metal & lathe process question (newbie)

[JEK5019]

what about the joining of metal & wood? is there an adhesive you can recommend that would work for both materials and stand up to abuse from the dishwasher?

That's quite a tough one in my experience, not only do you need an adhesive that will stand the temperature and cleaning agents in the dishwasher, but there's the differential expansion between the wood and metal due to temperature and moisture. I remember doing a repair on a wooden handled kitchen implement using epoxy and it lasted about 18 months of semi-regular use, but then parted from the metal. A phenolic adhesive might be your best bet, though the good resins need heat to cure them. And make sure you're using a type of wood that doesn't absorb moisture too readily (likely a very close grained hardwood). Or use the little brass rivet things - there's probably a good reason why they're popular

thanks voicecoil -

good info.. yea - makes sense regarding the varying temps - something to keep in mind.

as far as those rivets go - i've already looked into that. metal inserts like these...

i've watched a few videos where an epoxy is applied - but again - these videos are not for knifes generally tossed into the dishwasher. as the wood to metal alone isn't enough - eventaully the water and temparutre will probably make the wood bend/bow from the metal.

i think i need to source a shop that's produced work for a high kitchen knife maker - as their seams are spot on & beautiful. like the attached. and i imagine some consumers will use them in a dishwasher - though it's not recommended.

The joins are only perfect when new.

The wood eventually moves and gaps/cracks do open up, but they get filled with dirt/grime while being used/washed, which gets hidden by using dark wood.

My mum has a wooden handled set of knifes that must be over 40 year old, and you don't want to look too closely at the handles if dirt upsets you!

yea - that makes sense. it seems most wood handles for kitchen knives happen to be dark. guess i'll stick with dark wood.

thanks.
