Right, I've been thinking about Britomart a fair bit recently before i go back home for the xmas hols, and i would like to finally get her properly working before the New Year, cause last time i ran her, it was a complete failiure! Below are the listed problems:

The new uprated piston set is still very stiff and needs more running in, but the new regulator is leaking quite a lot, meaning that there isn't enough steam reaching the pistons at solve this. What i think the problem with the reg is that the part where the steam pipe slots into the dead leg lubricator section before the old reg, now reverser, and when i open the reg i hear the fire roar as if it's trying to be blown out, but I've never seen any steam coming from underneath or coming up through the combustion chamber :?

Another problem is that i've seen other mamods and the pistons on them are dripping with oil everywhere, and yet even though i do oil the pistons on mine, i don't think that the dead leg is providing enough oil to the pistons to help run them in :? and also i found that the only time she did run properly, she only liked pure oil in the dead leg oil reservoir, so it meant i had to extract the water out of it every 5 mins!

So yes this mamod is being the most prototypical mamod in exsitance! and the annoying thing is, is that she did run beautifully before i modded her! :x :evil: :evil:


Oh, and one more thing, does anyone thing it's possible to add sandbox levers like on Blanche/Linda etc (or a simular style) to my edrig at all, if the sandboxes were right next to the side tanks on the front running plate at all?

If anyone has any suggestions to fix the steam pipe (soldering?) and the lubrication issue that would be greatly appriciated! :D

After long discussions with the railways engineers, a hard decision has been made, and due to current financial restrictions and resources etc, Britomart is to be pulled out of the loco fleet and to be scrapped if the next test run fails at all.

If it does fail, I'd be willing to take it off your hands. I wont even change the name

Im not bothering to sell her cause shed need a lot of work anyway cause the boiler is shot, (which is the main reason for the scrapping) and also she may come in useful to other plans i have, sorry!

Oh ok. It's just that I know a guy who can fix her up & I need a steam engine anyway so I thought that I could pick up a bargain here. Ah well

well if i did sell her it literally would just be the bare bones of her, no pistons, no buffers etc no boiler (for safety reasons) and a fair few other bits missing so there isn't much point really

Ok, I have just got desperate that's all. I can't afford a new one & I would like one that I could spruce up to make it look the mutts nuts. Besides, a replacement boiler isn't exactly expensive at around £20 is it?

Well, after about 5 steam tests, only on one occasion did she run and also there was a major leak developing from the boiler and also the boiler itself is now shot etc and it's caused me (quite a lot of) hassle really, but you never know, she may just turn into a phoenix.....

:lol: nice guess but no, i'm taking all the good things off her before she goes into storage outside for some natural weathering :D At one point i will also have a "Farewell" steam up for her as well before i do "scrap" her

Noo not the rusty hulk treatment I think she deserves another chance at life even if its with a new owner. (your Railway your choice)

You could make in to a brakevan like the Penrhyn Railway did with Sanford.

Don't scrap britomart, save it :D It looks the 'bee's knees' in that blue :D
What are your 'other' plans?
Thanks

Dont cut it up use it as a learning curve. When I rebuilt my Mamod a few years back after a good 15 years of neglect it didnt want to run at all. It started to get to me and I almost gave up, put it to one side had ago at a few other things and then after a few weeks gave it another go. The new cylinders from ip where far too stiff but after a couple of hours putting oil through the port holes and pumping them for a few hours they soon freed up, then the cylinder port holes, the gasket, frames and reverser block didnt all line up so I put them all in places and ran a drill bit through with my fingers, I also used abit of liquid gasket between the reverser block and the frames so there are no leaks at all from this area. It took me some time but I got there in the end. Even though she has been running for a few years now and could do with a repaint and Im considering a new boiler and fitting one of the gas burners Ive got. It was very nice to see her running at Butterley and the comments from Sir Heydon, Narrow Minded and MDLR that it didnt run like a mamod made me feel very proud.

To be honest I would start with the boiler, after everything youve said on here it sounds like its boiled dry and melted the solder, so it wont be making enough pressure to power the cylinders. If your not in with the North West Wales 16mm group, Im in the cheshire merseyside and east clwyd group so if you want to send the boiler this way I could ask one of the guys to check the boiler over for you?

I'm not cutting her up properly so to speak, i'm going to give her one more chance with steam and if the leak is still there then if i do anymore work on her i'll get a new boiler (if i have the time etc to overhaul her, A levels really do get in the way at times :x ) Even if the test does go well (which i highly doubt) i'm going to replace the boiler after a while anyway because i don't exactly trust it as much now! :? but the main problem if the boiler does get up to pressure is that the pistons are really stiff (it took 5 turns on the needle reg to get her moving!) so they need running in or new gas flow ones put on instead to save a lot of time and hassle
