Help with bending wood


Recommended Posts

Hello:

 

I'm working on Latina Sanson tug.

 

There is a piece of wood at stern that will need to bend to fit along deck/ grating.

 

First photo shows a sample piece of card stock taken from actual piece in question as it exists before bending.

 

Second photo shows same card stock as it has been taped in place to show how it will end up.

 

The actual wood piece appears to be laminated wood about 2mm thick.

 

Your help please as to how to bend wood.

 

Thank you

 

Rick

Sir;

I too am working on the Sanson model.

I tripped over your query and thought I would offer my method and experience.

I am a big believer in the "Ammonia-soak" method of bending wood.

Essentially, take the piece that you want to bend and submerge it in Ammonia for a couple of hours.

When the piece is well saturated with the Ammonia, take it out and gently bend it to the shape you want.

Set it up with clamps or a mold and let it dry. It'll dry fairly quickly ( a few hours) and hold the very closely to the shape you set when you set up for the drying process.

 

Y/t,

 

Hugh

 

PS: No drafting table, no cutting, no filling and no sanding.

The wood of the piece will look just like it did before the soaking and bending and drying.

The pickle jar lid in #2 is simply intended to keep the wood submerged for the soak.

Although there might be many ways to skin this cat trying it with the part is not one of them. Anytime I run into a difficult task I experiment with something other then the part first. With laser cut kit parts there is always plenty of unused wood on the same sheet.

For LA Don:

Sir;

Having done a number of “plank-on-frame” pieces I have developed a couple of “tips” for builders.

The first problem that can emerge is a bowed keel (piece #1). This was the case with part #1 of Sanson.
My solution is to align two or four (or maybe more) “filets” on either side of where the keel assembly will meet the deck to position the keel along the centerline of the deck;
one on each side of course .Pieces  for these little fillets can be taken from any of the "right angles" of the parts sheets;There are plenty of those.

The second problem I have previously had with “plank-on-frame” models is that sometimes the frames slip out of a 90 degree relationship with the keel.
 I have cemented some small (scrap) pieces of “1/4 round” on the the keel and each frame to hold the 90 degree positioning; (It make me feel better anyway). 

I will try to attach a photo of a sample section of the hull (keel and frame assembly).

Second item (maybe a note to builders): On my current Sanson, I would perform step #11 before starting on step #4.  It may preclude any damage to “upper-works” and deck during what can be some rough handling  during procedure 11.

 

I'm going to try and attach a photo.

Hugh,

 

See my posts above.  You're limited on both file size and the pixel size (length and width).   Try to get below 2M on the file size and keep the pixel acreage at less than 1200 X 1600.

Reducing the size of a jpg.  Most of the photo editing programs have processes to reduce image size.  I use photoshop elements and it only takes a few seconds.  I am sure other members can suggest other software if you don't have elements.
