I’ve got to organise a custom tool, to counterhold a crankshaft.
It’s basically a ring of steel 8-10mm thick welded to a handle around 25mm wide by the same thickness by 400mm long. The ring part will have multiple 8mm fixing holes drilled on a 49mm PCD. It will be about 70mm OD and needs a centering bore of 35mm. Cutting the handle, ring OD and drilling the 8mm holes present no issues. I’m just wondering about real world approaches to drilling the centre hole, Google is one thing but I’m interested to hear from people who’ve sawn holes like that in basic garage workshop situations, with commonplace tooling. As in, will a bimetal holesaw do the job if used slowly and gently? |
