Homemade Tools - Snow Rake

I put this together from scrap 2 x 1 and 3/8" (10mm) plywood. I used some pieces of waste wire from electric cable (string would be just as good) as ties to stop the board pulling off the end of the 2 x 1.

New Science Q&A Article for Children

Just published a new science guide for children.

"Top 100 Interesting Science Questions for Kids" covers space, nature, technology, engineering, elementary math, chemistry, physics and biology.

AA to C and D Battery Converters

These are useful little gadgets if you don't have any C or D cells to hand. AA cells are readily available in cheap packs from pound/dollar/euro shops and are probably also optimised to have a higher energy density.

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.

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!
