General Discussion Area / Re: Caravan ?

Been looking around for caravans .. thoughts on this one anyone and what to look out for ?

Lunar clubman

 :-\
We had a 4-berth version of that model for many years, luxurious for the time,fully insulated double glazed and winterised, sprung interior upholstery, real oak for the cupboard frames and doors etc.
It would be about the last year to have an aluminium chassis which is great for keeping the weight down but have a good look around the tow hitch and axle attachments for signs of corrosion where steel meets aluminium. They had rubber or plastic material to keep the two metals apart so you shouldnt see any significant corrosion.
The roof is a one-piece fibreglass moulding which was unusual for the time, result is very unlikely to have leaked from above. Any leaks and rot would be below windows.
The rear push/pull/curse_swimbo handles are missing, this would suggest some dampness and rot behind the rear panel, quite common in a 'van of this age but easy to fix with basic woodworking skills and modern polyurathane glues.
The floors on these were some of the very first laminated ply/polyurethane foam/fibre board construction and early ones suffered from delamination just inside the doorway and by the sink. Can be fixed by drilling holes and injecting resin but best avoided.
Axles were by Knott but usually had Alko hubs and brakes so spares readily available.
Budget for new (reinforced) tyres.

Sorry mark she went to a fellow disco nut ...

Thanks for that Bertie, we have enough work on at the GCR without<him> inventing more for us to do.

There always going to bang when your turning a bloody great big magnetic coil on and off like that lol.

Still, it gets your body 'back into alignment' (all be it for a fraction of a second!)

Nope...the magnet is on continuously which 'pulls' all your atoms into alignment with the magnetic field;  we then blast you with a massive pulse of RF which deflects the atoms slightly out of line with the static field (and creates the noises), at the end of the RF pulse the molecules re-align with the static field at a rate which is characteristic to each molecule and release energy as a weak RF signal as they do so.
Very sensitive RF receiving coils detect the energy released and then it is up to the computers to convert this into an image representing body tissues or a display of molecular types and concentrations within a particular part of the body.

If you twiddle your tip daily as you are supposed to then it doesnt get stuck. Is your end glowing red?

The thermostat works by magnetics, it is attracted to the tip closing a switch. As the temp rises above the curie point the magnetic attraction is overcome by spring force and the contacts separate. The tip and thermostat on your iron are probably stuck together by rust or corrosion so the contacts are closed permanently.

These irons were common in the 70's but be careful using them on modern high speed / low voltage electronics, they create a massive emc pulse when switching and can destroy small geometry parts. We used to use them for finding holes in the emc protection of fibre receivers.

The pipes inside will be solid so no need to replace.
If the heatshields have come loose and are rattling you could put a jubilee clip around each end to hold them in place.
If really rotten then cut them off and wrap the down pipes in an exhaust heat-shield bandage - lots available on the bay- this keeps the heat away from the bulkhead etc and reduces the noise level. Got to say that this is best done with the pipes unbolted and lowered down though, nigh on impossible in-situ.

You may find some 2.5/3l pipes in good condition but would have to fit another lambda boss after the main cat to fool the ecu.

Omega General Help / Re: Easy start - diesel engine?
« on: 11 February 2014, 22:11:48 »
I'm sure Mr DTM will be along in the morning to explain the evils of using ether/easy start, if you are lucky he will just post pictures of a damaged piston and bent conrod but I would be putting a phone book down the trousers in case he is in a bad mood.

Nothing wrong with the accurately metered ether delivery systems fitted to some commercial and construction vehicles to aid cold starting, its the hand-held spray cans that do the damage.

Er..you can open a new account with GiffGaff and retain your old number but as far as I know they are separate companies so no direct 'transfer', GiffGaff just pays to use the O2 network.

Pedal catching on floor covering or the panelling above feet?

Its a hydraulic clutch so first port of call has to be fluid level in the brake/clutch reservoir.

Happy Birthday Mark.

What prezzies have you got?
  A centre car for the DMU?
  Or a nice new set of engines?
  Or none because of past misdemeanors?

« on: 02 September 2013, 16:38:26 »
The obvious solution is to re-site Mrs DTM's tumble drier and Mark's work bench to the side wall of the garage then demolish the garage end wall (TB can organise that) so that a mini digger and dumper can drive straight through into the back garden.

Or alternatively, can easily sort that for you.  :y

I think Mark has some off-cuts from the buffer beam off the DMU....could tack a bit of that across the hole. :)

« on: 12 November 2012, 20:20:44 »
Agree with the comments re 1.4 petrol, needs to be driven hard but OK once up to speed.
The Meriva and Zafira are cars you need to try before buying, there are huge blind spots at the front due to the screen pillars, some people can compensate for this easily and others never get the hang of watching for traffic when entering roundabouts etc. Still prefer them to the Renault Scenic & Espace which have a really odd driving position.

General Car Chat / Re: For Sale: One slightly used tow pole
« on: 12 November 2012, 18:58:33 »
TB, that poles not nearly bent enough. Lend it to MDTM, he does a proper job on them.

I like the ones used by RAC, 8 foot long and seemingly solid steel.

« on: 03 September 2012, 23:05:33 »
Ooh, sounds like they've lost a sheep in there or sumat. Bit of a rattle...?

Quite a small engine by todays standards but when the first one was being assembled at Barnoldswick no one could believe the size of it. (think it was 9 foot diameter)
The fan blades have quite a bit of clearance between them and clatter about due to gravity when spinning slowly. At working rpm however they bend forward and each blade locks onto the next one forming a rigid disk.
I have a piece of an early blade root forging, passed down from my dad. It is some form of titanium alloy, been used as a dolly, an anvil and all sorts over the years and is still polished and doesnt have a mark on it, files wont touch it.
