So work doth begin. 99% of the flash is gone as have all the gates. Has taken a fair bit of scraping and cleaning. There are a few places where the resin has bubbles or poured thin that need filling or reinforcing. I need to partially rebuild one of the week where the resin is pretty soft. Still needs a couple of once overs to make sure I haven't missed anything before a nice soak in some washing up liquid.
Fair bit of work required but a start has been made which is the important bit!
