anchors making heavy/lead
« on: November 16, 2016, 09:15:14 »
As I would like to make the anchor operation workable I believe that I shall need an anchor with suitable weight to enable freefall on the release of the winch.
I have bought some anchors which stated brass but are in fact light cheapo metal with a brass/gold coating.  Clearly these may not be heavy enough to create the inertia needed to make the chain floe and thus the anchor drop by gravity.

I have bought some rings and red sand and thought of creating a mould using the anchors bought and then pouring lead into the mould to create some heavier anchors.

Has anyone cast any anchors for operational use or does anyone have different tips on achieving the freefall effect of the anchor.


I cannot be the first to desire this on a boat. The boat is 1:25 but the anchor is not over large bit typical Halls anchor type which may weigh. 14g.

Unfortunately Toby, I don't think you are going to achieve what you are looking for, 'cos your anchor (at 1/25 scale) will weigh only 0.0064% that of a "real" one.  You simply won't be able to get enough weight on the end of the chain to get it to run freely off the windlass.  But, you may be able to power it down if you use a reversible ESC on your windlass motor.

Thanks for your input Des.   :( oh dear then.
I will continue to experiment to check weight and mechanism once I have the deck finished and the Windlass fitted.

Hello Toby;I have a pair of stockless anchors that are solid brass and weigh-in at a hefty 45 grams.
I found them in India last year via EBay. They are available if you are interested.



They may be a size larger for your 1/25th scale but then, a hair bit bigger anchor is OK
around these parts.

Hello Michael
Thank you for your post and picture.
Are these 45g each or is that weight for the pair.

So about 1 inch wide. I don't think that is too big. But as I say will check the boat measurement when I get back home.

They weigh 45 grams each and are 1 3/8 inches wide Toby. I have two
pairs of them so don't hurry home, they will be well and warm on my
desk here. Trave safely my friend.

Thank you Michael.

Will be in touch. Hope to see the old boats on the River Spree.

No problem, on my Smit Kamara in 1:50 it also works....

Great. I will let you know the outcome when I return to the Danube build for I am trying to complete the Imara / Perseverance build at the moment.
Free fall then winch up looks good.  MGS/MGC ideas are effective.

The anchors from Michael are super.  Now to find some for the 1/32 Perseverance
