Hi Guys
Once again I need some assistance.
For the Cave Tonitrum I'm building the Academy 1/48th Bubble top but I've hit a snag
there are two seams that I'm having trouble figuring out, how to eliminate them.
The first one is in the wheel well as the wing to fuselage seam runs 90 degrees to some ribbing.
The second is just in front of the ventral exhaust it is a small box like area that I would have difficulty in getting a file or sandpaper into.

Any ideas please.

Thanks

Chris

My thought on the wheel well problem - get a small jewelers file with a square tapered end. Very gently rub out the seam in really small increments. Use the shape of the file to preserve the angles where the ribbing meets the 'skin' of the plane. I would file at 80-90 degrees from the seam line (Parallel to the ribbing).

The second one ? hmm, if you can't get a file in -then make one. Get a paperclip and grind it down to a scraper shape. The gently scape the seam away.

Both techniques require very patient gentle scraping.

For the second one you could either use normal filler and when dry wipe the access away with a cotton bud dipped in nail varnish remover, or another way to deal with this is to cut a piece of very thin plastic card to shape and cover over the area.

Another way is to fill the seam as normal, then instead of sanding the area, use the acetone fingernail polish remover to removel the excess filler. This can be easily done with an ear swab. For better results start removing the excess filler just as it begins to dry. It'll make your job a bit easier and won't remove surrounding detail.
