Re: Lofting the Brewer catboat
Looking good Jim! I'm assuming that the lower bolts on the EA casting go all the way through to the vertical curvey flange of the newer cast angle, and that the two lower shots are 'in-progress' so to speak? Or is this one of you hidden through bolt tapped and welded tricks?
Merry Christmas mate!Jarndyce and Jarndyce

Re: Lofting the Brewer catboat
The bolts are tapped into he bronze angle, run through, then ground and filed flush so they can only be seen by close inspection.
This was done solely to hide the fact that the holes were drilled through the timber too low and the nuts would have looked "off".
It's a sickness, I tell ya.
Merry Christmas, y'all.Comment

The engine beds again blocked in position for scribing The template gives an easy visual reference of how much wood needs to be removed from the tops of the floor timbers to allow the engine to fit.
The template indicating that the engine beds need to be notched for the flywheel to clear.

Re: Lofting the Brewer catboat
Now, I'm wondering whether the triumvirate of holes on the aft bedding flanges are there for flexible arrangements, or there because they are all required to be used? Your beds appear to be softwood as well, or are they templates to be replaced with something harder and more expensive?Jarndyce and Jarndyce

The engine beds are indeed, softwood. I wish that the pieces were a little longer and wider, but they are what they are. I might use them or I might not. They are old growth Longleaf Pine, a wood with some good qualities where engine beds are concerned. They reached their equilibrium moisture content decades ago, so there'll be little seasonal movement up and down. The wood is dense, rot-resistant, strong and not likely to crush under the lugs. In addition, it has more resilience than a hardwood, a good quality under a thumpy little engine like the Sabb.
I have some more Longleaf, but it would have to be glued up to size.Last edited by Jim Ledger; 12-26-2011, 08:08 PM.Comment

Re: Lofting the Brewer catboat
Speaking of "thumpy", from much of the above I infer that you're not making any accommodation for vibration-damping engine mounts.
Is there simply no way to accommodate them, or would they just be a joke on the Sabb?People today will buy a car with square wheels as long as the steering wheel is heated.Comment

Re: Lofting the Brewer catboat
I'll be bolting the engine directly to the beds, actually to a couple of half inch thick wood pads on top of the beds. This is in case the keel, floors and beds expand under the engine necessitating a lowering of the engine after a period of time.
Any kind of vibration dampers will reduce the possible thickness of the beds. Because of the shallowness of the hull and the impossibility of moving the engine forward there is not much wiggle room where the floors under the engine and the beds themselves are concerned.
Besides, that Sabb thump is like a heartbeat, a nice steady slow heartbeat, and it's kind of enjoyable, especially at 300 RPM.Comment
