I, or rather we, tried our hand at cutting the polystyrene, which really is not bad once you get the hang of it. We started on the rudder as this is the smallest and simplest of cuts in my opinion.
BUT here is my advice...
* * N O T E * *
Whisper can cut your polystyrene and I would suggest one makes use of this option for the following reasons;
- It is simpler
- Time saver
- Cuts are perfect (I think a CNC is utilised for this)
- Zero waste because they get it right first time
- You need good help to cut with you. Not a one man task!!
If you go at it yourself, no problem, it is actually a lot of fun. My son helped me cut and I found him the best talent in the family. My wife and I are in too much of a hurry and get it wrong, while Emil (my son) get it just right. Our cuts are almost perfect, but it took a bit of getting the hang of it. My advice is...
- Cut slowly, don't force the wire to move, just let it go at the pace it is happy to
- Clearly mark progress positions on all the templates (pro-rata to the size of each) and discuss the cut so both parties KNOW exactly how the cut will progress
- Talk and indicate progress during the cut continuously and stay synchronised as much as possible, especially around any corner or curve
- Do the complete cut in one go, DO NOT STOP as you'll see this on the cut when you're done
- Consider a practise run before you do the actual first cut (have spare foam for this!!)
- CHECK your template alignment before each cut, as you cannot undo a cut
It is a lot of fun and great bonding this to do with your son, if you get it right
NOTE that you will likely make mistakes and this is human, so don't be too hard on your cutting partner, as this can obviously ruin a friendship
As mentioned, check your template alignment! I got one cut inverse
The middle template actually does need to be marked with progress indicators on both sides
To check the blocks for right angles, I used the laser level, which I found a hundred and one uses for!!
