Waldo, I want to drill a hole in a plane through the covering and ply to mount something but I don't want to tear the covering.
I use a soldering iron to open the covering over existing holes. But I want to drill holes to mount my own stuff, like an ignition LED, and not tear the covering in the process. I have tried step drills, progressively larger bits, and spade type bits. Sometimes it works and sometimes it doesn't. Need something like a sharpened piece of tubing to precut the covering before drilling. A small hole saw that does not tear the covering.
wayne all the ideas that have been listed all work great I guess it really depends on what your situation is, in the case you described the tape idea is great, I usually use the monocote iron and heat the covering so its hot and sticky then poke a hole with the point of my nice sharp xacto blade where I'm going to dril with a very small bit once you heat the area the covering should be tacky enough to drill away without it tearing but the tape is a pretty good way to go for security. On holes I just use a new blade in my xacto and on hard surfaces I will use a soldering iron sometimes, but I pretty much just use an xacto and straight edge with a brand new blade on any slicing or cutting on the model. with a new blade and a slight angle it ususally cuts like butter, I mostly cut on the stab to take away the covering to epoxy on the fin so even if I feel I sliced into the wood a touch, glue is going right on it anyway. I usually have no problem drilling holes in covering as long as you poke a hole first I can't say I ever have torn the covering drilling.
Brathanke glad your getting closer on the slick
That was a great airshow video
Well the tensioner on my van blew the bearings froze up and snapped my serpintine belt while on the highway
lol luckily I was able to get it off the highway and to a parking lot a friend of mine just happened to be behind me and was able to give me a lift home after we tried to change the belt and realized the tensioner was shot, so my good cuz picked me up the following morning and 3 hours later and $70 I was running again, got out of that one pretty cheaply phewwww
