“Friction tape”“Friction tape”.the flexible cloth semi-sticky tape was standard when wiring residential homes near Detroit in the post WW2 period. Probably left over from the 30's. The house I grew up within had friction tape, rubber tube, and my favorite bare "knob and tube" wiring in the ceiling of our basement. And that tube, while not connected to a load, was hot! "See, I can reach this tubing from the concrete basement floor by standing on my toes" was my comment. My dad had it deenergized and my mom used it as a spare clothesline. Just a few years later I was prying 5U4G's and such from stripped down tv set chassis. I did not use friction tape with my project, although my dad kept some around. 73! Mark K9TR |

"Friction tape"? Sounds similar to hockey tape. Guaranteed to improve your slap shot!
For you old gaffers out there... 73 de va3rr |

The last time I used friction tape was earlier this year. One of our
house rabbits liked to jump between the top of her pen, a low-profile wine cooler, and a large horizontal freezer chest. The wine cooler was very slippery and needed some visible AND friction assistance so that little Houdini wouldn't slide off onto the floor and break her neck. You can file this in the same folder as the cats that like to sleep on top of vintage transceivers because they were warm ... and then they'd accidentally tinkle. Well, those cats always had a silly habit of doing it again, out of spite. After that they stayed out of the ham shack forever, no matter how cold the house got. 73 Jim N6OTQ On Wed, Nov 30, 2022 at 4:45 AM David Wilcox K8WPE via groups.io <Djwilcox01@...> wrote:

“Friction tape”? I haven’t heard that term since high school athletics….back in 1960 or so. It might be similar. I remember it had a weak adhesive compared to duct tape or electricians tape. I never used it for anything but wrapping weak ankle or knee joints back then, especially ankles for ice skating. Dave K8WPE David J.

Is that what we used to call 'friction tape'?

Plumbers tape aka teflon joint tape, thin stretchable non adhesive teflon tape.
Gaffers tape in in the same realm as Duct tap and 200mph tape. Very strong and much thicker than teflon tape and very suitable for any core especially the small ones. Depending on the care and purpose the need for it rare. For cases where higher power is in use or some core types are conductive then glass fiber tape is used. THe cores that need that typically 1.3 inches and larger. Allison ------------------ Post online only, please no email. |

Lighting stores will have gaffer's tape in white as well. It is often used to mark temporary assignments (of cables or dimmers). Sharpie works really well on it.

Your local music store may sell Gaffer's tape - you do not want lots of cords floating around on stage!! Lee KX4TT Jazz is not dead - it merely smells funny!

Micro Center sells gaffer tape; they stock it in black and chroma green. My local store has both in stock. I looked at the Home Depot site. They sell it but it's a ship-to-store or to-home item, and their price is high. There are better places to get it shipped from; I'd probably order it from B&H or Amazon if I were going to get some shipped to me.

That is the only “plumbers” tape I am familiar with, the white very thin stretchable tape for sealing water leaks in a threaded joint. I am not familiar with any other variety. I just keep a spool of the white stuff in my workshop for many applications, not just plumbing. I will look at the other varieties when I go to a big box store next time.
