Step 1: Tools & Materials
- Two plastic tubes about the same size as the inner diameter of your pet's boots. (I used extension tubs from an old vacuum cleaner.)
- Two large plastic bottles with screw on lids.
- Two plastic perscription pill bottles, Close in diameter to the plastic tubes.
- Epoxy putty.
- Dremel Trio (or other implements of cutting and drilling).
- Bench vise.
- Utility knife.
- Deburring tool.
- Tape measure.
- Rubber gloves.
- Work piece protectors (optional).
Step 2: Marking & Cutting
I started with the vacuum extensions. Slide a boot onto the tube to serve as a template. Mark where the bottom of the boot reaches. Then
use your tape measure to make a mark two inches below this mark. This is where we will cut the tubes. In order to make the next set of marking easier I made these cuts now. I did this by placing the extensions in my bench vise and cutting it with my Dremel Trio, which I also used to file down the rough edges. In retrospect the cuts would have been cleaner if I had used a hacksaw.
When the cuts are made it is time to lay out the air circulation holes. You can do this in some really precise scientific manner, but I just chose to eyeball it. I just laid out the holes in an alternating fashion to try and distribute the hot air as evenly as possible. I then clamped the vacuum extention into my bench vise and used my Dremel Trio at a low speed to cut the holes. When I cut all the holes in both extentions I used a large file to knock the scrap plastic out of the extensions and smooth the edges of the holes.
With the vacuum extnesions marked I moved onto the bottles that will serve as the bases for the extensions. Turn the bottles so the bottoms are facing up. Using your boot dryer as a template trace the diameter of the boot dryer tube onto the bottle bottoms. With the diameter marked clamp the tops of the bottle in your bench vise and cut out the marked area. Test fit to make sure the cut bottles fit snuggly around the boot dryer tubes
Step 3: Marking & Cutting 2
Cutting the lids was a little tricky as placing the lids in the bench vise secure enough to hold them for cutting would crush them. I solved this by screwing the lids back onto the bottles and then sliding them onto the boot dryer tube which I secured in the bench vise. This gave me a stable surface to work from.
Step 4: Joining
Step 5: Limiting the Flow
I clamped the bottles in my bench vise bottoms facing up. I drilled out the center of bottle bottoms with a 17/64" drill bit. This removed about 1/3 of the material and will (hypothetically) redirect the majority of the air out the sides of the extensions.
With the holes drilled I clamped the bottles horizontally into the bench vise and used my hacksaw to cut the bottoms off the bottles. I then used a utility knife and deburring tool to clean up the edges.
I then pressed these sevred bottoms onto the tops of the extentions. Now we're ready to dry.
