Rebuild Started - Wooden Runabout - now finished Jan 2021
Re: Rebuild Started - Wooden Runabout
On my build I just used the screws to hold the ply in place while the epoxy set and then removed them as stainless steel screws will corrode if they are covered in epoxy because they need air to help them stay stainless. When you fill the holes force the epoxy all the way into the screw holes and when it's set it will act as a fastener you could also use a bit of fiberglass cloth on the inside to bond the ply to the frames for extra strength. If you still want to use screws put one in-between the old ones.

Re: Rebuild Started - Wooden Runabout
I agree, stainless are not great particularly if they are getting covered up later on. They are also relatively soft, I have broken off more than my fair share now .
Have you looked into silicone bronze? They are the preferred choice for many boat builders and about as good as you can get for "proper" corrosion resistance. They are however pricey so your idea for just putting them every 3rd or 4th might make things lighter on the wallet and I don't think it would be a problem particularly combining it with epoxy. I always like to have two methods of fixing just for peace of mind but many are confident that epoxies are up to the job on their own these days.

Re: Rebuild Started - Wooden Runabout
Thanks very much for your help chaps. It's much appreciated. I am going to go for Siliconebronze marine grade and put them in at intervals of probably three. I feel happier with this. I only want to do the job once and don't want things coming apart, despite the fact that I did do deep fills with the epoxy and made sure all the epoxy went down to the base on the hole etc. I took all the advice from this forum, also I rang West Systems technical people and they were very helpful, as was the Epoxy supplier who repaired boats themselves.
I have seen two UK websites, one does packs of ten and the other sells as singles. The packs are annoyingly out of stock in my size, but there is not much difference in the end in the singles price. But yes - still a wallet buster...............

Re: Rebuild Started - Wooden Runabout
Good idea, you can never be too sure and like you say, you only want to do the job once! Have you tried Robbins timber?

Screws are down on page 27, not sure how they will compare in price though.

Re: Rebuild Started - Wooden Runabout
I have ordered my Silicone Bronze screws and after hunting around have saved a few quid and got a good quote from:
angliastainless-stanton.co.uk
They don't have an order online website, but were very helpful over the phone and gave me a written emailed quote. Seemingly they are trade supplier to many others in the fixings business. Worth a phone call.

Re: Rebuild Started - Wooden Runabout
Possibly the same firm I just bought some stainless bolts from on Ebay, stanton-marine-stainless, also has another user name, stanton-marine-hardware and another, stanton-marine. As you say helpful and for me fast delivery.

Re: Rebuild Started - Wooden Runabout
A Spring update……… just in case anybody following this thinks the rebuild has stalled!....I'm keeping going.
Since the last update I have spent quite a bit of time out of the country, but in the time I have had I have completed fitting all the silicone bronze screws, back filled with West Systems and generally filled and fettled the hull and covered with a first coat of undercoat. I did this with the boat turned upside down on the trailer I built last year. I did that way for ease of moving about and working height, propped up and balanced on old motor bike tyres. See the new shots on the photobucket link:
http://s1342.beta.photobucket.com/user/ ... r/library/
The boat is now back correct side up on the trailer and ready for the inside/frame and deck refurbishment. Plenty done that does not show here, upholstery is ready to fit, seat bases and floors done, just a new floor panel to do for the rear section to the front of the transom.
Some questions looking for advice please:
A) The hull top is planked ply with false caulking (Big challenge to clean out and repaint in) The outer panel to the hull side was originally mahogany stained and was at some time painted over black. I have stripped off all the black and want to re-stain mahogany and varnish over, to give some definition to the rest of teak finish panels. Can I use some off the shelf stain such as Ronseal mahogany or should I use some specialist stuff.. I don’t want to buy big buckets of this, as the panel is only just over 2 inches wide and the boat is 12ft 6inch, therefore minimal quantity needed.
B) Also it had a rubbing strip fitted made from about ¾ inch half inch half round hardwood strip. It was broken and didn’t really fit correctly around the bow curve. Can anyone suggest a suitable replacement section - either metal or wood probably to keep in period late 1950’s.
I was thinking of dispensing with the rubbing strip and finishing the hull paint to a point meeting the mahogany stained deck panel – any practical thoughts?
Thanks for reading, keeping up to date with this and hopefully advice as above.

Re: Rebuild Started - Wooden Runabout
Progress is looking good! It's always nice when you turn the boat over because it really feels like your getting somewhere.
Robbins sell various sized timber mouldings that might be a suitable substitute for your rubbing strip http://www.robbins.co.uk/pdf/Retail_Pricelist.pdf (details on page 6) but like you say they don't bend/fit very well around the bow so perhaps a metal alternative would be easier to fit.
As for the staining part I haven't really done a great deal but I always cringe at the thought of using ronseal type products on a boat even if it is just a stain. Epifanes do a mahogany stain and it's available in small sizes so you won't end up with loads left over https://www.boatpaint.co.uk/cgi-bin/sh0 ... tml#a38696
Hope that helps.

I've used Liberon with good results on this ply Gadabout cartopper.

Re: Rebuild Started - Wooden Runabout
As always, thanks for taking the time to respond to my queries, much appreciated. I will use the pukka marine stain, type to be determined as per your recommendations. Looking at Rapiers result, I have decided to not just do the mahogany strip, but smarten up the whole deck including the teak with a stain. I think it will bring it up and provide a 'deeper' look to the final job with some definition in the grain etc. The ply veneered planking is now over 55 years old, so a splash of 'make-up' might give it a face lift!
Any thoughts on where I might source a small section... 3/4 inch..ish,,,rubbing strip (its only a small boat so don't want to overwhelm the thing with a large section), as an alternative to using the hardwood?
