Spring ’24 – work so far

Well, as we reach March 2024, I should jot down some notes on the work being undertaken this winter.

Work done

We made a list of jobs to be done back when we fetched Befur out last autumn. The completed work is shown below in Green, still to be done in Red:

  1. Cleaning the inside of the boiler, removing oil t0 improve efficiency (reduce fuel consumption) Done – notes and video here
  2. Cleaning the inside of the condenser, for same reasons and improve vacuum – Done – notes with Boiler Work above.
  3. Remachining the LP crosshead and glands as it is now clear that this is the principal source of the hateful knocking the engine makes. – LP Done – see below
  4. Replacing the pump drive worm box, as this is at the point of failure, and adding “assistance springs” to reduce the torque requirements on this box, to extend its probable life! (probably another post here too). – See below
  5. Replumbing the condenser to be “contraflow” as this should improve it’s efficiency too.
  6. Attempting to design and fit a clutch to the prop drive to allow it to freewheel when sailing.
  7. Attention to paint and varnish
  8. Possibly fitting a reinforcing  inner fore-deck and removing the anchor chocks and resealing to improve weatherproofing.

Hauling out end of 2023

Review of the Year

Actually Sailing!

Well we had quite a good year, but a rather wet summer and too much playing with old motorcycles meant that Befur saw a lot less sailing and steaming than planned… but she performed pretty well.

The pictures below provides a summary of some of the activities we undertook.

Projects

During the year we undertook a couple of projects, firstly to make a better whistle, and when that failed making a siren for Befur (and that’s the subject of another post). and some maintaining things, (remaking the auxiliaries manifold, hunting for vacuum leaks) still that search for vacuum and silence!

Winter Work

In overview we are planning to do the following things in the next weeks:

  1. Cleaning the inside of the boiler, removing oil t0 improve efficiency (reduce fuel consumption)
  2. Cleaning the inside of the condenser, for same reasons and improve vacuum.
  3. Remachining the LP crosshead and glands as it is now clear that this is the principal source of the hateful knocking the engine makes.
  4. Replacing the pump drive worm box, as this is at the point of failure, and adding “assistance springs” to reduce the torque requirements on this box, to extend its probable life! (probably another post here too).
  5. Replumbing the condenser to be “contraflow” as this should improve it’s efficiency too.
  6. Attempting to design and fit a clutch to the prop drive to allow it to freewheel when sailing.
  7. Attention to paint and varnish
  8. Possibly fitting a reinforcing  inner fore-deck and removing the anchor chocks and resealing to improve weatherproofing.

Wow, that looks like a lot of work when you write it all down!!!

A review of 2022 & Happy Christmas

Waiting to Tow Aurora back to Ferry Nab

An apology – we’re not dead!

Well, I guess that’s what progress looks like – I haven’t written a thing since we re-launched in May, so it’s actually been going rather well! But a tentative phone call from friends in Australia to discover if Befur’s lack of posting indicated we were no longer shuffling along this mortal coil suggested it was time to write something!…. But, all is well, Lou, I and Befur are in good fettle….

Getting to the end of the worklist

I’m falling behind! No progress update since January – sorry.

We have been working hard to get her ready for re-entering the water… This winter’s workslist has turned into quite a major refit.

The list below shows the work we are undertaking, and all is completed except installing the engine and the work on mast and rigging.

Valve Setting on a Leak Compound

This time we are looking at how to fix the problems with the Leak’s valve gear design. This is now part of our Leak Hints and Tips section on the known errors or problems with Leak design……

As we get to the end of January 2022, the tuning/rebuild/shopping of Befur’s engine continues, once this is complete we can get on with the list of hull and fittings-related work. But it seems we should at least explain what work the last few months have contained…

Progress – a new scotch crank pump drive

A last quick post for the day, then it’s back to the cold workshop….

The pump drive on Befur has been an on-going source of angst and failure… So we redesigned and rebuilt it!

This appears to be much better, and pending final cleaning, plating etc. here is a video of it in action on the bench!

Winter Work (some progress)

 

 

Well, we have been working on the list we made in the last post, and have some positive news, and some better understanding of the problems…

Wear

I spent a couple of days with the engine on the bench and a dial indicator attempting to find and measure the wear or absence of same…. We have a page or two of measurements…

SBA 50th Rally

A memorable week: variable weather, lots of friends,
some mechanical mayhem

The first week of August is “Windermere Week” for the SBA, where a number of members gather, with their boats, and a number of marine and social events occur. This year it marked the 50th anniversary of the SBA, so more jollity was ordered and delivered. Continue reading

Is this the end? Probably not!

Timeframe missed a bit

Well, looking back the first post here was on 8th June 2011, and we aimed to finish and launch by 26th June 2015 – planning was never my hot spot! We did change the goal posts in mid-flight (adding a sail, loo, etc, and stretching her from  a planned 16ft to almost 27ft to get everything in, but hey we did get there!), and on the 20th July 2020 we took her for a steam and sail on Windermere with a cameraman (Roger Heise from the SBA) on hand to record her 2nd trip under sail (thank you Roger).

Notes on the Steam Bit

Before I inflict an album of sailing photos on you, a couple of notes on the steam side, especially for Leak Compound builders…. Continue reading
