Ok I know this may be a broad subject with different opinions. But here it goes anyway. I need a sharpening device. I had the jigs from PSI for my grinder but my grinder is a high speed amd I am sure the stones are not what is needed to sharpen. So its either buy the stones or a new grinder or a wet wheel system. Any and all suggestion will be greatly appreciated.
Thanks,

Each to his own Brent. Sharpening is the bane of kmany a turners existence.
I have high spee grinder and a Jig called a Heligrind which works beautifully in the hands of an expert!
I have seen the results a complete novice produced using a Tormek Wetstone Grinder. Never seen such sharp tools!!
Whatever way you go I was given a great tip by an old turner: Take some mild steel rod and practise your sharpening with that. You can try agles and the speed with which you complete the task without grinding away lots of money on your good tools!!
 
Hi Brent, A high speed grinder used too aggresively will take the temper out of the tool making it "soft" and then it will not hold an edge long at all. A slow speed, wet grinder will put a much better edge on and is more forgiving learning how to use it. Also a slow speed grinder for sharpening will have the right wheel already on. I saw one at Harbor Freight last week that had a good price, can not remember price, but it impressed me at the time. I would have bought it, but I got two sharpening grinders in the shop now. LOML might not understand the need for a third, as she is still pondering the need for #2:D. Hope this helps.
 
Turners have been using high speed grinders for ages with no problems. You just need to know how to do it. Try what Arthur suggested, PRACTICE is the key.

Have to disagree with the "no problems" comment. Some may use high speed and get away with it. But often there is a cost in terms of ruined tools. Yes, if they "know how" it can be done. But that learning curve comes after many ruined tools. BTW, practice is necessary regardless of the speed.
 
Hi, you can be working with grinders for 35 years and still not get it,I didn`t know what sharp was till i got the Scheppach slow speed grinder. I think the main reason is that you can get close up and personal without fear of getting hurt the way you can with a high speed grinder with sparks flying all over at high speeds and real loud. My 2 1/2 cents,, Carl
 
Thats a good video but I thought you shouldn't sharpen on the sides of the grinding wheel? Does anything think this is worth paying the $4.95 for the plans?

We went with a Woodturner's Sharpening Kit[ http://www.woodcraft.com/family.aspx?FamilyID=20355 ] from Woodcraft. It's a slow speed grinder and jig. It cost $169.

I don't think I would call 1725 RPM exactly slow speed, actually that's a very common medium speed motor, slow speed seems to me to imply around or under 100 RPM. Granted it is slower than most bench grinders which usually run around 3450 RPM.
