Hi, I'm Jelly or Joshua [Kelly], if you prefer.
I'm an Industrial Chemist working in Hazardous Waste Management, so if you ever want guidance on what chemicals do, I'm likely to have a cogent answer for you... Or possibly quite a complex non-comittal answer, it depends how much I know about your intended purpose for them really.
I used to work in a sawmill and in a joiners shop before I went to university, as a result I know a reasonable amount about woodwork, wood machining, setting/fettling machines and sharpening saw blades. Off the back of that I also have a fairly compete set of joinery tools, and if you need a specific tool for a job or are unsure what tool might be best for a task I'm happy to lend you mine to try, or even show you how to use the right tool.
I'm slowly becoming versed in a variety of machining operations, heat treatment, metal punching and pattern-making. That all came out of a plan to make my own saw blades using a fly-press, which snowballed.
