What about people who came here when when they were five then commit a crime when they are twenty. What about someone who comes here when they are fifteen gets married has kids and grand kids and commits a crime when they are fifty.

All problems do not have to have the same solution. People with off street parking can charge at home. People who work in places where there is parking could charge there. With average mileage they one have to charge one day a week so 20% of the parking places would need a charger assuming no...

Maybe UJK and others should do some pull out tests with different materials and fixings. It would be interesting to know what the track could take, obviously a lot less than the clamp you show could give.

Thanks for confirming what I have stated.

why not counter sink the channel so you can use longer screws or use a counter sunk set screw. Screwfix sell 3mm X 30mm screws. You can buy counter sunk M3 x 30mm machine screws, M4 x 50mm

The t track will act structurally as a continuous beam. But it is not very rigid so only a few screws either side of the clamp will be fully engaged because the track will deflect. If a flat plate was attached on the under side of a MFT with set screws from the track to the plate to clamp the...

Dovetail slots with no track have the advantage where as you note you can arrange your work so you can clamp against it. They are also cheaper and can be installed quickly. If the work piece is not above the track or dovetail and the fasteners have sufficient capacity (as you note maybe...

The USSR had fully operational tactical nuclear weapons in Cuba which were stupidly under local control. Some of the USSR's submarines that were being harrased by the US navy had nuclear tipped torpedoes which again were under the control of the submarine captain.

A routed dovetail to fit a clamp will be the same profile as a routed dovetail to fit a track in which a clamp is fitted. the dovetail track will have more material above it resisting pull out since it is slightly bigger because you have to allow for the wall thickness of the dovetail track. The...

Last time I looked dovetails have corners in them!. I doubt that aluminum t track would fail at the corners, maybe 80N/mm2 in tension and 50N/mm2 plus in shear depending on grade. Ply has a shear strength up to about 8N/mm2. Wood glue is about 2N/mm2. A clamp with 60mm running in a routed slot...

The rate at which CO2 is being added to the atmosphere is rapid. When it has changed this rapidly before there has been global changes. Very few people expect the climate to change to pre-industrial, that is a redherring on your part. The UK is a trading nation. If the nations we trade with...

They just hook under the MDF. As long as you have about 40mm ish clear vertically under the table you can insert down through the dog hole then turn to the horizontal. Then you need enough horizontal clearance under the MFT the direction you want the clamp to operate. So if you were to support...

The thing about extremes of weather is that they are distributed on a bell type graph. In the long run the extremes will happen by chance. When you shift the bell curve to the right, by putting more heat into the system the chances of events change. The odds of some events happening go up so...

Things aren't suddenly going to go to pot it is most likely to be like the lobster in the pot. In the UK we will likely get more heavy rain, storms etc to some people will be flooded and everybody will pay more insurance and tax. Some plants will die off because of the hotter summers and new...

Many things including tools are not used to their full potential. Often different people use different features. I don't think that means that there is anything wrong with the tool. I have not used a MFT yet nut what surprises me is why they are not used more to cut angles. 45 degree is obvious...

You missed out trains, which are often faster than flying now up to about 500 miles. Airships are a bit slow but could be good for getting to islands or crossing to France. If they could load passengers whilst attached to the top of a tower they could be used to get directly to a city centre or...

The deserving poor are the people like you; the undeserving are the rest.

bring back lead paint on children's toys and mattresses that catch fire.

Germany appears to have far higher shop floor involvement in industry. The workers normally know the best way of doing a job and if they are listened too will reduce costs and time. In the UK they bring in management consultants who talk to the workers and then present the ideas to management...

You are correct that machining has an environmental cost. But is it significant for this back of an envelope calculation. Good joinery isn't cheap, cheap joinery isn't good. Does a skillful joiner, who will be paid more, use more materials than a bad one. The cost of transporting a £300...
