Snow Shovels by Briggs & Stratton

Think I'd prefer shovelling by hand to warm up, but these snow shovels by Briggs & Stratton could be useful!

Lidl Tools from the Centre Aisle - Air Wedges

Picked up this set of air wedges in Lidl . They're like a mini version of what firemen use. Handy for lifting and positioning stuff and pushing things apart.

Valves for Shutting Off Water in the Home

Just a reminder folks to identify where all your gate valves are for shutting off water in an emergency. Tie a label around them or write the function on the wall behind with a thick marker. Valves can and do seize, so it's good to exercise them at least once a year. You don't want to be running around like a headless chicken when there's a water leak.

Cutting Down the Overgrown Sycamore

My shepherd's hook for pulling down the overgrown sycamore in the back garden. The plan was to cut low and reach high with the 20 foot hook to get leverage, without having to climb up to tie ropes.

The hook was made from a 6m length of 12mm rebar, with a loop at one end for hooking around limbs and a smaller loop at the other end for attaching a rope. Unlike a rope, the hook was rigid and could be extended high up into the crown, without having to do any climbing.

One 8" bough down, about 8 more to go. This one managed to land on a sheet of steel that sliced into it.

I decided to make a rope saw for cutting through some of the limbs that were nearly vertical. It would have been dangerous to cut these with a chainsaw while I was up the tree. Using a rope saw was slow and hard work but really safe because limbs could be cut remotely and pulled down using a long rope and my sheperd's hook. The saw was made from an old chain saw chain. I cut one of the links with an angle grinder and opened it out, then attached the ropes to rings passed through link holes in the ends of the chain.

Finally finished cutting!

Lots of logs to cut up.

I chipped all the branches. They can be used as fuel on a stove or as a mulch in the garden for suppressing weeds.

By winter last year after a warm summer, the tree had put on 6 feet of new growth. Looks as if I'll have to do more lopping this year!

Sharp Vintage Calculators

My favourite calculator, the Sharp EL506. Really simple to use and no fancy "natural entry" nonsense that slows everything down in modern versions, with lots of extra keypresses required to do simple calculations. Cost me £5 in '84 when I started college. Batteries then lasted over 20 years.

"Talking Tools"

Just wanted to let you know about my new Facebook group "Talking Tools".
It's a platform for pros and newbies to talk about tools, share reviews and tips. Novices can ask questions and get help from more experienced members. Manufacturers can also show off their new products.

Lawn Mower Won't Start? - Top 10 Small Engine Troubleshooting Tips

1. Use fresh petrol (gasoline). Old petrol can cause difficult starting. Make sure there is enough fuel in the tank and check the vent in the tank cap isn'tclogged
2.  The spark lead should be firmly attached to the plug, and the plug tightly screwed into the engine block. Try replacing the plug with a new one if the engine won't start
3. Most modern mowers have a control handle which needs to be pushed forwards/upwards and held in place to keep the engine running. Make sure this control is mower is held fully against the mower handle while starting.
4. If a manual choke is fitted, turn it on. Don't turn on the choke if the engine has been running in the last 10 minutes
5. If the engine has a primer bulb, press it about 5 times. If the mower runs out of petrol during cutting, it will need to be primed again
6. Check the air filter isn't dirty. Wash and dry foam type air filters in warm,soapy water. A paper filter can be blown out with an air compressor, but will eventually need to be replaced
7. Check the cable connecting the "dead man's handle" (the control which keeps the engine running when held in place) to the engine is not damaged or snapped
8. The carburettor should be tightly screwed or bolted to the engine
9. Make sure there isn't any water collected at the bottom of the petrol tank. If there is, drain the tank and use a piece of stick or long screwdriver with a piece of rag tied on (with a twisty tie) to soak up water
10. If the starter cord is hard to pull, check the underside of the deck and remove any clumps of grass which may be jamming the blade. Disconnect the spark lead before attempting to move the blade to remove clippings!

How Can the Pressure be Increased in a Shower?

If the shower is fed from a hot water tank, a cold water tank provides the pressure head to force out the hot water from the tank. This is usually in the loft to maximize the head so if it is located there, you are not going to be able to rise it any higher.
Cold water power showers are fed from the incoming mains cold water supply and the water is heated by a high powered electric element.
Shower heads incorporate a restrictor/aerator to reduce flow and water wastage. The Federal Energy Policy Act of 1992 made it a requirement that these were added to shower heads to reduce flow to about 2 gallons per minute, so removing this would increase the flow rate. Also it is possible to buy a shower head designed for a lower flow rate. This increases pressure but the flow rate will be less.
You can buy a booster pump which effectively works like a power washer and increases the pressure while keeping the flow rate constant.

How Can Hand or Garden Tools be De-Rusted?

Remove excess rust with steel (wire) wool soaked in lemon juice or vinegar which are mild acids. Rinse the tools and allow them to dry. You could soak the tools for a period to remove excess rust.
Another alternative which definitely works is phosphoric acid. This is often a constituent of rust removing chemicals and can also be bought in gallon containers from companies which supply cleaning chemicals. It is a powerful acid and can also be used for removing limescale from surfaces. Usually it is diluted with water before use. The objects being cleaned are submerged in the solution and should only be left in the acid for the bare minimum of time to dissolve the rust, otherwise the acid will start to dissolve the underlying metal! I have cleaned an old vice pillar drill vice belonging to my grandfather which developed a thick layer of rust after being exposed to dampness in a shed for over thirty years and the acid completely removed the rust.
Once you remove the rust, rub some oil into them and wipe off any excess. This will help to prevent future corrosion.
Sand can also be used as an abrasive for removing rust from tools.
If you wipe tools with light oil after use, it helps to prevent condensation and subsequent corrosion. Guns and tools were traditionally given (and probably still are) a coating of oil after manufacture and before packing to protect them from dampness and rust.

What Does the Voltage Rating of a Fuse Mean?

The current rating of a fuse specifies the current which the fuse will carry without blowing. Once the current exceeds this value, the fuse will eventually blow. The characteristic of a fuse is such that if the current in a circuit is moderately higher than the fuse rating due to an overload, the fuse will take some time to blow, possibly seconds, minutes or tens of minutes, depending on the magnitude of the overload. If the current is a lot higher e.g. in the case of a short circuit, the fuse will blow in a few tens of milliseconds. While a low voltage or high voltage fuse will blow when the current exceeds the current rating, the current flow in a mains powered circuit can be extremely high (possibly thousands of amps) in a short circuit scenario because the current is coming from a large transformer outside the home. The breaking capacity of a fuse is specified in joules or kiloamps and a mains fuse could have a rating of 10000 amps or more. This is the maximum current the fuse can carry without rupturing. Usually fuses for mains equipment or distribution circuits have a ceramic body to withstand the heat and shock when the fuse blows. The fuse is also filled with quartz sand to absorb the heat and shock and quench the arc when the fuse blows. A glass fuse could simply rupture and possibly cause a fire if it carried such a heavy current. Glass/low voltage fuses may be used on the secondary side of the transformer in the power supply of equipment because the current output of the transformer in a short circuit situation is limited.
