A project that I've started working on recently is to restore this old His Masters Voice AM radio that I've acquired. This is a big difference to what I've been familiar with and have been working on so it should be an interesting project.
This is what I've got to work with, the cabinet could do with a bit of work. Some new varnish, new speaker grill, etc. but for starters I'm going to work on getting it functioning, then get it looking pretty.
The valves all seem to be in good enough condition after cleaning the dust and filth off them.
The chassis is a bit rough looking, but apart from some wires with failing insulation seems to be in good enough condition. There are no obviously damaged capacitors so this could be a goer.
I ended up plugging this in and to my surprise, the tube heaters started to glow, there was a faint smell of hot dust and the speaker slowly came to life. After that initial proof of concept I wanted to replace some of the wires with faulty insulation, having done that the speaker now no longer sounds and it smells a little hot, though that could just be normal. Not sure yet.
Unfortunately as I need to move house soon I've had to shelve this project. I've put it into storage at the new location and will track down the fault once I've been able to get a work space set up for electronics work.

Sometimes a job comes up that needs to be done and the quality of the work doesn't need to be that high. A perfect example come up over the weekend, I'd pulled out the spare tire in the little Mazda 121 to clean the boot nice and thorough cleaning and I found this:
It turns out that water's been leaking into the boot and collecting in the spare wheel well causing some minor rust. To stop this getting any worse and causing major problems I decided to put some fresh paint on. If this was a good car the way to do this would be to pull all of the plastic out of the back, mas off what can't be removed and paint with a white topcoat.
What happened was a quick wirewheel of the rust to remove the flakes, then a couple of coats on undercoat. Then a couple of coats of a silver topcoat that happened to be in my paint store. In the end it came out pretty good I think.
The colour doesn't match perfectly and there is some overspray if you stick your head right in. But there won't be any problems with the well rusting out for the rest of the lift of this car, and that's all this job was about.

So we've been having some trouble with the Land Rover.

So this is probably going to end up as a bit of a rant, so fair warning.
For many people, there is some almost mystical aura surrounding 'DIY' projects, almost as if having built it yourself is the pinnacle of human endavour. As if having the thing for the sake of having is rendered moot by having made it. Which is fine. There's a lot of things that I would like to make, not for any practical reason, but just so I can have made it. But that's where we differ (I think). There's a lot of things that I would have if I could, even if it meant buying them. Because, although there is something viscerally pleasing in having "made it meself", it's generally cheaper to buy it.
I don't mean cheaper in terms of dollars and cents paid out of pocket right now. I mean cheaper in terms of time, of stress, and these things are the trade-off of DIY. When you choose to do it yourself, you are choosing to trade your time for your money. The big expense (at least in this and most developed (are they called 'advanced'? I forget the politically correct term) countries) is labour costs. Most of your money spent on products goes towards paying the wages or salaries of the people producing it. (If you will permit me a small segue) especially in a country such as Australia, where more and more people are working in the service sector, because that's where we have a 'relative advantage'. ie. that's where we can do it better than others. The trouble is that we need more than just services to have an effective country, which is why Australia is so dependant on trade. We trade our services (and natural resources like coal and iron ore, where we also have a comparative advantage (this time for physical reasons: we actually have iron and some really quite good coal)) overseas for money, and use that money to buy the things we need, often manufactured from the very materials we send over there.
Where was I? Oh, right salaries being the cost. So, when we DIY, if we want a similar or better result than a professional would give, we normally need to use at least the same cost in materials (there are some variations, eg. maybe you won't break as many tiles as a pro in a hurry, or maybe the tradie can get a better deal). So the only major difference is in the cost of labour, which really boils down to: do you want to earn the money at a 'real' job, to pay someone else to do it, or do you want to have a crack at it yourself, spending probably more time on it than a pro would need, but saving the money you would have spent on them. The problem is that oftentimes, the reason someone else gets paid to do it, is that is sucks to do the job. Think digging ditches. Through granite. By hand. It's not blisters that are the problem, it's the fact my arms are about to fall off. But, my time is effectively free (monetarily) as I'm currently unemployed. So that's where that equation balances out.
The other reason for doing something yourself is if there's no way to actually buy the thing you want, and this is why I want to build boats and miniature trains. For the boats, I don't know of anyone that sells a non-plastic car-topping dinghy that one man can handle, including getting it up on the car, and if they did, it would probably be prohibitively expensive, because of the time it takes to build such a thing. For the trains, again, I don't know anyone who would build a 5" gauge 1.5" scale 4-truck Heisler for anything like the cost of the materials (again, for both examples labour is the major cost).
But the reason I find most compelling to go your own way, is in the enjoyment of the build. Now, this is a tricky subject in many hobbies, I think because people forget, or just plain don't know how to look from the other guy's perspective. And the truth of the matter is, no one opinion is right, except perhaps for the person expressing it. Some people enjoy the building much more than the using, as evidenced by the number of model train buffs who will build a new home layout every few years. Some people enjoy the having, as shown by the people who collect models, and trawl garage sales for that one find that they will give pride of place. Still others enjoy the using, and they can usually be told by the work-stained, but ultimately servicable boats that will cruise around, and rarely miss stays, but are likely to get scorned by the 'gentry' for being altogether too scruffy-looking. The key thing, though, is they all share one thing in common: they all enjoy what they're doing, and keep doing it for that sake.
So all it really boils down to is this: When choosing to buy or DIY, consider your options, your reasons and then make a descision. Just never forget, that because you want to give it a go can be a good enough reason all on it's own.
