Great stuff. Really useful.
Interesting that they do not want boxing in.
It is the mrrc ones that I intend to use on the Launch. Have Dayton ones on the tug.
Away at the moment but will check out you YouTube stuff when back.
Are you saying more open foam/
polystyrene
works better than the more dense stuff?
Cheers.

Warning
Going back to the warning about the knives and foot injury. A safe way to keep knives handy around the building board .Have a block of expanded
polystyrene
or Oasis Or similar .When not in the hand stick the knife into the block. To sharpen blades use a "Water of Ayr Stone ". I find nothing better . John O/T๐

Graupner ranzow refitting
I just thought i should mention for those of you wondering what all the
polystyrene
bits in the hull are for, as i mentioned at the start of this refit the boat did sink so i am not taking any further chances of it sinking again and i am filling all the empty space with
polystyrene
before fixing the deck in place.

Sanding down.
Evenin' Peter, I downloaded the instructions and the designer warns against using side cutters to cut from the sprues, as one is used to with more robust
polystyrene
. he recommends a razor saw.
I still think you should at least spray the hull, but it's your boat so 'If it feels good - do it' ๐
Ciao, Doug ๐
PS: My 50 cals + ammo belts should be here on Friday or Saturday. Wish me luck with the sprues and bullets at 1/35, even more fragile than yours ๐ฒ

1/11 scale Fairey Huntsman
The windscreen can be tricky. I used the .5mm PVC with
polystyrene
strips cut to shape and glued to the bottom edge. Had to use a perspex solvent/cement for that as not many glues are compatible with both plastics. The mast has a pin in the base and along with the side slots holds the screen in place for glueing, first with pva and then flushed with white acrylic gap sealer. The top of the mast is secured to the screen with a small screw. The moulding on the top of the screen is an โHโ section moulding heathen softened for bending, with a strip of veneer laid in the top and fixed with varnish. Finally the name and Fairey symbol were printed on decal sheet and varnished in place.
The first trial on the water was with an 11.4V lipo which went OK but i thought it could do with a bit more oomph, so ordered a 14.8V and that proved to be just right for a realistic scale speed, and it handles beautifully. Being single motor and rudder it doesn't have a very tight turn at slow speeds. Not too good for steering competitions! Too bad but good for just buzzing around.
The figures were built up with balsa and wire covered and sculptured in Fimo.
All in all I'm quite happy with the results. Definitely better than my first attempt; B/W photos.

Windows etc
The cabin windows are rigid .5mm pvc sheet framed with white
polystyrene
.5mm sheet. The tinting is from car tint off cut. I push fitted the glass flush with the outside and ran a bead of ova round the inside using a syringe and needle, then spray glued the back the frames and stuck them in place. Easy!
The seat frames are bent up from stainless wire and hard soldered. The cushions are just carved balsa.
Hatch covers are built as close as I could work out to full-sized practise, but I didnโt bother to make them actually moveable.

Start detail
More side strips on the roof in cedar, then onto the fun stuff.
For ease of access and construction I built the control console bulkhead on a seperate sheet of
polystyrene
card, mahogany detailing from old billings kit leftovers. Aluminium sheet from the tops of large Milo tins made hinges and louvres etc. I always save these as they are just the right thickness and softness for small parts.
For the compass; the bits box produced a ballbearing and a piece of brass tube just the right sizes. Heat gunned a piece of acetate and pressed it with the tube over the ball bearing. instant hemisphere for a handy scrap of aluminium tube as the base. All instruments are from a google search and inkjet printer.I parted off some tube for the larger instrument bezels.

Enjoyed making this superb kit from model slipway. Having to cut out the
polystyrene
sheets proved to be no problem. With 2 motors and bow thruster, thought it would be good for the steering competitions, but its a bit wide in the beam for our rather tight course. Working searchlight and rotating radar.

Aeronaut Pilot Boat
Hi Ed
It's coming along, but slowly. All I have managed to do is tidy up the re- glued sides and investigate fixing the bottom panels, which looks easier as they do not have to bend so much. I will attach some pics when I have achieved this task.
The good news is that I have rebuilt the mast on my yawl and will be stepping it tomorrow in time for Sunday at the lake.
The white sheet is in fact a
polystyrene
jig and does come with te kit. There are lugs on the frames (which are later snapped off), which fit into corresponding slots in the jig. This ensures that they are correctly positioned to take the keel and stringers. Makes life a lot easier.

trawl netting
HI Robert,
As Tommy3917 says Poundland or equivalent are a good source. Also the net bags that fruit and veg are 'packed' in. it depends of course on the scale but I have found many colours and mesh sizes this way. For floats or weights think of craft shops. You can get various sizes of
polystyrene
balls, beads and wood balls. Fishing tackle shop or car boot for small lead weight - but remember lead must be painted (best with two part epoxy)to avoid polution.

Finally finished ๐ . Rescue davit pivoted so that it swivels to bring in the catch. I've decided against a scale crew because the general opinion is that it makes the boat look too small. I may try to make my own smaller figures at a later date, probably using blue

Aerokits sea scout hull skins
HI Ian
Not sure what effect the dope would have on the expanding foam, it certainly eats
polystyrene
. if its still good, use it on the outside of the hull away from the foam, mix a little talc with it and it makes a superb sanding sealer over the wood grain.
I would still use epoxy in the bow area as thats were you tend to hit things, pond side, other boats etc.

If you can still get at the bow area, fill it with
polystyrene
packing foam. if its to late, do you know a builder? if he has used some spray sealing foam and has a bit left in the can, drill holes in the bulkhead and squirt the foam in. it will expand so don't seal the bulkhead again, let it settle, possibly 24 hours.
If you seal the inside of the bows with resin before putting the foam in, even better, this will double the sealing and give buoyancy as well.

HI folks,
I hope someone can help. It Is my first time using
polystyrene
and plywood for model boat building and I am having problems.
Humbral poly cement Is great for poly to poly. However, I have tried two different for poly to plywood. UHU plus acrylit and Pacer Z-poxy appeared to work but after three days poly peeled away from the plywood. This Is causing me a lot of re-working and not found an adhesive that works.
Can any one recommend an adhesive that will stick poly to plywood please ?

HI Tall Paul
There are other identical products to Stabilit Express.
UHU Plus Acrylit 2 is identical and available from Cornwall Model Boats. Mayhem articles on the same topic indicate that 5 Star adhesives also offer a product, probably based on methacrylate.
As Gregg says you need to roughen the styrene surface, this allows the glue to bond correctly into the styrene monomer.
I used to fly model gliders and can honestly say that Stabilit joints between wood (balsa/ply) and plastic never failed, even after my best efforts to destroy my planes on landings (er crashes) the glued joints remained intact ๐

Stabilit Express !
I use it all the time [see my Mersey build thread for examples].
Kindly make sure you sand the styrene first, to get a "rough edge", to help the resin adhere fully.
the glue is a 2 part mix, comes with a set of 3 differt sizes of "glue pot", so you simply use a different size as per you "mix" needs. put the number of "level" spoons in to the mixing pot, then fill up with the resin out of the tube, mix "caefully" untill all the powder is mixed in, or you will get a bit of a "cloud" !
you have about 10 minutes of movement time and dry in 2 hours. fully cured in 24 hrs and you can drill it, sand it, thread it if you so wish.
FULLY waterproof and rock solid once cured.
I have no hesitation in recommending it, it will stick virtually anything to anything and does not deteriorate with age. I bought an old boat, must of been 15 yrs old when I bought it, and that had been built with stabilit express, and the bonds were just as good as new joins. I am yet to get a joint of this stuff to break, usually the wood or styrene either side of the glue breaks first.
have attached a few picture examples of its use for you.
put it this way, IF this glue does not "do" the job you want it to, I'LL buy it off you ! thats how much I'd put money on it doing the job you want it for.
best of luck and remember to keep us posted on your build.

HI Gregg,
Thanks for that - yes it is Evergreen White Styrene Sheet which I was intending to use for the superstructure (Humbrol poly cement) and for hull sides with plywood hull bulkheads etc.
Have since read book by Richard Webb "Making Model Boats with Styrene" ; he recommends Evostick Fusion OR Stabilit Express
Another model boat expert recommended using cyanoacrylate (have found Loctite superglue)
Unless others have better suggestions will try these from Screfix down the road (No decent model boat shop in Camberley, Surrey).

polystyrene
is a bit of an unusual item to make boats out of, people use it inside as a bouyancy aid, incase of an accident. but it is such a soft material for external use and breaks/snaps too easily.
Are you sure you dont mean "Styrene" as in plastic type sheets ?

G'Day Tall Paul,
If all else fails I use "Liquid Nails". it sticks anything to anything. I use it on all my boats in one part or another. Check out your hardware store! it is waterproof and once stuck it stays stuck. if you happen to use a little too much it wips down with water, giving a very smooth finish.
hope this is of some use mate.

Totally stripped down!
Once all the pieces were dismantled it became apparent that some parts needed replacing, one of which was a bulkhead since the old one was warped beyond redemption.
I then proceeded to assemble the rest of the hull as per the instructions. For some parts of the construction I used water proof PVA but the main bulkheads were glued in with epoxy resin to ensure the structure was solid.
The last thing I did before gluing on the hull sides was to fit a block of
polystyrene
(shown here) into the front section. its more common to leave this cavity empty, however I thought that I might as well fill it with
polystyrene
so that if the worst came to the worst and the boat got flooded it stands more chance of remaining buoyant.
