I wanted to add a variation I did after buying the canning tongs and pipe insulation. As many have noted it’s hard to get the rollers to hold the sides of the penis properly without having the shaft twist as you’re applying pressure and pulling them toward the glans. I’ve seen guys complaining about this and even giving preference to the $100 “professional” model because the homemade doesn’t have this concave effect.
I fixed this issue pretty easily by replacing the duct tape on the rollers with 1” wide two-sided tape strips to build up the outer edges while leaving the center concaved.
Get your two sided tape and cut 4 strips that are around 6 inches in length. “Roll” these strips lengthwise around the very outer edges of the rollers. You can stop right here and put the pipe insulation around the rollers (the rollers on my Starfrit model are around 3 inches wide), and this should give you a nice taper toward the center that will hold the penis in the middle of the roller better.
I went the extra mile and put a strip of two-sided tape in the very middle of the roller to keep the foam in place better and potentially make it last longer, but only enough to do a complete revolution of the roller with no overlap.
I'm consistent in spurts, but gains are undeniable!
