On holiday and bored witless due to unseasonal weather.
Here's a picture of the 8mm nitrile rubber bead. I'm sure it would be a great fit when sikaflexed in place but I've ordered 9mm for delivery when I get home to compare them. Either is massively better than the rubber other suppliers provide

Sorry but IMHO the edit is inappropriate as my reference is specifically about the fender supplied with the kit not a third party.


@timbo the 9mm was here when I got home and fits perfect :-))

Question.


Are there other instances of censorship I'm my thread? I had no email notification of this so presumably none regarding earlier submissions


To reiterate the situation. It is not the material that is in question but the fact that it is TWICE the size of the strake moulding in the GRP so not fit for purpose unless you grind off those mouldings.
If you are going to do this then it follows that you may as well fit C section styrene to accept a more realistic/appropriate rubber.
So MMM need to revise the moulding plug as they should have done years ago to amend all the other unsatisfactory features or asymmetry etc


If I don't post my findings its not of use to potential builders.

I used dressmakers pins Andy ( without the wife knowing of course  {-) ) I cut strips of plastic 1mm x 5mm wide drilled small holes then a drop of super glue on the pin before  pushing  through plastic. after I cut the excess off i dressed the underside on my belt sander, wet first before sanding  as pins get hot and melt plastic, as i said it took quite a while.

Another Question Brian.
When you've made up all your deck fittings what do you use to attach them to already painted finished surfaces?

Andy my fittings are fixed with stainless steel bolts if you look at the photo of the bow winch it has 24 nuts and bolts holding it down the stern winch is drilled and tapped into the gearbox and bolts fitted from under the deck the same as the bow winch bollard, my decks are 9mm ply covered with 2mm plastic card. the main the small bollards have 15mm brass pins fitted that go through the deck.all my fittings are brass and silver soldered, i have towed strait from the winches and they are still very secure :-))

Very nice.
Unfortunately all my fittings are resin cast. With some parts I've used 6mm brass bolts from below up into the towing lead. The gog is a stainless steel U bolt chopped down and will be glued with epoxy into holes in the deck. The other parts will only serve as decoration.
My tow line will run from a tube in the deck just behind the winch and will run over the top of the drum so effectively only serves to apply downwards pressure. I thought I'd attach this with silicon as it has a large flat surface.

I have seen quite a few models that are used for towing with systems like yours they work very well :-))

OK we can come back to this (lives in hope)


Recall I complained about the completely out of scale bollards ? This is my recent choice for the main deck/stern. Having received them I'm well please they are customisable to suite by cutting the tops off and adding a couple of brass rod pins.
Pictures will follow.
Cheap as chips  :-))

Excellent work there Andy.
Can you please tell me if your kort nozzles are square to the waterline or are they on a bit of a angle.
Mine the props want to rub so I'm trying to realign properly like yours.
This is my first build so I'm wanting to get it right.
Thanks. Don

Hi Don
Wether right or wrong I don't know but yes I made my Korts vertical at 90 degrees to the waterline. The Korts are 70mm and my props are 65/66mm
I made my stern tubes as shallow an angle as possible but the props will still be slightly angled inside the Korts
Another point is I used the 8mm super smooth shafts which are also 1" shorter than the standard ones which helps to bring my very big motors nearer midships.


There are pictures in the thread of how I achieved alignment

Andy

I just felt I had to comment on the fact that in the few years I have been on this forum, this build is by far the best I have come across with regards to detail, accuracy, informity and most importantly inspiration  :-))

In the last 4 nights I have studied and re-read this build twice in case I missed anything

Please keep it up

Can I ask how you cut your timber for when building things like the deck house?

The cuts seem to be absolutely straight and accurate and I am curious of your technique

Thanks

Dave
