Three Months and Counting!

We are feeling like the end (of the first phase) of “project Befur” is in sight – we have set a goal of having her on the water in April – the remaining 90 days appear to be passing at some speed.

This time I wanted to document the final work to get the engine and boiler ready for installation in the boat, the electrical system and Louise’s work on fitting out. Continue reading

A final video: Everything running on the bench

First Fix the Bugs!

Following on from the Boiler test, and a quick trial we identified just over 20 items that needed some attention. So a week later, with all these items fixed (from leaking valves to painting and plating valve gear components), we are ready to try again. Continue reading

A Boiler Full of Steam

Well the 10th November 2017 marks a major milestone – the boiler passed its initial inspection and steam test, and is now certified for use. (big smiles all round).

Picture of Engine, Boiler Etc. ready for test

Sadly, everything was too frenetic to take pictures during the steam test – but here it is just before we pressed go!

John, our inspector from SBAS Ltd (the SBA’s Boiler Inspecting Company) had been booked to arrive at 3:00pm – at 9:00am I set about final sealing of the try-cocks on the sight gauge – at 1:30pm I nearly called to cancel the appointment as no amount of fiddling and fitting would make them seal, with a constant drip from each of them at anything above 50psi 😦 Continue reading

A Plumber’s Nightmare & a Real McCoy

Over the last few days we have encountered the two items mentioned in the title in real life, in a slightly stressful way.

The Real McCoy

One of Elijah McCoy's displacement lubricators - actually this one was made by the Detroit Lubricator Company.

One of Elijah McCoy’s displacement lubricators – actually this one was made by the Detroit Lubricator Company.

While Wikipedia suggests two origins for the phrase “The Real McCoy”, the most well documented version relates to one of the brass beauties shown here.

It is a displacement lubricator patented by one of Elijah McCoy’ in the 1870s in America.  These devices perform a simple, but vital, role of providing internal lubrication for steam engine cylinders and valve gear, but they do it using an apparently impossible process. Continue reading

Boiler Gauge Glass and Boiler Fittings

Finished Gauge Glass

We decided to make the sight glass for the boiler following John King’s design, with slight modifications. Ian Cross of the SBA was very helpful and modified some existing patterns he had for “normal” reflex gauge glasses to suite rear-entry installations, and had 3 sets of these cast for our “boiler making syndicate”.

As it happened he made the castings with larger/longer mounting “lugs” so I decided to try to make the gauge with the cocks integrated into the body (as opposed to separate valves as drawn by John). This was a quite stressful decision as the cocks are not easy to make, and any errors result in a scrapped casting, but none-the-less I am quite pleased with the result. Continue reading

Boiler Insulation and Funnel

Just a quick note on recent days’ work. We have been insulating the inner boiler casing and installing the funnel (at a jaunty angle)!

The boiler has two casings- one surrounding the burner, tubes etc. (the hot stuff) and an outer one of wood, with an air-gap in-between to keep passengers safe. This also includes a double skinned chimney (also to keep people safe – Lou has quite a scar from another steamboat where the funnel was not lagged or double skinned). Continue reading

Mid 2017 Update

Progress since April

Well, it seems like high time I provided an update, as the last one was in April!

At some level it feels like not much has been achieved, but that’s because a lot of the work has been “bitty”, finishing up jobs and tidying up items that had been hanging around for a while – and then there was the distraction of needing to design/build a new garden shed (the last one literally blew down – the joys of living 900ft up in the Pennines!).

So here is a list of the items I can recall completing…. Continue reading
