I do a lot of spindle-turning at the lathe, and find myself turning sections and details to the same common diameters time and again. Rather than constantly resetting my calipers, I devised a gauge for these diameters, making it from plastic laminate, which is thin enough to slip into parted areas and in between beads.
I find that when I need to neatly apply a thin glue or solvent, a plastic pipette is just the tool for the job. These squeezable lab dispensers, with their tiny tips, work great for targeted applications of thin or medium viscosity cyanoacrylate (CA) glue (“super glue”) when filling cracks or making repairs.
It often helps to raise a workpiece up off the bench, especially when you need clamp access underneath. Although you can sometimes just use thick boards as risers, I’ve found that I-beams work much better because you can clamp them to the benchtop, then secure the workpiece to the top beam flange.
