Well I'm a Fitter/Turner/Toolmaker, Plant mechanic, but I spent the last 45 years in the building trade doing earthworks commercial and domestic.
Made 15000 bricks for my new house and fully conversent with concrete, tiling, carpentry, engineering and bricklaying.
I invented a product 20 years ago and now spend my complete retirement manufacturing it!!! along with many other products.
I just wish I had gone down this road 45 years ago LOL(lookout ARB)
I think that once you learn a trade, you eventually come back to it if you see an opening.
I also have a fantastic Wife who does all the books and posting.
Well that's my story and I'm stick'n to it.
Cheers, the ferret.
