Nick Smith’s latest motor launch – the ribs are steamed out and riveted

Using an ‘iron’ or ‘dolly’ to drive the nail over into the ribs. It is of course very important for the iron to be in the right place as the nail comes through!

Nick Smith’s latest project has taken a big step forward with the addition of her ribs, and our friendly boatbuilder has kindly sent in some more photos and a few words of explanation.

I must say the process looks like hard work, but no doubt many hands make light work, and entertaining banter too.

Nick tends to call the new project Bamboo Viper II, because she’s very much like an earlier boat he built by the same name – you can see earlier posts here and here

Here’s what Nick says about the latest phase in BVII’s construction:

‘Hi Gav,

‘Some photos of BVII yesterday.

‘We got a crew of five – luxury! – together to steam out the ribs on the new Bamboo Viper II. We pulled the first rib out of the steam box at 10.30am, and drove the last nail at 12.15am, which was the best time in all the years we have been building. We only broke three timbers, which was fine as the shorter lengths can be used forward or aft, where they butt onto the apron or transom knee.

‘So had some “spare ribs”, which I bent off the job to come in for odd repairs to broken timbers on customers boats.

‘The next task is to rivet up, I tend to do the upper-most four or five by myself (as my arms are long enough) then get my “oppo” to lie on the floor and “hang on” while I get inside the boat and rivet.

‘When I was apprenticed this job was done in one hit immediately after steaming had finished, so as the “boy” there wasn’t time to draw breath – as soon as the rib was in place I was straight under the boat (damp earth floor) holding on with an iron whilst the journeyman rivetted as fast as he could, no stop, no hesitation, no breaks, til we had done. And if ever I was on the wrong nail head as he drove or rivetted I was referred to by him in no uncertain terms as a ‘f****** c***’ so I learned very quickly to concentrate. This is not a teaching method I have carried on.

‘Gav, I think it’s brilliant what you have done and are doing with this weblog, many thanks,

‘Nick’

Thanks very much Nick – it’s particularly good to see photos of the riveting process in action. You must make a video one day!

More on Nick Smith’s latest motor launch

Nick Smith has written in with some more photos of his current project, which he’s given the working title of Bamboo Viper II, because she’s very much like an earlier boat he built by the same name – you can see earlier posts here and here. Here’s what he says about his preparations for putting in the ribs.

‘BV II is now planked up, primed inside so the frames have paint behind them and less likely to rot out the contact faces between rib and plank. I have located some good New Forest oak and have machined that up ready at 15/16ths of an inch by 9/16ths.

‘I have had to pick and choose to avoid knots,short grain and sap, and despite that usually allow an extra 25 to 50 per cent extra for breakages anyway. It’s a nuisance to run short then have to machine and steam a second batch or even just an annoying one or two to finish off.

‘The oak is ‘green’ – that is wet almost straight from felling. It steams better having moisture inside, and in the meantime the ribs are wrapped in wet cloth and then polythene on the outside until they are ready to go in the steam box.

‘The cost of the material is around £200! English oak isn’t cheap, and amazingly kiln-dried American white oak is cheaper!

‘It’s getting ever more difficult to get hold of all three key components – seasoned planking timber, good oak and copper fastenings. The price of copper has rocketed in the last two or three years.

‘I’ll send some photos of the steaming out process and the planked and framed hull when it’s done – it’ll be a couple of weeks yet. Meanwhile I have jumped ahead a stage or two and machined the gun’ls and risers ready to go in on top of the frames.

‘Cheers

‘Nick’
