I made a vacuum pump from a compressor a couple of years ago, when I was swamped with repair work, especially bride reglues. It worked great for that period, re-gluing many bridges, including a Paul Fischer, Paulino Bernabe, among very many others. Just 2 weeks ago, it failed! So it's back-up plan, to the bridge clamps I go.
Left her clamped up overnight and chiselled clean the glue squeeze out.
