hello people,im new to this and the forum so a big hello from not so sunny england lol.
i have a question regarding the mast support,i know the mast should be able to rotate but wouldnt the tube rub and wear the mast and cause it to fail? i see in the construction plans that people are using non seemless tube? surely the seam will aid in trashing the mast? what other ways are there to allow the mast to rotate but not rub in the tube? best regards,greenE.
