Mmmmm... it sounds like the ratio may have been incorrect. If it isn't solid after 24hours, it most likely wont ever go off.

We will be using epi-glue for the workshop, so we can look at that.

Getting an accurate measure by vol is near impossible when your only trying to mix up 15ml of that stuff. They don't list a weight mix ratio.

Let's have a look on the day as we will be mixing up a few batches. Fee free to bring your glue too so we can see if there is any consistency differences

Incorrect mix ratio is exacerbated when mixing small quantities.
Disposable plastic syringes are available in small sizes.
There should be data sheets which would show the density, so you can calculate the corresponding weights. Note: temperature will affect this.

Any chance of running a workshop on electronics?

I can deal with the gizmos if all I have to do is get them out of the box and turn them on, but I struggle with some of the terminology, and certainly when it comes to reprogramming etc, even simple things like getting them to communicate with my computer seem to be impossible.

I'm sure I'm not alone.

Anything is possible. We will prob have to do a questionnaire though to see what electronics people want to know about and any specific questions. Please shoot us an email with a couple of specific questions which will help work out how to best attack it.

Another workshop will most likely be on 'Open Rocket' if that is of any interest?
