SHARPENING PLANNER BLADES

I have a SS planer sharpener that has two handles. I have a conical sanding disk also. Has anyone had any success using both tools? It looks kinda dangerous to use and hate to mess up blades too.
Thanks,
Tom

If the device pictured in this link is what you have I would say that it is not dangerous (if used properly) and that it works very well. I use mine not frequently but whenever required.
Follow the directions! You are not "grinding" new blades.

I ditto Dusty, I have a conical it is great, finer grit and a light touch/pressure on the blades, they need just a touch, then lap the back side on some 400 Wet/dry Aluminum Oxide wet with some liquid, WD 40, ect or some soapy water.

Need some clarification on planer blade sharpener. Does the table have to be tilted 4 degrees or is it built in on the conical sander? Does the fence have to be adjusted also or does it remain parallel with miter slot on table? They talk about removing set screws and tilting and not real clear to me.
What is the best grit to sharpen the planer blades with. 400 on the back side to take burr off.
Thanks,
Tom

Tilt table? YES. But not necessarily 4°. Typically the table is set to 90° to the face of the disk(closer to 3+, not 4).
IIRC the jig sets the blade bevel to 45° relative to the table top.
Tilting the table differently will provide a means of grinding a different bevel angle(if desired).
Rip fence is not altered.
Only 'set screws' I can think of are the blade securing screws.

I am not sure what instructions you have but all of the questions you asked are covered in the instructions I have.
1. No the table does not get tilted.
2. The fence remains parallel to the miter slot.
3. I have no idea what set screws you are talking about. There is no mention of set screws in the instructions I have. As for tilting see 1. above. The instructions I have say in two different places not to tilt the table.
4. My instructions say to use 150 grit Aluminum Oxide paper. SS sells it, P/N 555433.
I will echo what others have said. The sharpening guide works very well and is easy and quick to use. I my opinion it is not at all dangerous. I have had it since it was first introduced and used it many times. The key is very light passes. Unless you have very dull and nicked up blade two passes or three at the most is all that is required. One thing to keep in mind when doing planer blades is to do the same pass on each blade before adjusting the table for the next pass. That way the blades will all stay the same width. It makes reinstalling the blades much easier.

I have never tilted the table with this, and have not seen where that has been even recommended.
Here's what Shopsmith says about it with the Conical Sanding Disk: "Special nylon glides on the back and bottom edges ensure the guide's smooth travel over your Mark 7 or Mark V tabletop and against your rip fence as it holds your Knives at the precise, correct angle while you sharpen them."
The point is the Disk is made at a specific angle, and the tool is designed to provide the correct angle.
Do you have the Shopsmith instructions on use of it?
Don't get too aggressive, just very light passes and you will likely love the results.
Look at where the table is in relation to the tool though in the picture.

Not according to the instructions. They say not to tilt the table in two places. I have always done it with no tilt and it works fine.

Any one want to tell us all what bevel angle is ground with no table tilt?
I understand the intent is to keep it simple.
Realize the mother ship touts the conical disk as having a 4° angle. - Tain't so!!!!
Ok so the bible does say to not tilt. I stand 'corrected'.
However tilting will determine the bevel angle.
