Back to the model and I have painted the turbine with undercoat and top coat... I am also going to make a circular perspex drum to surround the top part of the turbine to deflect the air to the blades in a better more efficient manner. Air has only 1/8 the force of water at the same pressure so I can use a smaller compressor ??!! so we shall see if this works ...The perspex block is bolted to the faceplate ready to turn to size.

More work with the Turbine air inlet cover.  the main part is turned up whilst bolted to the faceplate ,..however I need to turn up the other side so I have made another perspex plate to use as a temporary cover to hold the assy stable using a revolving centre to turn the unit safely in position ...  still more final fitting  and also drilling the air intake nozzle orifice ??!!

so a few more pics ...removing some of the material with a 32tpi hacksaw  and fitting the unit with more hand filling to get the correct depth

The air tight cover is now completed and the model reassembled . The inlet hole has been drilled and an air pressure test is imminent !!!

So Back in the wksp and the air compressor is still not operating the turbine ... however I was taking a Microwave cooker apart to remove the two big magnets and found the bowl rotating motor  This is 240 volts and rotates very slowly. I had it connected and found the torque at this slow speed was quite phenomenal. So I am thinking of using this to rotate the model ...I have a large quantity of gears ,sprockets  chain down about 3/16th link size and have made a drive to see how it will work out ??
 more news tomorrow ....

very nice basement for your steam engine and its mechanics!
you are also an expert in machining perspex, so easy to ruin a hole with a drill bit that gets a little too hot...

Hi Zeph,  Thanks and I am just lucky I think as there are different types if perspex and acrylic so I may be just lucky ...also I do drill a lot of my holes with hand tools that are much slower ??

I have now made the motor support bracket and turned and milled from a large piece or perspex...I now need to adjust the chain length and then bolt everything back in place and see what happens ? !!

I like the idea of the chain drive. It reminds me of model engines I've seen in museums, set up to run when visitors  push a button.

Not a valid vimeo URL.      Here is the video of the compressor plant with the electric motorised system working it

So lots more work to finally finish it www.Not a valid vimeo URL So  I cannot seem to attach the video ???   <iframe title="vimeo-player" src="https://player.vimeo.com/video/817096561?h=1336f0c84c" width="640" height="360" frameborder="0"    allowfullscreen></iframe>
