No never done one, wasnt saying the tower was a waste of time just the temps, at a guess i'd say higher than the roll, or what is says on the tin if going slow, then maybe you can forget about it and devote more time to finding other issues.

Thanks for the advice JamesK. Already tried going out to 3.5mm. That’s why I had to make the new barrel.
Went from only able to print fast and hot to not able to get a print started.
Not only did it get blocked worse, but the wall was so thin it broke the next time I tried to dissemble and unblock.
Had to use left hand threaded tapers to get the bits ob barrel out of hotend and heatblock.
What hotend would you recommend if not the E3D everyone else recommended so far?
I'm still looking for a way to work out if my filament is bad. Got no good filament to compare and likely wont be getting any unless I can confirm this stuff is bad How do I test it??

So just to re-confirm JamesK. No Teflon/PTFE insert in your home made barrel or anywhere below the extruder/bowden line?

I think I may have solved it.
My barrel runs hotter when the filament slows down. I'm sure I have tried more air before, but maybe without the air flow guide.
I couldn't turn air up before and maintain nozzle temps past 180c.
Turning up the min fan speed has made a noticeable difference between two prints.

I like the E3D design because it brings lots of cooling to the heat break where it's needed, without spilling air on the print. Combine that with a well directed and separately controlled print cooling nozzle and you have good control over the cooling side of the equation.
