Thread: Self starting small steam engines
27/07/2018 08:12:05

This is the engine. How would your cam/spring idea work Bazyle?

Duncan and Bazyle......would you kindly expand on what you have said above. I will post a picture of the engine in the morning which might assist on the cam/spring and sprag clutch ideas.

Mick

Edit:- I was tinkering with the idea of a solenoid operated spring mounted rod which would "flick" the flywheel if necessary. Unnecessary complication agai I suppose.

Is there any angle other than 90 or 180 which although not guaranteed, might provide most likelihood of self starting?

The engine has a rotary valve by the way.

I recently purchased a small marine engine with 2 x 5/8" single acting pistons with 11/16" stroke. The cranks are at 180 degrees so that when one piston is at tdc the other is at bdc. The motor turns over quite sweetly with low pressure air. If the air is turned off then on again it will sometimes self start......probably about 25% of the time, but as the engine is destined for a boat it will be mighty inconvenient if the engine stalls midstream in the river.

Other than remaking the crankshaft and setting the cranks at say 90 degrees are there any other simple wheezes to promote self starting.

Thread: vertical boiler thread
12/07/2018 15:25:39

Thanks Jason. I did mention those woods and trees. Just interested in whether the chappie got it fixed.

No more than a couple of days ago there was a thread about a leak on a water tube on a vertical boiler. Has the thread been removed because I now cannot find it? Mind you, I am well known for not seeing the wood for the trees.

Could you repost the photo Keith?

Thread: EN15 Phosphor bronze?
07/07/2018 21:02:06

This stuff is quite definitely not steel. I suppose the mark might be a local code.

Mick

Sorry Hopper.... and well spotted......it is EN15.

Mick

Does anyone recognise the code EN15 engraved onto a rod of what I think is phosphor bronze?

Thread: Battery Packs for Remote Control
29/06/2018 07:36:28

Thank you for the information and recommendations gents. I am currently perusing their offerings. I didn't realise there was such a range of stuff out there.

I have been gifted an unused MacGregor Digimac VI remote control set dating from the 60s or 70s. The battery packs , 500mA NiCads in 3 packs of 4 are defunct and require replacement. I have tested the Digimac and it functions well on temporary 1.5V dry cells. My first thoughts are to replace the batteries with NiMH cells which will have a greater output and presumably will work for longer between charges.

My questions are, where shall I source the new batteries from? There are loads on EBay but they vary wildly in price although they all look the same. Anyone had any experience in buying them?

Secondly, the Digimac charger has no markings and is the type that cuts out when full charge is reached. Will this charger handle NiMH batteries say between 900mA and 2000mA?

Any advice appreciated.

Mick

Edit. It is for use on a steam powered boat

Thread: sealed glass window failure
20/05/2018 21:07:04

Thanks all for the advice.

Mick

I am lucky enough to have sealed glass windows in my workshop but both have failed over the winter. I have heard of a means bringing them back by drilling a hole and sucking out the air and resealing. Anyone tried it?

Thread: WM14 Mill Drill lubrication
03/05/2018 17:46:08

May I ask how other owners of Warco WM14 Mill Drills lubricate the topslide slideways? I can't work out how to do it without stripping it down which is a bit drastic.

Ordered metal 19th April and it arrived this morning 21st April. First class service as far as I am concerned.

Thread: Locomotive scales
06/04/2018 12:24:01

The superb Garden Rail show is on at Peterborough Arena tomorrow. It is mainly 16mm but also a fair bit of Gauge 1 (10mm or 1/32). A good place to go to appreciate the distinctions between scale and gauge as they all run on 45mm gauge track.

Actually no, I have that wrong! G gauge is smaller than 16mm gauge according to my book by Peter Jones.

 

I think that you may have misread something Chris. Garden (G) Scale is usually 16mm (to the foot). The track on which it runs may be either 32mm (gauge) or 45mm (gauge). "Scale" and "Gauge" are not interchangeable terms.

I usually build Gauge 1 stuff which can be either 10mm to the foot scale or 1/32 scale. Either will normally be built to run on 45mm gauge track.

It follows that Gauge 1 locos @ 10mm scale will also run on the same track as Garden scale 16mm locos.

I hope that this has not muddied the waters further.

Thread: Burglar alarm
16/03/2018 18:34:08
Posted by Mike on 16/03/2018 17:49:48:

When I first started reading ME, I think some time back in the 1960s, there was a letter from a chap who got totally fed up with break-ins at his workshop, which was in a rural location. His answer was to buy a redundant electric factory hooter, and wire it to an alarm system so that most of the sound was directed inside the building. I seem to remember that the first low-life to break in ran straight through a glass window in his hurry to get out, and the second was led out, a gibbering wreck. After that, word got around and the break-ins ceased. Pity you couldn't get away with such a trick these days!
