Default Re: Simple method to mark calibration and functions externally on a case?

Al,

I have attached some images of a prototype device I've designed that I'm still writing an article about, I will post that article when its finished. But it shows the type of Brother label tape I used on it.

The Box is a die cast aluminium type (like an Eddystone box). I treated it with Bondrite which is an aviation etch prime solution similar to Alodine, then painted with VHT spray paint and baked it in the wife's oven. The pictures give an indication of what the clear label tape is like. This tape is ok for a limited amount of writing, but it is better to do a computer printout for something like an entire dial scale.

Obviously a superior result in this case would be obtained from having the box both professionally powder coated and then screen printed, but then it has to be passed off to other parties and it is more time consuming to do it.

Hugo.
