Grahame,I think you have made the right decision here,the integrity of the wire fittings really over-rides the cladding,which always proves a right pain in that area,what I would do is to use two laminations of miralyte ply eased into place after first making accurate card templates and possibly glued in situ,where the wires enter the fuselage you could always then make small shrouds to make things nice and neat.
Nice modelling as always,it is a real pleasure to look at these pictures.

My original idea had been to use 2 layers of 1/64" ply but I wasn’t convinced that I wouldn’t get some de-lamination at a future date and as this area will be covered in Litho plate it would be difficult to repair, so I opted to use 1 layer of 1/32" ply instead; this is still quite easy to bend, even if it takes a bit (a lot!) longer, so long as the bend isn’t too tight.

Paper templates are used to get the shape before the ply is cut slightly over size. The ply is then covered with boiling water (a good excuse for a cuppa!!) and left to soak for a while, it doesn’t need to be too long. The ply is then tightly bound to a former using masking tape, the former should be slightly smaller than the finished bend, I used a 4" diameter tin for a 2¼" radius bend. Cover the ply completely with the tape and if the former is porous cover that first with cling film then leave it over night. The tape etc. keeps the ply moist; in fact it will probably still be damp in the morning. After removing the ply form the former hold it in its curve either using tape or pins while it finally dries if necessary.



The tank cover doesn’t continue all the way to the side plates. The front cabane struts go through the gap, which has a separate cover plate, so there will be no problem with the final soldering of the cabane assembly.




The gun trough needed a lot tighter bend but as it doesn’t really add to the overall strength just 1 layer of 1/64" ply was used.

PS Where would we be without Red Devil light weight filler!!

For those not familiar with 'Red Devil' filler which Grahame has used to good avantage here,let me explain,where as other fillers are usually made from plaster of paris or earth products made by British Gypsum,these are heavy as can be expected,Red Devil relies on micro balloons to pad it out,these tiny miniscule ballons are filled with air and very light,the balloons are held in suspension with water and gum arabic so once again when dry there is no excess weight,it will knife on or can even be brushed into awkward areas,you can build up complete fillets on wing joints by placing cling film on the join,then knifeing on the paste in layers,once sanded and a coat of clear lacquer it is very substantial.
One health warning with this stuff,the dust is deadly as it flies everywhere being light,so wear a dust mask always otherwise you will be coughing all day long.

Time for a little “metal bashing”; I just love litho plate me!

The first job is to work out the positions for the “extras”, I draw these out, in this case onto the paper templates used to cut the ply decking. I don’t bother drawing to scale but add the necessary measurements then I know for sure where everything fits when I’m in the workshop.



Drilling Litho plate is about as easy as knitting fog, the only satisfactory way to make holes is to use a punch. As each strap has 8 holes and there are 4 straps it is easier to make a simple jig. 2 pieces of ply bolted together then holes drilled through, with the litho clamped in place the drill bit is used as the punch, turned the wrong way round and given a tap with a pin hammer (protecting the business end with another piece of ply).



With the holes done it’s a case of adding the “rivets” and the trimming to size



The 4 straps ready for final finishing.



With the straps, bottom strips and rivets added the finished plate is ready for fitting to the fuselage.



I don’t worry about the odd dent or scratch, I my opinion they just make the finished model look more realistic.

I well remember spending hours trying to get the aluminium cowling for my Albatros just right then finding out that in fact on the full size each panel was individually “hammered” into shape so every one was slightly different with evidence of the manufacturing process clearly visible.

Nice tin bashing Gahame ! did you know the reason why Lindberghs 'Spirit of St Louis' had a turned metal cowling ? because there were so many dings and scratches in the metal they spun a wire wheel over the whole lot which gave that special effect,so as you say why worry about a few dings ?

Hello Grahame,

its always a pleasure to watch your building!
Hope that I can start the Parnall soon.

Regards

Hello Chris

Nice to hear from you again; glad you’re enjoying the SE5a and wish you luck with your Elf, any help and you know where I am.

I do hope you decide to start a build thread here as well as in Germany, remember, “a picture paints a thousand words”, but I’m sure you’ll have no problems; your English is excellent!

Grahame

Welcome Christian,I think we have had some correspondence in the past on scale subjects ?

Hello wonwinglo,

yes that is possible, I have been in contact with Grahame some month ago regarding his Parnall.

I`m really glad that I`ve found a forum for real modelling. Here in Germany there is so much of that Depron stuff and ARF kits.
Will let you know when I`m going to start the Parnall!

There must be more “recommended” ways to attach Litho plate than there are ways to skin a cat, they’ve all got their pros and cons, and I’ve tried them all! Purely by accident I’ve found what I consider to be the perfect adhesive for the job.

At work we needed some glue that dried clear for a project the students were working on, as I had some “canopy” glue in the car we tried that and it worked fine but some got onto the table which in turn got covered by a small tin foil container used to mix paint in. When it came to tidying up time the tin foil was stuck fast to the table, the old grey matter started to work overtime.



This glue is just the job for Litho plate, it’s like a mixture of PVA and Copydex; it’s thin enough to be spread thinly and evenly over the plate, which can be easily moved to position it accurately but within a short time it has good “grab” to hold everything in place. The icing on the cake is that it’s water based so a quick wipe over with a damp cloth before it’s really set gets rid of any sticky fingerprints etc.
