woodpile on the property, and dug around to find as many of its parts as I could in the leaf-litter, mulch and dirt. It turned out to be missing the top pot-lid cover, and the internal base, and possibly an ash catcher, as well as the chimney pipe.

The first problem with restoring it were the bolts that were to hold the "chest" the the "belly" parts. These had rusted solid, the nuts on either side all but fused to the metal of the bolts. I hit these with lots of silicone spray, and set at them with adjustable spanner and pliers, until i was able to shift them within the bolt-holes.

They wouldn't come free, hoverer, so I applied the NASA technique of percussive maintenance and hammered the bolts free of their heavily rusted nuts. This allowed the "belly" and "chest" to sit flush once again, for the first time in a long time I expect. The door moves freely and latches happily, giving a good seal, so I didn't feel the need to do any adjustments to it. The "lid" piece was missing its "pot-lid plate", which I will endeavor to replace with a close fitting disk of steel at some stage, if I can't find a more original piece of stove-lid iron. In the mean time, an old baking tray closed the hole for firing-up purposes. You can see there is a crack in the iron at the base of the stove-pipe, which leaks a little smoke. Perhaps brazing could patch that, we'll see. Using materials on hand, (baby-food tins and some coat-hanger wire) I fashioned a rude chimney,

A second round baking tray was sacrificed to close the bottom of the "belly" enabling a fire to be built within, and given the rough-fit, also acted to ventilate the stove, giving it good clean burning capability, without raining ash, embers or sparks onto the chopped wood stored below, between the "legs".

All in all I was very happy with the salvage, rebuilding and cobbled together spare parts that I used to turn a pile of rusted metal parts into a functional, cheerful and rugged wood-burning stove that can warm and cook for my family, if ever the electrical and/or natural gas grids should fail. It is also small enough (and nests) that it could conceivable be taken along for long-stay outdoors adventures.
