Ever get a roll of TP that has the inner cardboard core bent so that it doesn't roll? Often when getting the TP home from the store, the inner core is misshaped, so it doesn't roll very well. This causes you to get only a couple sheets at a time, and usually when you really, really need a lot more.
This will show you how to make it roll much easier, and protect the core from getting crushed during use.
Step 1: Items needed
Toilet paper roll
Since the only kind of TP I use is on Mega-rolls, this will refer to that size. A standard size may differ in the inner and outer diameter, so measure before buying the PVC pipe. Since standard rollers don't have the extensions that the mega-rollers do, you could just cut a length of PVC pipe to size and slide it in. Because the mega-rollers have the extensions, you have to cut a piece for each end.
The cardboard core on a mega-roll is 1 5/8 inches in diameter. Get a short length of PVC pipe that has that outer diameter (measure across the circle, from outside edge to outside edge).
Step 2: Cut two rings.
Saw off two rings, about 1/4 inch wide.
Step 3: Sand.
Sand the rough edges to insure a smooth rolling action. You may want to leave a portion of the inner diameter a little rough to help prevent a runaway roll.
Step 4: Gather items.
You can see the extensions on the mega-roller. This is to accommodate the extra thickness on a Mega Roll that won't fit in most standard TP receptacles. (You only need two rings -- the extra one on the lower right is one I had cut too thin.)
Step 5: Assemble.
Put the roller in first, then hook the rings on each end.
Step 6: Insert rings into core.
Carefully insert the rings into the core on each side.
Step 7: Roll away!!!
This will now allow for easier rolling, and protect the core from getting smashed.
Note: In this household, the paper flap goes to the front. You may have to set it the other way if you have cats. Or an insistent wife.
