Hi,

I bought some new kite sheets the other day in this new rope called evo taper, its basically a triple core rope the outer core is 8mm the middle one is 6mm ad the inner one is 4mm.

Does anyone know the best way of securing each diameter of rope to the next one?

Thanks
Jamie

I think you mean Marlow Excel Taper, I imagine that the best way is to strip away the outer cover to where you want it and then whip and tape it...

When I make kite sheets I normally buy the cheapest rope that feels nice in my hands and then splice in a new core using proper d12 which wont fray or snag. Much cheeper than paying to have dyneema all the way through the sheet and a much nicer finished product.

From the Marlow website:

Ideal for jib and spinnaker sheets.

16 Plait Polyester Outer Cover
Excel Racing with Dyneema SK75 Core

High strength, low stretch dinghy control line.
"Excel Racing core provides the strength where the rope isn't handled.
Excel Racing cover can be stripped again to reveal high strength, lightweight Dyneema core.
Easy to taper - simply pull back outer sheath, cut off to required length and sew and whip to centre core."

Electrical heat shrink sleeving is a good thing to protect each taper point. We have it on the Javelin, tried single tapering but the inner of the two sleeves stripped itself off the dyneema core through endless friction of the twinners.

There are nicer ropes, but if you have it already................

The correct way to bury cover into core or another cover is shown in the other thread on Tapered Spin Sheets

http://www.yachtsandyachting.com/forum/forum_posts.asp?TID=11313&PN=2&title=tapered-spinny-sheets

Measure the length of the thickest diameter you need, then whip tightly where you want to finish that thickness.

unbraid the remaining cover of that thickness and bury it with a fid or a pulling fid/bit of welding wire into the next thinner diameter at four different points around the circumference. if the next diameter is tightly braided then you can use a whipping needle.

Pull each of these out at different lengths and that will give you a gradually tapered bury. the more gradual the better.

Do the same for the third diameter too.

Should get a very neat and clean finish

No, I think you'll find that Evo taper is kingfishers competitor to Marlow Excel Taper

From the headline I thought it was some kind of gluey gaffer tape.

Could be something you use to set rally cars on fire?

It is Evo taper, this is a Kingfisher product. That's also the best way to do it, and maybe a stitch through to secure it all.

Yes, you are right, same product really though. Personally I would rather just use a product with a 12 strand dyneema core. Seems silly carrying the weight of a second cover too. The taper will also be neater that way. Providing the core is a good quality it shouldn't snag or fray which is, I imagine, the reason that you would use a "taper" product from either of these brands.

If you want three diameters of taper in the sheet, using two cores can make the thickest part so stiff it won't run through the blocks cleanly.

Possible but to be honest these pre made products are pretty good.
