[Rhodes22-list] Unbolted track

Tue Jul 27 11:59:54 EDT 2021

I use SHARP cobalt (Kobalt) bits in a drill press turning 1600 RPM, max, WITH cutting oil. Go slowly, keep the drill at right angles to the material and peck regularly (withdraw to clean flutes). If you really have trouble with 316, buy 303/304 stainless and save $$ on the material and drills (use HSS bits). 316 is recommended in marine environments for corrosion resistance but if it is typically inside the cabin or lazarette it will help.Mike

What tools do you have to cut anddrill 1/4 inch of the 316 stainless steel?Just curious. This info could give some of us hope.CaryS/V Whisper '86On Tue, Jul 27, 2021 at 11:25 AM mweisner <mweisner at ebsmed.com> wrote:> I typically use 1/4" thick 316 stainless steel sheets.
