OK.
I've done a bit more cutting.
I have finished all the "rough" cutting of the front, back and internal panels.
I have also cut the sides.
A couple of tricks I've picked up already which might help first timers, like myself.
1. If using a circular saw, you
MUST use a saw guide (or something similar).
I've previous built projects without a saw guide, and honestly, you are wasting your time without a saw guide. Simple to build and use.
2. When measuring and marking, use a fine tipped pen. I'm using a pen called a "Sharpie Pen". The very fine tip makes it easy to mark the timber on the exact spot against the tape/ruler. And then the pen also leaves a very fine line when drawing your cut line. I am also using a large square when marking a line to cut across a sheet (after I have ripped one side which becomes my reference straight edge).
3. When drawing a line against a straight edge, hold the pen at the same angle for the full length. This ensures that your line is truly following the straight edge.
4. When marking the width of a panel before cutting, mark in at least three spots (each end and in the middle). When lining up your saw guide with the marks, you can easily tell if one of the measurements is incorrect. I've mentioned this tip because it saved me from making an incorrect cut on one of the sides. Also, remember which side of the saw guide is the panel you're making. The saw guide should be sitting/clamped to the panel with the saw guide covering half the width of your marked line or spots.
5. And the tips that have been mentioned many times :- take your time, measure at least twice, and when you have the saw in your hand, hesitate and re-think everything before actually cutting.
, but throughout this thread I will exclusively be talking in millimetres except to tell you that my T39s will be 27" wide internally. That's 686mm in real terms.
). I used a square when measuring the intermediate measurements to make sure all my measurements were true.
