Re: MMM Portgarth build.......Sanding sealer
« Reply #426 on: April 30, 2017, 04:06:15 PM »

Sometimes it pays to do your own testing rather than get incorrect advice.
A question was asked about sanding sealer recently and to prove a point I've treated a piece of ply here and primed it without issue or uneccesary expense


Also I have glued two pieces of ply to the sanding sealer with
A superglue
B aliphatic resin


Both feel solid but tomorrow I'll do a destruction test to see which gives with both
Either the glue or the wood

I do like to see a good bit of birch ply  O0 The tube should restrict all but the most active prop wash getting into your motor bay. As long as none of your electronic equipment is on the bottom of the hull then I cannot see any risk from water ingress at this point.

Looking good:O)

Update
Aliphatic is a complete fail as it cannot penetrate sanding sealer. So bare wood only!
So far the Zap a Gap medium CA is holding tight

Hi.

That was my question in the beginners section regarding sealer and glue.

Thanks for carrying out that test, I now feel much happier about masking the areas to be glued, in my case it's the underside of the ply sub-deck where it will be glued to the deck beams of my Boston Typhoon build.

Interesting cos I never read that  {-)  coincidence? Glad it helped you Les.


Personally I'm not sealing the underside or inside of anything but I do need to glue sections on top of sealed ply.

The jury is out but what do you think?
Painted or raw stainless

Around the edge of the yellow just to denote the danger area.

Great idea Brian  :-))
However the real boat has no line and it looks better in the flesh without any ridges  O0

If you paint it then every time you need to access the hull here the bolts will get scratched and will need repainting.

With good testing and the like before final fitting, the hatches should not need removing very often, so all being well the paint will not get chipped often. If the wind is with you then your installment will be so reliable that the hatches will only need removing when you refit her in a few years.

OK back to work!
Deck held up while tow line arrives, easier to fit and test before the deck is glued over.


So back to Superstructure.
I had to think about this for a while but then concluded the best place to continue was with the roof skin.
The reason being that this interfaces with EVERY other piece and clearly easier to fettle each of them than this in one.
I've been building to measurements rather than templates (guide only) so using this for reference.



I turned the cabin upside down on the 1.5mm ply to mark reference points that would help when joined up



I did of course run a straight edge across all the frames and sand until flat for 100% contact.


Now glued with aliphatic resin.  I've left a little spare ply overhang where there is doubt.

Re: MMM Portgarth build...... Engine hatch receiver switch
« Reply #449 on: May 01, 2017, 02:46:21 PM »

Engine access hatch with receiver switch used to fix it in place. So it can be removed for painting and fixed on last.
The box has a bottom on it so the screws go right through holding it down.
I have no idea what the hatch lid SHOULD look like so that's at a standstill until I get a picture  ;)
