Hawker Hind (conversion from vintage Aeroclub Demon, 1/72) --- Done


Old Man

Recommended Posts

A while back, I took an old Aeroclub Demon off the shelf and built it pretty much 'out of bag'....

It was a lot of fun, and got me to thinking of doing something with several more of these and its mates I still have left. When I saw the time-frame for this Bomber Command Group Build had been extended to 1936, I decided to turn one of my remaining old Demons into a Hind.

Here are the bits out of the bag along with an old ModelDecal 'Hart family' sheet, which will provide marking for a Hind of No. 103 Squadron, reformed in summer of 1936 as part of the Expansion scheme.

I got started on the project yesterday....

This picture shows some of the necessary conversion elements; filling in the starboard gun-trough and letting in windows on both sides. The latter will get a good polishing soon. The other major element of the conversion will be contriving 'ram's-head' exhausts.

This picture shows start of some external detailing on the interface between the bomb-aimer's and pilot's stations. Nothing major, but what is provided benefits from a bit of tightening up. As with the Demon, I intend to put a pair of lads in Sidcots in place in lieu of detailing the interior. The sides are awfully thick, and I do not have the time to sand them out properly.

Good for your uncle, Sir! That is a beautiful job.

This is an interesting one, and it will probably be the smallest model in this group build! If it comes out even half as good as the Demon it will be spectacular!

Regards,

Adrian

Thank you, Sir. I expect it will be at that.

I have got a good deal more done on this, though it may not appear to be much --- once the preliminaries are in order, this will come together rapidly.

The lower wing is just dry-fit in place for the picture. I took some 're-fit' pains with the lower wing to fuselage joint, owing to the proximity of the windows to its seam, and the need for a smooth bottom in this area for detailing the bomb-aiming position externals. The shims were blocks of 3mm sheet, trimmed out, with the 'center' of the wing piece made shallower and reduced a bit in chord.

The windows have been polished on the inside, but not yet on the outside.

The slots for the Demon exhausts have to be filled for proper representation of the 'ram's head' manifolds.

The blisters are made from bits of 2mm sheet, mostly shaped before fixing to the model. On this example of the old kit, the blisters were definitely undersized.

To get the gun ring, I made a disk of thin plastic, glued it on after the fuselage was closed, and then cut away the center with a new knife blade till only the ring was left. The holes in the partition between the cockpits are not yet finished.

Next order of business is what I have put off so far; the tricky bit of making the needed exhaust manifolds....

Great to see the progress and how you are handling the various conundrums!

And many thanks for your kind words. Uncle Mo passed on several years ago and every time I see the Hind it brings back fond memories.

A good deal more progress here, Gentlemen. Ready, in fact, to begin priming and painting on the next pass.

First, I tackled the element I had been putting off, namely the 'ram's horn' exhausts. This took a good deal of time....

IMG_6108_zpsb783c643.jpg

This illustrates the early going: bits of 1.5mm round cut to a hair under 13mm length, and blanks for the individual exhuast elements, which began as 3mm x 5mm pieces of 1.5mm sheet, and have been given a very rough shape. They are considerably oversize at this point, bit it is always easier to remove than to add in this sort of thing.

IMG_6109_zps586c9a8c.jpg

Here the exhaust elements are much nearer their final shape, and have had their edges rounded to proper section. They are still over-sized, but this is mostly in their length, and this has had the advantage of making them easier to hold and work.

IMG_6111_zpsef27abd0.jpg

IMG_6125_zps7f0045f4.jpg

These last show the pieces in the final stages, with the over-length trimmed off (about 2mm gone), attached at proper angles to the carrier rod, and fiddled with here and their to give at least the appearance of uniform size and curvatures.

I have not decided which will go on which side yet, and so have not put in the outlet slots on the undersides.

With this 'tricky bit' in hand, I turned to completing surface detailing on fuselage and upper wing, correction of the upper wing in one particular, work on the tail surfaces and area, and attachment of the lower wing and tail-plane.

Various louvers and scoops were replaced on the nose, a couple of small tear-drop fairings added, as well as the small scoop under the nose.

The lower wing was attached, shimmed where needed, the whole area on the bottom got smooth and level, and the bomb-aimer's sliding hatch put in (rails are 0.25mm rod, hatch is from a roll of 'furnace foil' from the hard-ware store, very useful stuff).

The holes in the panel dividing front and rear cockpits were finished with bits of sheet shaped to quarter-circles put in at the tops (fixing a slip of the knife made earlier).

The tail area received a good deal of treatment, not all of which shows up in these pictures. In aeroplanes of this period, there is generally something odd going on if you look closely at the tail area, and Hawker's provide the epitome of this. The tail-plane was adjustable, rotating on the front spar, so there needs to be a wedge of daylight under the tail-plane between it and the fuselage, and also over the tail-plane, between it and the bottom of the fixed fin. Small bits of rod (the traveling jack that moves it) are exposed as well. The bracing of the rear spar moves up and down as a unit, so there is a small cut-out in the vertical fin exposing some of this, to which landing wires are anchored. The vertical fin itself is off-set a bit to port (to balance the motor's torque). Scoring through the division of rudder from top of the fin allows the off-set to be bent in on the piece without separating the rudder entirely.

The upper wing requires an actual accuracy correction; if you look up at the 'kit' photo heading this, you will see it was moulded with some dihedral, which it ought not to have. The upper wing in this kit is made with a very hard and brittle, almost translucent plastic that will not bend, but happily breaks (there is a reason the other Demon kits I bought were built first) at small provocation. I simply scored at the center, cracked the wing there, and held it with CA gel. This gave a 'tenting' at the center, which I filled in at the bottom with CA gel, and sanded down from the top. The fuel tanks are rectangles of 'furnace foil', as are the Handley-Page slots. Hand-holds were put in at the trailing edges of the center section, and pieces of thin sheet cut and shaped for the slat actuators.

When I get back to the bench in a couple of days, the fabric areas will be primed and painted, and the nose of the model covered in aluminum foil (kitchen foil boiled a bit with water eggshells have been boiled in, and treated with a contact adhesive). With a smile from the modelling gods, even attachment of the upper wing and rigging is possible. Wife has said she will set up decals for the serials numbers, which will be a big help.

Thank you for your kind comments, Gentlemen.

Here is the state of play at present; a little behind where I had hoped to be, but still on track for completion before the deadline....

Primer coat showed up a few areas that needed tending, and putting them right took some time.

The second picture shows the 'wedge' under the tail-plane and the exposed bit of jack-rod.

Am about half-way through the process of putting on the aluminum finish. I use an ordinary craft acrylic silver, with a healthy dollop of white added, and the mix cut heavily with Future. First covering coat gets sanded thoroughly with a polishing pad (3000 grit) after it has had several days to dry; the picture above was taken when the paint had only just dried to touch. One or two more thin coats then go over that, with a final session following with the pad.

Excellent work, OM! I don't know how I missed this one, being the Hart Family aficionado that I am. It almost tempts me to get back to my long-stalled Hartbees conversion/rebuild of my old Airfix Demon model.

Regards,

Jason

Just a quick note to say this has not lapsed, but I have not been able to get any pictures, and will not be able to till after Christmas. However, painting is done, foil applied to nose, and all decals are on. I do have every expectation of getting this completed before the closing date.

Thank you, Gentlemen. And I do consider myself very lucky indeed....

A bit of progress to report on this....

Exhausts are in, and radiator and vertical tail surface are on.

Though it may not look like it, I remain pretty sure I will have this in hand by the deadline. Only a few small bits of detailing, including wind-screen, and the undercarriage, remains to be completed before the upper wing goes on and I set to rigging.
