Thanks for the kind words and welcome. I must admit that I have been devouring this forum over the last few months - it has been a joy to see. And I have learnt so much from other people's posts, so thank you to everyone that has shared what they've done.

The original paper that came up with the somewhat strange design is here: https://link.springer.com/article/10.1007/s00226-020-01169-2 (I did link to it in the original post, but haven't quite got to grips with the forum code). There is actually a second, more complicated shape that I would like to try out next, that is in that paper. It is certainly beyond my limited woodworking skills, and I suspect would be easiest to do a first pass with a CNC. I'm trying to teach myself CAD, but it is a steep learning curve. Out of interest, has anyone ever played around with bat shapes with foam and industrial plasticine (as used for designing cars I think)? I suspect not, as it won't be possible to check how it actually feels.

I'm going to have get a bat gauge now, just to see if it squeezes through!

And if anyone can remember the GN model that Kulli mentioned, then I'd be really interested to hear. Or any other shape that was similar.

Anyone got access to the paper through work or something. 35 seems a bit steep

That is awesome in so many ways! Nice job!

Small details like the rainbow twine are really cool. Always good to see something out of the ordinary.

It looks like a lot of wood has been lost up top compared to the templates so it would be great to hear how it plays and feels

I don't really get the Algobat. The claim was to reduce the cost of bats and I guess they meant that the shape alone, made in any old wood, would make a bat as good as a more common shape with the very best wood and bat making??? By "good", they meant maximum energy transfer through minimum vibrations which is a very simplistic way of trying to make a "good" bat which may or may not work in the real world.

@Kulli the comparisons seem to be more towards the Nemisis

Looks a bit like the illegitimate offspring of a GN Nemesis and an old school Woodworm. Very interesting.

The other bat is similar but with a spine scoop added above the swell?

You might want to remeasure the specs, a 37cm edge would be nice to see though.

Pictures are fixed and they look great!

How did you create those templates? Also, can you add pictures of the drill sanders you used?

Whoops - it took me a while to spot the clues about edge size and gauges. I put down the wrong units for some of them (I did say I wasnt an engineer!). Sorry, I think you all spotted it.

They should be:

Edge: 37 mm
Spine: 60 mm
Toe: 14-33 mm
Shoulders: 12 mm
Sweet spot (estimated): 8-23 cm from toe

I havent quite been able to get my head round those Algobats either. I dont doubt that the algorithm is doing what its supposed to, but the parameter its aiming for isnt necessarily going to mean that a bat is good or not. I think they do mention other studies and what theyve looked at. I guess if there were 3D scans of good bats, then they could be analysed in the same way to see how they compare. Surely thats been done?!

But back to this bat. I actually ended up taking less out above the swell than the templates suggest - in that photo theyre not actually reaching the face yet. In the original design the concaving would go below the edge level! Instead I left a lot more spine all the way to the handle than in the design in the paper. If not, it would have been too heavy, so I took more out near the toe, to raise the middle a bit (its still a little low for my liking) and improve pick up. The next bat Id like to make a version of is the one in the diagram @DorsetDan posted, with the spine scoop above the swell. But with a higher middle probably.

@InternalTraining Here are the things I used. Mostly the ones in the blue case, but theyre coarse so had to be careful. The discs were pretty good too, especially with the foam as it was more forgiving. The tiny cylinders are meant for Dremels and werent much use for this bat in the end. For the templates I drew the shapes to scale in Adobe Illustrator and printed them out, stuck them on cardboard and cut them out.



And other things used that I forgot to mention:

Stickers - Diginate. Really good service, stickers are nice, colours came out bright, and were much cheaper than the reverse printed ones. Not sure yet if theyll smudge when hit. The stickers on this bat have metallic parts, which look great, but I also got a set with transparent background and the colours are a bit brighter I think. https://diginate.com/

Oil - Salix linseed wax. Really nice to use compared to the mess I used to leave with the oil. Just one coat.

Great shape @marsbug. This is something I have been planning to get made someday, provided the bat maker agrees to do it; unfortunately I do not have the skills to do it myself.

Actually, what I think it reminds me of is a laminate @jamferg had from @hit4six years ago. Was GN stickered but not a GN bat. All photos on the forum of it seem to have gone though.

Jamferg seems long gone but do you remember it Craig, or even better have some photos stashed away?

Very good memory @Kulli - Having trawled through the darkest depths of an old Photobucket account, I have found them. This was the bat:

Didn't Hunts make a bat almost identical to this and put honeycomb or something in the gaps?
