Splicing

Post by Macko » Tue Jan 03, 2017 4:32 pm

Reading one of Mr Yates books, he breaks the tip of his Avon, and says he'll have to splice the tip.
How do you splice a tip in and is it strong enough afterwards.

splicing is cutting the affected area diagonally across the rod at 4-6° Angle then doing the same too the tip and then gluing them together and clamping them .then you over whip the join with white silk thread in a continues whip then using epoxy seal it the silk thread will go transparent in the epoxy .leave too set.

its a repair and will be sufficient but it'll never be as strong as a new section would be .as a tempery measure even last for extended periods (one of mine still going strong) ,but you'll always know its a patch up and confidence won't be with it ,not like you get with a new section .

I've done a few and find it works better with thinner sections where the load is carried further down I'm not so inclined .

after all all splitcane rods are just strips of wood glued together ,a splice is no different but the angle has too be right or it'll fail under load.

I had visions of maybe splitting the cane down an inch or so and cutting 3 alternate pieces maybe half inch long on the broken
section and the piece to splice, so as they interlock, then overwhipping, if you know what i mean.

you could do that and the same on the other piece you would need too angle the ends of the strips to create a mini splice where they over lap a little .again like the single splice the angle needs too be 3-4° ,but only a few mm long .they use this method too create rods from short strips of different colours creating a parkay pattern

the overlap helps spread load
Image

what you have to avoid if two edges butting up too each other ][ as it'll create a sheer point and break easily ,plus the splice must be 90° to the spine / arc of the blank ,or again it'll create a sheer point

In the uk its simply a splice or graft in the us its called scarf joint or scarfing and they even have special planning blocks to get the angle cut right

Seeing this post on splicing reminded me of a very old rod I had which had joints that you used to have to whip together rather than the usual ferrules. I found this on the net which is like my rod, but mine was greenheart if I remember correctly...

I use nano silk thread ,Nano-Silk-Ultra-Fine-30D-18/0 ,not a bad price either (the blacks nice too for inters etc)

I don't have a particular epoxy varnish that I use ,depending on the varnish used you may need too thin it down so it penetrates better (with acetone [nail varnish remover] ,or denatured alcohol) i'd try a test first as mixing finishes between epoxy and pre existing varnishes may bring unforeseen results ,they don't all play well together . superglue would work but it has too be applied carefully or it'll whiten ! .

not sure (not tried it) but Sally Hansen Hard as Nails ,clear maybe epoxy based ,plus there's a Sally Hansen Hard as Nails thinner/remover to go with it ,these have many uses so might be worth trying .
