I have a Whitlox forge, built from their kit. For smallish items, it will heat to forging temperature in 10-15 minutes using bagged hardwood charcoal. I'm definitely a beginner, and my one attempt at welding did not succeed, but it certainly gets hot enough. That said, I suspect Damascus would require quite a bit of skill but would be possible.
Charcoal consumption can be pretty high, but is definitely easier to manage than hardwood and doesn't require quite as high a fire.
Good luck with your plan!
