Coal Firing Accessories.
« on: April 09, 2013, 05:20:39 PM »

Hi All.

John Smith, another member, and I have just purchased another coal -fired locomotive. We would be most interested to hear if there are suppliers who could supply suitable blowers, shovels, flue-cleaners etc etc for Gauge Three coal fired locos.

Thanks.
Robert. 492.

There are several suppliers that specialise in this area Robert

If you go to Polly Engineering at: http://www.pollymodelengineering.co.uk/index.asp you can download the Bruce Engineering's catalogue, it's in PDF form (the two company's merged a few years ago I believe) and you should find most of what you will need.

Also look at Blackgates Engineering at:  http://www.blackgates.co.uk/

I have used both of the above companies in the past.

Regards,

IanT

Aster Hobbies does a very nice battery powered chimney top blower. Contact Andrew Pullen at asteruk(at)gmail.com or see website: http://www.asterhobbies.co.uk

Recently I have been experimenting with chimney mounted blowers.
I had a 6V motor driven one for my old 3 1/2 inch gauge Tich. It hardly pulls a draft.
So I have decided not to re-incarnate this one to steam raising in Gauge 3.

Am amazed at the prices asked for purpose built blowers so decided I would re-design my own.

Using bits of old scrap central heating copper tube , a Tee with compression joints, a 90 degree elbow compression joint. The piece de resistance though is the blower. From a camping & outdoor store in town I bought a camp air bed inflater 12 volt operated with a cigarette lighter plug. Cost of this was only £5.99.

So cut off the lighter plug, stripped the wire back & fitted car type spade terminal clips to go straight onto a 12Volt SLA battery. The inflater even has it's own on board on/off switch.

A piece of copper tube was cut & adapted to chimney internal diameter then fitted to the elbow. The elbow was adapted using 3 inch of copper tube to the Tee piece. The vertical pipe was fitted to the Tee & directly opposite another tube was fitted & adapted to the air bed inflater. So the pump was in line with the vertically copper piped chimney. The loco chimney effectively being offset to the side.

This blower will suck a draught up the chimney into the air stream vertically projecting from the air bed inflater.
The hot exhaust from the loco is in copper pipe. The ambient air through the plastic pump is pushed into the copper pipe. The proof of the pudding is if it works. So the fan & motor are quite remote from the hot gases & smoke.

If it does not perform then I have wasted less than £10

I understand Dave has been a bit poorly recently Ian and he may not be logging on here at the moment.

If you are lurking Dave - then I'm sure everyone on the Forum sends their best wishes.

The best and cheapest blower for coal fired locos can be obtained from Steam Fittings, here is the link: http://www.steamfittings.co.uk/asp/d-no.asp?ProductID=189&Process=1

The price has gone up a bit since I bought mine; they used to be £10.  The motors are excellent and they run on 24 volts which you might need to raise steam depending on the size of tubes and firebox layout, some boilers need a strong draught.  There is a bot of engineering to do making a plate to go on the bottom plus something to go into the chimney; the ones he supplies are too large for 2.5" gauge locos.  I made a brass plate with a machines circular tube type of thing and I have different coned shaped pieces that fit into the tube, you need different cones for various chimney sizes.  I can recommend the product; it has worked faultlessly for me for quite a few years now.

I have something very similar Phil - however if I was starting out again, I might try a slightly different design. With the unit sat directly over the chimney, the hot exhaust warms mine up pretty quickly (too hot to touch) and I'm sure my unit wasn't originally made to run that hot. Also (even with a mid-sized sealed lead acid battery) it seems to run the battery down pretty quick (e.g. within one running session).

I've seen smaller units using cheap D/C motors (that are off-set to one side) and that therefore don't get so hot and that also seem to run off smaller batteries all day long - not sure if they were 'commercial' units or not though.

I might try to run mine as a 'blower' (with a side flue) to get over the heat problem but it won't solve the battery issue.

Yours may be a different animal entirely of course!   :-)

Hi Ian

I think mine must be a different animal as you say.  What Steam Fittings are selling is ex-MOD 24V blower motors out of some 1950s aircraft, they are new old stock.  Being MOD/RAF they are massively over specified and really heavy duty.  I think they are a bargain even at the £20 now asked.  I run mine off 2 x 12 volt 7 amp hour gel cells wired to give 24 volts.  I also have a cheap Chinese variable voltage thingy (solid state from eBay) and that lets me vary the speed of the blower which is very useful.  I would not have thought an Aster unit or similar would be man enough for a 2.5" gauge loco, I know my coal fired engines need plenty of draught to get them going, so does one of my bigger meths-fired ones.
