Working surface of my sweep drawer & work bench is 29 1/2 in from floor. I find that a good height for my comfort.
I work with the hand piece there, in front of the vacuum port for polishing.
When grinding ( no vacuum ) I add the deflector, the ground metal falls in the sweep drawer.
I keep the pickle pot, water for quenching and liver of silver near to the soldering station, the exhaust fan port takes all the fumes outside.
It is also sheltered from light, so I can observe metal color when using torch.
Heavy work I do on the side bench, it has solid, legs & top. With swivel stool it is convent to go between work areas.
Hope that I am giving good explanation. Will try to add pictures to this posting, for further clarity.
If the pictures do not go thru, you can send me your email I will send them direct.
