Step 11The stubby version: finishing touches
I added some screws through the body abutting right up to the element assembly, to locate it in place centrally in the barrel, and also to stop the plastic film canister slipping when being gripped. Some spiral cable wrap covered the joins in the mains cables.
The device is now usable: it can be used entirely one-handedly, with middle finger and thumb gripping the barrel (which doesn't get very hot), and index finger keeping a light on the end of the glue stick to help feed it through. It pumps out a narrower stream of glue than the standard glue gun, and feels a lot more like a soldering iron to use.
But there's still a lot that could be improved. It would be great to make a truly pen-like device, smaller diameter, with an even smaller nozzle for really precise applications. The original blue plastic casing from the Bostik glue gun may be useful here, cut down, fitted back around the element to give a neat casing. Oh, and that metal nozzle (and the screws) need to be earthed, or covered with an electrical insulator.
Overall this is a pretty vague, haphazard project, but I think it's produced a reasonably useful device.
