<html> Hi Gordon,                   A trick to boring those holes, that are already there.  Take a piece of 1" thick piece of scrap board.  Drill a hole right through it with a Forsner or Spur bit. Centre and  tack the board over the hole with a couple of nails. Now you have a perfect guide for the Forsner bit to redrill the old hole.  This make the drill easy and safe to control. Save the template for the next job, you will have the job done in no time.  We have a selection of templates in the shop, hanging on a nail waiting for use. <G> Regards Roger At 11:52 AM 10/6/02 -0700, gordon stelter wrote: <blockquote type=cite class=cite cite>Amen to this! I used a LOT of those double wheel, rubber, ball bearing casters on uprights. But I used a FAT masonry bit (BFMB?) instead of a speedbore, as I think its easier to control while drilling in an already present hole ( the old caster socket ).  I sure hope Schaff keeps selling these!!!     Thump</blockquote> </html>
