Hmphhh! Seems nobody wanted my handrail routine. Oh well, as I said I'm going to get fun out of it.
Now for the next pile of frustration: A lisp set that does wooden joinery,ie windows (or called millwork in the USA). A friend of mine recently bought an English program that costs up joinery, so maybe I'll add to my drawing part to create a saleable item. I think I'm done now with giving some things away for free.
Progress has been slow-it is now at the stage shown in the pic.
I'm realising in my travels that there are some drawings done by architects of joinery, but most of these only have a passing nod at doing things to scale. It seems nowhere is there an "engineering" type of scale drawing exactly how joinery is constructed.
