Some different design of Aveling boilers.

  BE AWARE .  .there are three different engines on this page !!

New to the workshop is Aveling & Porter 7195 belonging to Martyn Blackburn. Here are a few photos of taking her apart.

 

 
 
 
 
 
 
 
 
 
The work will include repair to the hornplates, new box and tubeplate. 
 
Here are David and Sam having let in the repair plate to the hornplate, checking the next steps. This will be to mark out the stay holes.
 
 
 
Here is the completed box.
 
  
 
This is the repaired outer wrapper.
 
 
 
 
 
David threading stays . .  .he should look happy .. he has most of them done !
 
 
 
 
 
Shows one more crown stay to put in.
 
 
I'll be posting more photos as work progresses.
 
 David and Sam are currently working on the boiler for 'Buster', Aveling & Porter 10346 owned by James West. She had had extensive boiler work in the early 1980's including a new firebox with a repaired barrell, fabricated tubeplate and new smokebox. However the time had come to replace the 'front end' completely.

 

After you have recorded all the information you need, 'chopping up' is quite fun!

 

 
 
 
The throatplate on this design of Aveling is prone to cracking. You see many with repairs. Here we are doing NDT testing using ultrasound and also magnetic particle testing.
 
 
 
 
Here she is with the new welded barrell aligned and many of the holes drilled.
 
 
 
 
 
 
Now rivetted up.
 
 
 
 
 
You can see the four stays that hold the cylinder chest 'pad' to te boiler barrell in this photo. Also are the 'drain holes' from the area between the pad and the boiler barrell. One can be seen clearly on the left hand side where the swarf has yet to be cleared. 
 
 
 
 
 
 
 

Another Aveling . . . .
 
A 1928 Aveling & Porter D type, compound piston valve engine having new barrell and tubeplate fitted. In this case a welded barrell was fitted.

 Here the firebox has a flat top. The crown stays can be seen in the photos along with a set of hortizontal stays across the boiler. Essential that you properly wash the top of your box when you do your maintenance!

This design has a pressed 'pad' which is rivetted and stayed to the boiler barrell. The cylinder block, having a flat base is then fitted to this pad.

The smokebox is an extension of the actual boiler barrell. It is not a separate item as on some engines. The headstock then attaches to it.

In the tubeplate photo you can see the two longditudinal stays that go from the front tubeplate to the backhead.
