Hi,

With the boiler test complete the safety valve was taken apart and clean and the stainless steel ball had its mineral deposits removed.  With this done the boiler was put back in its casing, filled with water, and connected to the engine for the first steam test of boiler and engine for many years. A shot video is at:

Take care Tony.

Hi,

For a bit of a change yesterday’s project was to make the aluminium fore deck for the Henley.  The thinnest aluminium in stock was used, which is thicker than the original would have been, if some thinner stock becomes available another deck will be made.
 
A cardboard template of the Henley’s bow was made, some sums were done to calculate how much larger the base of the template would need to be to raise the deck in a curve. A cardboard copy of the template with a larger base was made.  A section was cut from a sheet of aluminium and a set of rolls was used to create a tapered incomplete tube.

The larger of the templates was held around the aluminium tube with clear tape. A set of metal shears was used to cut the aluminium to the shape of the template. With a certain amount of persuasion with a file and leather mallet the aluminium deck was fitted to the hull.

There was evidence on either side of the hull for supports for the deck and a couple of screws were used for this. The aluminium deck had cut-outs made to locate on these screws. Whether the deck was supported in this way isn’t known.
 
Take care Tony.

Hi,

With the Henley’s fore deck made, there was the first attempt at fitting out the hull with the other parts of the model. The only major part needing further work is a means of securing the boiler into the hull. This done the model will be left until the warmer weather arrives in a few months so that it can be rubbed down and painted. With this achieved the hull can be fitted out again and hopefully a test in some water will take place. So, to the great relief of all, the next post on fitting the boiler will be the last one about the Henley for some time.
A video of checking out the engine propeller shaft connection can be seen at:

Take care Tony.

Hi,

I tell fibs this won’t be the last post I had forgot that the fore deck to allow for fitting had been made too long and needed to be cut back.  Also the temporary 8BA nut and bolt drive pin on the coupling needed to be replaced before attempting to fit the boiler.

Take care Tony.

Hi,

This really is the last post on this subject for some time.

The end of the boiler casing was rusty and rather fragile; to compensate for this a wider steel strap than Stuart Turner used was fitted.  First after dealing with the rust, inside the casing a brass strip was bedded into some Araldite and clamped in place.  While the Araldite set, the strap that the boiler sits on was cut, bent to shape, drilled and when the adhesive cured riveted to the boiler.
The boiler was fitted into the hull and an air-line was connected to it to do an engine test.  A bit of a video is at:

https://youtu.be/ur4u981HgeQ

Other than painting the hull the only other jobs to do are making some unions for the steam and exhaust pipes, but as I am out of suitable copper pipe, this might wait until the re-assembly after the painting is done.  Also, finding a suitable replacement for the asbestos blanket insulation that was glued to the hull’s side to protect them from the heat of the boiler needs to be done.

It has been an interesting build; as always if certain things were done again they would be done slightly differently; the funnel is a bit high, I think it is close to the correct size, the joggle in the boiler strap could be larger so lowering the boiler and possibly the front deck might be higher, which if thinner aluminium becomes available might be done.

Anyway with luck and a following wind sometime next year I might be boring you with the finished product and finding out if it sinks or swims. It would be nice to run it under steam in my test tank but the oil and water thrown about by the engine would be difficult to remove for painting.

Have a Great Christmas and a Healthy New Year.

Take care Tony.
