Title: Holmegaard bow. Updated!
Post by: Aksel on May 18, 2023, 10:24:11 am
Hello, I decided to make a bow close in size to the smaller of the two stone age bows found in Holmegård in Denmark, dating back to apr. 9000 years ago. I stretched the original measurements out, added 4 inches in total to 64" instead of original bow´s 60".  The original bow was probably heavy;  70+ lbs or so. By stretching it and taking a couple millimeter off it´s thickness and width, this bow pulls #50 @27". One limb is reflexed which gives it a bit of a wonky brace. That famous shoulder is very subtle and appear only on one limb.

It is made from European elm and I decided to leave the finished bow rather rough, no sand paper just rubbing its surface smoth with a glass jar. I stained it with a mix of earth pigments and oil.

Not a scientific replica but it turned out a very nice bow!

Edit: I shortened the bow, see page 2.

very nice
Definetly you can hear the echo of the human history in those bows
Is the string natural?

Yes there is something almost magical over those old bows. The string is linnen, but this bow really should have a sinew string..

Very neat bow!  I'm psyching myself up to start a yew rendition of the Meare Heath bow.  Minor details like how to best lay it, etc.  Target draw weight will be 40-45#.  Relearning how to post pictures will help (lol) :fp

Thanks for kind comments. This is such a perfect design. Short, every part of the bow doing some work.

willie : The original Holmegård was made from a 2" sapling. I used a 4" sapling, so to get to the right cross section where thickness and width stay true to the original I had to round its back sides to get that high back crown shape of a very small sapling.

Hawkdancer: I look forward seeing that Meare Heath bow! It is a very curious big bow, worked on all sides and with the handle section sunk down a few year rings on the back. Maybe safest to avoid that dubious feature...!

Real Cool! Sinew wrapped nocks? a close up on one of them would be nice :) I dont know enough about these older European bows but always wanted to give it a shot. Great example of that era you made there and for a primitive archery forum. Like it a lot.

That is definitly a nice bow.

For smoothing the surface you should give Field Horsetail (Ackerschachtelhalm) a chance  ;)

Thanks Pappy, mike, chumash.

Here´s the nock. Just cheap Jute twine dipped in glue and wrapped/ tied on. I guess most people find it un-aesthetically or worry about the string coming off, I do most of my bow nocks like this and never have the nock fail and string coming off. Infact have I had more problems of string coming off or wood splitting with side and pin nocks. And you get really narrow low mass bow tips with a tied on nock.

Chumash: I´ve read about stone age people using Field Horsetail to polish wood. Must give it a go one day.

I also include a picture before I stained the bow where you easier can see how small that shoulder is on the one limb.

The original Holmegård was made from a 2" sapling.

Thanks, such a high crown calls for elm or a tension strong wood.

That's a very nice Holmegaard bow, Aksel. Looks like it could have been made thousands of years ago. Well done!  :OK

Great holmegaard!

And I would have been sure you had not only sanded, but polished with steel wool, etc.! Amazing what a little pressure alone will do.

Sweet bow, I've always loved these holmegaard bows. There's something so simple and yet so complex and deliberate about them

Thanks for all the comments guys. I was shooting the bow for a while and I did - comparing it to my other good bows - feel it shot slightly spongy. So I shortened it to the original bow´s length (TtT: 154 cm/ 60") and re-positioned the shoulders on the top limb to its proper place. I suspect the spongy feel upon release of the arrow was due to the bow being too narrow for its length. Now the bow is very close to original measurements: 2-3 mm narrower and 0,5 -2 mm thinner. (1 mm = 0,04 inch). So pretty much bang on the original Holmegård´s measurements. Draw weight went up to 58 lbs @ 27" and that spongy feeling is gone. Also the tiller changed from a more round tiller to stiffer outer limbs and the handle start to put in a little work due to draw weight has gone up. Set rose marginally. It think the performance is now optimised for its design. Love this cool little bow.

New full draw:
