What's the minimum number of steps to connect a Hurricane to a Seven? (Not counting your father!) Jonathan

Have you already got all of the factory wiring diagrams that you need? Could you add a photograph of the back of the speedo? ... but i don't get any power to the gearbox socket green wire. Have you located and checked the fuse? Jonathan

Or members who don't look at Blatchat? We know there are lots of those. And in my experience it's a good idea not to assume that we all look the same way. Jonathan

After many years of nagging I now understand how to work the cotton, wool and normal cycles, where to put the detergent and the fabric conditioner. :-) Not particularly interesting machines, except for: Illustrating how not to design human-machine interfaces.The sheer ugliness of using concrete blocks to keep the drum under control. (What would ACBC have done?)The wonderful Keymatic control system. Jonathan

Spring washer: to lock a thread where there is possibility of a nut or bolt working loose. Not used with a nyloc nut.NASA Fastener Design Manual 1990. That's the one casting doubt on whether split ring washers work. ... Wikipedia on washers. Includes that debate and a brief comment on the effectiveness of wave washers. Jonathan

The large 1/2" plain chamfered washers are often used with suspension bushes. The chamfered edge must be fitted towards the bush to prevent contact with the metal part of the bush. That one has come up a few times. A pictorial or verbal explanation would be an asset to the knowledgebase. Jonathan PS: John Vine's notes on the correct placing of Schnorr washers for the BMW diff.

Wasn't aware of cables that were 'heat proofed' dont suppose you know the supplier ? Private Message sent. Jonathan

My current workarounds: Space them off body text.Leave the URL visible, which I normally deprecate.Consider bold text.Jonathan

I'll order some heat protection sleeving. That will slow the heating of the cable inside but might not affect its final temperature. How about fitting cable that is specified for high temperature? Jonathan

Seems to vary. ... Sean's Bolt List has: SteeringTrackrod end to steering arm M10n/a1.0mmNylock 2534... Jonathan

If you don't want to fabricate the pipework in metal NB some of the silicone hose suppliers will do custom pieces with reducers, outlets etc. Jonathan

Does anyone know how much cable and what colours I need to order, I believe the size is 3mm . If you'd like the factory wiring diagram please send me a Private Message with your email address and the car's year, model and dash. "Standard" British wiring colours. Jonathan

I'd start with VE's solution. Jonathan

Previous discussions of mounts. Jonathan

Thermo Switch Jonathan

If I could find a timer that worked for about three minutes after I switch off the ignition, it would be awesome. ... Search eBay for delay off timer 12V, then you might find something useful. Exactly. I'd restrict that search with "car" or something similar to avoid hits on controllers for domestic plumbing. Let us know if you can't find one. Jonathan

I wouldn't. One of the points of attachment has already failed. I'd strip down the other to be sure that the preparation (as above) and fixing were done properly. ... There's a vast amount on this in the archives, both with methods that only use adhesive and those that use mechanical fasteners. I suspect that failures when only adhesive was used are more likely to have been caused by poor preparation rather than the wrong adhesive. And I prefer a sausage roll to humpback bridges or a sandwich. NB If you choose "Sikaflex" there are a lot of different Sikaflex adhesives (and sealants!). Jonathan

Mudguard flap or whole wing? Jonathan

Explainer, but it doesn't go as far as answering: Does anybody have the make and part number of a water pump with the evap chamber and the cast impeller? Jonathan

That is why trying to keep the experiment simple was important If the "simple experiment" is the one described in #156 it would tell us very little about what happens in a car engine. The time taken for a jar of hot liquid to cool depends on a lot of factors including the convection caused by temperature differences within the fluid. But the heat transfer in a modern car engine is predominantly due to the bulk movement of the fluid caused by pumping not by convection in that sense. The amount of heat stored in a jar of each of the different coolants is highly relevant to cooling a car engine. But other things being equal that's determined by the heat capacity. (In the jug model that's the volumetric heat capacity rather than the mass heat capacity (or specific heat).) Jonathan PS: ... the Mpemba effect was discovered by an Indian school... If that's referring to Mpemba's own observations that was in Tanganyika.

Would not the process basically focus on time to cool a given volume using a standardized cooling process that can be repeated. It depends on what you're trying to measure. We know the specific heat of the coolants under consideration. The *first approximation would give heat transfer capacity as being proportional to that. See the second paragraph of James' comment above or any of the previous occasions on which this has been discussed. Even heating say a liter on the stove to 90 degrees C and putting in the fridge or just leaving it out isde and measure time to dissipate the the heat back to say 10 degrees C. That's a very different setting from what the coolant is doing in a car. And it leads to the fascinating Mpemba effect. Fascinating but irrelevant to cooling a Seven. Jonathan * Beyond that it would be possible to consider the metal/ coolant heat transfer in the block and the radiator (see "wetting agents"), the thermal conductivity, viscosity and density of the coolant, the rumoured local boiling etc. But the between-coolant effects of these on bulk heat transfer are probably small compared to those which depend on the differences in specific heat. And we know that engines using Evans Waterless Coolant run hotter than those using conventional coolant. An adequate model is always going to have to explain that.

I'd ask Redline. Jonathan PS: Discussion of size of the washer.

As above. My first three commercial suppliers would be Redline, CBS and Holden. I'm not so familiar with SVC and will have a look around the site. Jonathan
