And now on to the fiddly bits - the Rocket Projectiles and rails!
The following is also intended as a guide for Daniel (109 Roaming), who also has a set of these RP's, and will be converting the old Revell kit to, so pleas bear with me..
The Typhoon was fitted to carry either bombs, or RP's, but not both. The model will be a rocket-carrying Typhoon, with a change of identity from the thread title, and will be the replacement 'mount' of Sqn. Ldr. Mc.Nair, of 247 Squadron, RAF, in late July,1944, coded ZY-G, serial number MN928.
The RP's were normally the 3 inch, 60 pound SAP/HE, although 25lb armour piercing missiles were also available, used mainly for anti-shipping strikes.
The RP's used in this conversion are the very nice resin set from Model Design Consultants, with the later launch rails and the 60lb warhead.
PIC 1. Shows the parts for one RP and rail set laid out, with the rail at the top, and below it the warhead and rocket motor body, with the electrical firing 'pigtail' at right, and below, the P.E. set for the fins and mounts.
The first job is to prepare each rocket-motor body, by cleaning-up any moulding residue or flash, and remove the moulding strip from the top of each launch rail, and the moulding plug from each warhead.
PIC 2. This is the forward end of the RP body, where the warhead attaches. The extreme end needs to be carefully removed with a razor saw, and the remaining 'stub' very gently sanded to remove any excess resin.
PIC 3. The end of the casting removed, showing where the warhead slides on.
PIC 4. The tail-end of the RP body, with the grooves for the brass fins. The raised lines with small 'studs' are where the brass reinforcing strips attach. Note that the 'saddles', the brackets which mount the RP to the rail, have a groove on one end, and this is the end which attaches to the rail. It may be necessary to clean-out this groove slightly, but be careful - it's very easy to cut-in too far!!
PIC 5. I drilled the tail-end of each RP body, in order to insert a piece of wire later, to facilitate painting. This is optional, and it might be best not to bother, as the resin can easily split, as shown later. The completed missiles can be clamped by one fin whilst painting, and then this fin painted later.
PIC 6. The casting plug has been carefully sawn from the warhead, the area gently sanded to clean it up, and then the part pushed onto the RP body, with a small spot of 'Superglue' on the end of the latter. NOTE: the notches on either side of the warhead nose represent the notches on the real item, where a spanner or 'key' would fit, to tighten the warhead after it had been fully screwed home on the body. The warhead has also been moulded with a textured finish, duplicating the rough-cast appearance of the real thing.
PIC 7. These are some of the brass photo-etched parts. At the top, the small strips with the 'pimpled' surface are the reinforcing strips for each fin, which fit one either side. The 'pimples' are supposed to locate into tiny dimples on the ridges along the end of the body - yeah, right!
The fins have a small, triangular 'tab' on one edge, below the round hole, and this fits into a tiny hole between the ribs on each RP body. I found that the 'tab' needed cutting down slightly to allow the fin to 'seat' properly.
PIC 8. One fin in place, with the reinforcing strips either side, attached with small spots of 'Superglue'. For me, this was a fiddly, tiresome job, but for people with normal dexterity, it shouldn't pose any major problem. All that's required is patience and a relatively steady hand. But be warned, there are 32 sets of these to fit!!
Note the very small piece missing from the end of the 'exhaust' outlet. This is where the resin split whilst drilling.
That's it so far. Once each RP has been fully assembled, they'll then be painted, and fitted to the rails, which will also have been painted. The vinyl 'pigtails' will be fitted into the rear of each rocket-motor, and painted in situ, but left hanging, after each rocket and rail has been fitted, as a complete unit, to the underside of the wings. (NOTE: the 'pigtails' were only connected to the wing sockets immediately before start-up and take off, in case of any electrical 'short' or other malfunction causing accidental launch.)
Thanks again for your interest, and I'll post another update soon - or when I recover from handling tiny PE parts!!!
