It's beefy, the base is weighted/heavy and I've held up many large boards. Might not hold really wide boards but no reason you can't hold it in the narrow position. It can be set to straight up/down or any angle you want. Also, it can rotate easily (simply depress and rotate to next detent). The round base in your image can be bolted down to the table/workbench. Mine is screwed onto a metal circular platter with compartments for holding parts (caps?) thereby giving it additional weight and spreading the footprint. Ii also have the one with the legs and it might look small in the picture but it's not. I think it's footprint is about a foot square. Be advised, the panavise system is not cheap so be prepared to shell out some bucks (more than you paid for the caps) if you want to go that route. For a single job, maybe not worth it. However, if you plan to do more in the future, it's a good investment. I build all my M70 lamp modules on those as I can hold multiple boards (in a row) while I do the assembly. Oh yeah, the panavise system is a modular system starting with the base. From there, any number of accessories such as vises, clamps, etc can be used on it. The PCB holder is just another accessory to build onto the panavise.
