I always try to find a "better way" when taking on a new task. Sometimes because I've never done it before and need to "teach" myself. This always requires testing "off model" to prevent doing any damage.
When I drill holes of any diameter larger than 2-3mm, I tape over where I'm going to drill and place the hole target on the tape. This prevents the wood splintering around the edge of the hole. As someone noted, this may not be needed with drilling holes for masts as the mast collars can/may cover your rough edges.
With that said, the largest holes requiring drilling present the biggest challenge ,for me). I find it even more difficult and frustrating to attempt to manufacture a large hole with hand tools, rasps, files, etc. I just don't have that talent. I have found that step drill bits work well for me on larger holes. I find the center. Make a small indent with a punch. Drill a pilot hole, maybe 1-3mm, then drill down to the "step" on the bit that closely matches,
but is smaller, than the diameter I need.
It may not be what others choose to do, but I thought I would share what has worked for me. I try to find processes that I can use an every project successfully. For me it's about feeling confident in the method and allows me to progress. I find that as modelers, we all stall in our progress when we are not sure of what to do next. Finding methods we prove work for us allow us to move forward with confidence, that is until the next problem, requiring a solution presents itself.
Here is the set I use.
Good luck!
