Hi Ron

I new at this forum, and have been searching for something like the OB20 for many years.

Simply superb.

 

Can you tell us approximately many hours you would have put in so far and apx cost of the materials used?

 

Its a gorgeous design and you are bringing that to life.

Well done

 

Best

John

Things are moving along on the OB 20.  I finally got back at it in January.  The laminated cabin top and pilot house top have been hard mounted. Windshield frame has been cut out and installed.  Side windows have been reinforced and ready for tracks.  Gunwales are laminated and mounted as well as a stainless steel bumper guard (same material as the keel strip).  The toe strip around the deck is also installed.  I have ordered an Evinrude Etech 60hp and a trailer.

  The next steps involve painting, glass, console, live well and finding some marine electrician to help me figure out the electrics.  I'll keep you all posted with the progress.  I have owned boats that have had electrical issues, and it can completely take the fun out of boating if fuses pop and motors don't start.  I took a course this winter on making paddles, and the port holes on Ronny,s raft could be converted to oar holes.(Just thinking out loud).

  By the way, whats with this "polar vortex" thing.  Mars has been rather balmy compared to Canada lately.  I have never seen this much snow or been this cold, ever! 

  Kind regards,

Ron

Hey Trev,

I think that I started at 45 degrees, but the scribing eventually changes the angle.  I didn't measure the angle after the first few pieces because it was easier to cut the top and bottom if the piece fit.  On occasion the top or bottom may have been an inch wider or narrower, and at one point I put a 3" strip in to maintain an adequate stagger between inside and outside layer.  It doesn't come with an instruction manual, so I assumed that there are no rules.

  I painted the top side off white because the grey was just too dark.  I also added a bunch of bling this weekend even though there are a lot of details to clean up.  There comes a point where I just want to see what it will look like.  I'll be in Costa Rica for the next three weeks. This winter thing up here has just been too much.  You never know what kind of crazy things I'll find for the OB 20 down there.

  Regards,

Ron

Ronnie,

 

She is really looking good.

 

Trev, there is no absolute rule about which angle the planks should be installed. The stern area is not critical which is why I specified using wider planks to help save time. The most critical area is in the flared bow where the sides are concave in both directions. I find that the best plank angle on this boat is to rake the planks forward from the chine to the sheer at about 30-35 degrees. Before I start to plank, I will take a piece of planking 6" - 8" wide and clamp it in place in the bow where the flare is greatest in several areas to see how it lies. I am looking at how the planks lie against the stringers fore and aft and top to bottom, perhaps more angle or less will lie better. If the plank wants to bulge between the stringers on both edges the plank is too wide. Once I am happy with the best angle, I will start at the stern and work forward to meet that angle, by the time I get to that position.

 

A couple of rules to observe. The planks cannot be too narrow but they can be too wide. If the planks are too wide the edges will swell up between the stringers. This is because you can force them tight to the stringers but there is excess material in the edges of the plank that must go somewhere.

 

Always have a clean fair edge on the forward edge of the plank. This is the edge that you will be scribing the next plank to. Usually, just ripping the planks carefully on a table saw will suffice.

 

When you put the plank in place to scribe, make sure that you are NOT edge bending the plank. You want it to lie exactly is it will when it is installed or the scribe will not be correct. Edge bending puts extra material on one edge of the plank causing it to swell out between the stringers on the compression side. It is best to clamp the plank in the middle first and clamp out to the ends making sure that it is tight to the stringers as you go to the ends. You will now be ready to scribe.

 

Do not edge bend the plank when you are gluing it down. If I have done a poor job of shaping the plank, I would rather have an epoxy filled gap rather than forcing the plank out of fair just to close a gap.

 

It is important that the planks have a tight glue line between layers, just fastening along the stringers is not usually enough. I usually staple between the stringers. If you do not buck up on the inside plank, the staple might push the inside plank away rather than draw it in tight. This is especially true if you staple near the inside plank edges.

 

This might seem like it is complicated but once you get the hang of it, it is easy.

 

Check out the planking discussions on the Ocracoke strings, here is a lot of good information there.

Hi Ian,

  A little more progress since I returned from Costa Rica.  The motor is apparently arriving this week.  The engine sales guy was worried a bit about transom flex with the 60HP evinrude, so another layer of 3/8" ply was added.  The transom is now 1 7/8" thick.  The glass and some trim was installed as well as a bilge pump, battery access doors and splash well.  Still lots to do, but I figure Ronny's Raft will see water this summer.  There is probably a good three weeks worth of detailing to be done, but like Miyot, I also want to go fishing and boating when the weather's nice.  I'm sure there will be ample opportunity in winters to come for details.

  Regards,

Ron

  Hi Striperick,

  The windshield gasket came from Spaenaur, (page K4) product #RW-92.  The sliding track came from Beckson Marine, and the port holes came from Tendercraft boat supplies (page 37).  Hope that helps?

  The engine arrived yesterday and I will install it this weekend.  

  Regards

Ron

  I can't believe that my last post was in the middle of April.  The engine did finally get installed closer to the end of April.  The helm  console was made out of an old medicine cabinet and a piece of walnut.  The fuse block and connections should all fit in there.  I found it necessary to build another console on the port side to fit both a stereo and the chart-plotter/GPS/fish finder. The red glove box is a chimney clean out and the bottom spare battery holder was a 40's milk box from a home demolition. All these little hatches and access doors were all relatively inexpensive.  Official marine access doors are just stupid expensive. It bothers me that putting the word "marine" in front of any product is some kind of licence to triple the price.  I could have just made all these doors out of plywood, but it wouldn't be nearly as interesting  The consoles do look a little eclectic and weird, but they certainly are original. I am slowly running out of scrap pieces of lumber in the wood shop. This OB20 has darn near every species of wood that is commercially available.

  The seats are all mounted on swivels for doing whatever is on the agenda, fishing, chatting or travelling. The speakers are mounted in the seats and can not be seen in the pics.  Several conduits run from the transom to each console and between all seats.

  The engine works, but the rest of the electrical needs to be installed.  This is something that I don't care to play with.  The downriggers and some other things that just hook on to the battery with in line fuses are fairly simple.  The lights, horn, bilge pump,stereo etc, I have no interest in.

  I am hoping to have Ronny's Raft in the water by July 1st.  I'll keep everyone posted.

Regards to all

Ron

Hi Ronny- she looks great.  I am considering a build and thinking about power options, etc.  I will be interested to hear what the performance/fuel usage is with that motor, especially compared to the specs on the plans with the 25.  Looking forward to the updates!

  My little project finally came out into the big bad world.  The Canadian registration arrived last week, so off to the sign shop we went.  After that, Ronny's raft was chauffeured up to Doe Lake to have the electrics rigged up.  Hopefully, it will be ready to have a test run on our July 01 Canada day long weekend in Blackstone Lake near Parry Sound.  If all of this goes as planned, the OB20 will reach it's final destination in Wiarton the following weekend.  

  Regards,

Ronny B
