Thread: Hole cutter
12/01/2019 21:12:26
Posted by vintage engineer on 12/01/2019 20:41:22:

I would drill a hole down one side and use a bandsaw to cut out a 3" billet then bore the rest out.

Not saying it couldn’t be done, however i once made a pair of motorcycle fork yokes from 1 -3/4” ally plate and used a bandsaw to rough them out, straight cuts was slow and hard going, tried dry at first, but then used WD40 and eventually paraffin as a lube, but even then the blade clogged constantly, wouldn’t fancy the job through 6” on such a tight radius.

Forget using a hole saw, no way is it going to work.........don’t beleive me ? Try putting one through a 1/2 “ ally plate and then decide. Ally is nasty to stuff to holesaw, even with parrafin or similar as a lube it clogs the teeth, this in turn generates heat and creates drag, which then puts enormous strain on the motor.

It may waste a lot of material, but reckon your only answer is to bore it out, personally would have bought thick wall tube in the first place. If you cut the bar you have into short lengths and sell it on ebay, you should get your money back and probably make enough profit to buy a length of tube.

Thread: what solvent cleaner to use?

Its good to warn people if something is a problem, but the Brake Cleaner + TIG link does not sound right.

Brake Cleaner is a mix of methyl acetate, hydrocarbons like petroleum spirit and around 50% acetone. It is formulated to be moderately 'safe' in use and contains no chlorinated solvents.

To make phosgene COCl2 you need a chlorinated solvent and heat.

I use Brake Cleaner a lot.

It is quite an old article 2009, and American, so maybe things have changed or they use different ingredients in their brake cleaner to over here.

He shows the aerosol label in the article and it contains Tetrochloroethylene.

I suppose the message is, whatever you use, read and the label.

Slightly off topic, but to those using brake cleaner, be careful if welding after cleaning. There is an article online somewhere by a chap that suffered serious health issues. He used brake cleaner to degrease a part then TIG welded it.

Could be the Argon had something to do with it, i cant remember, however Phosgene gas was produced, which is what did the damage.

Edited to include the article :

Thread: Crankshaft repairs

Thanks for the contribution Will, very informative. It is indeed a K series engine, ‘34 KSS. Progress has stalled slightly due to work commitments, and dragging home a ratty J&S 540 surface grinder which has meant some fettling and re arranging the workshop to fit it in.

I will update the thread as and when any progress is made.

Thread: Modern efficiency !!!!!!!!!
19/12/2018 21:56:12

Haha, all this moaning about new technology, and extolling the virtues of simpler times....yes old stuff is cool, but new stuff is infinitely better.

For example 20 years ago i could service my van on the drive, but it wouldn’t pull the skin off a rice pudding, was rattly, uncomfortable, had candles for headlights, did 20 to the gallon on a good day and was generally crap.

In comparison the current van has things under the bonnet which i dont even recognise, but has 204bhp, stops on a sixpence, is quiet and comfortable, with headlights that light the future, does 35 to the gallon and is generally fabulous.

Would i swap for the old one.........err let me think about that for a nanosecond thinking

Yeah, system version of the isar, same boiler different dress.....worst boilers ever made !

Good business for us repair men though cheeky

Martin, I don’t blame you wanting to shun modern technology,(condensing boilers); we had a condensing boiler fitted in the year 2000, it lasted 14 days before its first breakdown, a blown circuit board. Repaired under guarantee and over the next ten years it managed to eat a total of eight circuit boards, the boards cost about £170 each but because I was quite persistent in lobbying the manufacturer about their poor quality of components I managed to get all eight replaced fee of charge.

Dave W

Ideal Isar by any chance ?

I've managed to servive with a boiler and radiator valves and a pump why should I have stuff I've never needed.

Martin P

Yeah My Grandad managed perfectly well with a horse and cart until he got a truck........cheeky

The truth is, since we signed up to the Kyoto agreement, the focus has been on energy efficiency, so the government decides what criteria needs to be met when a new boiler is fitted. Therefore you or i don't have a choice in the matter.

Very interesting!

Our 1973 cast iron boiler must be approaching end of life. (Its had a few thermocouples and the pump impellor has needed reshimming once or twice, so it's a bit like Trigger's broom!)

Is it possible to buy something similar, still, without the complications of condensing, pressure tanks and the like?

All advice gratefully received


fat fingers again!

Edited By Howard Lewis on 18/12/2018 18:28:33

Sadly not Howard, all gas boilers must now be A rated energy efficient, which means condensing. The latest building reg's also require the fitting of smart controls, with either load compensation or a flue gas recovery system in place

You can still run them on open vent, however i don't know why anyone would want to, it's a rubbish idea......Best thing to do with a 70's system is junk the lot and start from scratch. Benefits would include a much warmer house, and annual heating bills reduced by around 30%

I have found a motor and cartridge set.

I assume that I just have to:

Isolate mains and water.

Drain out using valve on right of boiler + hot taps.

Unscrew the valve cartridge from top of diverter.

Fit new cartridge + motor.

Close drain and refill

Good to go???

Pretty much it.......Make a boiler engineer out of you yet Neil cheeky

If & when you end up needing a new boiler be sure to consider an Intergas

I think there's only four moving parts inside. yes


On the money there Martin, my boiler of choice, fitted around 100 of them so far, great bit of kit.

Need a bit more info, boiler make/model etc.

However generally speaking blown fuses are usually down to pump, or water leaking into diverter head.

It's a Main boiler I think a Combi 30 Eco condensing boiler (not 100% sure of the number)

I can't see any leaks. THe PCB doesn't show any signs of damage.

Irony is the pump is a Grundfoss UP XX 50 which everywhere says is one of the best!

Take the diverter stepper motor head off, Black plastic thing with a 3 wire plug attached ( Pull out the metal clip and it will come off) look for signs of water ingress from the brass diverter body and stainless pin that the motor acts on............if its dry, come back to me. If its wet you need a diverter rebuild kit and probably a new stepper motor.

modern boilers are designed to fail safe to hot water only

Sorry Alan, but that’s not correct

Reckon if it was the bearings, your ears would be the first to know, have encountered a few M300’s with problem headstocks and every one sounded like a bag of spanners.
