I first make the marks with a sharp punch, then use a centre drill and finally drill (right through or not, depending on the piano) with a special (German) wrestplank drill which has a more acute point than the jobber's drill and a faster spiral.  If drilling a pilot hole right through would make the result more precise, I'd do it, but I don't see that it would.  However I would never consider using the wrestplank drill without first using the centre drill.</div> <div><br></div> <div align="center"><img src="cid:p06240802c27d047a4ad8@[10.0.0.1].1.0"></div> <x-sigsep><pre>-- </pre></x-sigsep> <div >____________________________________________________________________<span ></span>__<br> Delacour Pianos  *  34 Station Road  *  Poole  *  Dorset  *  BH14 8UD<br> Phone:  01202 731031  *  Mobile: 07801 310 689  *  Fax: 0870 705 3241 ______________________________________________________________________</div > </body> </html>
