HF belt sander sharpening jig

I recently watched a video by Capt Eddie about this method of sharpening my lathe tools. I also saw where Gerry(TheDane) set up his system. This spurred me into going ahead and setting up my sys. I bought the HF belt sander and installed the board on the stop. I drilled out the shallow holes 4 1/4” from belt to support the home made jig I put the tool in. I had previously built the jig to hold the lathe tool and this also came from Capt Eddie. I wanted a different grind on one of my tools so I placed the tool in the jig and placed against the belt at the desired angle. I then drilled 2 more holes in the board at 2 5/16 for this setting. The two holes in the middle of the four close to the belt are where I was trying to find the place and now aren’t used. Also the hole up close to the stop is for another jig and also to put the jig for the lathe tools.

I’m not getting the results on the 45deg setting I wanted and don’t know if it is me or the sys. I ordered the Woodcraft slow grinder and will build the wolverine sys and try that. I needed a better bench grinder anyway so not a wasted purchase if I’m still not satisfied with the results.

I love the Woodcraft Slow 8” Grinder…and would not enjoy turning without a Wolverine jig and it is worth buying!
my friend…flat grinding of lathe tools is not a good idea in my opinion and it seems wrong from everything I know about grinding…read about hollow grinding and also about High Speed Steel vs Carbon Steel I do think you have both in your collection of tools

Dewayne I agree with Cosmicturner, I am by no means an expert on sharpining tools but I feel if you are going to use expensive turning tools at least get a sharpining system that will give your tools the edge they need. I see you have ordered the slow speed grinder from woodcraft thats a great start now go and order the complete wolverine
sharpining jig. I bought this system and am glad I did because I can now sharpin my turning chisels without to
much guess work like I said beleave me I am no expert and I am still learning, but this system does a great job
and well worth the money. I have the Robert Sorby chisels and haven’t ruined them yet ha! ha!.
Good Luck and keep turning and sharing.

Jeff I am new to both sys so I bought the HF sander first as it was the cheapest start up cost. I tried the grinding by hand and I’m not that good at following the contour. Right now I don’t know which is better as I have only tried this sys. I know I am not satisfied with the results I obtained on the 45deg setting with my Sorby tools. I rotate the tool around the axis of the jig from one side to the other. I would like to do the fingernail grind on them but it’s not coming out that way. Gona have to find out how to do it. Maybe can do it on the Slow grinder. I guess time will tell. I have looked at some of the videos and though I was doing it right but maybe not.
Don’t know if the Craftsman tools are carbon steel or not but the newer are HSS.

Bill you beat me on your reply but I see where others got what they wanted with the belt sander and like I said it was the cheapest of the tools I was gona buy anyway. I think one of the grinds is 60deg and it werks fine on those but the 45 leaves a hook on end and not same on both sides. I have the parts bought to make the wolverine already so I will make it soon as I get my grinder.

Hello Dewayne,

It is interesting to read about your try at this setup. I have been looking at doing this too.

I am going to suggest you take a look at Klingspor Abrasive belts (http://www.woodworkingshop.com/abrasive-belts/) and get a belt designed especially for metals. It might help.

Also, I view this type of machine sharpening as really “shaping”. Sharpening to me means finishing using handwork with a super fine diamond lap, then an Arkansas stone, then finally a leather strop charged with jeweler’s rouge. I don’t quit until I can shave the hair off my arm with the tool.

Planeman40 thanks on the headsup on the metal melt I will have to look into that. When I got the shape I wanted on the 60deg tool it would slice right through the turning with one or two passes across the belt. So I am satisfied with how it turns out. My problem is with the outcome with the 45deg tool. I don’t have the patience to do all that you do. Not knocking it but I don’t need it that sharp. I just need to learn how to do the fingernail grind and am hoping the slow speed grinder will get me there. Thanks for the input though.

Nice set up! I opted for the grinder and a home made wolverine.

Planeman, do you turn? If I finished up my chisels the way you describe. I would give up turning quick :). There are times I need to sharpen 3 or 4 different tools multiple times during the same turning.

sharp edge that breaks off is useless to a turner you want a durable correct hollow ground edge for lathe tools….chisels are totally different they are not subjected to the same forces as lathe tools…the curve of the grinding wheel is KEY! And it needs to be 6-8” diameter to achieve the correct hollow ground I am not trying to sell you anything only offering advice?
I can’t see why you would ever want to sand an edge on a turning tool a chisel with 2400 grit emery on a flat stone sure…lathe tools are a totally different than a plane or a chisel that lathe is flying run a 20 foot board in a fraction of a second over a plane edge it will be dull in one pass it will break the sharp edge off
Every revolution of the lathe you go from end grain to face grain twice think about it…knots, voids little stones burls, the non turning guys like straight clear grain wood for reason.
ps
slow speed means nothing with high speed steel and the correct wheel (white, pink, blue, never gray)...the wheel being dressed and balanced is important

I have been much happier with the results I get with the HF belt sander rig than with my Wolverine and WoodCraft slow speed grinder. I don’t see any benefit in having a hollow grind.

The flat grind on the bevel makes it much easier to ride the bevel, and my tools (especially my skews) have never been so sharp. I don’t have to re-sharpen any more often with my belt sander rig than I did with the wolverine, and re-sharpening on the HF rig is much faster.

I use a 150 grit belt, and finish up with a couple of seconds on the buffing wheel with green compound.

Maybe it is just a case of different strokes for different folks!

Gerry The 60deg I wanted on some of my chisels is looking good and werks fine. I don’t know what is wrong but The 45deg I wanted on some of my chisels isn’t coming out right. The sides aren’t even and there is a small sharp point on the center. I have tried several diff things but I can’t get them to come out. They are two diff designs. One set has more of a “V” than the other set which has more of a “U” shape. So that may be what is wrong. I don’t know what else to do except try the grinder. I need a better grinder anyway as I only have a B/D 1/2” x 6” small one. I won’t be wasting money as I needed both the sander and grinder just wasn’t going to buy them so close together.

Dewayne, I did the same as you. I had a craftsman sander just like the HF sander. The wooden block, for some reason isn’t long enough for the 45 degree grind. I changed the wood block and got better results. I do need another grinder and I’m considering the Woodcraft grinder to see how that will work. I’ve already built the Wolverine like setup for my 6” grinder so it will be just a matter of swapping the grinders out.

Thelt you say you changed the wooden block. What did you change it to. I drilled 2 sets of holes in the board the one for the 45deg closer to the wood stop at 2 5/16” from belt and the one for the 60deg was 4.25”.

I got my woodcraft grinder yesterday and got it set up and am in process of building the wolverine jig now. It will be next week some time now before I can finish it though. I hope it werks. I will have to get my son or brother to weld it for me as I don’t have a welder.

LDL, I said I changed the wood block, what I meant is I changed the hole location from what the plan called for.
I matched the angle on the tool with a new hole location and drilled a different hole from what the capt. said.

How close to the belt did you drill your hole. That’s what I did and my hole was 2 5/16 from the belt but it’s not coming out right for some reason. Are you using Capt Eddie’s tool holder jig?

I really didn’t measure it. I just placed the tool where it was sitting flat on the sandpaper, marked it and drilled my hole. Yes, I bought one of Capt Eddies Blackhawk jigs. That’s what I had the gouge in when I made the new hole.
