If you have one of these sharpeners or one similar, have you been able to sharpen a 16 inch jointer blade on it. I have a clone from Busy Bee Tools and while I can get a blade sharpened., it is touch and go for repeatability There seems to be too much play in the blade guide and the stone adjustment is dicey at best. I can sharpen a chisel or bench plane blade without too much difficulty. If you've had any luck with this unit can you describe what if any modifications you made.

Thanks
