Man sollte gerade so viel Kleber verwendet haben, daß er seitlich nicht herausquillt - dh. der Hamster sollte nicht an den Kleber drankommen (Bild 10).
|10: Kleber sollte nicht hervorquellen / glue should not overflow|
Nach wenigen Sekunden ist der Heißkleber abgekühlt und das Rad schon betriebsbereit.

Today a little tip for owners of wheel-peeing dwarf hamsters. I own several dwarf hamsters myself and some of them pee a lot(!) in their wheels. I offer 20cm Karlie Wonderland wooden wheels because they have a ball bearing and are very silent. They are also available cheaper than other wooden wheels eg. from zooplus.co.uk. I tried to protect them with child-safe paint (Euro Norm EN 71-3) but if your dwarf pees excessively (eg. a diabetic) then this will not withstand the urine forever. So after a year of use some of the wheels were stinky. I then hit on this idea of making a pee-resistent but super-silent wheel cheaply.
Pic 1 shows the Wonderland wheel after 1 year of use as a hamster toilet. The first thing you have to do is to separate the running "bowl" from the stand. We used a saw with a blade that was longer than the wheel's diameter. Saw as near to the back of the wheel as you can (pics 2 and 3). You only have to saw about 1cm deep into the wood, then you can separate the bowl from the stand.
You are then left with the stand and the ball-bearing in a wooden "enclosure" (pic 4). The blue arrow points to the ball-bearing, the red to the axle. The axle is connected to the vertical strut of the stand.
I then replaced the running bowl with a plastic runnung bowl I took from a new Karlie Willy Wheel (pic 5). In the UK and US a wheel identical in construction is sold under the name "Superpet Comfort Wheel" (eg. on amazon.co.uk or amazon.com) which is cheap and pee-resistant but unfortunately does not have a ball-bearing and is therefore a lot more noisy. So what I did was combine the bowl from the Comfort Wheel with the stand and ball-bearing of my old Karlie Wonderlands. You need the 21cm / 8.5in Comfort Wheel to fit on the Wonderland 20cm stand.
Remove the bowl from the Comfort Wheel by squeezing the front part of the axle and sliding the bowl off (pic 6).
Make markings on the back of the bowl - 2.5cm (~1in) from the middle of the wheel (= a 5cm / ~2in diameter) - these will guide you when you glue the stand to the bowl (pic 7).
Apply hot glue to the wooden "housing" of the ball-bearing. Be careful not to use too much or it might get into the ball bearing or overflow on the side later (pic 8).
Immediately after applying the hot glue attach it to the back of the bowl (pic 9). Take care to stay within the markings and that the stand does not hang crookedly. Otherwise the wheel will be off center or crooked and wobble when turned.
The glue should not overflow - the hamster should not have access to it (pic 10). After a few seconds the glue will have cooled and your new wheels are ready to use (pic 11). Voilà, super-silent pee-resistant easily cleanable "Frankenstein" wheels!
