Thread: 2020 Had my full size flash steam engine running

Wonderful! Is the poppet valve pressure balanced in any way, or does it just open against HP steam?

Afraid not I played about with them in my early days with the model but have high rpm to contend with.

Discussing this with my steam rocket drag motorcycle friend when his poppet valves went wrong against tons of water pressure.

We came up with a very simple nearly balanced poppet valves they would probably be ok at slow speed openings.

He decided on a butterfly type valve instead from America that their water, steam rocket people use successfully.

The successfully Canyon jump machine jets were similar to his rocket motorcycle power unit.

Not sure if my link worked on my slow speed test runs so will try this.

Another test running on compressed air.


05/01/2020 15:56:32

Had my full size flash steam engine running yesterday on compressed air unfortunately have not got too much pressure and quantity for high rpm so just a pop, pop at low rpm.

Had to retard inlet poppet valve and use compression release valve to enable it to run with my limited compressor also added temporally extra mass to crankshaft for this test a lathe chuck.

Would run on about 90psi with this setup but need a lot more pressure to run on the proper valve settings..

I bought a S7 a few years ago with various chucks.

Most were a very good but tight fit.

Have you checked a bit of swarf or damaged thread is not causing binding.

Sometimes swarf can become embedded in the metal.

At long last am at a stage to test run on compressed air.
Unfortunately my compressor does not have capacity and high enough pressure.
Going on my experience with flash steamers will need at a least 150psi and a lot of air my petrol head friend at work has a screw compressor and 150psi so in the New Year will see what happens.
At 120psi it’s so near continually running and a sharp exhaust noise on air.
With high pressure superheated steam could be an interesting noise.
It has a variable compression release valve to ease starting but flattens my air supply.
Will finish welding the exhaust manifold today amongst other jobs.
All the best to you all for 2020.

Have run it on 12v and seems to be ok will be seeing a club member who is into electrics and Vignoles

Possibly a tacho generator ? Colour & painted on markings look like those seen on military equipment, so maybe a TG from an engine to drive a tachometer remotely on an instrument panel. If you have a DC meter, try connecting to the terminals & spin the shaft to see if it generates a small voltage - the voltage will be proportional to the speed.

I've used similar looking devices for speed feedback on machine tool spindle motors - usually 60v/1000rpm in that application. No real current available, though - the windings are optimised to provide an accurate voltage with low ripple.

              Just rotated it at about 500rpm on the lathe and got 1.47v.

I got 2 of these at a car boot years ago would like to know what they are.

The manufacturer was taken over by AVO is it part of some test equipment or motor, generator.

One is brand new in a sealed package.

As I am downsizing my workshop there are bits and pieces for sale on the ME for sale column

Just had a reply for two items one was free to collect.

Warning bells rang as wanted a price for the free item.

My advert said it all so checked the Email given on the web.

According to the Web it's down as a scammer.

Will see what there reply is if dodgy will reveal the Email.

Thread: 1.1kw motor iffy
24/11/2019 00:17:39

Apart from installing a simple clutch probably related to a belt tensioner to reduce starts the problem will be with the metric screw cutting.

Have checked with a single phase motor supplier

N.B.: it is recommended that single phase motors are not stop/started more than 15 times within a 1 hour .

It's also in Tuba Cain model engineer handbook.

Afraid have exceeded that at times my early Warco 600 is certainly my workhorse for much of my machining.

Have a Myford for more delicate work but is rarely used now as on a larger project.

Hi Windy,

There are various qualities of capacitor out there, it might be better to buy one based on the specs from somewhere like RS. Does the spec printed on the cap body match the old one?

The start Cap takes a beating, higher volts and life hours are better, that said I would expect a new cap to last longer than a month.

All the numbers are the same as the original duff one if this replacement blows in a short time will try a better quality capacitor

23/11/2019 15:56:33

A while ago I replaced the start capacitor on my single phase Warco 600 lathe .

The starting was ok but seemed very aggressive I don't seem to remember it was like that when first purchased as a used machine..

Start capacitor has gone again think will have to arrange a clutch to ease things but wonder is there any product that can protect the start capacitor.

Doing metric screw cutting there is a lot of turn, stop and reverse going on.

I have a spare start capacitor to fit the motor it does start in the lower speeds and am reducing belt tension with the pulley speed lever at the moment when starting.

Any suggestions before I replace the start capacitor.

Thread: A unlucky accident
21/11/2019 17:58:57

So sad when accidents happen and the after effects are so serious

I have had an accident when in my 70's had got unsteady for a while(after effects of medical treatment) was in the workshop at 10-30pm.

Fell and shoulder dislocated laid on the floor awkwardly what a job getting help.

Now have phones everywhere I was lucky just the shoulder injured and bruises

A and E came it was a wakeup call you think your ok at home.

Thread: Motorcycle General Discussion
18/11/2019 22:45:34

Has been very interesting following Bloodhound testing some of the issues found was a vibration sensor set too fine when going over a track on the desert that shut the engine down,

Braking parachute , air brakes and normal brakes being checked and sometimes modified.

A hot wire sensor system shutting the turbine down when engine and chassis got too hot.

Part of the rear wheel outrigger streamlining coming adrift.

Also finding various stability things at speed.

Being tested in a very hot climate raised issues with control systems which they did not get in the cooler UK.

It seems they were very minor problems which the team overcome.

Just waiting for the official record attempts with the rocket assist engaged a fantastic bit of engineering.

If any speed enthusiast is following Bloodhounds testing here is Andy Green comments on his 628mph terminal speed run.

Hopefully next year will be the record attempt with the additional rocket assist attached.


Thread: Miitutoyo caliper error
06/11/2019 23:52:24

Years ago at a car boot I bought a faulty Mitutoyo caliper for a couple of quid and found the battery contact was not a very good contact with the battery.

Sorted that out and its still going after 25 years.

Thread: Cutting stainless steel rod. Bandsaw or chopsaw?
04/11/2019 09:12:28

I have one of Aldi bandsaw and pleased with it for the price the vice is the weak point but will eventually be modified.

Have cut various materials with it and bought a set of three milwaukee bandsaw spares cost £26.45 .

A coolant system would be handy for it.

Before had to cut some 2inch en24t and used a 4inch angle grinder with a metal cutting disc the bar was 6foot and was on axle stands.

Noise was the downside so neighbours might not be happy if used regularly. .
