Would central heating system flush do it?

It removes the rusty sh*te from old radiator systems.
All the right bits, but not necessarily in the right order.

With my central heating head on, is it worth putting a mangetic filter somewhere inline?

I always chuck a magnet into fuel tanks and jerry cans these days too.

If mine is anything to go by Toby, you may have a long road to getting it clean inside! Probably regular coolant flush with dishwasher/citric acid/Daz is the way to go. It'll all come out eventually :)

Thanks Horace, it's easy when all the tools and a good stock of metal is to hand. I don't half go through it, though! 6m lengths can easily disappear in a weekend.
I did think about a bottle brush, it might work well with core plugs removed. I always used de-ion as well, at least I know I'm not putting a load of disolved minerals in ready to come out and form the kind of sludge we're battling now!

That's a good tip about the Daz, I'll have a go with that Sam. Cleaning fluid was some citric based stuff I got with a Machine Mart parts washer years ago and had left over. Useless stuff really, I wouldn't even bother cleaning a floor with it. For this job where I was just blasting gunk out, it was fine, and I added a dishwasher tab in. The tab is actually quite aggressive and I wouldn't use on ali. I've bought some stuff from ebay to go on with now. £25 for 25 litres, diluteable up to 20:1. I'll let you know how it goes when an axle goes in!

I'm a bit concerned about the central heating flush on ali, Matt. I did toy with the idea - I need to get some, bung a block or two of various grades in and leave it a week. Should be fine on copper, brass, bronze and iron. Mag filter to pop in a hose is an interesting idea...


Work continues on the spot welder, which has achieved 1300 amps and pulls 40 amps off single phase mains. Still not quite enough, but does put nice welds into 2 x 1mm plates, which is enough for the bulkhead.  I'll pop a post in the Crazy Contraptions thread when I'm ready to do a write up.
Converting the V8 to viscous fan is going well too. As the water pump is way below centre of the rad in my setup, though not far enough so to add a pulley just for the fan, it's required some creative thinking. I've devised a low profile Z section V belt setup driven off the water pump nose to drive the fan, which is housed on a bearing mounted next to the water pump pulley. It's rather neat if I do say so myself.  A crank driven hydraulic gear pump with electric clutch is in the works too, and a capstan bollard has been delivered ready to mount to a Lofrans gearbox... But that's all off topic and deserves its own threads.... All in good time! :)

Work stopped as I had a cambelt to do on the Audi (what a pleasure German stuff is to work on) and I'm now packing for a little trip up to Callander in Scotland. Quotes are out for cutting and folding chassis, so hoping to be able to place an order when I get back. Very excited!

Sorry, I'm not very good at updating the thread, am I! Visibly, not much. And I've got sidetracked messing about with Sankeys.... I've got the front axle stripped, painted and have a bunch of shiny parts to build it all up with new bearings, brakes, swivels and seals. I've sourced a six pot bulkhead which is in good shape apart from the footwells and managed to find some replica footwells from Catmint, complete with all the correct ribs, stiffener plates and everything.

The engine is seized so solid I can't even move it after having got it moving reluctantly once already. I had heated it thoroughly by circulating hot water through it, so clearly now it's cold, it's not willing to cooperate. The cheapest way I can find to put it right is with liners that Dingocroft sell. Oversize pistons are a small fortune! Finding a decent replacement engine looks like a no hoper too - they all seem to be knackered or way too much money.

The chassis is all drawn up ready to have the sections laser cut, but finding someone who can operate a press brake seems nigh on impossible in this country, so I'm on the hunt for my own.

I'll try and post some pics when I'm back in front of the pc :)

I bought an engine from ebay. Apparently it came out of a fire engine. I figured it was wise to check it over and fire it up, see what's what:

Well it runs... How well is yet to be seen, but nothing horrific has cropped up a far.

You'll be needing a fire engine rear bulkhead for that, dear boy.

I think that's been out of service so long it'll be a shame to use it. Can you not frame it and stick it on a shed wall?

Maybe you should start a museum, Matt?

Could I get tax relief?
