To elaborate on the question, I have a metre long steel tube, an angle block, and a press drill.Some holes need to be made at specific intervals, and some are at right angles to the others.Does anyone have any tips on how to get perfect drills along two perpendicularly intersecting planes?Also another issue that I envision will be a problem is the straightness of the drill, because the angle block is much shorter compared to the tubes, and my table is not perfectly flat so the tube might not be sitting on an flat plane?Appreciate anybody with some tips to reduce the likelihood or me messing this up. The workshops are only willing to do the job if they get to rip me off.Well, to be fair, the quote they gave me was for simply 'drilling holes on a tube'. I hadn't even gone into detail at that point. Only upon considering I might resolve to doing it myself did I elaborate in the above post of what the task involved. But your point is understood, maybe I should have kept that last part to myself! via /r/DIY https://ift.tt/2rj3EZz
