The Build Starts

I have been collecting material for this project, I decided to build a hand pump first, this is the result. It is NOT my design I have used the design shown in Australian Model Engineering issue 200 with a few differences.

As I have a lot of silver soldering to do for the boiler I thought starting with the pump I might get up to speed as these are not as critical to the whole project and can be redone easily if not successful. I still need to practice more.

I changed the design somewhat I used hydraulic piston seal and O rings where the piston cyclinder connects to the valve body.and will feed water to the pump from a external water tank (to be built later).

First test it pumps to 250psi no problems I do have a very slight water leak to fix I think it is my silver solder joint on the valve body more practice needed.


A few weeks into building the boiler


In this post, I will elaborate on the next steps I took towards building a vertical boiler.




I purchased material from the UK and I have trimmed the copper tube to length I fitted a plug in one end and gripped with 3 jaw chuck, using a steady to trim each end.

I then purchased some 3 mm copper sheet to make the end plates for the firebox and boiler tube cut it with a jig saw roughly round then into the lathe to get round then I decided to try metal spinning.20181220_09145820181220_09153320181220_095553

This worked very well I tried as purchased first (Semi hard) but found it was stretching the sheet and starting to thin to much so I annealed and tryed again and was able to get very acurate sizes it only needed a slight skim on OD. Then the drilling results next photo.2019-03-20 11.12.04
