How to steam bend wooden boat frames

Sharing buttons:

I'm at the stoppage side of this little

twelve-and-a-half at the forward

bulkhead and this is going to be the

first frame that we're going to replace

in the boat now most of the framing from

here backs already been replaced these

frames are actually square edged so

they're square frames and they're put

down they're twisted into place and

that's okay but for the frame that we're

going to put in we're going to saw it to

a progressive bevel or a rolling bevel

and the reason why we're going to do

that is so that it will lay against a

plank and perfectly but the after face

of it will also lay against the bulkhead

I've transferred the degrees from the

inside of the boat onto a very light

little batten and then what I've done is

taken the batten and laid it on this

piece of wooden transferred the numbers

from the batten under the piece of wood

now I've got eight degrees here nine 10

11 12

goes up to 15 degrees I'm going to saw

that rolling bevel right here on a

little portable bandsaw alright we

feeding that frame right through the

bandsaw there now and you can see that

on glancing back and forth from the

numbers on the frame to the numbers on

the bandsaw so that I can keep the two

coinciding with each other so we've

pushed it right through there now

there's our frame I'm going to take it

over to a table here and clamp it down

and just take a little block plane and

plane that roughness off there that the

bandsaw has left no it's come out very

nicely now we're going to go over to a

steam box now I have a steam box but

it's considerably bigger and this just

steams it up much faster because it's

got a very small amount of space in it

this plastic works fantastic it cost no

money whatsoever I haven't invested any

money in materials it's got some

particular advantages that a steam box

doesn't have I can actually put my

fingers on the top of the bag while it's

steaming and feel the frame to see how

limber it's getting as I steam along

that way I can determine if it's ready


it's already remember it's like that

when I do pull it out I'm actually going

to pull it into a piece of pipe

installation so we can deliver it and

it's not going to lose its temperature

right away and we can handle it much

easier now that we've delivered the

frame into position we slide it down out

of the pipe insulation as quickly as we

can because it's cooling off very

rapidly it's a small piece so we bend it

into position and then we fasten it in

with sheetrock screws actually once

we've drilled a hole and we use fender

washers because the planking is so

delicate that what we want to do is

fasten it down into position very

rapidly and then later on we'll replace

those screws with bronze screws and

we've tied the head of the frame over

with a piece of line and the idea of

that is so that it will stay into

position once it's cooled off because

the boat itself is not trained in the

head to very well so that's the idea
