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….

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.

Launching & Initial Sea Trials

 “The Day” arrived!

There was no more putting off to be done – we had to launch her. We had agreed the rental of a swinging mooring on Ullswater with Ullswater Marine.  So on the 27th June (just over 7 years and 2 weeks since the first post here) we hitched the Landy to the trailer, and with our hearts in our mouth we set off. Actually, as neither of us slept much, and recognising it was “bin day” and aside from the normal, farm/post/school traffic down the 2 miles of single track lane, we also needed to dodge the refuse truck so we decided to set off at 7:30am.

Boiler tubes (in profusion)!

The tubes are ready to fit…!

After what must have been an epic session, Nigel and his assistants in the southern group of the “Boiler Collective” have now cut, deburred and bent the 600+ tubes for the three boilers we are building.

The pictures below show the extent of this activity, and the bending jigs they made…. (thank you men)!

We first made a trial set by measurement from and comparison to the drawings (yes, yes, I know “never scale from drawings“), we then test fitted these and they were good. So then the team cut the rest using an angle grinder in an adjustable jig. Then cleaned up the ends with a bench-mounted wire wheel, and finally bent them to the appropriate angles using the bender we “pre-calibrated” in the trial run.

EPIC….

Turning it over!!!!!

Well, yesterday was a momentous day! As noted in the previous post, I was totally ready to move on and stop filling/preparing the hull and see the inside!

More assistance from Nigel Thomson from the SBA produced an excellent result.

We propped the workshop roof with some Acroprops, fitted up a selection of chain hoists (thank you Graham for loaning yours) and supported the boat in slings. We then got inside and removed a remarkable quantity of ironmongery and stripped out all the molds…. Thank you Nigel for doing the majority of this work! Continue reading

A hull with no holes in – oh wait!

Well this months thanks go to Nigel Thompson from the SBA who noticed signs of wavering and  procrastination in my questioning about the sequence of build operations, and stepped in to put me back on the right track….

To go back a bit; you might recall that the game plan is to clad the hull outside and in with epoxy/cloth skins. Also we need to add the “keel” (aka “deadwood”) to the bottom of the boat after cladding, and the question was do we clad the out side, then fit the keel/propshaft/rudder etc.  then turn her over and clad the inside? or do we clad the outside, turn her over and clad the inside then turn her over and fit the keel and then turn her a third time or some other combination of things…. In the middle of this agonising it was suggested by others that the internal and external cladding need to be done in one season to stop the timber “shrinking away from the cladding” due to changes of humidity in the (half-clad) timber…. and then there is a land-rover chassis sitting waiting to be mated to my winter transport and then there are holidays and bike tours in France and then…… At this point the aforementioned Nigel stepped in and said “common lets get moving I’ll come next week and help with the cladding”. and so it was to be…..

Spring Progress & A Find

The clocks moved today, and the weather is amazing – must be close to 20c.

Last weekend Louise and I went to the AGM of the SteamBoat Association in Cleavdon (near Bristol) and had a really nice weekend – a very friendly and informed group of people. Also there was an auction (dangerous things auctions), but fortunately we forgot a cheque book, so I was unable to take advantage of many of the incredible bargains… 😉

However I did purchase the core of a condenser, which while quite large might make the basis of the one I need to build – 30lbs of Brass, and about 100 tubes for £10!!!

(pictures to follow!)

Sawing Straight (not)

Having clamped a pair of mould-half panels together, I figured I could just cut them out with a jig saw….

The "Offending" Saw - as always it's the bad workman who blames his tools!

The "Offending" Saw - as always it's the bad workman who blames his tools!

So off I set, slowly and carefully sawing along the line – 2 inches in I  encounter the first problem – there is so much dust I can’t see the line… At this point I engage “smug-mode” and pick up the shop airline, and with the spare hand blow the dust clear as I saw…

… I reach the end and discover (horror) that the b*&^&^y saw has cut at an angle to the vertical – and (double horror) this mis-cut has resulted in the lower panel being significantly undersize (we are talking about a ~5mm undercut!) grrrrrr….

I check the saw and the blade is square to the foot, so I am mystified…

A number of posts to the Selway Fisher Builders Yahoo group follow… (this really is a great group of people) and a deal of suggestions emerge within a few hours. These range from observations that cutting 1.5inches of chipboard in one go is too ambitious, thru to real Zen-like encouragement to chill more, take up a pipe and cut them with a Japanese hand saw – excellent!

So, I take some of my scrap chipboard (I just made a nice new bit of this) and draw curved lines and practice my sawing (by hand and other approaches) – including sawing it an inch oversize and improving my planing and surforming technique.

In the end two key factors emerge 1 – you cannot saw two at a time (you were right Graham) and 2 – I was going too slow! By setting the variable speed JigSaw to “flat out” and keeping my feed rate slow the desired results emerge….

I leave the workshop with three assembled and very “boat shaped” moulds – life is good again!
