This is a short video showing how I changed the shearing machine. The sheep is now rolled completely over 360 degrees instead of side to side. It lets me shear the sheep in long continious blows/strokes. I can shear sheep very easily in under two minutes and do it all day long even at 60 years old. The machine is not finished though. I must build the front leg restraints and make the conveyor of the table also rotate under power but in the opposite direction as the legs are rotated. It is all designed I just have to find the time to build the rest.

Don't you mean "shear excitement"?

I wish I could post a PDF to this site via Photobucket but it is not possible.

That really is quite impressive! Two minutes each, does that include catching and loading etc? 240 in an eight hour day that would almost get you a job in New Zealand (but I dont think we have many sheep nowadays their place having been taken by dairy cows!).

That means thirty and hour and I am not by any means a great shearer. More of a wool chipper!

Ok, maybe just a little! But three minutes was really easy and I did many in under two minutes but not all!

I think that sheep was thinking she was really going to get screwed this time!

I posted a link to a PDF file of a very crude animation that I made. It is how the hopefully finished machine will operate. You should view the PDF with Adobe's reader as it will let you grab the file and look at it from any angle.

Bruce---You are getting very good with your 3D animations. When you get the front leg restraints finished, make sure they rotate in the correct direction. I have this hilarious image in my head of a bunch of corkscrew shaped sheep running around your farm!!! Great work!!!----Brian

Hey Brian, Thanks for the compliment. That means a lot coming from you.

If the front leg restraints rotate the opposite direction then the wool will be made into yarn straight off.

I wanna see videos of dizzy sheared sheep walking away from the machine after being spun around at 30rpm. :P

Might want to consider turning between centers. Your lathe dogs are a bit wobbly :)

If you drive the belt a little "faster" than the leg restraints, the leg restraints will put a bit less stress on the sheep. Of course, "faster" will be a variable, and dependent on how fat the sheep is.

Looked pretty effective even now without all the whistles and bells added.

Finest regards,

Two or three minutes is good, good for the sheep too as (I am sure you are well aware) being upside is very stressful for their innards, even fatal if it goes on too long, but much longer than a few minutes.

I have seen at lot of attempts over the years at making devices to ease the labour involved in shearing sheep and yours is the best I can recall, can I have the NZ agency?:D


P.S. Have you noticed any reluctance among your sheep to go near that shed?

I think the sheep don't like the machine but I also think they don't like the conventional way of shearing either.

Your almost at the point where you can take it on the county fair circuit and charge people a buck a ride!!!---Might help recoup some of the costs involved.

Perhaps you are right as certainly some sheep go to extreme lengths to avoid being shorn...

This guy hid out for six years before being found, his fleece when shorn was about 28kgs.

I was going to show a few of my mates here in sunny south Wales but the first one considered your film to be 'sheep porn' [which i thought was hilarious] and that i was a closet sheep lover, [lmao] However i can appreciate the design, i have chucked a few Ewes about as a younger man [ohhh dear] and appreciate how stromg you have to be to handle them.
the only thing i would need to shear a sheep with your machine is an automated aeroclens [battles purple nick spray] spray head as the poor animal would end up purple and covered in cuts.
the roller belt looks like it needs a tweak as the ewe looked like it was in torsion with a bit of lag, mind twisting them used to help strech the skin on the sides of the fleece so it may be a good thing too?
well done sir

now a voyeur of sheep porn!

Have you automated the wool copaction in the sack yet? Don't ask me how I know about this.

Really ingenious work.
