Nice work.Does it help with the skiving process? Was it worth modifying as I have one similar?

Yes. For me it is much better having the feed speed slower. You can control it much better. Also, the knife can stay at a high speed so it cuts better. In a normal setup if you slow the feed speed you also slow the knife. 

However, the single most important thing I learned about using a skiving machine is this: get the blade very very sharp. Makes a world of a difference! Once you learn to sharpen it correctly you will be amazed at the difference

A skiving machine is very nice to have. Mine is in a building about 10 minutes from our apartment (where we have our small shop). If it was in my shop I would use it daily!

Interesting set up. I was wondering if for the wiring of the two motors, you have them on independent plugs or have both operating off a single plug/controller.

Hi Adam,

can you describe how you sharpen and what you should look out for? Its something I will have to do soon...

Thanks

Many thanks for all the input into this thread. I was looking at modifying my bellskiver and found exactly what I needed here. Just incase it helps anybody out in the future here's a photo of mine. 

 

So what I gather from here is that the feed pulley is connected to the servo and the knife pulley is connected to the clutch motor ?

If so how do you make the clutch motor run continuosly  ?

They both look like servo motors to me, I guess you just lock the controller box a what speed you need.

I'm still looking at doing this mod to my skiver but I'd like to get both motors under the table.

Cool, all the best for your mod !

I have them on independent plugs.

I will try my best to describe it.  I think there are some YouTube videos about sharpening. I do not have access to my skiver at the moment (it is at another location). If I had my machine in front of me, I would do a video to show you or take photos. Unfortunate, because of the coronavirus I can't do that at this time.

To the best of my memory here is how I do it. If anyone else is an expert at this, please post you corrections (I will not get offended!).

Please be careful and watch your fingers and eyes!

How to sharpen knife/blade:
1. Clean your sharpening stone. It will sharpen much easier with a clean stone :). You may need to clean it several times as you sharpen the knife. If there are 0 sparks them you need to clean it.
2. While machine is running (or while you rotate the blade) run a black permeant marker over the edge of the knife (about 10-12mm of the edge). This will show you if/when your knife (blade) is sharp.
3. Position knife at a certain distance from the top guard. OR some other fixed location. For example: I place the blade 10mm to the left of my top knife guard. I use a ruler to check this. I like this position to be where I normally leave my knife. That is, very close (2mm?) from the edge of my presser foot.  EVERY time you sharpen the knife, put the knife in this position. Why? Because this sets the angle of the knife and gives you constancy. You want the knife in a fixed position, and then,
4. Slowly (very carefully!), move the sharpening stone towards the knife. As you sharpen continue to move the stone toward the knife,
5. Stop once the marker is gone. You should have a nice 10mm polished edge that is very sharp. 

As the knife gets dull, you will need to move it back to it's fixed sharpening position and sharpen it a bit, so just a little to the left.

I hope all this makes sense!

Hi, Now that many clones are made there seems to be no information with them when you buy them, this seems to have lost importance for people these days, no diagrams, illustrations, measurements etc..... I would get hold of a user manual for a older machine which the basics will apply, like feet position, sharpening, motor speed etc.... If anyone wants a copy of the Fortuna skiver manual PM me. Also now the skivers are fitted with servos which can be flipped to run in both directions at a push of a button. According to the manual,....REMEMBER:
