Made a start today on a 1=27th scale Piper Pawnee,took the sheets down to the print shop and got some copies,then stuck them onto cereal box card with Pritt Stick adhesive and then cut them out with a pair of nail scissors,I always make card templates as it suits my building when I want to make duplicates of my models.
I do not have a crop duster in my collection so thought this would make an attractive subject.
Was going to do this one for the competition but it seems t have vanished ?

Looks a lot like the cartoon plane in the Disney movie. I am sure it will turn out great knowing your talent.

There is a bright yellow Piper Pawnee sitting in a farmers field covered in weeds, just across the border in Washington state about a 15 minute drive from me. It's always sad seeing a little piece of aviation history just sitting there.
Peter
The blanks for the Pawnee,weather for sanding is holding me up its heavy rain here,I always sand outside,more 1940's Mosquito balsa,stock, getting low.
As there was virtually another fuselage decided it was just as easy to cut two sets of blanks and make that yellow one mentioned in the field,thats a real shame I could rebuild that.

Any chance of a photograph Peter ? I could make a yellow one,would love to see that.
Hi Barry,
I am not planning to cross the border but my sister in Law is going next week so I have asked her if she can take a few. I will post them when she does.
Peter
Thats great Peter,lookforward to seeing them,then I can paint one in yellow.

Plans have been submitted to the gallery for consideration,once they are accepted then these will be used as the basis for the competition model by myself,thank you,Barry.
Today the fuselage was carved and sanded smooth,the small block insert was to replace a section that a balsa beetle had eaten into ! this is former Mosquito balsa from my dwindling stock.

They say if ever you want to know how to reproduce something in miniature then look carefully at the real thing and see how they do things,here is a typical example the main undercarriage on the Pawnee is a cantilver assembly simple but effective in use,so lets take you through the easy stages,firstly raid your scrap metal box I always throw bits of metal in that box for future models,here is a piece of L16 dural from my aircraft days but even coffee tin will do bent over to make two layers if you wish,make a card template first and lay this onto the metal,scratch around the shape with a large needle and cut out with a pair of tin snips,fettle up with a file and tap gently either side with a small hammer over a miniature anvil to flatten out the curled metal,next mark where the bends go and then with a Dremel drill two holes where the undercarriage spreader bar goes,rough up the face where the undercarriage fits into a pre cut slot in the fuselage lower and epoxy into place,now while the adhesive is curing get some brass tube,mark and cut this to size then make three bends wherethe lower 'V' goes,feed this through the small holes carefully adjusting the spreader by squeezing the alum legs,lock into place with a tiny bit of cyno applied with a pin,the wheels will be fixed with dressmaking pins pushed into the tube axles,these undercarriages are strong and enable the heaviest of models to withstand the weight.

That works out great Barry. I have used aluminum for flying model undercarriage. Tin can would work as well. A "Heavy" landing could easily be repaired with plyers. The sanded fuselage look great also.
Lou
Hi Barry,
I just heard back from my sister in law the Pawnee is apparently no longer in the field. It could also be a case of a 20 something year old girl who has no idea what a Pawnee looks like, even if it is yellow!! I will keep an eye out for it the next time I go by that way.
Peter
Thanks for the trouble taken Peter,it will be interesting to see whether it has indeed flown ?
Barry.
The tail parts have been sanded on the Pawnee's and a slot cut into the rear of the fuselage,next they have been carefully glued into position and left overnight to cure.
Barry.
(http://smm.solidmodelmemories.net/Gallery/albums/userpics/10005/PAWNEE_TAIL_FITTED.JPG)
The wings for the Pawnee's were cut in half,then dress making pins which had their heads removed were sunk into the wing roots half way,thin cyno run into the pins locks them into place before offering up for a trial fitting and then finally glueing into place setting up the dihedral angle by resting the wingtips onto blocks of wood the right height,these are then left overnight to dry.

All aeroplanes need wheels so I set to work making some low pressure crop dusting type wheels turning them up on the lathe then lopping them off with a spare set for something else,the tail skid was hammered up on the anvil and the fork formed with a small pair of pliers,this was set at the correct angle and locked with a biy of cyno applied with a toothpick with a slit cut in the end.

The Pawnee propellers have been carved and fitted,plus the air cooling scoops in the nose were added with a hand held Dremel tool,to make the tail wheels punch out some discs from wood and push into the centre of the O-Rings,lay these onto a piece of polythene sheet and flood the centre with cyno,when cured drill a small hole for the mounting pin.

In case anyone is wondering where the wing struts are ? these will be fitted after priming and final sanding,the struts if fitted at this stage would make sanding very difficult especially getting into the area where they meet the outboard area of the wing,so for this reason on this particular subject they will be left off until the very end,what I will do to help adhesion is to glue and pin them with tiny dressmaking pins cut down and holes drilled through the struts and into the wing.
Those heavy struts are an important feature of the Piper Pawnee which is basically a low wing version of the Piper Super Cub with a new fuselage,wings and tail are identical to the Super Cub.
Barry.
How are things coming with your Pawnee contest entree? Looking forward to seeing the finished work.
Lou
Held up by the weather Lou for doping and painting,its just too humid at the moment to add paint as it just blooms with the dampness.
Barry.
Turning the spinners for the Piper Pawnee's weather awful here with high winds and lashing rain,no chance of doing any painting yet.
Barry.
(http://smm.solidmodelmemories.net/Gallery/albums/userpics/10005/PAWNEE_SPINNERS.JPG)
A bit of sunshine prompted me to nip down to Halfords and buy some high build primer and give the Pawnee's a coat,it did not go well as the paint absorbed the moisture in the atmosphere and bloomed badly,normally the primer goes off quickly but a quick quick check found the paint is still tacky,I will just have to leave them for a few days on top of the computer to help them harden befor an initial sanding session can be attempted.

That is too bad, but the weather is temperamental at this time regardless of the continent you are on.
Lou
The propeller spinners were completed and added to the Pawnee propeller boses,to dish the rear of the spinner so that it clears the pin I use an hand held rose bit,this simply dishes out the rear so it clears the pin used for the spindle,the pin simply floats inside the dished spinner.
Barry.

Nice idea Barry.
Lou
Concentrating on one Pawnee I made up an oil cooler,this has been fitted under the nose.

Looking good, thanks for the update.
Lou
I could always add wing mounted spraybars or a big duster hopper underneath this one,in fact I may fabricate some atomisers with a wind driven pump.
Brass tube set into a jig with the nozzles spaced out and soldered may do the trick,another challenge never done one of those before.
Barry.
