I have a cunning plan for the old bottle

Jeepers that has taken me back about 60 years squeegeeing the gloop through a screen with a rubber wiper thing and then etching it off . I didn't realise that was still carried out but I guess it's all digitally controlled now.
Just realised it was all digital then ..............we used our fingers!

@MetalMonkey's method is the one we use.

The way I used to do it was laser print the design on an acetate sheet, then lay it over the board, UV expose it, then straight in the acid etch tank - and that was old-school twenty-odd years ago!
Obviously only good for the odd small job on a single layer board, but handy if you need to knock something up quick, or prototype - anything serious we would send out externally to be done.

Same here, a lot of what we do is one off designs and quite often can achieve a next day turn around on the entire system if we need to. You can do double sided boards relatively easily. That's what I've been doing today at the other office unfortunately the ferric chloride has gone weak and the gauze in the tank (proper old school made of titanium) is worn so I've really been struggling with it.

If the etching has been working then it's about 20 minutes to make a board from printing off the transparency to the board ready for drilling. The only thing we lose out on is plated through holes but there are solutions for that.

They won't take the small bottles back so I picked up a big one from marketplace for a tenner and just had to pay for the refill/exchange.

According to what I’ve seen, Calor have changed their minds on this, going to fill them, but not replace or test them when the time comes. So many caravans have locker space designed for them. I could be wrong on this, it could only be propane though.

I was at a Calor stockist today and 4.5kg bottles weren't on the list, maybe it will be updated.

Just had a look on the Calor web site & they say that they can be exchanged at the Calor depot by appointment, this is different from what was written in the Caravan club mag. Calor are a law unto themselves.

We used to use a board with strips of copper at about 1/4 " spacings and already pre drilled at again 1/4" spacings and just scratched out the copper as required. But I bet you already knew that. I forget the name of it now.

It's going to cause huge problems for anyone with a motor home and many boats too.

It already is, a friend of mine has recently bought a Carthago campervan, takes two of the small cylinders in the locker. He’s got over it by using 2 patio gas ones, luckily they just fit in the locker. Don’t a lot of plumbers use them? Or used to, imagine trying to drag a 6 or 13 kilo one up into a roof space.

They have also done away with the 6kilo lightweight cylinder which was a far more manageable weight to handle in & out of a locker.

The thing is, how are you going to make an external access gas locker big enough for a bigger bottle? Especially since every inch will already be used internally? Madness!

My camper takes a single 6kilo, we have been using the lightweight as access is a bit restricted, no longer available, they were much sought after by the caravaners. They were a couple of pounds dearer to refill than the standard ones, but much nicer to handle

Repurposing was obviously what I meant there. Senior moment.

Vero board / strip board. I think Vero tends to be associated with the ones without the tracks these days.

To be honest with the proliferation of surface mount stuff it's a useful bring able to prototype your own boards.

My gfs family recently bought a new top of the range gas barbeque. I noted it came with a Strange looking gas regulator.

It must be related to these new bottles then.

 

[dobbslc]

Seems a really strange thing to do seeing as there must be more campers and caravans around now after covid that holiday at home

I still use strip board quite a bit, although with companies like JLCPCB offering such ridiculously low prices (e.g. for PCBs (as long as you're patient), it's often tempting to just knock a design up in KiCAD and send it to them.

Our main benefit is having the kit to hand along with enough stock and workshop machinery to turn around a prototype very quickly.

One of our best sellers has been adjustable power steering modules for rally cars. The prototype for that was turned around in under 24h which contributed in part to it's success. Similarly a big hydraulic shear went down locally, a couple of days was spent reverse engineering the wiring (actually in advance of this because it was being flaky) but then we made a PCB overnight and got it working within 48h.

Its just a way of working that works for us.

This AC DC Tig welder




Thing is the seller said it was broken. And the price was as such so I brought it home anyway

He was a nice guy and explained the fault was only on the pulse weld side. AC. That in use it started going between say 200amp and 180 amp.

He bought another TIG and this one sat until now.

It turns on etc AOK and I actually can see the AC pulse settings as having been set at 200 - 180 amps. Makes me wonder is there a fault I'll have to test it out this weekend. I bet there is a fault of course just that there is a small chance it could be a setting mix up I guess.

Parts are available from SIP so If I need to I can buy a new control board etc.

A**ebook marketplace find. I don’t do much spraying but have been looking for a replacement to my ancient scrap heap find aerograph. £20, the cup is mine and the front bits are soaking overnight. The needle is plastic?

Stripped cleaned, with some fiddling set up. I had to machine the trigger step on the needle, couldn’t get the air to start before the needle lifting. Tested, works really nice. I’m strictly an amateur, but a gun that does what you expect is good.
