Awesome write-up Alan.

That's great George.

I have wondered why people keep jumping to steppers and fancy tech. Those of us with model railways probably prefer a simpler way forward.

Dave Sawdon - the 18B is a new "hot" model - how about a review?

I am enjoying Blondihacks a lot at the moment. Plenty of goofs and ways to get out of it.

Ade's Workshop is gentle stuff, he seems to like doing things his way which can be refreshing.

Keith Appleton is also enjoyable and relaxing from a chat point of view, He likes the easy way to do a job, which I can't complain about.

Joe Pie seems a little formal, I think I may have been spoiled a bit by the above crew.

Metros where OK

I learnt to drive in one, my instructor had a mini first, then upgraded to the new Metro. It had appreciably more space and a bit more comfort. Neither had enough power or gears and they where noisy, but all small cars where heavily compromised in those days.

The 80s where a time of great development in cars, we don't remember how fast cars where improving because we have become used to the amazing things we have now.

All good stuff, I love a bit of Dambuster history.

there is some Grand-slam stuff on Wiki too:

That is so tempting.

Dave, the incoming air does work against atmospheric pressure, which is in balance, so the outgoing air floats in the in-coming. Its more like moving a counter-weighted lift than moving the load on its own.

Its really a viscous flow problem, not a potential energy one. It would be interesting to know if your answer is anywhere near correct, it could make a good rule of thumb.

Great point Speedy Builder 5. The problem of moisture-laden air entering cold properties is a common one in historic monuments and can cause mould. The solution of drying incoming air (Air conditioning) is getting popular where budgets allow.

Dave SOD, what has lift got to do with it?

Fresh air will replace the air you pump out.

Found it! or at least a brochure from a potential installer. I can e-mail it if you want.

The Monoblock units are small and cheap so more suitable for our house, LG do split units too.

Its a fast-moving field so I expect to repeat my investigation.

One of the important things I learnt was that you can't get a grant without a proper energy survey by a qualified engineer. All the salesmen would quote a lot and hope that the survey didn't come up with any problems.

It might be worth both of us getting a consultant to do a survey to lubricate negotiations.

Hi Steve, no we didn't go forward with the system, we didn't get a warm feeling from the people who contacted us, I got some quotes via a company advertising on Facebook called Greenmatch and I was sure they where high. Its on the cards for next year though, probably with a local company.

My house wasn't designed to have services other than a gas fire and cooker, so it has to have pipes and radiators, I am jealous of those who can use nice, simple, air.

I recall that the LG unit gives a good COP at cold temperatures, when other gasses stop working. I am sure they all have poor COP at high temperatures too, gas boilers simply do a better job.

I don't know where I have the brochure or in what form, memory playing tricks again, it doesn't help that the heating paperwork has been tidied away. I thought they sent me a pdf but its missing.

Hi Jon

Another rescue job I see, you are a sucker for anything in need of love.

I am enjoying it so please carry on posting. I like small and manageable engines.

All good stuff, especially the comments about dew point.

1/2hp seems far more than you need, work out the capacity needed from changes per hour, 3 or 4 will do, more is for cooking or puddles of groundwater etc.

I have bought one of these for fume extraction, I still need to get it installed pulling through filters so I won't over reccommend it until it proves itself. Its worth noting that the biggest is only 120W. There is a size calculator on the page to the right.

Hi Steve

A recent innovation is R32 refrigerant, which is better suited to to our climate and makes the LG system highly attractive. I don't know if the competition are catching up yet.

My Mrs is completely sold on electric heating. I put in a wood burner with back boiler about 12 years ago, always intending to hook up thermal tubes to the bespoke multi-coil boiler, but never got round to that, or to having a gas boiler to warm the house when we were at work. After all those winters messing about with logs and probably getting lung cancer she is ready to rip it all out. I am crying inside after all that work, but our work and health have changed with age, we need a warmer house, and the technology has moved on.

We got a load of quotes last year - most where 14k - obscene! One of the issues was the government green skies subsidy, which doesn't like alternative heat sources, even when they are a no-brainer like solar thermal. So if you want the government to chip in then you will have to play a bit of a game.

I would be very interested in anyone's experiences of Air-source and solar thermal too. The posts above are most appreciated, ta.

Ta Stevie and Brian - all going well so far.

Hi Frank!

That looks fabulous Vic.

The Movers quoted £1000 to move my little mill, so one of these would be plenty.

Put a DTI on the head and touch against the bed or visa versa and pull down on the head hard - what happens.?

Its worth noting that you can get adjustable gas struts, if you don't know the weight of the head for sure you could fit one, and bleed it down until the backlash disappears.

All of this is all very well but it does rely on all your operations having the same direction of force and clearly drilling is the issue here.

Engine cleaner would be a good start, wash off as instructed, then a volatile solvent like meths or acetone to get rid of the wash, especially if its water.

White spirit leaves a little of its heavier elements behind, you might find that they will come off with meths and leave it clean.

As I found when working with printing ink, solvents just dilute dirt so you need to wipe it off and repeat endlessly, a detergent binds to dirt and is happy to be washed off.

I have to agree with the moderators.

My "main" forum is the Unofficial Mamod. It has remained peaceful and harmonious for more than a decade due to ruthless moderation of anything hurtful, even to numpties. It has a large membership with strong contingents from the USA, the EU, especially Germany and Australasia. The potential to argue based on various actions in British history is awesome, but nothing is ever said, it is a place of steam heaven.

Facebook on the other hand is full of bile and bitterness. That is the place for politics, or Twitter.
