The instructions recommend fitting components from one bag at a time. This way similar components are unlikely to be mixed up, causing problems later on. This will actually be more important with the latter bags, where components like capacitors which can have obscure markings, unlike the resistors from the first bag.

Components were fitted in the order detailed in the instructions. They were ticked off the parts list and highlighted on the overlay as the were fitted.
The resistors supplied with the kit are very small, low power devices. It was noted that the leads had to be bent almost at the resistor body to allow them to be fitted to the PCB. I prefer to allow a slightly bigger gap between the bend and the resistor. This is so there is less chance of cracking the body of the resistor, however no problems were noted during fitting.
The board was found to be of very good quality, and easy to produce good soldered joints.
Build time for Bag 1 was approximately 4 hours.

Before the next stage is undertaken, the solder side of the board will be given a through check under good (daylight) for bad joints etc using a magnifying glass. This will be repeated between stages, and therefore should eliminate problems due to soldering.
