I went to the customers house to view an existing screen because they wanted this new design based on that but with modifications. Plus had a look at where he'd be mounting it and took measurements for where the mounting tabs would need to be welded on.
Cad time involved manual trace of a maple leaf photo.
Surprisingly it was about a 2 hour round trip to pick up a sheet of steel and go to another supplier to get angle iron. Delivery is starting to look more interesting.
A few of the leaf cutouts were welded on top (dark brown in the picture). I did this by cutting holes in the screen where the leaves would be, clamped the leaves in position on the front side, then went round the back and welded through the hole. Did this one by one for thirteen top leaf pieces.
The border is 40mm angle iron. Cut 45 degree corners, drilled big holes along the length where it lies on the back of the screen, and welded through these holes.
Finally cut 4 mounting tabs and made "keyholes" in them for blind hanging on screws in the wall.
3mm corten type steel, dimensions 2440 x 1100mm
Delivered to the customer myself, about a 2 hour round trip once I've unloaded, helped him carry it in, and done the usual 20 mins yakking while I'm there
Took a lot longer than I expected but I've learnt a few things and I know next time I'll be faster. One thing I've noticed immediately is try and cut with dross free parameters or at least get low speed dross parameters so it come of very easily. The dross which could be mistaken for weld bead is tedious to knock off.
I won't say how long cad time plus manufacturing time was because that's irrelevant being a beginner thus slower. I can't charge for my lack of speed.
