just curious...please dont shoot the messenger

Im interested in this topic...given that I am no where near a place that sell anchors for cruising boats...

plenty of danforths and fishing boat traditinal anchors but Im not interested in that

ideas?

materials?

galvanised or stainless or mild steel painted?

really would like some ideas from like minded people, I need one for my boat, in the 35lb range Id love that new mantus, and the price looks great but unless they ship for free im screwed!

HAPPY NEW YEAR in advance

christian from 3 doors down! jajaja:)

Are you in Salvador now?...You probably have access to welders that work comparatively cheap...Stainless is the best but may be harder to get there... Galvanized is toxic to weld so is usually welded up first and then galvanized..Mild steel and painted will probably be the cheapest and easiest and will last a reasonable time...There are quite a few home project anchors in this part of the coast...copies of new style anchors matching shape and angle which is important...Most were oversized as the cost of a little extra material is small compared to labor ...and I personally haven't heard of any failures...

I think given the other thread, this may not be a bad idea for you. I would use galvanized steel, not stainless if you plan on actually using it. Stainless is not good for use underwater. If you want it to be shiny on deck and use it only a few nights a year then stainless is good. Seems you should be able to find some used ones locally? Perhaps you could become a distributor for one of the anchor companies and sell them out of your restaurant! I can here it now "I would like the fish special, baked potato, double vegetable, a rum and coke oh and throw in and a 35 pound anchor on the side, to go please! And make it quick my boat is dragging!"

You make me want to come down and visit. I had a girl friend in college who was from there back in the early 80's I think her father was some big wig in the government, and one of her friends told me to watch out for him! But you know how you can be when you are young, dumb and in love. Luckily I was only in love for a week or so! :laugher:laugher:laugher

Yes:) I am a welder by trade. Had some scrap so the cost of metal was $0 dollars. You can use stainless steel. It would be the best for a home built. I would recommend 316 SS, It can be cut with a thin grinding wheel, You can dill it use a slow speed on the drill and lots of oil to cool the bit. You can weld it... tig is best, stick then mig,
Economies of scale might make it better to Buy:) because they make thousands you will make ? They test and you will toss it and hope ? The post that I just liked says so much ! Find a local they might get into making it more like an art piece. Maybe you can try a trade school.
Worse case get some Concrete , Rod, Chain. Rocks and heavy junk
Happy New Year, Lou

I saw someone build a knockoff on another forum. DO not remember what brand they copied, but IIRC they too were a welder or equal, and had access to some cheap material, so had fun with it.

The only thing I have made is deadweight moorings.

1) build a box
2) drop old engine block into box
3) fill box with large scrap steel
4) fill box with concrete
5) insert a couple of galvanized rings
6) let concrete cure
7) drop box in water

For actual anchors I can't help much... Take a trip to the states and carry one home as luggage?

I've made many.
Stainless will eat the first links of a galvanized chain with electrolysis if you leave it down any length of time.
thats very informative...there are no good galvanizers down here so I was pushing towards stainless since I have had many stuff in stainless made down here including my new chainplates!

having said that I havent heard of too many stainless anchors and was wondering if there is that little oxygen and stuff in mud, clay sand we have down here

is there a way to ANODE the anchor to chain connection? to prevent what you are saying

I also have access to wonderful plain old steel...and cheap metal paint...I think this would be the easiest no?

thanks:)

Surface freight shouldn't be that much; have the seller strap it to a pallet and put on a truck (I'd guess no more than $150.00). Even vessel shipping on something like an anchor on a pallet is ridiculously cheap.
Best answer for you though, would be to find someone there who ships in containers regularly (markets, hardware stores, fabricators, auto parts stores, electric/appliance stores, etc) and ask if you can have it added at the assembly point. Then it's just surface freight to where ever the container is from the point of sale, probably less than $100.00.
I'm sure you have customs wrapped around your little finger by now, so that's covered.
Bestest of all would be to have a cruiser bring one down on the boat. If I were headed that way, I'd sure love to have a friend that ran a restaurant. I'm sure the forums would help with that option.
Personally, I wouldn't take the chance on a home made anchor, especially in stainless. There is a science to the design and a small error in angle or balance could render the thing useless. Remember all the trouble Rocna had with the wrong steel? None of the "knock off" plows ever worked as well as the genuine CQR's either.
But of course, my signature says it all about that, as far as I'm concerned.

It was on the Jeanneau forum and he had detailed each step with pictures. The end result was pretty impressive, but he'd made a copy of a a modern anchor and quickly took down his posts.

Zanshin,

I was going to look there for the pics/thread, but have not. Did not know things were down. WOnder if Malcolm did that, or the op?

It was a pretty copy none the less.

If you make a complete copy you might have some legal issue ? I do not think one anchor is worth the time for a company to press it, If you started a trend. It would change thoughts. There can always be the lets hang the first one high for all to see attitude. Now who wants to be first ?
I would say the pictures left before the luck ran out.
good day, Lou

Lou,
I suspect you are right. A single incident isn't likely to be worth the effort. But documenting how you did the build and posting it in a public forum so others could do it, too, could be an issue. Especially if there are patents or trademarks involved.

Unless you tried to sell it, I doubt anyone would care.

But, I had never thought of actually making one as I'm not much of a welder. But, a good friend of my mine's father is certified to weld nuclear submarines. I imagine he wouldn't have much trouble welding one together that would be as good as one from the factory.

yeah the iffy part is the fact that its a NEW anchor so copying it would undoubtedly recreate or make worse any issues said anchor has

of course if I started making anchors and called them MANTII instead of mantus and sold them as an exact copy of said anchor id be in trouble...but not what I was talking about

sorry for the confusion

I have a good welder friend...he made parts for my motorcycle from stainless using TIG...

skidplates, kickstands, etc...really good

honestly thought making one would save me 300-400 on shipping but be about the same as a new one stateside...

A patent has a life of only 20 years, so anything over 20 years old is public domain. I left a kid with a welding shop on Niue, patterns for Delta anchors; 22 lb., 35 lb., 55lb., and 130 lb. I wonder if he made any. Never got back there since then.
I have concluded that, with my anchor in the water 95% of the time , welding a sacrificial zinc on gives it as much protection as galvanizing, and is simpler and cheaper. That doesn't work for marina queens ,which rarely get their anchors wet.
For some anchors, getting the angles right is critical. 1 degree over 32 degrees for a Danforth reduces holding power by 50%. Much better to be slightly under 32 degrees. 30 degrees works well. Any more than 32 degrees and the anchor flips up on its side, and drags forever without even trying to dig in . Best test any anchor on a beach, before relying on it. Some can be made far less prone to fouling, by welding 3 /8th galv rods on at critical; points ( galvanized spikes).Again beach tests will show you where, when you try to deliberately foul them.

The next Deltas I build, I will leave the shank off several, for easy storage. If I lose an anchor, I can easily weld the shank on then.
