I built Malcoms level control and his attenuator valve for a 24 hour running competition in the late 1990s at that time we both were building Vic Smeeds River Queen although I designed my own V twin wobbler and a center flue boiler.Malcolm designed the MB22 and it is a far better runner than my...

I think Malcoms design had an update or a mod just cannot remember If you look on Paddleducks Malcolm replied to a problem a member had building the unit I made his unit and it worked reliably .This was all pre interwebby we used to have a correspondence circle via snailmail Malcolms MB22 engine...

Use a Schmit trigger and a 555 chip to stop bounce A dual packaged timer chip 556? could be configured to drive an rc servo to operate a bypass valve Malcolm Beak had a design published in Model Boats magazine. He is approachable gentleman and can be found on Paddleducks forum or Modelboat...

My Father and Grandfather were cabinet makers and I still use some of there tools to this day.Some are stamped with there initials always a reminder, and I can often hear the old bugger in my ear when I use his favourite old Bailey hand plane although its never as sharp as he had it My father...

Funny how we connect to tools from our past I have a metal piercing saw that belonged to a true gentleman from the days when I was a snotty nosed apprentice. Every time I use it, it always brings back very happy memories of its long gone owner. I often catch myself using some of his sayings when...

Plan for the future but most importantly live for today cheers

A dog is a must it gives the day a bit of purpose or else I would be playing in the shop all day Wont be long Jon dont worry it soon passes My two scoundrels

Iv had a Vertex 4inch for about 8 years and its been a decent enough table for model making and gear cutting . It is never going to be toolroom quality but for the money a great buy and suits my needs

By then I think I will be looking at the daises from the hairy end

Only 7 under my belt Worked in a job I hated with people I disliked now I can and do what I like well with swmbo permission Wish people wouldna keep mentioning that dirty four lettered word cheers

Hi, I dont have any wiring diagrams so cannot comment. I used to simply switch the motor off in the set up ,This allowed the rest of the machine to function but its a long time past I had a look in the workshop to see if I had kept my old notebook for the HAAS machine but no luck plenty for...

Good luck with youre Moriya its a nice build and was the first Stirling engine I built Just had my half sized version running today for the first time. Its based on Moriya and a few mods as some parts would not scale Just starting on the fan and its guard best wishes frazer

I bought a 1inch Mitutoyo in my early 20s and still using it 40+ years later Bought a chinese 1inch internal mike 3 years ago and the numerals have rubbed off the dial hmmm

Before you send the motor to the repair shop. Check the brush holders with youre meter as Iv seen the insulator break down on similar motors From memory I think the encoder is an etched glass disc so be careful Nice to see its on the mend

That is good news and at least it looks like youre chasing it down Those motors do take a lot of cleaning and after a good road run Im not surprised I would do as you say and split the motor from its cable and test to see if its motor or wiring Also if you are blowing the motor out with...

Sorry Iv never built an Alpha You could ask on the Stirling engine forum cheers

I think the problem could be carbon dust as we used to get problems when the machines were moved around a toolroom . They take a bit of cleaning with an air gun and a shop vac. The test meter will show it up I would go for the shuttle motor first and please check its cables if it has the flexy...

I use ptfe packing in the pistons of larger engines as in 2 to 5inch bore my last 2 inch bore engine will run on one 1/4 dia wick meths fired as can be seen on the wee video I know others have used the old style of graphited rope for packing

Ten thou is far too large more like 0.0001 that is for the power piston The displacer can be around 40thou clearance The hot cap is better made from stainless steel and machined to a wall thickness of about 20 thou then machine a section near its mounting to about 15 to 10 thou this makes a...

Yes but remember the fault maybe in the cabling and not the motor You can also disconnect the supply to the motors on the I/O board this way you may not get the over temp alarm as that circuit will still be intact From memory #7 then e/stop the machine takes you into set up. The up down or left...
