I am looking for items that we have around the house to use to raise the comb height?? I have used the A/C copper pipe closed cell black foam, but I do not have this any thinner than 3/8' thick. I am looking for something in the 1/8' to 1/4' thickness. I thought about that packing foam...it is probably around 1/8' thick. I know others have done this comb increase...just looking to hear what you have tried that works. Thanks in advance for any tips and ideas. the colonel.
