We never think about leaving our poles in the van during hot weather, this is what's happened to me.
The top section was starting to spin and the clamp was as tight as I can now get it. I took out the top section and cleaned it, then I placed one layer of tape to replace the worn original tape. I have been using the pole like this for months.
I came to open the pole the other day and the top section won't move. All I can think of is that by leaving the pole in the car during the recent hot spell, the glue on the adhesive tape has melted and stuck the two sections together inside.
My next plan is to get the hot air gun on it to see if I can pull the section out, failing that plenty of WD40 to disolve the tape adhesive. I am talking about bog standard electrical tape.
Anyone else had this problem, and how did you seperate the sections?
