ANSI Limits and Fits Calculator - Amesweb
ANSI limits and fits calculator works in line with ANSI B4.1 standard which is based on inch units. According to nominal size and fit type selection among running and sliding [RC], locational clearance [LC], locational transition [LT], locational interference [LN], force and shrink [FN] fits, size limits for hole/shaft are calculated with schematic representation of the fit.

How to Use a Lathe | The Hobby-MachinistIf center holes must be located and drilled into the end of a workpiece for turning lay out and center-punch the workpiece using other methods. Some suggested methods are to use a bell-type center punch between centers and this cannot be accomplished on the lathe, (Figure 7-32), use hermaphrodite calipers to scribe intersecting arcs, use the punching square holes into 1inch pipe practical machinist Milling How to drill holes in 3/8" thick steel plates? - Home punching square holes into 1inch pipe practical machinist MillingUnless you don't care where your hole ends up, center punching alone instead of drilling a pilot hole is a losing proposition: too big a final diameter against too much material thickness. If a center drill is not in the mix, 3/32 to 1/8" is near ideal for doing pilot holes. A carbide drill bit is the real deal, but usually not cheap--check eBay.
