Building the Engine and Boiler
Below are posts related to the building of Arthur Leak’s marine compound steam engine as originally described in Model Engineer magazine and more recently provided via Camden Books (drawings, manual and castings). It will also include the construction of a oil-fired Yarrow watertube boiler, to designs from John King from the SBA (see links on right of home page)

This is the engine that will power SY-Befur, it is expected to produce 10-14HP. These post cover all the construction from Camden’s castings and the addition of pump and alternator assemblies for our particular installation.

Update on a snowy day

Another snowy day in Heggerscales

As April begins the weather returns to snow and cold, so it seems a good time to provide a progress report.

We are working towards getting Befur into the water for 2019 – I was hoping for April 1st, but (as always) I am behind plan. However, it really is too cold to be on the water, so we will remained chilled about our position.

So, here is a list of the main activity of the last few weeks:

Steamboat Crankshafts – Lessons & Manufacture Pt#1

Introduction

Those of you who have been following Befur’s progress will know that our first year in the water was marred by the failure of the crankshaft in the Leak Compound engine I built.

This post deals with the manufacture of a replacement, and the results of my research/experience into the approaches to building cranks for “small” (<20HP) marine steam plants.

2019 – progress to date

Well, I have been very quiet over the last few months, but some work has progressed. As I noted in October, we had a quite extensive list of snagging to address, not least the crankshaft re-manufacture…. well, while quiet on line, I have made some progress in the background, so I figured an update is in order: Continue reading

Going at it hammer and tongs!

Well, we have been working very hard to try to get Befur ready for the water, and this picture of me taking a break from boat building (on a blacksmith’s course seemed to epitomise what life is like….). – thank you Becca for the course, provided as a Christmas present, at a real Elizabethan forge!

Late- yes, Embarrassed – some, Nearly There – maybe

I noticed that I had not written anything since the end of March, and I guess (unconsciously) this was because I had intended to have Befur ready for the water on the first of April, and that clearly wasn’t happening – and addressing that fact in print was a bridge too far!

However, we have been far from idle, and I actually do think we should be there for the first week of June (fingers-crossed). So here is a quick review of progress in April and May.

More Electrics, “Decks” and Woodwork

Having craned the engine and boiler into the hull we have now settled the position of the key components and can start to deal with some of the remaining fitting out tasks.

We are still aiming for an April Launch, but in true project planning style we had not said which day in April, so we have a few days left. The following items have been addressed so far:

Electrical Installation
