P47 D Thunderbolt Construction 1/8th Scale
Hi Gang,
Here we go, the continuing saga of the dreded under carriage doors. Well as you can see the final result was a good one. However, for a total beginner it was a nightmare. Many hours of head scratching and trial and error and i finally came up trumps.
The first part was easy, cut the doors into the 4 sections that are required. This was a walk in the park with the old badnsaw. Now came the hard bit. The Thunderbolt has a section that fixes solid to the wheel, not much room was available for fixing. A bracket was made out of brass shim stock to form a clamp around the strut and a little of 5 min appoxy finished the job. Next came the problem of travel. Because the section on the wheel is fixed and the strut is longer than the next section of door allowance has to be made for the door to pass over the whell door as the retracts opperate, some sort of device has to be made to lift the door as it rises, you can see a D clamp on the strut with a bent wire brace, this hinges as the strut lifts and cause the door to raise off the strut and provide the clearance for travel. I did intend to use a ball joint for this but as this model does not allow for doors, clearance was minimal and provided no room for these once the doors are closed. The next problem due to this non existant space factor was how to hinge the next section of the door at the retract unit. This was done by means of a sort of fibre material that you can buy for this exact job, fortunatly some came with the kit and was meant to be used for the ailerons and rudder hinges, where instead i used proper hinges. Glueing this to the fibre glass doors proved tricky and i wasnt 100% happy just incase the ripped of in mid flight, to overcome this i made some very tiny plates, again from shim stock and fixed them through the hinge material into the door with tiny CSK screws.
Once satisfied with the operation the last section of door was fitted, these have a bent peice of wire firbe glassed to the inside of the door. This comes into contact with the wheel as it is lifted and acts as a closing mechanism for this section.
Now the struts. As you can see in the first stages they are naked and i thought that i should add some realism, so i cut a slice out of some tube and clipped it round the struts a couple of peices are added in areas to form a collar look, a couple of trays are added and then some brake tubes. The final touch is to coat it all in some fuel proof resin ( matt ) this gives it a little bit of a weathered look also.
Stay tuned for some more scale building folks.
