Cheers, I am going to make a sand mold and pour the keel. I am going to fit a motor too, I have drilled the hole in the stern, and I need to pick up a shaft and a largish motor, what size was yours?

[Brian MuirParticipant @brianmuir84327]

The arrangement for the cross piece to be fixed to the rudder shaft looks interesting, not much room under the deck there? It also seems to be closed in by the decking so no access for repairs etc and no way to take off the rudder if I need to enlarge it to get more effective steering.

Hello Brian

I used a 540 motor with about a 10 to 1 reduction and about a 40dia prop

The rudder is a bit tricky, I seem to remember, incorporating a square drive at the top

The pivot shaft was fixed to the rudder and pushed up from below

Don't know why these pictures keep getting rotated??? Fitting deck beams, cabin coaming and I've used earth cable sleeve to carry the sail sheets to the servo.

Hello Brian

My IPad also has the habit of inverting the photos……Don't know why

Are you using an arm servo or a drum system?

Bob

[Brian MuirParticipant @brianmuir84327]

A drum, did you put steps down into the cabin? B

[Bob Abell 2Participant @bobabell2]

Hello Brian

I didn`t fit the steps……..I preferred to have plenty of space for the motor and jelly battery and sail winch mechanism

I also fitted a bilge pump……….Which nice to see in operation

For the winch, I used a drum servo, driving a gear sprocket, which powered an endless plastic chain around the inside of the hatch opening

The sail ropes could then be clipped anywhere along the chain

I have fitted an interior platform for the 600 motor, I plan to have the whole cabin lift off to give access to the electronics. One more level of bulwark planking to do, then the stern. I am going to use parts of a brass rudder system using a circular brass rod filed to a flat edge that will insert into the rudder.

[Bob Abell 2Participant @bobabell2]

Looking good, Brian

I notice you've got the prop shaft in position already

It may be worthwhile to resist the decking, before a trial hull leak test?

Is the kitchen, your workshop?

Bob

[Brian MuirParticipant @brianmuir84327]

Yes I will leave the decking etc for a while, I have to make and fit the lead keel, seal the prop shaft and the rudder post then a water trial! I work in the garage but I bring it in to let the glue dry as it is so cold out there at night.

[Brian MuirParticipant @brianmuir84327]

I have now sealed in the prop shaft and rudder post tube, fitted a larger rudder, but it feels a bit heavy (I suppose in the water it will be lighter) but I might sand it a bit slimmer. Ready for a float test when the aroldite dries!

[Bob Abell 2Participant @bobabell2]

Hello Brian

Coming along really nice now

Don't like the idea of getting the untreated wood wet……You might get some distortion?

Don't risk it

Bob

[Brian MuirParticipant @brianmuir84327]

Yes, that makes sense Bob, I had better prime and paint the hull first, it should cover any weak spots too. Cheers, B

[Bob Abell 2Participant @bobabell2]

Hello Brian

Looking at the last photo…….The rudder looks a bit oversize?

Bob

[Brian MuirParticipant @brianmuir84327]

I did make it larger than the one in the plans, I often find the rudder that may look nicely proportional isn't very effective. I can reduce it later after I have tried it out. It will also have a large section cut out for the propellor which will also reduce its effect.

B

[Brian MuirParticipant @brianmuir84327]

Two coats of primer and two coats of enamel satin finish, to let the planking show in the highlights.

[Bob Abell 2Participant @bobabell2]

Hello Brian

Progress indeed!……Time for a bath test?

Just a suggestion……I have always avoided the jet black hull colour look……It looks very aggressive on a model

Try a dark shade of grey and compare the effect?

Bob

[Brian MuirParticipant @brianmuir84327]

You must have reading my mind Bob, all dry inside after 20 min in the improvised dam. Not sure about the hull colour, interesting comment, I'll have a think before I do any fine detail painting.

[Brian MuirParticipant @brianmuir84327]

By the way, the anvil and tin of lead used as ballast weighed 12lbs, and she still seemed quite high in the water. When I cast the lead keel it will of course provide more stability and need not be the same weight.

[Bob Abell 2Participant @bobabell2]

Hello Brian

The designer admits in his write up, that he never used the correct ballast for some reason

Don't think he specifies the correct ballast weight

I only used 9 lb and it did sail high in the water, but the deep keel kept the boat upright

Being a very bulbous hull, you can go to town…….If you can lift it!

Bob

[Brian MuirParticipant @brianmuir84327]

A bit worried that the cutaway rudder has weakened it, may have to make another with some reinforcement, or use a smaller prop.

Quite a size with mast and bowsprit in place, They have to be removed for transportation or buy a bigger vehicle!

[Brian MuirParticipant @brianmuir84327]

I have also noticed there is not enough room under the deck level for the steering bridle on the rudder post as it turns. I will have to fit a raised section to sit over it. Not sure why I don't have room, I have actually cut away part of the keel so that the tube for the rudder post doesn't stick up very far.

[Bob Abell 2Participant @bobabell2]

Hello Brian

I remember the shortage of space at the tiller handle area

The attached photo may be of help?

Don`t forget the handrail capping
