Tonight Matthew, I am sewing machine repairman…

Sewing machines… They work by magic, don’t they?

My daughter has been using my wife’s machine to make clothes and bags from old unwanted material such as pairs of jeans and shirts that I no longer fit into:

Unfortunately the machine had somehow gone wrong and had no tension on the upper thread at any setting of the tensioning wheel. Peering in though the gaps in the “bodywork” it appeared that the two discs that are supposed to drag on the thread to produce tension weren’t even touching. After a discussion in which we decided that it would cost more to have it serviced professionally than it would to buy a completely new one I decided I might as well take it apart and see how much damage I could do. There can’t be that many “ping-fsckits”[1] inside, surely?

We found a service manual online that explained how to remove the case, but having done so I couldn’t work out why the tensioner wheels weren’t working correctly so I decided to remove the mechanism for a closer look. At which point it exploded into a pile of springs, discs and washers. After at least one false start I managed to put everything back together and realised that the tensioning mechanism was now working correctly.

Right in the centre here is the tensioning mechanism in case you’ve not seen one before.

I have no idea why it’s now working and what problem has been corrected which is quite irritating given that I therefore have no idea how to stop it happening again, but I’m happy enough that it has saved me a packet which I can now spend on an Oxalic Acid vaporiser for my bees 😀

All I need now is a suitable spring balance so I can correctly set the tension range.

More seed sowing today. Red (I also have yellow) beetroot (Sanguina) sown four seeds to a cell in a twenty-cell module tray and a couple of similar trays of peas for shoots sown four seeds to a cell — I’d normally sow three, but the seed is a few years old so I thought I’d sow an extra one “for luck”. There were flowers in the plan for today too: Lobelia, which has the tiniest seeds ever, and Busy Lizzies, both for my wife to plant out in the garden. I sowed a tray of each, leaving sufficient seeds for a couple more sowings over the next few weeks. They’ll go into the propagator once they’ve had a decent soak.

A blast from the long-distant past

Back when I was at school (slates, chalk, that sort of thing, you know…) the BBC Micro was a thing: one of the first home computers, based around the 6502 processor. Quite likely it’s responsible for setting the future direction of my life. I spent a huge amount of time messing about with them in my teens, writing software both to earn myself some spare cash and for things at school.

Move on several years once x86-based PCs became affordable as home computers and with the arrival of Linux I decided to write an emulator for the BBC Micro running on Linux under X11. It actually worked reasonably well at the time; enough to play some of the original games I’d enjoyed, certainly. Even now I recall sitting in my employer’s office in Palo Alto after work when I was there to do some training or something similar, designing fonts for the teletext display mode. Here’s a random selection of screenshots…

Anyhow, I was having a little grub around in my filesystem the other day and discovered the code again, so after adding some CMake build files to take over from the original Imakefile system, I’ve uploaded it to github. Sound doesn’t work any more because as far as I recall it used ALSA, but I’ll see if I can fix that in the coming weeks and perhaps make a few other improvements too.

Memory Lane, 3rd April 2022: Green Onions

Booker T and the MG’s, isn’t it, pop-pickers?

Well, perhaps 🙂 Two years ago it was time to be planting out my onion seedlings. These had been sown on the 8th February, four seeds (ish) to a cell in module trays. Hundreds of them, because we eat an awful lot of onions.

More chippping of apple tree prunings today. Nearly all done now, and would perhaps have been completely finished but I was too lazy to go and buy more fuel. Once that’s done I can chop down a few more sycamore trees to make even more 😀 They’re in the way anyhow — two are alongside the workshop and have been rubbing against the roof whilst a third is leaning over the garden at a rather disconcerting angle. I may have to start spreading the wood as I chip it fairly soon because I’m running out of dumpy bags to put it in. I’ve started on the eighth already and don’t seem to have that many left.

No dig diary, 2nd February 2024

My plan for today was to finish feeding all the brash from my apple trees through the chipper so it was all ready for making my flower and strawberry beds. I managed about half of it before some bits broke off the end of a branch I was feeding though and got jammed in the cutting drum of the chipper. Whilst the drum would still rotate, it wouldn’t go anywhere near as fast as the engine wanted it to so I had to kill the engine quickly before the drive belts turned to smoke and flame.

After dragging it back to the workshop I had to remove the hopper and (whilst wearing gloves, because the knives can leave you with a nasty cut even without the motor turning — don’t ask me how I know; I just know, ok?) clear all the trapped lumps of wood out of the cylinder the drum rotates in. I was particularly pleased when I offered the hopper back up to the chippper body (balanced on a couple of sawhorses because of the weight) and three of the bolts slipped right through the mounting holes allowing me to get the nuts on and keep it in place whilst I hunted for the final bolt in the mud where it had fallen.

A quick check that the engine was now happy and it, err, started to rain, so I abandoned the rest until tomorrow. It’s amazing how often it rains when the Met Office says there’s a five or ten percent chance of precipitation. I guess they must be one of those groups of people for whom one in a million chances happen nine times out of ten.

Memory Lane, 2nd April 2022: Attack of the giant beetroot

I think this must have been in one of the veggie beds for almost a year. It reached the point where I decided I couldn’t pick it and just had to leave it to see how big it would get. By the time I finally removed it from the ground it really didn’t look at all appealing to eat. It’s in a “mushroom tray”, which if I recall correctly are around 40cm x 30cm, or about 16″x12″ in old money.

3d printing for learning to play the violin

Who knew? My niece is learning and her mum asked if this could be printed to help her with hand positioning. It’s a bit “stringy”. Put that down to old (and cheap) PLA.

Apparently the idea is that the octopus is placed on the back of the hand and the pupil has to keep it from falling off whilst bowing, so no rolling from side to side or anything like that.

I’m not sure what Nigel Kennedy or Vanessa-Mae would make of it, but I guess anything is worth a go if it means there’s less chance of sounding like you’re strangling a cat.

Memory Lane, 18th March 2022

As I’ve just posted about sowing broad beans I can remind myself of how they were doing a little over six weeks from today, two years ago. I’d just planted them out.

I can’t for the life of my remember why I put these mesh cloches over them though. It may have been so that I could cover them with fleece in the event of a likely heavy frost without damaging the plants.

There appear to be around 20 plants here. This year I’ve planted far more on the grounds that there never seem to be enough that are ready to pick at the same time and leaving them until there are enough means we end up with much larger and tougher beans.

No dig diary, 1st February 2024

I’ve ended up somewhat behind with stuff this Winter. Before Christmas my daughter and I both developed an ear infection that totally messed up my sense of balance for about a week and a couple of weeks ago I had the pleasure of a particularly nasty bout of cellulitis. I don’t really recall anything about the first forty-eight hours of having cellulitis other than vague hints of wittering randomly about stuff that really can’t have made sense and quite possibly didn’t actually happen 😀

Anyhow, the cellulitis meant I wasn’t really on the ball when we had some tree work done, including felling a sycamore that was leaning over some of the outbuildings. As a result I only finished clearing that part of the brash that was blocking access to the veggie plot yesterday, by feeding it through the chipper. I now have four and a half dumpy bags full of woodchip that will come in handy when I remake the paths in the veggie plot shortly (and there’s more to come).

Today therefore I got into the greehouse and sowed lots of broad beans (Aquadulce Claudia) and a first batch of antirrhinums (Lipstick Silver and Black Prince). The latter are to go into a bed of flowers for cutting later in the year (not least because the only place the bed exists at the moment is inside my head). Had I been able I’d have started the beans off perhaps a week or so ago, but thems the breaks.

I also had a bit of a clear-out and reorganise in the propagation greenhouse. I had a dozen and a half tomato cuttings that I’d successfully grown on from my father-in-law’s F1 Orange Paruche plants last September, but a particularly cold (for us, at -6°C) night saw them all killed off. My fault. I should have been more on-the-ball, though it may have happened when I was suffering myself. Those went into the compost along with some plants I’d kept after doing some test germinations before finalising my list of seeds to buy last November. They’d become all rather leggy due to the lack of light (it’s been a very dull Winter, weather-wise). So now other than my newly-sown seeds, all I have is new strawberry plants that I had to pot up because the new strawberry bed doesn’t exist yet either, and peppers/chiles that I grew last year and thought I’d leave to see if they’d make it through the Winter in the greenhouse. I’m not too hopeful in that respect, but we’ll see what happens.
