[Amel Yacht Owners] Windlass bolt to deck
So I can agree that the cleanest final solution is likely to drill out the bolt and then drill through the fiberglass so that a bolt can be completely through with washer/nut on the end in the bow locker. Cobalt bit is a bit help in that. Keeping the bit inside the bolt being drilled sounds tricky and if it wanders out I may be in trouble with a partially done job. Maybe do a smaller “pilot” hole, maybe 1/8” through the center than move up to larger bits.
Since I still have about 1” of the sheared off bolt above the deck, I will soak it with penetrating oil for a while and then apply a pipe wrench to see if I can turn it out. Worst case it breaks at the deck line and on to the drill method. I think even if I miraculously get the bolt out, I would still drill through to allow a nut on the bottom of this bolt. Any ideas as to why this 1 of 4 bolts was done differently by Amel?

Hi mike. I drilled mine out and put a bolt through. I now have a nut top and bottom On Oct 17, 2016 4:33 AM, "'Mike Ondra' mdondra@... [amelyachtowners]" <amelyachtowners@...> wrote:

If you took this problem to a machinist they would try drilling out the bolt with a left hand drill (cuts turning counter clockwise). If you lead a good and pure life it just might grab and unscrew the bolt halfway down. Not something your corner hardware store has, but easy to find online. Some of this has already been said, but it can’t hurt to repeat… Do soak the bolt with penetrating oil. This is a case where it is very likely to help by softening the rust. Overnight is not too long to let it soak. Multiple applications over several days is best. Before starting to drill, grind the face of the bolt off flush and smooth and be sure to use a center punch to give you a starting dimple for the drill. Do not skip this step! It’s impossible to get a good start drilling in the center of a stainless bolt, especially with a hand drill, if you do not dimple it first. Do not try and drill it out all in one go, start with a small bit to make a pilot hole. Go slow. Slow drill speed and gentle pressure. Use new, or freshly sharpened bits. Cobalt bits are worth the extra cost. When drilling stainless steel, use cutting oil. It will help keep your bit sharp and cutting smoothly and help reduce the chance of breaking the bit. Or, you can try a “Speed Out” bolt remover. I have had good luck with those, but never had any luck with the more commonly found “Eazy-Out”. Good Luck with this! Anytime a bolt breaks off it is a real hassle.

As you might have seen on my Windlass overhaul illustration, I have tools for broken bolt, screw, etc. This is a good idea to have on board… I actually just purchase more… If you had access to a Irwin Hanson Bolt Extractor (Set 54009) that cost $65 that would be good for this project and the future… http://www.irwin.com/tools/browse/screw-bolt-extractors/bolt-extractors I also recently purchase the Irwin Hanson 11135 crew extractor… but they seem to have a new 48 pieces http://www.irwin.com/tools/screw-bolt-extractors/48pc-master-extraction-set Sincerely, Alexandre SM2K #289 NIKIMAT Club Nautico de San Juan, Puerto Rico -------------------------------------------- On Mon, 10/17/16, Danny and Yvonne SIMMS simms@...

Well I had to use these on 2 projects so far and looks like it will happened again in the future...

Hello Mike, |

The part about a “good and pure life” is a problem. I will soak the hell out of it and put a pipe wrench on the stud to see if that breaks the bolt free. If it shears off I’ll drill it out. Thanks for the insights. Mike
