Building the Dumas Jenny Lee

Dumas recently released the Jenny Lee Southern Tug. The kit isn't exactly a scale model of any specific boat, but is a type common to the region and era. Having seen the p-type the last visit with the Guys at Dumas, it's not one that I could pass on when the oppertunity came up to do the review.

The model is 24" long with a 7 1/4" beam, done in 1:32 scale. The kit is coplete with laser cut ply, dye cut Sintra, and lots of balsa and bass strip wood. The plans are done in a single full size General Arrangement drawing along with the typical step-by-step instructions and detail drawings.

The hull is of the plank on frame type, rrequiring the keel and each of the 8 hull frames to be built up from laser cut components and strip wood. Nothing complicated here, but is without a doubt a builders kit. The model will be powered with a 370 - 400 class low KV outrunner and a 2S Lipo and a mid sized servo controling the rudder. Then once it's all done, I have a plan to do a few mods -- just for the pure fun of it. So, you'll have to see the whole build through, then we'll get down to the real fun.

So let's get started. . . . .

Building Begins with the Display Stand

The display Stand is built up from dye cut Sintra frames and strip bass wood. All of the components were cut to size, then assembled per the instructions.

Building the Keel

The keel is built up fromlaser cut lite ply and a bas wood strip. The forward and aft sections were built up, then assembled over the detail assembly drawing. The stuffing box is an integral part of the keel assembly, so you'll need the drive parts to get started. The majot assembly was done using Cya, then 5 minute epoxy was used to secure the stuffing box into the aft section.

Building Up the Hull Frames

The hull frames were built up using the laser cut ply halves and a bass wood spreader across the top. Supporting legs are also glued in place to keep things straight and true during the assembly process.

Assembling the Hull Frame

Kit supplied jigs are used to set up the keel for the major assembly process. The front and rear supports were made up from Artists Foam Board using the kit supplied patterns.

As a point of interest; the frame drawings didn'y quite match the dimensions provided for each of the spreaders. Trust the dinensions when the frames are built., as the copies can vary some. Doing that, each of the frames came out in good shape and fit the sheers as they should have.

With the keel in place on the building board, each of the frames were fitted onto the keel. All of the frame notches required a bit of trimming to allow the feet to set flush on the board. Then with all of the frames in place the sheers were built up and glued in place to complete the basic frame.

Setting Up the Deck Details

The Sintra deck was scribed with the wood planking using a machinists scribing tool. When all the planks were scribed, nails were added to add to the overal appeal of the model.

Fitting the Deck and Adding the Bulwark

The deck was glued in place and clamped untill it had dried. The bullwarks were fitted and glued in place next. At this point, with the exception of a bit of filling at the joints on the bulwarks, the hull is ready to plank.

Getting Started on the Planking

The planking is going on per the instructions. The first 5 on each side are laid at the keel. Being as the bend between frames 5 & 6 proved to be a problem making the curve without breaking the planks I used a plank bender to coax the wood around the arc. So far so good.

The next 6 per side will go in starting at the deck and work downward, then after that each remaining section will have to be hand fit.

Continuing on Through the Planking Process

The remaining planks went on without a hitch. I followed the recommended sequence for all but the first from last, and found it easiest to lay it against the bottom plank which was much straighter, requiring less bending as the plank went in. Then the last plank was shaped to fill the remaining gap.

As planking a tug style hull goes, this is no doubt one of the easiest I've done so far. A bender was used where the curves were a little tight, but for the most part everything went in easily
