New d32 boiler hopefully!Hello again just got my bits to make my new boiler
 
|

|
what is actually wrong with the old one?
|

Both end caps have got holes in them and also boiler .No worries ill knock a other one up . Not the best boiler to start with for my first time !!Did have a GO at getting the old end caps off but they have been braised on .Should be good fun making a new one !!

how are yo going to make new end plates?

would it not be easier to have ago at patching the the holes up with silver solder, it does not matter what it looks like as it is hidden?

It might be easer but it won't be as much fun.

But isnt the sign of a true engineer to do everything as simply (but properly) and with only using as little masterial as possible to do the job

Does it have to be silver soldered then?

I suppose he could plug the holes with washered screws, but then again it would end up looking like something I did so nevermind.

as it is part of a boiler that contains water the temperature will never get high enough to melt soft solder so you can use it. silver solder or hard solder as it is sometimes known will produce a much stronger joint and would be my preference to solder patches on.

True but it would be a hell of an easier job to soft solder it

Not really, there is no mystery to silver soldering, it is the same process as soft soldering
1) Clean Everything as well as possible
2) Apply a good metal flux
3) Apply heat
4) Add only enough solder to get a good joint
5) Do not overheat
The only difference between the two is the amount of heat needed to flow the solder.

That is where number 5 comes into play.

And too, it is old, sick metal if it has developed holes.
Too bad it can't be replaced with a factory boiler--less fun,
but the engine would become valuable again for resale that way.
But that's just not a practical option, I understand.

I dont know the price, but I would bet that Wilesco sells replacement Boilers, at least for models still in production. However, obtaining one might be a hassle.

... they do, but not for the D28 and D32, since they stopped makimg them in the 80ies.

Is where it can go wrong, it is easier to soft solder on that basis

Better get practising then,
easyflow 2 melts about 650 degree and brass at 800-1000 degrees depending on type of brass. Thats a lot of difference to get it right. Most people use a flame that is to small and hot, this produces hot spots that can burn the brass. Try using a large soft flame to get the whole joint hot. Less chance of burn out that way

Never really encountered problems when soldering Mamods some can be tricker than others but it's generally easy on a Mamod boiler
SE3's I can crack open easier than a bottle of beer

i am not saying you dont have the skills to solder as i am sure you have, soft solder goes at less than 200 and you can get a boiler hot enough to solder on a kitchen gas hob. I am saying that there is no real mystery to silver soldering, practice makes perfect joints and you should not be worried about having go at it.

Well the only real one I would need to silver solder right now is one of my G+G SE3's
Might have to try it one day whats the worst that could happen?

Just practice on a bit of scrap mate you will find its a lot easier than you think.
I use solder that is 50%silver makes a great joint

I tried silver soldering ONCE MM...it was on the seam of a Jensen boiler. I was trying to heat the end cap enough to melt the silver solder within. By the time I got the solder to liquify, I managed to burn a hole right thru the end cap ruining that boiler completely  .
For me...THAT is the worst that could happen!!!

Hello ive been having a go at soldering ,been re soldering the pipe work on the water pump it got damaged in transit from Germany!
Not turned out to bad at all ,and pipe bending as well will post some pics very soon .Hopefully next week should be on the lathe
to "knock that boiler up" REALLY REALLLY REALLY WANT TO GET RUNNING FOR FEBURDAY!!
