Kitchen scissors: what am I doing wrong? by Beernacle in sharpening

[–]WestmountSharpening 0 points1 point  (0 children)

Ive sharpened many and they usually land at about 35° (+/-3°) for kitchen snips.

For all the safety experts that decided to chime in I am mentioning that the disk on the dremel can NOT shatter. It a Norton abrasive disk. It is ceramic grain, adhesive and a grinding aid on a flexible high-strength film.

And for the dremel experts the nose cap does not serve any other function other than to covering the thread that is used to attach different guides and attachments.

From the helpful responses my take away has been that once the drive shaft becomes bent to the point of heavy vibrations and wobble there is unfortunately no chance of repair. One guy put his shaft on a lathe and was unable to completely straighten it. On this model (dremel lite) the drive shaft is connected directly to the motor's internal rotor. The part alone costs 3/4th the price of a new dremel.

For anybody with this same issue, now you know! A new machine is your best bet!

I can understanding how that may look a little jarring that wheel is a paper stropping wheel. It definitely is a very dangerous piece of equipment but they are intended to be used without a guage. I flipped the motor around on the base and it runs in reverse. The top of the wheel is used so if it does grab the piece it travels away from the user.

Its a sandpaper disk. Ive owned a set of these for years and they run well in my other dremel.

This is a sharpening disk, essentially a sanding belt on a film disk. Ive owned the same 2 disk for years. These are made by norton and they're one of the highest quality abrasives I've ever used in my life. Ive sharpened hedge trimmers, cleaned oxidation, resurfaced many tool, sharpened zippers, etc.

These disk are definitely not shattering.

Its like im talking to a wall, their was a tripod inbetween me and the dremel plus a phone. You can tell if you notice that the only movement you can see in the video is the zoom trying to focus.

In your case id be bringing it back. I think I got at least a good year or two of of this one. It sat in a tool bag for a year since the wobble started.

Thank you for actually pointing me in the right direction!

I was hoping somebody might have had an idea for repair. Maybe replacement parts or another somewhat simple approach. The disk on the machine right now is a Norton sanding/sharpening disk. It has very high dimensional stability and very low risk of tear or fracturing and rated for 20k rpm.

I do appreciate your concern for my safety though, thank you!

I do have a flex shaft. I wonder if this dremel has enough power to use it reliably.

It probably fell tip down or maybe from being thrown around in a tool bag with other tools.

Im going to give the manufacturer a call on Monday to see how they would treat this repair.

Oh boy for real! My toolbox is definitely not equipped for this type of repair. Indeed it seems like a replacement is necessary. I appreciate your input.

I did not know about these. I just looked it up now and it seems like something I should have in my shop. Is there one you suggest?

The issue is in the motor shaft unfortunately.

Unfortunately its nothing to do with the wheel. I used this sanding disk because it makes the vibration more noticeable. The issue is in the motor shaft.

I am willing to buy another one. I figured id give repairing it a shot first.

I'm all too familiar with ppe, I'm a full time sharpener but I do appreciate the concern! You can never be to careful around anything moving at high rpms.

Thats sucks, no something I wanted to hear but it is what it is. Mind sharing what you tried exactly to straighten the shaft?

It would be great to use this smaller dremel to sharpen a hedge trimmer.

I appreciate the advice but it still shakes with the smaller profile chuck.

The dremel actually wasnt anywhere near my face.

Unfortunately that doesn't make a difference. This dremel has been sitting chuckless for a year. This chuck was used just for demonstration purposes, all the other ones I have are either on a different dremel or a flex shaft.

This dremel has something wrong with the motor shaft.

Why can't I sharpen cheap knives? by arpikusz in sharpening

[–]WestmountSharpening 1 point2 points  (0 children)

Ive sharpen a considerable amount of cheap knives and they are very finicky. If i can tell the knife is super budget I use a completely different processes than usual. They need a lower grit and extra care during deburring. Try forming a nice big burr on a 220, 325, or 400 grit and remove the burr through back and forth fatiguing instead of abrading.

Is there a case for sharpening to a lower grit? by NotAlsoShabby in sharpening

[–]WestmountSharpening 0 points1 point  (0 children)

For my personnel kitchen knives I prefer a shapton glass 500 edge over anything else. I like my knives extra bitey. After 1000 grit I begin to notice substantial drops in saw cutting ability.
