Tube Expanding and Economiser Headers

Just an update on progress with the boiler and other (interrupting) activities.

Tube Expanding

Nigel was good enough to make the trip north and assist with the tubing of the first boiler.

This was actually a simple, if repetitive, job.

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….

Shiny Things

While we await the 600+ cut and bent boiler tubes from the other members of the “Boiler Collective” beavering away in Sussex, we went back to the engine to try and close off the final list of “to do” jobs….

I think Cleading is the official word for this, even though WordPress objects! Continue reading

Boiler Begins!

Sorry for the long silence, we have been working hard to relocate to Cumbria and convert the garage into a workshop – with that approximately complete it allows me to get started on the boiler for Befur. So this post concerns itself with this topic. Continue reading

More fitting out – and symmetry

Just a quick note, the last week or so have been dedicated to the building of the cabin on Befur, and the first stages of internal fit-out.

This has involved the fitting of the cabin sides (as seen in the last post’s pictures), and the fitting of internal bulkheads, (e.g. the walls of the loo and heads for the bunks.) This has involved more “spilling” to get the shapes from the hull for cutting of the bulkheads (a remarkably accurate process) and fitting these too the hull using epoxy filets. Continue reading

Relief Vales and Drain Cocks

An experiment – Steam Operated Combined Drains & Relief

Much earlier in the process I baulked at drilling the cylinder castings for the cylinder drain cocks because they looked hard to drill with out risking damage to some rather expensive castings. Moreover, previous experience with manual cylinder drain cocks on the loco had been poor (leaky, difficult linkages etc.) and on the steam launch most people seem to opt for 4 manually operated cocks which involves a deal of “faffing” in use.

Fuel Tank, Mast Structure and Galvanizing

This is a hotchpotch of notes on progress we have made in the last few weeks.

I am now focusing my attention on the internal fit-out. We need to get Befur in a state to move her on a trailer to our new home in Cumbria in August, this is adding some needed pressure, to ensure we get everything done in time… Continue reading
