Hi Coal Fired fans,
I was so pleased with my coal fired D.J.B. Edrig that I completed about two years ago I began to have a think about putting together a new kit. I didnt want another Edrig nor did I want a Ragleth, so what else was on offer from Accucraft to fit the bill?
A Mortimer came to mind but what about the coal bunker on the back of the cab. It would have to be removable to clean out the boiler tubes. Would the firebox door drop down to place coal in the hole and the side water tanks would have to be cut down to fit. What were or are going to be the pitfalls?
Well I have made a start. The attached photos speak a thousand words.
Problems that I have had so far. Well not that many, fingers crossed as I am still in the build.
First off the chassis build is as straight forward as the Edrig so no problems there. Most of the puzzling comes from fitting and adapting the body to fit.
As far as the body of the Mortimer goes I found it easier to keep the saddle tank and the cab fixed together as one when trying the trial runs fitting it over the boiler. The first thing I noticed was the saddle tank is a tight but not impossible fit over the boiler with the boiler wrap supplied by D.J.B. in place. Without the boiler wrap its a far better fit and the safety valve bonnet fits better as well. I may discard this from the build. With the saddle tank over the boiler in a position where the original tank filler cap goes to line up with the blind boiler bush fixing and the cab fixing holes lined up with the holes in the running plate, the front of the saddle tank is just short of the rear of the smoke box. Not a lot but I think I may get away with it! I had to make a new fitting to allow the original saddle tank to screw into the boiler bush. The removal of the bunker from the cab was easier than I thought. I used a mini disc cutter to cut through the metal on the bottom of the cab on both sides. Then using slight wiggling motions I lifted the back bunker up and down till the solder joint at the top of the cab came adrift. Now this solder joint is not very good and it comes apart, or at least it did for me without breaking off the head of the rivet on the outside of the cab. So far so good. The back sheet of a coal fired Edrig is almost touching the cab sheet and so it is on the Mortimer so it had to be moved back a little. Also a cut out in the back sheet of the coal bunker was needed to drop down the firebox door enough to get coal into the firebox via a cranked shovel. This cut out again was done using a mini disc cutter. The bunker will be tidied up towards the end of the build. The coal bunker/cab rear has to be fixed to the footplate and cab roof. The bottom fixings are rivets soldered into position and fix into the drilled holes in the footplate floor. Not a lot of room as can be seen but it is secure. The top of the rear bunker/cab will be held in place by a strong mini magnet fixed in turn to a small plate of steel on the cab top rail and another piece of right angled steel soldered to the rear under side of the cab roof. The roof will be in place when the rear bunker/cab is offered up to the back of the loco. Well thats the plan. The side water tanks are going to be about 50 percent smaller than those in an Edrig. I have cut them down ready to solder but still have them to locate etc.]

She looks very well:clap::clap::clap: Will a 50% loss of water capacity inhibit her operational use in any way ?

Hi Garry,
Well at the moment I don't think so. If I start with two thirds of a boiler full and the side tanks full it should be OK till the first re coaling. If things look a little low on water I can use the garden pump to re fill the boiler via the enots valve. Won't really know till its fired up snd running,
John.

Not that I have any underlying motive John, but I'm sure a Jackson's Miniatures 'Superior' water top up bottle would be a useful accessory, if you don't already have one. :D

Hi Steve,
The comment put a really big smile on my face this damp and miserable Sheringham
morning. To wet to go mackerel fishing even.

Dan has received no reward for his unsolicited recommendation. That's right, isn't it Dan?
(The cheque will be in the post this afternoon). :D

Re:Coal Fired D.J.B. Accucraft Mortimer

More photos and info as I continue with the build. The next job is to fit the side water tanks. It looks like they are 1mm to wide to go into the Accucraft body! Will have to see how it goes this weekend.
John.

Re:Coal Fired D.J.B. Accucraft Mortimer

Well the water tanks are in. Sods law said that they were going to be 2 mm to wide to fit into the Mortimers side tank hole. I got around this by soldering the pieces of brass that make up one side of the tank to the inside of the return tab of the narrow end of the tank, if you follow. This makes the water tank narrower and a snug fit in Mortimers side tanks. The other little problem is the brass tubes for the water balance pipe. I have located them in such a position that the inside sheets of the Mortimer side tanks need not be cut. The brass pipes exit the water tanks right adjacent to the rear boiler support though. As I wanted the loco body to be a drop fit over the boiler the brass tubes also had to cut back to fit over the boiler. There is enough length of silicone tubing supplied by D.J.B. to form a gentle curve around the front of the boiler support to connect the two pipes up and avoid and kinking to allow the water to flow between the two tanks.
The awkward bit seems to be over, just got to get on with the general build now.
John.

Its been a while since I stopped work on the Mortimer D.J.B. coal fired boiler conversion. Two reasons really. The first was inclement weather and finding somewhere to spray the component parts. The second was a Roundhouse Fowler coal fired conversion I bought from Simon at Anything narrow gauge at Bressingham last summer. I will post photos of this loco in a short while.
There were a few head scratching moments during its conversion. Anyone wishing to convert a Mortimer can contact me for any advise they may need. Not got round to firing it up yet but I have no reason to believe it wont be as good as the Edrig.
Regards. John.

That´s beautiful, that it is. Almost makes me want to install ventilation on the indoor K&NWLR for coal-firing - a Swiss friend down the road has done it for his cellar-based G1 line, and it must work as he´s still married. :eek:
