Sharpening Machine / Jig part 1

I've been working on this Jig for quite a while now, about 2 months perhaps. I got to say that I'm very pleased with the final results, even thought there still some minor flaws that I need to complete (but I feel that the main part is ready to be shared)

This jig was published on Shopnotes #107 just in case anyone would like to try to build this one too. I already tried on my drill press and works like a charm.

I hope by this weekend to be able to add some kind of finish, the abrasive paper, angle gauge and the clamp block. I'll be posting more information as I keep moving forward.

90% of the Jig is made of plywood 3/4", the disks (8 in total, just 2 showing) are MDF 3/4" the pivot arm and the pivot block are maple 3/4"

There's a star knob on the right side, its only use is to adjust the link belt tension.

This is the list of the assembly hardware list

1) 1/2" dia. x 36" precision steel rod
1) 3/16" dia. x 6" steel rod
1) 1/2" I.D. x 15/16" O.D. thrust bearing
2) 1/2" washers
4) 1/2" I.D. x 3/4" O.D. 3/4" sleeve bearing
5) 1/2" steel washers
2) 1/2" I.D. stop collars
2) 3" O.D. pulley with 1/2" bore
1) 5/16"-18 star knob
1) 5/16"-18 3" carriage bolt
1) 5/16" washer
1) 1/2" wide x 36" link belt

If someone wants to give it a try I'll be happy to help you, with sketches or any other necessary information.

Keep in mind that the precision steel rod its extremely hard. I tried with no luck to drill the holes, lucky me I work on a machine shop, so I just spoke with one of the machinist and he gladly help me to drill those holes precisely.

Very nice. Now if I only had a drill press.

Hm.. could just be me but I'm trying to figure out what this is. I know it's a sharpening machine but like nothing I've seen. Can you describe what the disks, cams, rods etc. do? I can't figure out how you'd sharpen with it. Sandpaper on the spinning disks? What's the rod do? I'm a bit clueless here.

I also like to make jigs. This is very well done. Your box joint jig is also impressive.

@ Craftsman on the lake

Yes, I need to add some different grits of sandpaper to the spinning disks. I made several disks (8 in total) for multiple sandpaper grits; the horizontal rod is where you will rest the chisel, blade etc with the clamp block. The vertical rod will get engaged on the drill press and transfer the spinning motion to the disks. I'll try to make a simple sketch to make this easier to understand.

Thanks

interesting idea. i may be missing it - is there a fixture to hold the workpiece at a fixed and reproducible angle?

Yes, there's is a clamp block to hold the workpiece on the angle desired. I will post more pics once I apply some finish to jig.

This is the list of the assembly hardware list

1) 1/2" dia. x 36" precision steel rod
1) 3/16" dia. x 6" steel rod
1) 1/2" I.D. x 15/16" O.D. thrust bearing
2) 1/2" washers
4) 1/2" I.D. x 3/4" O.D. 3/4" sleeve bearing
5) 1/2" steel washers
2) 1/2" I.D. stop collars
2) 3" O.D. pulley with 1/2" bore
1) 5/16"-18 star knob
1) 5/16"-18 3" carriage bolt
1) 5/16" washer
1) 1/2" wide x 36" link belt

If someone wants to give it a try I'll be happy to help you, with sketches or any other necessary information.

Keep in mind that the precision steel rod its extremely hard. I tried with no luck to drill the holes, lucky me I work on a machine shop, so I just spoke with one of the machinist and he gladly help me to drill those holes precisely.
Bought every magazine on woooworking I could find while on vacation in Oregon in early September. Included the Shopnotes with this project in it.

I looked at that article closely, just out of curiosity. They said it was easy to make. I chuckled. I was not interested in making it, just interested in how they did it. It seemed about as simple as…....my switch for my table saw project (-: (see my blog) The advantage, they did tell you how to make it, no design required. But the resulting jig looked very usable and practical. Be sure to give us the lowdown on how it works out.

Sharpening Machine / Jig part 1

I've been working on this Jig for quite a while now, about 2 months perhaps. I got to say that I'm very pleased with the final results, even thought there still some minor flaws that I need to complete (but I feel that the main part is ready to be shared)

This jig was published on Shopnotes #107 just in case anyone would like to try to build this one too. I already tried on my drill press and works like a charm.

I hope by this weekend to be able to add some kind of finish, the abrasive paper, angle gauge and the clamp block. I'll be posting more information as I keep moving forward.

90% of the Jig is made of plywood 3/4", the disks (8 in total, just 2 showing) are MDF 3/4" the pivot arm and the pivot block are maple 3/4"

There's a star knob on the right side, its only use is to adjust the link belt tension.

A shot from the bottom of the jig shows you the link belt

Once the bushings are installed and secured with epoxy, sanded them flush to the plywood

Heres is were the 2 disks will be sitting in top of a thrust bearing

I had added some sketches I just made, it may help you understand how this works

a1Jim Yes this was on shopnotes # 107

I have the Shop Notes issue with this jig. It looks like a great jig and you are doing a great job building it. We woodworkers love stuff like this, but I'm sticking to my diamond stone and quick hand sharpening technique. I just can't see myself setting this big jig on the drillpress every time I want to sharpen a chisel. I'm too old and I don't want to use whatever time I have left with all the bother. Besides, I get a great edge in about 1 or 2 minutes depending on how dull with my simplest way of sharpening. I apologize for being so negative about the really nice work you are doing on this sharpener, but I think these contraptions are leading woodworkers in the wrong direction. I honestly believe you will find it so inconvenient that in the end you will hardly or never actually use it. I do think that it would be great to sharpen a lot of tools at the same time, then it would be worthwhile, but usually this is not the case in a woodworking shop. I hope you don't hate me for my honest opinion on this. I also hope the sharpener delivers what you expect from it.

Adding some finish + angle gage & clamp block

So today I had some free time, I add it some finish to the entire machine, since this is not any kind of furniture at all I decided to to go the hard way, I basically applied some spray paint, the maple parts had some wipe on poly.

I also got the time to add the missing angle gage and the clamp block. All I need now is to get some different sandpaper grits and this baby should be ready to be put to the test.

I will also like to ask a question.

What grits of sandpaper should I get? I do have 8 disks available for 8 different sandpaper grits. what will be the best choice.

Also when will you use the 30 degrees bevel? I know many of the chisels are 20 degrees and the plane blades are 25 but how about the 30. sorry if this is a dumb question. :)

Ok enough interrogation and here are the pics.
