Spa building

Trouble is, I like learning, and the best way to learn is from people who are doing it. I can roll one handed (probably, I actually gave that up years ago) and stoke about a gallon of tea a day.

Does that let me into the secrets of how to master this art?

One handed? Youre a boatbuidling guru!

Last year I went to the International Boat Building College in Lowestoft. Using the knowledge I already had, I was able to get huge benefit from this. So much so that over the past 6 months I have undertaken the full restoration of an 1862 Itchen ferry!

If you have the time and a little cash it is a year full of oportunity. Be warned though, the politics in the school are somewhat bizare and you can only get the best out of it if you ignore the bull and push for what you want.

Also met some fantastic people there from all over the world and of all ages.

Sorry about the spar thing, just not able to articulate my method. Perhaps you could be more spesific about the question.

OK, articulating question

Putting two pieces of mast together. I suspect neither will be simple cylinders, usually have tapers of some sort

How do you work out how to cut the bits to make the two pieces of wood match?

I have a big old jack plane, which suffices very well! I use a power plane first, then finish with the jack and a smoothing plane for final titivating

Luckily for me, there was no taper. The scarphs are quite near the bootom of the mast.

I built a 43ft mast for a Broads cruizer last year.

It was made in two halves and each half was made from 3 lengths of timber to achieve the length. Before making the scarphs the timber was planed down to a little over half the thickness of the mast, so were parallel and equal in all dimensions

I then marked out and cut the scarphs which was just a case of marking the lengths and striking a diagonal between them.

With the scarphs glued together, I marked a cetre line down the two halves and set about marking out widths and tapers.

With the tapers cut and the centre hollowed out I then glued to two halves together.

Only then did I start to shape the mast. A nasty teardrop shape that nearly killed off my brain cells.

Cheers, makes more sense now. I think

hello
I have a 9 tonner. my mast was split into its constituent parts two years ago. it was glued with rescorcinol although i don't know what type other than it was re! the whole mast was then screwed and the screw holes plugges. it looks good and i stronger than it ever was.
