Picture of Electrical Tape Dispencer
Whether you are using electrical tape for building, soldering or just taping things, it's often a pain trying to rip a piece off at the right place, or having to get scissors to cut a straight piece. Not any more! This instructable will show you how to construct an electrical tape dispenser!

Step 1:

Picture of
For this project you will need: Screw driver, tape dispenser, electrical tape, razor blade, Dremmel ® w/ rotating cutting tip, hot glue gun, and a small screw (a little bigger than your screw driver's bit.)

Step 2: Razor blade

First take apart the razor blade.


Measure than snap off correct size.


The razor should measure the same width as the dispenser.

                   
                          *Caution razor blades are sharp*

Step 3: Cutting the slot for the razor

I've highlighted the spot you need to deepen with your Drimmel ®. This will be where the razor will go. 

* Don't cut all the way through, leave just enough room for the razor. * 

Step 5: Hot glue in the razor

Hot glue the razor into the dispenser.

Then put a a bead of hot glue on both sides for extra reinforcement.

Step 8: Finished!!!

Now you can easily tear off the right about of electrical tape you need! 

Hope you enjoyed this instructables. Feel free to share pictures of your finished tape dispenser bellow in the comment box.  
Anyone know how to make a guard for the razor because I'm 13 and accident prone but other than the razor addressing a serious hazard...ouch....it is a really good idea.

I'm trying to think of a use case for this, that makes this a solution worth considering. None of the examples provided at the beginning of the article seem to me to be worth the hazard of having one of these sitting on a bench, in a tool box or in a tool belt. If you need a straight cut, the lost time of reaching over to the place where the scissors are (or the time needed to hunt for them, and put other tools where they belong if they've been moved) seems to me to be a far better investment than worrying about randomly encountering this when looking for something else.

That said, if you want a bench tape dispenser, might I suggest building a proper one holding all of the varieties of tape you use at your bench, and using the cutting edge of an seran wrap, aluminum foil or waxed paper dispenser to cut off the tape where needed? Or even hack saw blades as shown in instructible http://www.instructables.com/id/Multi-Tape-Dispenser/

The issue of course is not that the blade in use is sharp, of course the blade is sharp. The issue is that you've created a shop hazard to address a bad tool discipline issue, without addressing the bad tool discipline, meaning that you'll end up encountering this at some point in ways that are going to be damaging.

I agree wholeheartedly with your comments - this does not address a problem; it creates a hazard.

As it is, I made my own electrical tape dispenser by using a heavy office-type dispenser and leaving the original serrated-edge cutter in place; it works just fine as it is, and no need to endanger my digits with an exposed razor...

Not to be picky, but the blade you are using came out of a box cutter, not a razor. Both are sharp the razor being the sharpest. Very dangerous setup. A better choice would be from the foil wrap box.

It's "Dremel" (not "Drimmel.")

I love this instructable! it is exactly the kind of thing I hope to find when I view this site. If someone is having difficulty drilling the hole with out breaking the brittle plastic (or simply lacks a drill/bit/etc...) I would recommend using an over-sized washer to hold the tape on. Perhaps one made out of plastic or cardboard.

Every single person who is commenting on the razor blade being sharp:

Thank you. We know.

Simple, but elegant. A very nice idea.
I'd reinforce the warning of the posters here
that some type of guard on the blade/cut-off
is advisable.
onemoroni112 months ago
Great idea. I stress the razor blade warning, please be careful. Years ago in litho prepress stripping process using miles of litho tape I did this with the tape dispenser and once in a while someone would use my dispenser and get a nasty cut on their thumb.
Aha, another ex-stripper. I had a tape dispenser like this, too,
with single-edge razor blade for cut-off. But, I put a sign on it --
"Caution, Bites!"

I like your idea, but I'm sure that I'd cut myself on that razor blade eventually. You could make it safer by adding a guard. I would glue a pair of flat plastic pieces at the ends of the blade (perpendicular to the blade) standing about a centimeter taller than the blade does. That would make it harder to inadvertently place your finger on the blade, but still leave it easy to use.

This is such a great idea. Thanks for sharing it. But, with the dispenser now sporting a nice sharp razor blade sticking up so high, it seems to me that it is a serious cut just waiting to happen.

Haha, nice one! I always mess with the tape. I don't know why I didn't think about this before. Cool!

jI first was looking at the picture for an electrical system of dispensing tape. (Duh!) Finally "got it" looking at your explanation. Good idea!

This is great! I also hate when I have to look for scissors or a blade to cut the tape piece off. It just so happen that I saw an empty tape dispenser in my drawer the other day so I can make one of these. I have a suggestion on how hold the electrical tape in place without using a screw. If you get a piece of flat cardboard and draw two circles one larger than the other one like a doughnut. The inside diameter in the size of the original tape dispenser hole and the outside diameter larger than the black tapes hole then cut out the holes and slip it over the dispensers hole to hold the electrical tape in place.

This is neat! I think I will have to make one for my electrical tape.
