Looks like Im gonna have to work on my front arches to get these 18s to turn full lock. Ive got two plans in mind.
Plan A: trim the bit underneath the lip of the arch out to a knife-edge and then flare them out as well so they dont catch.
Plan B: cut the arches higher into the side of the wing (the outer bit you can see) and try to do it neat so you dont notice that its been done, itll just look like a bigger arch (in height not width)
Ive got a feeling Im gonna badly mess it up either way. Any suggestions or ideas? Im more inclined to try flaring the arches rather than cutting them bigger, but will a hot air gun (wallpaper stripper) provide enough heat to bend them?
