By jove chaps, I think I've done it !
After about another four hours work of sanding, test fitting, filing and sanding, I was finally satisfied enough to fit the engine in place, using superglue at the front lower part, and cement at the rear of the engine bearers. It's now in position, and although not 100% perfectly aligned, it's good enough. Of course, it'll now need some repair work to the damaged wiring etc, and re-touching here and there, as well as re-fitting some of the parts I had to remove.
Once it had set, the cowlings were test-fitted yet again, and some more filing and sanding done in various places to get everything to line up properly. The final bits, including filling the small gap in the lower cowling, and adding thin 'shims' where needed, will be done later, after the main construction of the rest of the airframe is completed.
Again, please bear with me, as most of the following is for the benefit of Lewis, who has the same kit to build at some stage. Also, remember that all of this is so that the cowlings can be removed and replaced at will, but still look right when in place.
PIC 1. The engine finally glued in place, and awaiting repair and re-painting.
PIC 2. To avoid interference from the guns, gun mounts and the front of the engine block, the inside of the main cowling was filed down around the front, tops and sides of the gun troughs. They're thick here, so there's little chance of filing all the way through ! The area inside, where the 'bumps' over the gun mounting arms are on the outside, was also filed, and it all needs sanding smooth in this pic.
PIC 3. The same exercise inside the saddle cowling, virtually obliterating the mouldings around the locating pins, and thinning down the internal 'lumps' where the small, rear vents are on the outside.
PIC 4.The rear edge of the glycol tank was sanded, but retaining the basic profile, and this will be re-painted.
PIC 5. The extreme lower front end of the starboard nose section was gently sanded to conform with the line of the upper cowling. All of this sanding work has yet to be polished.
PIC 6. The lower front edge of the port side of the upper cowling was sanded, to conform to the line of the lower fuselage, and the inside of the front rim sanded also. The small access hatch and the cowling latch detail, both of which were rather 'heavy', will be re-scribed later.
PIC 7. With all this done, both cowling sections were placed into position, and they now fit ! The main cowling is too light to sit all the way down, although the gap looks bigger than it actually is in this photo. Rather than mess about further, this gap, and the bigger horizontal gaps on the saddle cowling, will be 'shimmed' with thin strips of plastic, sanded to match the surroundings, and blended in. Notice that the characteristic lip, and narrow gap, between the top of the main cowling and the saddle cowling is now like the real aircraft.
PIC 8. What the underside of the nose now looks like. This is a relatively minor job, and will be attended to once the oil cooler fairing has been fitted and the sink marks filled. The oil cooler itself normally fits onto the bottom of the supercharger intercooler pipes, now removed, so a small bracket will be made and fitted, and the oil cooler attached to this.
Note that theb prop shaft suffered in all the test-fitting! This will be corrected, somehow, later.
With this hurdle out of the way, the construction steps continue, not quite in sequence as per the instructions, and the radiators and wings are under construction.
PIC 9 shows one of the radiators, with the matrix in place in the 'bath', and the support stay at the front intake thinned down.Also seen here is the deflector fairing set onto the inside of the wing. I was going to use some scrap etched grille here, but I don't think there's much advantage, so it'll probably be utilised on the rather ropey Hasegawa radiators, which I'll be replacing with home- moulded items once that build gets underway.
That's it for now, and I hope to make some real progress, now that the engine fitting has been taken care of.
Thanks again for your interest and compliments.
