And a complete chapter on making your own fireworks.

Don’t see that in modern books

Did you notice that the page of ingredients for the fireworks was out of focus or was it just me?

Snip

Thanks I did not realise that pattern went that large . Wichard are notoriously expensive but I will find out the cost

Yes, I was surprised too, then again I dread to think of the load on some sheets carrying big sails in a blow.

Thread: Coil winding

I think that is the difference between winding a coil and winding a spring.

Thread: Lead Bearing Solder is Banned

Thanks for that. I was interested to see that you receive visits from the powers that be.

I used to work with refrigerants, before retirement, and those in the trade were annoyed, and still are, at the complete lack of anyone from the Environment agencies showing any interest in getting people/firms complying with current legislation.

Anyway, rant over.

It could also be the operating coil beginning to weaken, depending on age of course.

Second thoughts - plan to build your own here....

It seems that you have been given some options but not knowing where 'local' is made it hard to answer for me, sorry.

+1 for ACF-50, used to use on my motorcycle and last winter used it on my mini-lathe sat in the shed in the garden.

Also gave the hand tools a wipe over with it.

Thread: which compressor
23/10/2018 00:09:23

Are automotive air con compressors compressing gas or liquid?

The usual advice is to run the air con on the car for about 5 minutes each week to keep the seals lubricated. That suggests liquid rather than gas. Or maybe the refrigerant is below its critical temperature, and when compressed it changes to liquid, and that is what lubricates the seals.

Anyone to enlighten us?

Howard

All refrigerant comoressors, electric or mechanical pump vapour, if they pump liquid they very quickly destroy tgeir valves or con-rods.

It is the oil mist mixing with the refrigerant that provides the lubrication to the seals etc.

Thread: Pumping water up a hill

Not sure if this is the best option but have you looked into 'ram pumps'. These use the water itself to perform the pumping action.

This **LINK** site is commercial but will give you an idea of what can be acheived.

Sorry, can't see it from here so wouldn't like to guess.

Use a round file across the hole.

Thread: which compressor

How do automotive air-con compressors compare with fridge units? Anyone know? Obviously need a drive, for starters.

Price wise a lot more expensive.

A fridge compressor with starter electrics can be simply plugged into the mains to run.

An auto compressor needs a drive motor, motor pulley, drive belt, 12 volt dc supply to operate the drive clutch and special connectors for the pipeline. Overall, more effort, more noise, more space and more money.

Thread: Twin Tube HF fluorescent lighting for the workshop

Just for info but we used to check our contactless tachometers by pointing them at a fluorescent tube to check that they were reading correctly. 3000rpm IIRC.

Reduce the amount of tool sticking out from toolpost may help a bit.

Thread: Wyvern cylinder head sealing
02/10/2018 22:03:57

My thoughts as someone who has not made that engine ....

Although you have ground the valves in was the final grinding paste fine enough to leave a smooth surface in the valve seat and on the valve head?

Are the valves fully closed when the rockers are relaxed?

Are the valve springs strong enough to hold the valves closed on the suction stroke?
