What don't you like about the Conical clamp's I love mine and I think they should make them stock.
Do you have a new or older K02 if you have the older style K02 where the guide rod goes into the tube and it's all made out of flat aluminum and the barrel part the holds the ball bearing's for the up and down movement of the guide rod when sharpening that's the older style of Turret on the K02 and you can get anywhere near as low of angle's with it as you can with the newer Turret.
In the picture below is the new Turret or at least that's what I call it's the anodized black part that's on top where the guide rod goes into,with that one I can sharpen a Japanese Chef knife down to 9 degree's if I wanted to I just sharpen mine at 11 degree's.The reason you sharpen at lower angles with the newer Turret is because the rod is threaded all the way up to the Black Anodized part where on the older version you have a silver part that goes down the shaft a good bit witch limit's how low the Turret can be lowered.
If Tsprof will sell a Turret assembly you can retro fit it onto an older K02 without any problems I have an older and a newer version and I checked and it will work,you do not need the newer rack and pinion style lifting unit either the old plane jane one you raise and lower by hand will work just fine and that's what I have on my older K02.
Also if you look at the picture below I cut the tab's back on the guide rod because I plane to always use edge pro format stones and I have a spare guide rod.
The reason for me cutting the tab's back was because at really low angle's I could not get the full stroke of the stone without the tab's hitting the black part of the Turret,I could be wrong but I'm pretty sure it was when I sharpened my Japanese Chef knives the tab's would always hit.
