Chefster.Gavin at pole doctor converts your dolly butt sections into square sections, got to make life so much easier fishing long ...£35 plus £15 postage here’s mine .
How did they achieve the finished result?
Have you lost any length on the section. Is there a spigot joint at the point where it goes from round to flat or has it been built up?
It looks pretty level looking at the picture with no taper to the flat part.
And is it flat on just one side only?
