: Thanks, Todd

I used purple heart in the coaming on my newly finished yak. Both of the vertical part of the striped coaming as well as the laminated lip. Purple heart definitely is a bitch to work dry. It is tough to plane and sand. but besides that it is a fantastic looking wood. i think that it is fairly waterproof also with no treatment from all its natural oils. i would epoxy and varnish it though. seemed to take epoxy and glass and varnish with no problems.

anyways, I was able to bend maybe 2 inch radius curves over 90 degrees if I steamed the wood. more gentle curves like long swooping ones over the full length of a kayak may work okay without steam and heat-. I would make the purple heart strips something like 1/4 the width of the normal strips you are using to get them to bend. getting the bend and twist may be tough so try and use them in flat areas - like cockpit recess, coaming, maybe front and rear deck areas. using them in the hull where the deck swoops up may be a PITA.

good luck and post pictures. I should be posting some pretty soon. the purpleheart will look dull after you cut/sand it.

wipe it with water to see its real color. very pretty.

good luck, Pete czerpak albany, NY
