Geez..., mate what a bugger of a thing to happen...!:frown:
I'm glad that the damage was contained within the work-shop/shed and not in the house and that you weren't in it when it burnt. Like my previous fellow IAP members stated, is good news that no one got physically hurt in the process and yes, a lot of that stuff (equipment) can be replaced, a lot easier if you had insurance but the vast majority of us don't have any, most of our work-shops or sheds would be insurable anyway, the amount of stuff and how we keep things (volatile materials) together, no insurance would even touch or consider...!
Anyway, from the devastation in those pics, I reckon some stuff will be able to be salvaged if no insurance is involved, and from the "melting" condition I see on some gear, the heat was considerable in some areas so, if melted the plastics that easy, I'm pretty sure that all you wood stock (blanks) are truly gone so, I may not be able to help you in other ways but I can certainly help by sending you a box full of blanks so, all I need is your postal address details and I'm on to it...! (Send me your details by PM, only...!)
Good luck mate...!
Cheers
