Fossil Fuels

Can someone explain How 7,000,000 tonnes of wood pellets get to Drax power station and not using fossil fuels. ...

"" They don't at the moment because most ships and land transport systems are diesel""

Do you realy know about what you post.

Eric

Read this article on BBC News a few months ago and found it hard to understand the reason for it.

Fossil Fuels

Can someone explain How 7,000,000 tonnes of wood pellets get to Drax power station and not using fossil fuels. The trees cut down in America and to be pelletised no doubt they used products from the Oil Industry which suprise suprise is a Fossil Fuel. The transport accross America then the Atlantic. Put on rail to Sheffield all Fossil Free?? All paid for by the consumers. All done with No damage to the environment where the trees are harvested from complete with a regeneration program in place maybe???

Hi Simon

One method used when assembling 'Taper Lock Bushes' is insert a 'Fox Wedge' or a flat blade screwdriver in the slot of the bush to open up the diameter slightly.

Then fit it into the pulley-flywheel with the retaining screws done up finger tight only to keep it secured the it will slide easily on the lightly greased shaft. NO grease on the tapers or retaining screws.

Hi Robert please sit down first

Always alifelong intrest in Velocette I googled for KSS the bike in the photo

Hi A Velocette fan from way back I spotted this hybrid one parked. The owner had fitted an overbored to 499cc KSS motor into a MSS frame.

Running a gas flame heater in a small workshop producing carbon monoxide is not good for your health or for that matter your survival.

It was not broke I did not need to fix it. Now I wanted to break it so now we all need to work to fix it.

Good luck trying to put 1/2 inch U.N.C. nut on whitworth and vice versa

Concrete floor covered with sponge rubber matting with 12 mm painted chip board on top has a slight spring when walking on it. quick clean up with a brush any spills mop up off the painted surface.

I guess the point I made was not explained properly that I use good old fashioned "L" shape Allen Keys to adjust gibs and the Ring end of a ring open end spanner on the lock nut. No excess torsion spring forces required.

Simple solution to the play of an allen key in a socket head screw is to exert pressure toward the screw at a right angle to the rotatation then do up the lock nut.

Cup point set screws with a ball bearing <o> . Tighten all Grub screws remove one dress up the dimple in the jib with an egg beater hand drilll. Repeat on all screws then dismantle and clean up. Reassemble with the ball bearing in first sitting on the jib. Adjust to suit.

Hi Clive

I can now see how a smaller lathe with a boring head fo a ball turner is a bit of shoe horn job.

A round piece of tool steel does a good job and cuts left and right

This is the MEW Boring Bar set up as a Ball Turner. Has turned out a lot of stainless knobs to replace plastic ones.

Eric

Hi Jim

Boring Bar head on a bushed shaft mounted horizontaly on the toolpost with a round nose high speed tool steel with the cutting edge on the vertical centre line will work fine and will cut on the right or left swing.

Use the tool upside down with the flat side facing downwards.

A 400 mm lever on the piviot shaft will give good control and finish with minimum effort.

Eric

Poly Vee Belt 2 Ribs "j" 4.64 mm wide will do the job.

Pulleys in aluminium are easy to fabricate with a high speed steel tool ground to 40 degrees.

Eric

Hi

If you overtighten the adjustment the punch will not cock it properly and will not work.

Eric

Disconnect the leads from the motor and connect a 230 volt Light bulb to the control box motor leads.

Turn the speed control to the lowest speed then power up the control and turn up the speed control the light should get brighter. The control is O.K. if the light gets bright.

A 12 volt car battery will test the motor to run it allbeit slowly. If their is a short circuit in the motor the leads will get very hot super quick. Best done outside and away from flamables.

Eric

When someone posts a question on MEW and I answer with how something actualy works and go into some details to explain it.

Then they repost my explanation in full then tell me it does not work like that at all. That they have a Theory of the way that they Assume it works is correct and is the only way to solve the problem.

The ones who drift off to post on something that maybe remote and possibly connected the subject being discussed on the forum

Hi

Lets put all contradicting assumptions to one side they are the basis for misunderstanding and cause for many major disasters.

The plan in mind is to deal in facts only and avert such happenings.

The 5 mm 10 mm backlash that you demonstrate in the video is explained in my posting 1) to 5) Which is easily moved by light finger pressure this also allows a cutter that has not had the excessive lead backed off to drag the head down when machining Cast Iron, Bronze, or Brass.

The Worm Wheel does actually turn slightly as the clearances are taken up in this order 1) 5) 4) 3) 2) with a single start worm it is normaly self sustaining.

Perhaps the answer "using gravity to advantge" would be to add a 5kg-8kg weight to the cutting head to take out all the backlash when the head is being lowered and remove the weight when you need to raise the head.
