im adjusting a second hand jib and need to sew on a double bolt rope to go up the furler. 4mm goes up the track and then 6mm to take the tension. I can make my own bolt rope tape but does anyone know of anywhere that sells it?

Most of the bigger lofts will have rolls of it.

Contender in Brookvale NSW

Yeah, it's called "Gemini" luff tape. Not hugely common these days but still available.

Contender are in Mona Vale. They don't seem to carry luff tape.

Do you mean Bainbridge in Brookvale as here?

www.bainbridgeint.com.au/

A search for luff tape on their site brings up 8 articles for Bainbridge International. But not this one which is comprehensive. Superluff.

See the catalogue here - the page on luff tapes says to go to the new sailcloth supplements document - leave this to you I couldn't find it.

Suggest call Bainbridge Brookvale to see if they stock the correct size Superluff, or can get it in.

Gemini seems to be a Hood product - maybe Hood sailmakers Brookvale can help, as mentioned above.

I think I have found a source for it, backup plan is to get some 4mm luff tape and sew in another rope, last option is to make the tape from scratch.

If the source you think has been found turns out to be valid appreciate your letting us all know what this source is. Thanks in advance.

Will be taking some off a sail if you didnt find any.
