Well...I got the new wheel and the new shaft in. Installed.

Then ran the truing tool. Immediately screwed that up. Forgot to tighten it onto the tool rest so it bit in really hard and I had to take off a fair amount of wheel to get it back to true. While running the truing tool, due to the lack of concentricity I had to run the tool VERY slow multiple times. about 5 passes taking about 2-3 minutes each. Finally, got the wheel true. I will say, I don't know if my truing tool is worn out, or it is just the design, but that thing leaves the wheel seriously rough.

So then I used the  dressing stone on the rough side to smooth it out. I don't know if you're supposed to do that or not, considering my dressing stone is heavily concave on the smooth polish side, and basically unused on the other side, but I did it that way and it seemed to work.

Then I gave it a run on a very old, cheap poorly ground, misshapen pocket knife my dad had. I set the angle at 20 degrees and went to town. I got the knife much sharper than it started. But I did not fix the shape of the blade as I was trying to, and I rounded the corners on the stone, so I will have to true it again to get it square. Definitely take some serious practice to use this thing proper.

Think I will spend some more time watching videos before I ruin anything lol.

Rich,

I should hope it is a worthy upgrade. I definitely wasn't happy with the amount of walk there was on the other setup. So hoping these parts remedy that. I tried running the truing tool on it and it just wouldn't square it up, so hopefully I get better results. Tracking says delivery Thursday, so hopefully be able to give it a test this weekend.

jtyson,

Welcome to the forum.  I think you will really like your Tormek for all that you have to use it on.  If you grind HSS toolbits for your South Bend, look for Rich Colvin's platform jig for grinding/polishing them on the Tormek.  It should be in his Sharpening Handbook (link in his signature line?).  I haven't made one yet (I use nearly exclusively carbide inserts, except for cutoff tools) but it looks really handy. 

Based on the condition of your shaft and probably the nylon bushings, I think an upgrade to the stainless steel shaft and EZ-Lock nut is in order.  There are no "proper bearings" for any of these machines.  It grates me that there aren't, but the nylon bushing seem to do okay and given the low rpms that makes some sense. 

Once you use the truing tool to clean up the outer diameter of the stone, which trues it, you will eliminate that out of roundness and will be in good shape.  The side-to-side wobble is annoying but does not really adversely affect the sharpening processes. 

Good luck and keep us informed, particularly as you work though various tools you sharpen.

Rick

BTW, I didn't hear the clunk, clunk, clunk in the video.

Honestly I've never used the lathe, so it hadn't occurred to me to sharpen tools for it on the tormek. Maybe someday!

I ordered the new shaft and new zinc drive wheel. No clue when it will actually get here. Don't know that I'll try sharpening anything else until it does. And I don't think truing the wheel on the old shaft would make much sense.

As to the clunking noise, it is more audible when a tool is on the wheel. Running free it is there, but the mic on my phone probably didn't pick it up.

So for now, I wait.

GeoTech, no indentation on the tire.

Ken, thank you for the contact info. I may reach out to them. I'm not used to being able to contact a vendor with questions about a used item. That is typically why I spend time on forums, so I can get info from the collective.

Rich, thank you for going through and breaking each down for me.

I've been watching multiple youtube videos of people sharpening and it seems as though everyone's walks side to side a little, and plenty up and down a bit. I feel like this is probably a combo of loosely fitting plastic sleeves instead of proper bearings and the stone pulling down against them.

I'm interested to see if there are any alloy or stainless drive wheels, sealed bearings or other upgrades out there. Or if those would just be a waste of money.

I'm trying evaluate my situation here. I pulled it apart today. The shaft has a little pitting where the stone sits. It has some wear in the spot where the bearings sit. I put it in my old southbend lathe and spun it by hand and I can see that it is out of round by a few hundredths, but with the sloppy bearings, I don't know if that much really matters. The drive wheel is cracked and the slot where the pin fits is definitely damaged enough to be causing the clunk I think.

So, considering the parts I need, I'm going to price things and see where I'm at. I don't want to dump so much money into it that I could just buy another one.

Ken, I appreciate the thorough response. I have registered the unit with Tormek, got the handbook and I'm thumbing through it.

I am a bit of a crash course sort of guy, and didn't want to just read and watch videos, so today I decided to bolt things up, get it wet and turn it on to see if I could make a couple very ugly chisels and knives any more functional. Well, I think I have a problem or two with the unit. I didn't tear anything apart, but I took a short video to show my issue.

I tried running the truing tool, and it just wasn't right. I thought maybe the wheel was WAY out of round, but I think the shaft or maybe bushings/bearings may be bad. And the drive wheel, it is messed up. I've attached that picture too. Any pressure applied to either wheel results in a centrifugal "clunk, clunk, clunk" as if something is slipping or dropping.

Tell me what you guys think? I'll be doing some searching too.

So, admittedly, I bought this stuff off Craigslist about 2 years ago and it has been sitting on the work bench waiting for me to spend some time figuring it out. I just jumped on it not really knowing much about it. At $260 it seemed like a good deal with all the extra stuff. Then I paid another $60 or so for the honing wheel. I hope to use it for sharpening all sorts of goodies. I've got a lathe and a ton of tools, lots of chisels, pocket knives, kitchen knives, and maybe some straight razors if this is up to that much precision.

I've been watching some videos and reading the paperwork I've got. It is a SuperGrind 2000 I guess. No idea how old. Came with a bunch of jigs, I've figured out what some are, and others not yet. I've numbered photos. If you guys can clue me in to my missing stuff, that would be cool.

1. Turning tool jig
2. ???
3. Small knife holder
4. Large knife holder
5. ???
6. ???
7. Dressing stone (broken I know, but appears to have been used that way for some time)
8. Truing tool
9. Honing Paste
10. Axe/Hatchet tool
11. Extra small knife holder
12. Straight edge jig
13. ???
14. ??? - This one has a part number so I can google it, just haven't yet.
15. Knife holder? Maybe use with 5 or 6?
16. ???
17. Standard tool rest
18. Planer blade jig

There is also another truing tool that I didn't get in the picture, but it is just the diamond piece on a piece of stock with a hole through it. Don't know how it would be used.

I'm sure there are some other tools that I probably need. I have two of the plastic setting tools that I don't really understand how to use. But I think I need another different kind for gouges and turning tools?

I've got a new honing wheel to put on there. I think after watching videos I will probably need to order the honing tool for getting the insides of bowl gouges and V carving tools.

Anything else you guys can think of? My first function will be to try to fix some badly marred chisels. Then I'm gonna give some cheap kitchen knives a shot. See how much I can screw things up there before I jump into my skews and bowl gouges and such.

Trying to upload pictures but the system doesn't seem to like photos.
