Drill Bit Question: Background: Yesterday I was trying to repair an Everett console that had a separation crack between the last lamination of the pinblock and the back beam. I guess it's glue joint failure and a downward warping of the wood from the downward pull of the tuning pins. I made plans to install 3 bolts 3/8" x 5"L after applying CA down in the crack. However, drilling through the plate took about 45 minutes to do 1 hole. I used a carbide tipped masonry bit per the suggestion of a industrial machine tool and supply co. I also tried using a 1/4" bit first and then progressing to a 3/8" bit. So, I wound up just installing 1 bolt due to time restraints. I have done this repair a few times before but it's been awhile and I don't remember it taking this long to drill thru the plate. I used a good low rpm electric drill vsr 0-600 rpms. Any drill bit recommendations? Thanks, Bob Hull __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
