Firstly, Bill, would love to know how your 1/48th "Merlin's Magic" turned out, as it started really well. Did you ever post finished pictures? Terry, your comments just confirm how much conflicting opinion there is on these matters. Who do you trust? Well, unless I hear differently, I'm putting my trust in the opinions of the members of this Forum.
An update of where I am at the moment on the build, just to pretend I haven't been slacking, totally.
Picture 1. After an initial bout of sanding, I sprayed a coat of primer on the control surfaces, to show up any defects and to see if more sanding is required. These will get another coat when these adjustments are made. The flap extensions were added, first pinned with superglue, then 'welded' to the flaps with liquid poly on the undersides. These need to be trimmed to fit properly in a deployed position and then should slide under the tailing edges, with a curved surface, after a bit more sanding and a coat of primer to check joins, etc.
Picture 2. Shows the stages of scratch-building the telescope and head armour. Inset 1. shows the telescope comprising three sections. From top to bottom, a piece of sprue, drilled at the back, as the eyepiece. The centre piece is part of an old 1/72 rotor hub assembly, from the parts box, which just mirrors the shape of the actual 'scope, nicely. The front piece is rolled plastic card, secured with liquid poly, trimmed and sanded to get rid of the step-join. Main photo; the telescope, from the front, in scale to the canopy, after a coat of primer and sanding. The arrowed part will, hopefully be adapted to represent the mount for the 'scope, from the canopy frame. The pilot's armour/headrest, made from three pieces of plastic card - the top piece being thinnest - still separate at this stage. The centre canopy is the part supplied with the kit, for scale, as I haven't got around to slicing the replacement vac-form canopy yet (slacking again!). Inset 3. is the padded headrest completed. The top two pieces were cemented together and covered with two layers of builder's textured masking tape, enough to give a padded effect. This was carefully pressed into the stepped contour with the back of a scalpel blade. I was then able to indent the edge pattern into the soft tape. The three circular indents in the pad were achieved with the rounded point of a pencil. I then gave it a coat of brown/red enamel and dry brushed with burnt umber, with the edges highlighted in lighter brown.
Picture 3. I decided to add blast tubes to the cannon openings (Why, you may well ask!). The trouble with this, is that a blast tube wide enough to accommodate the full barrel wouldn't allow the wings to close, hence the truncated version you see here. This was fashioned from the plastic tube of a cotton bud, which is just the right diameter to allow the wing to close. A coat of RLM 02, and nobody will be the wiser.
Picture 4. is the fuselage finally buttoned up. The adjustments, I made earlier to the trim wheels etc., worked and it slotted together without any difficulty. From back to front, the (oil?) hole in the fuselage has been filled and will be indented in the centre. The sloping back plate has been fitted and any gaps filled and sanded, awaiting painting. the port side sill has been added. the saddle cowling is now (loose) in its final position. Unless I file the gun tops to nothing, you can see where shimming is required. The cowling top still requires filling and sanding.
So that's where I am to date. I'm now trying to decide the best sequence to progress the rest of the build. I think finish the wing assemblies first, then attach them and the tail planes to the fuselage, ready for painting. Then, I think, work on the canopy, masking for painting internally and externally and when painted add the telescope, making sure it doesn't interfere with the Revi sight, when that's installed. Then on to the prop assembly and lastly, undercarriage and all small external details.
I'll keep you updated as it progresses.
