- The Harbor Freight (Central Machinery) 4" x 36" Belt Sander can be an excellent tool sharpening device if equipped with the proper tool stabilization device. Today I am demonstrating a prototype sharpening attachment based on the patented features of the 1970s ProEdge that my father designed for a 1" belt sander. Most of the pieces are 3D printed.
Your dad came up with a great idea and Dave Flora from Shopsmith did a wonderful reverse engineering it from off-the-Shopsmith-shelf components to adapt it to their Strip Sander. Thanks for sharing this tutorial, Jim. Norman was a clever man. Scott
Can you make a video of how to reset the sander table from horizontal to vertical. The Manual does not do much of job with the instructions to get that done. Thank you.
What grit belt did you use? Very well done. I love innovative approaches to tasks. Your dad was a,smart guy.
Do you make, sell, or supply plans for your jig?
I would like to make something like this and was wondering if you could share your stl files for printing?
That's an awesome idea, I'm going to use part of it. But buddy. You need a way less aggressive belt on there. Like, 400-600 minimum for your last stage of sharpening most things. Lathe tools, maybe 200ish is OK. You're on lawnmower setting.
I’ve been production turning for over 40 years. With my experience, it would be a waste of my time to change grits. 30 seconds on a whet stone and the edge is razor sharp. In my opinion.
Anymore videos on this? I like it
Brads Workbench What would you like to see? I’m always up for another video
@@jdplus3 id like to see more of the build/design of it. Or at least the key parts. Im definitely thinking of building this myself
@@jdplus3 how to sharpen tools without jig. I don't have 3D printer. Dont have bunch of stuff laying around to make a jig. In which nobody explains how to make the jig in the first place. How to mount it etc
Nice idea but you really need to show your device better.
Everyone creates a jig. What if you don't have any special stuff laying around to make one? Dang i just need a video on how to sharpen my tools. Don't need one showing how they sharpens one after a jig.
Well I can try to show you that. Thing is most serious turners and carvers really want a very reproducible predictable edge. Otherwise things happen. The tool slips and you cut your non dominant hand. Or the edge catches and destroys your spindle. In your case just get a carbide cutter which you use 4 sides and toss the $16 insert. They last a long time. I use one tip in daily production for months.
@@jdplus3 I have one carbide tip. But it seems to catch really hard at times. And have destroyed a wood and resin project. Tore a huge chunk out. I use my belt sander to sharpen. And I bought a grissley wet grinding system. And has A leather wheel as well. But didn't come with any guides. So I am guessing at angles and of course get no edge. And mostly ruin the edge.
I see many videos saying 45 deg or 30 or 50 deg.
So nothing really works and I don't have a jig. So..how to get a sharp tool
@@donovanbryan8086 I dont know if i consider MYself an expert on sharpening, but in 40 years I have tried to:
1. say close to the edge I originally had on the tool, and
2. have the same edge every time so I know what to expect.
3. angle depends on function. skew chisels have very sharp angles while roughing gouges may be more like the 45 you mention, and bowl gouges are really steep.
4. I ruined about 30 clear casts over a couple of months figuring out my resin for pens.
5. i just ordered a negative rake carbide cutter to try. i suspect the whole benefit of those is that they simply prevent you from taking a deep cut and catching.
6. with resin, i have a great respect and take of thousandths of an inch at a time and i dont work in 1 spot too long thinking i might heat up the resin.
7. maybe think about WHY you are catching. there is a good video on catches out there I watched. it is very true that if your tool is not flat on your tool rest, it will END UP flat on your tool rest after catching. make sure the tool cannot roll. look at how much fulcrum/leverage you have, are you over extended too far past the tool rest. despite what people show in videos, resin is an unforgiving bitch.
@@donovanbryan8086 the Grizzley system looks neat. I would think it would work, and has the ability of a hollow ground edge - great for gouges, (but not a flat ground edge (which i would think would be preferred on skews). another idea, is if you have an edge/angle you like, draw all over the edge with a Sharpie marker and then you can see where you are hitting on the wheel and adjust your angle. my father taught me that in the '70s.
