Sam you are one sharp cookie. The pieces in the forge are from the project right after the grate, which is already shipped away with out a picture, king size bed. I just happend to have the camera out in the shop and snapped both pictures.
The process, is as you say. Draw the whole thing out on the table, and make a jig to bend the parts on. Heat the parts, and shape them to match. However, you can buy parts that are factory bent, and then re-shape them to fit what you are doing. Which is what I did here.
There are several levels of blacksmithing, (forgery). The easy way is buying forged parts and welding them together to make what you want. The least work, and the cheapest.
2nd, is buying parts and shaping them, re heating them in the forge, and getting a custom fit, that looks right. Not the cheapest, not the best. 3rd, starting from scratch. Much more work, and lots more expense to the end user. It also has the best look, and you can see the details much better. That is the readers digest version. There is much more to it.
It all comes down to what the customer wants to spend.
I like playing the field. I usually don't get tired of projects as long as there is something different going on every few days. For alot of the art work stuff, I have to be "in the mood". At least I feel like I do better when my heart is in it. And in short, it all pays the bills. I just have more fun with some of it more than others, but it is all fun.
