Thread: Storing Machinery In Damp Conditions - Advice Please
23/10/2018 14:53:05

+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

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.

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?

Have you seen the carbs made by Jan Ridders? They are glass cylinders or glass end plates.

As Michael has indicated, you do need a pressure regulated output.

As a novice to this type of work might I suggest getting some basic material to practice the machining work and technique before starting on the final piece.

Came across someone who fitted an Ardunio system instead if this is feasible.
