The best funnel I have found to use are from a doctors office. The ones that fit on an exam tool to look in the ears or what ever. So far I have several and they come in two different sizes and work great. I drilled a small hole in the flange at top and attached it to the power horn. I have another appointment with one this month and good thing is the head nurse there is my niece so I will see about getting a box of these and can send some out if anyone is interested in them.
