If you think your pendulum is out...
Grind a comb then look at the ground side, turn it to catch the light. The grind marks should run straight up the teeth, no angles.
Also, same with cutters, the ground side should be 1 shine of metal... if there's a white line around the teeth, then it's not sharp yet and needs ground more. Don't over heat them, bug keep grinding until the dull edges are gone. Cutters over head quickly

shearer told me years ago easier to push a pendulum than push blunt gear.
had a old style lister grinder with the single plates found it. did not give a very good grind think too slow
think the big thing is. cockys leave there gear on too long then dont grind it out fully so always getting a poorer cut

mate had a shearer help him get. set up. got him standing in the right place then drew around his feet so stood in the right place each time grinding ...only works if yer grinder. dose not move tho. hahahaTbh My grinding isn't consistent enough and I'm trying to improve it , thought it might be to do with having an old lister belt driven bit smaller diameter 14 inch wheel grinder, but its probably more to do with inexperience or not getting the pendulum position quite right on all the different types of gear weve got , going to stick with only one type of comb and one type of cutter in the future .
Trouble is with my old grinder , you got only one disc on at a time, hes single sided, so got to take off from the spindle swap between the disc for
combs and cutters one, apart from that hes fine , cant beat grinding your own gear.
I did do the wool board grinding session years ago, but that s all learnt and forgotten by now

I am so sore from laughing
f**k shearing then, I can't even handle reading about handpieces ?

.....is the direction of these grind lines any good?
fe w pits on that cutter i see, didnt see them before the photo..i must admit..
not actully ure if hes lister or not tbh , just v belt drive from a separate motor, vintage disc and bearing set up, was built for a flat belt origanally and hes got 14 inch discs instead of modern 14.5 disc dia.
standard papers hang out over a little bit that's all, can trim them but i just leave it.
this speed shows on the spindle ,

Others may disagree, and this is just my opinion.
I'm very happy for others to comment/correct me;
I think I personally would lengthen your pendulum slightly (so that the come is lower on the disc when you're grinding).
Look at my screen shot of your pic. Look at the grind marks where I've circled in green, I would have them up the teeth where I've circled in red.
If you look up the comb teeth you can see your marks don't run straight. You're not far away, just drop it slightly.
For your cutters, it's harder to tell but to me thar looks like they're grinding harder to the nose/tips.
What pendulum do you have? Taking both things into account I'm almost wondering if you're using the cutter side for the combs and comb side for the cutters

Annoyingly I can't photo my gear to show what I mean... its all sitting in my box, on the clipping trailer, up at my mates
supershear pendulum , in good nick,Annoyingly I can't photo my gear to show what I mean... its all sitting in my box, on the clipping trailer, up at my mates
i' ll lengthen him a bit and have another go , would (finishing ) position on disc horizontally make any difference to the lines ? as i guess closer to the spindle would be a tighter circle .
i noticed this morning that he actually is hanging a bit too close from the top which would teeth grind a bit more than heel grind tbh so ill move him off from the to a bit as well...
trouble is with only one hanging point and disc means i'll have to alter everything each time for cutters and combs, could put a nick on the pendulum tho as mark . when i'm happy with the length. not sure about using 60 grit tho..
about pressure, i have very recently tried more pressure to get sparks from all teeth evenly, and that's seems better , without getting too hot.before i had some parts where there was very few sparks , but i find i need to push bit harder than the '2k bag of sugar' they said on the woolboard course

Supershear pendulum here too. It'll say which side is for combs and which is for cutters
Don't alter it each time. Set it up for the comb and leave it be, as the comb grind it the more important. (1 disc and 1 hanger it should all be set correct anyway, as long as you flip pins on the pendulum)
You want to move the hanger towards you a little, enough so that the comb is just clear off the disc as it hangs freely by itself - we are talking 2 or 3mm here - 5mm max - no more than that. Stand side on to the disc, and as you push the pendulum forward on to the disc, the heel (bottom edge) should touch before the nose (top)
You should finish grinding pretty much with the pendulum hanging plum vertical from the hanger. The comb/cutter should strike the horizontal line through the spindle at this point. The hanger should be positioned so that when the pendulum is hanging in this final position, the outside of the comb is about 1 inch away from the edge of the disc (you've an older, smaller disc? You may need to run a little closer to the outer edge of the disc - but I'm not very sure on that part)
The sparks should be nice and even coming from all teeth and coming straight up, off the tips of the comb/cutter.
That's all the theory I was taught. I need to brush up my technique a wee bit but everything is set up right

It's just occurred to me... what you've said there - does your pendulum have a comb and cutter sides?
If yours has 1 side only, you really need a 2nd pendulum - or a new one which can do both jobs (that'd be my choice because if you get it set for the comb, the cutter side will automatically be right when you turn it round)

Hopefully this is of some use. For a Heiniger set-up but the process is fairly universal.
i lowered the pendulum a fair bit (3/4inch approx.)to see the difference, it now looks low to me in relation to the spindle and pics/advice ...but its made a noticeable difference to the lines ir
..... on the comb (different comb ) if you can see them in the pic?

yes he has got the turning bit with cutter written on one side and comb the other, pins lower for cutter?
edit , some times if it a poorly ground one they do seem to cut wool better on the non flared (right hand ) bottom tooth side i think
before i was going off the edge of disc too much with the top tooth possibly ,

That looks a lot better to me
Contrary to the heiniger paper posted above, you shouldn't run the comb off the edge of the disc. It's only a fraction of time, but it isn't getting ground when the rest of the comb still is. To get an even grind, the whole comb needs ground the same

Here's a good video how to set up grinding
yeah, David s vid is simpler to follow, it does seem to me though that my pendulum needs to be slightly lower to get the lines as straight up s possible, that's the bit that baffles me, will try moving it in towards the spindle next just to see if that makes any difference, he is bout a centimeter or so from the outside atm.......being a bit of a perfectionist...
I've seen him shear a time or 2 have you? boy is was he fast and smooth with it best shearer ever .imo.
