Drilling Stainless

I have to drill several small holes (for #6 screws) in 1 7/8" stainless tubing. I got the right sized Cobolt bits as the group recommended awhile ago. My problem is that the placement needs to be reasonably accurate. How do I keep the drill bit from walking all over the tube when I try to drill it. Is there some type of guide that will hold the bit steady while I drill? Something I can buy or make? Any ideas? Thanks, Wayne

Maybe something like these specifically for drilling in pipe/tubing. http://www.skygeek.com/ats-36.html http://www.trick-tools.com/Punch_Drilling/drill_rite_drill_guide.html Kirk On 8/26/2010 1:03 PM, Michael Robinson wrote: > > Center punch: > http://www.google.com/products/catalog?q=center+punch&hl=en&cid=17705507848971684611&ei=ucd2TMrKH4faNZ7BqMUB&sa=title&ved=0CFEQ8wIwBjgA#p > <http://www.google.com/products/catalog?q=center+punch&hl=en&cid=17705507848971684611&ei=ucd2TMrKH4faNZ7BqMUB&sa=title&ved=0CFEQ8wIwBjgA#p> > > Drill *_slowly_* and lube with cutting oil. > > */Mike/* > *//* > > > > > ------------------------------------------------------------------------------ > To: Ca… [at] yahoogroups.com > From: wa… [at] yahoo.com > Date: Thu, 26 Aug 2010 12:48:09 -0700 > Subject: [Cal_Boats] Drilling Stainless > > > > I have to drill several small holes (for #6 screws) in 1 7/8" stainless > tubing.

Drilling on something round is problematic, if accuracy is required to template two pieces then there are other problems to deal with. It might help to know what you are doing. I sometimes drill only one hole in a pattern, then put pieces together, then drill the farthest hole while the assy is clamped., insert the bolt and continue – like the torque pattern on a head of a car. If the holes have to match either side of the tube, then usually drilling two holes is best – both from the outside. dEmO in Plutoniumville From: Ca… [at] yahoogroups.com [mailto:Ca… [at] yahoogroups.com] On Behalf Of GE… [at] comcast.net Sent: Thursday, August 26, 2010 12:53 PM To: Cal Boats Subject: Re: [Cal_Boats] Drilling Stainless Try a sharp punch tap with hammer to set a start.

And a drill press and a machine vice. Also, drill a hole 1/2 the diameter first.

Wayne, An idea popped into my head. Take a short piece of one by four, say six inches long. Cut a V-shape about half an inch deep using two cuts of a saw at 45 degrees relative to the wood surface, in the middle accross it, then drill a hole thru the middle of the V holding the drill as vertical as you can. Then clamp the V- shape to the tube using one or two C-clamps, and then drill through the wood hole to make your hole. I've never tried doing that that way, but I bet it would work. If you need to install a two hole bracket, say, bolt the part to the tube and use the second hole in the bracket to find and make the second drill hole. Hope it works.

In Rock Hall two boats down a lad was drilling his SS tubing to repair his Bimini. He had this rather cool guide that clamped onto the tube and held the bit steady while he was drilling. Asked where he got it, he said ebay. Never seen it again and cant find it. Anyone have a clue as that was one handy piece of kit. /ch On Thu, Aug 26, 2010 at 4:03 PM, Michael Robinson <mi… [at] hotmail.com > wrote: > > > Center punch: > > http://www.google.com/products/catalog?q=center+punch&hl=en&cid=17705507848971684611&ei=ucd2TMrKH4faNZ7BqMUB&sa=title&ved=0CFEQ8wIwBjgA#p > > > Drill *slowly* and lube with cutting oil. > > *Mike* > ** > > > > > > > ------------------------------ > To: Ca… [at] yahoogroups.com > From: wa… [at] yahoo.com > Date: Thu, 26 Aug 2010 12:48:09 -0700 > Subject: [Cal_Boats] Drilling Stainless > > > > I have to drill several small holes (for #6 screws) in 1 7/8" stainless > tubing.

You need to use a sharp center punch. Remember to use some oil to lubricate and cool the bit, or you could burn up the drill bit tip.

Half of a number 6 is a dang small hole. It does indicate that a a very stable set-up is needed with good speed and pressure control to keep from snapping a bunch of bits (of course meaning that the B&D variable hand drill probably will be hard put to do the trick). Might work with a lot of caution.

Yup, number six is already pretty small. Sounds like another case where...silly cone grease to the rescue!

PS. The reason I recommended making a simple wooden jig to make the hole in my previous reply is, if this is a stanchion, and, say, not very well secured to a fiberglass boat deck, it might not be a good idea to give it a smart, sharp wack with a ball peen hammer and a center punch. Of course, on the other hand, if'n it isn't well secured, it would be a good opportunity to remove it from the boat and refasten it properly with a broad base plate below deck.

Wayne You could build a jig out of wood and use a drill bushing to guide the drill. Using a 2x4, drill a 1 7/8 hole. Cut though center of hole. Now you install a drill bushing for your size drill in one half of 2x4. You can make a bushing or buy one http://www.mcmaster.com/#drill-bushings-and-liners/=8kwlfn this is just a example of a # 6 bushing. I have built bushings out of brass, aluminum and steel. It depends on have many holes you are going to drill. Cut a small amount from the second unused half (for better clamping action). Center punch drill site. Clamp the two halves together. Drill slow and use cutting oil. Tim's idea of drill both sides does work better than drilling straight though. I don't know what tooling you have. If you have a drill press it goes much better.

Great job. Now I know why I enjoy your posts. Used to work for your competitor Agra-Moneco now AMEC as an environmental consultant. Sailing content; monitoring ice floes in the arctic to see if a CAL-20 can do the North West passage. As of yesterday, its was open. Only 1500 miles from Baffin Island to Tuk and with a 3 foot draft, its shoal friendly. Short season however..:) http://nsidc.org/data/seaice_index/images/daily_images/N_daily_extent_hires.png (and if you think I;m serious I have property for sale in Florida) /ch On Tue, Aug 31, 2010 at 10:45 AM, <ti… [at] ch2m.com> wrote: > > > Just in case there was interest.. the project I am on. > > > > http://www.neimagazine.com/story.asp?sectioncode=76&storyCode=2057284 > > > > Plutonium -Ville. > > > > Sailing content – stopping the waste from reaching the Columbia River > > > > dEmO > > > > *From:* Ca… [at] yahoogroups.com [mailto:Ca… [at] yahoogroups.com] *On > Behalf Of *Gerald Sobel > *Sent:* Saturday, August 28, 2010 2:06 AM > *To:* Ca… [at] yahoogroups.com > *Subject:* Re: [Cal_Boats] Drilling Stainless > > > > > > Gad, the last thing we need is a Cal 40 with radioactive contamination to > add to its unfortunate mid ocean experience with antibiotic resistant flesh > eating bacteria! > dEMo is going to turn into the 'Monster from the Blue Lagoon'.
