How do you change out sanding drum (on mandrel) when sanding drum is worn down?

Jill Timm's class, The Amazing Dremel, into one blog post.
Bwahahahahahahah!!!
I did not take into account how many notes I took during the workshop. In fact, my table neighbor at the workshop teased me for two days on how many notes I took.
My plan is to split the information into three blog posts:

• Dremel bits and what they do (hey - that's what you're reading now!)
• Tips for using a Dremel with specific materials
• Dremel resources for artists

Please note that this post only focuses on what the bits look like and what they do. Oh, and the bits mentioned are the only ones that we used in the workshop - we didn't use any routing bits. Sorry.
That said, let's talk Dremel bits.
I think that one of the things that both attracted me and freaked me out about the Dremel was its huge buffet of accessories. The packages are labeled by use, but it still seemed like gibberish to me. Jill created the perfect environment for overcoming my Dremel fear.
You can read about my class in the following blog posts:

• The Amazing Dremel with Jill Timm - Day 1
• The Amazing Dremel with Jill Timm - Day 2

This post is in no way meant to replace the total awesomeness of taking Jill Timm's class. I benefited so much from hearing Jill's experiences and seeing her work in person. If I had bought a Dremel and experimented with it on my own, most likely I would have never tried it on the range of materials that we did in class.
Jill recently announced that she's taking her Dremel class on the road and would love to be scheduled by your group. I highly recommend the class if you have a chance to attend.
The main categories of bits, according to Dremel, include the following:

1. Carving & Engraving
2. Sanding
3. Cutting
4. Grinding & Sharpening
5. Cleaning & Polishing

These categories are pretty consistent among other manufacturers of rotary tool accessories, so you can often find alternatives if you shop around. Carving & Engraving I used two different types of bits that fall into the carving & engraving category - diamond bits and high speed cutters.
Diamond Dremel bits
Diamond bits can be used with the following materials:

• Aluminum
• Bookboard
• Ceramic tile
• Glass
• Mirror
• Steel

Dremel high speed cutters
High speed cutters can be used with the following materials:

• Bookboard
• Linoleum
• Polymer clay
• Wood

Sanding Sanding involves two different parts - the drum and the sanding band. Sanding bands come in different grits, just like sheets of sandpaper.
Dremel sanding bands and drum
To use the sanding band, you simply slide it over the drum. Replace it when it wears out. Easy peasy.
Sanding bits can be used with the following materials:

• Aluminum
• Bookboard
• Plexiglass
• Polymer clay
• Wood

Cutting There are different types of cutting wheels for different materials.
Abrasive cutting wheels
Abrasive cutting wheels can be used with the following materials:

• Bookboard
• Plexiglass
• Wood

Fiberglass cutting wheel
Fiberglass cutting wheels can be used with the following materials:

• Aluminum
• Bookboard
• Ceramic tile
• Wood

To use a cutting wheel, you have to attach it a mandrel.
Dremel mandrel
Unscrew the tiny screw on top of the mandrel and remove one of the washers.
Slide the wheel onto the screw, then add the second washer. Attach the screw to the mandrel base and tighten.
Replace the wheel it when it wears out.
Grinding & Sharpening Grinding and sharpening stones are made of two basic materials: silicon carbide (green bits) and aluminum oxide (brown, orange, pink, or grey bits). You may have noticed that some of my grinding stones are oddly-shaped. This is because the stones wear out with use. You can reshape your grinding stones using a dressing stone.
Orange grinding stones
Orange stones can be used with the following materials:

• Ceramic tile
• Glass
• Mirror
• Steel

Blue/green & pink grinding stones
Blue/green and pink stones can be used with the following materials:

• Aluminum
• Ceramic tile
• Glass
• Mirror

Cleaning & Polishing Felt polishing wheels and cones are used in combination with polishing compound.
Polishing felts and mandrel
Polishing compound
To use a polishing felt, you have to attach it a mandrel (different from the cutting wheel mandrel). The felt has a tiny hole in the center of it - you screw the mandrel into the hole to attach it.
Felt polishing wheels and cones can be used with the following materials:

• Aluminum
• Ceramic tile
• Glass
• Mirror

As for the stripe, you will need to change the blades, they are worn out, if not damaged outright. As for the cutting the grass lower on one side, since you are changing the blades, remove the deck and inspect the spindle/mandrel on the troublesome side paying close attention to the ears that the bolts that mount it go into, you may well find that one of them is cracked. If so, replace it. The spindle/mandrel cost a little over $60.

I hope this helps you out.

Hello,

Sorry they way to remove a ink stain from the drum (becuase of the heat it's "baked on) is to sand the drum down which will leave raw metal causing the drum to rust
It could be sanded down and repainted but you would need to go to the auto parts store and get some paint for engines since its desiged for high heat

Good luck

unplug tool and while holding the spindle lock loosen the screw in the center of the rubber barrel to reduce the diameter and this make instal/removal easy. don't forget to retighten before using.

remove the deck from the mower, take off the blade, take off the deck drive belt, take out the bolts which hold the mandrel to the deck. put new mandrel in, reverse the whole order. do yourself a favor and take lots of before pictures so you do not have to ask how to put the belts back on. mandrels can be obtained at small engine and mower repair shops. you may just want to replace all of them while you have it apart as they are all the same age and wear.

THE BRAKE ROTORS AND BRAKE DRUMS IS GLAZED NEED EITHER RESURFACED IT NOT WORN DOWN FAR. OR REPLACED.SOMETIMES YOU CAN USE ROUGH GRIT SAND PAPER TO REMOVE GLAZE FOR A WHILE BUT STILL GOING HAVE TO RESURFACE OR REPLACE IN THE LONG RUN.

Take tires off then inspect rear brake shoes if okay and not down to the metal service the drums with sand paper and put them back on you might have to replace the drums and shoes!

possible if you have a drill bit smaller than the screw and you can try drilling in reverse. Might be better just to replace the mandrel though.

Make sure to loosen the screw on the end of the mandrel. After removing the old sanding drum, gently roll the black rubber between your fingers to compress it slightly. The new sanding drum should slide right on and then tighten the screw.

The squeal is usually the tell tales that make a noise when the front or rear disk pads are worn to where they need replacing. However, with drum brakes, that is an indication of totally worn out shoes, or a broken part. STOP driving the car, go to a mechanic (or friend) and have them checked.
