Chapter One

Assembling the bulkhead former, keel and stem

I purchased the USF Confederacy kit nearly four years ago. Now that I've gotten a few projects off my desk, I decided it was time to get started. If you've read through any Confederacy build logs, you'll find my comments on the kit likely sound familiar. I welcome critiques of my work as I consider myself a novice at best and appreciate any areas for improvement. The only model I've actually finished was the Bluenose II in 1994, over 30 years ago!

Initial disappointments:

• The bulkhead former and some of the bulkheads were quite warped. I tried to remove the most egregious warps by steaming and weighting with some success.
• Many of the laser cut parts (so far) seem to have been cut with the laser not perpendicular to the board's surface. I don't know if this was a slight misalignment of the laser, the boards being slightly warped when cut, debris preventing the board from sitting flat, or something else. I first noticed this when assembling the stem and while the parts fit nicely on one side, the other side revealed large gaps.
• The curvature of the stem does not match the curve of the bulkhead former.

I completed the stem using wood glue and black tissue paper. I have not applied any stain or sealer yet.



To get the pieces to fit together nicely, I used a table-mounted disk sander on the flat edges and a rotary tool mounted vertically for the curved edges. I laid the pieces flat on the wooden block adjacent to the drum and lightly sanded until the char was nearly gone. This resulted in all of the pieces having flat edges at right angles to their faces. I assembled the stem while temporarily attached to the bulkhead former but removed it and put it aside to keep it from becoming damaged.



For the scarf joint, I used bamboo. I tried some bamboo skewers but they nearly disintegrated in the draw plate. My best success was from cheap bamboo plant supports. It slices cleanly and makes great tree nails. I used a #69 drill bit for the holes and a draw plate to make the nails. The nails measure 0.70 mm. I drilled all the way through and used eight long nails. The material between the keel pieces and between the keel and false keel is black tissue paper.



So far I'm enjoying the build. Despite some of the initial material disappointments, the kit is going together nicely.

Impressive joinery, Philip. I'll pull up a chair.

Thanks Werner!

Impressive joinery, Philip. I'll pull up a chair.

Thanks Paul. My first attempt at the stem was dismal due to my not noticing the slightly angled laser cuts. Lesson learned. I requested a replacement part and the second attempt was much better. I very much appreciate Model Shipways' replacement policy!

Chapter Two

Bulkheads, Fillers, and Basswood Bow Blocks

I bought a HobbyZone Professional Building Slip. I was ready to build my own but for $100 including shipping, it was an easier route. Several of the nuts have been replaced with wing nuts from the original design but the functionality remains the same. I also bought an aerosol can of water-based poly to protect the MDF. For me, the slip was well worth the price.

I use thin planks on the fore and aft clamps to keep from deforming the MDF more than necessary. I also used some small square timbers above the keel clamp to raise the bulkhead former enough for the frames clear the clamp (because I removed the stem and keel assembly).

(My neglected USS Constitution cross section model sits in the background until I decide how to address the red paint I thought I would like but didn't.)



The slip made it easy to check that the frames were square to the bulkhead former.



I also added bow fillers because I'm having trouble visualizing the fairing here. I faired the bow leaving the BFDs and aft edge of frame G untouched. I think I'm getting close?



Even with the fillers, the frames still had enough warp that I used some basswood block to cut braces to fit between each of the frames. I started from the bow working back and the stern working forward always measuring from the same point at the bow and stern respectively so there was no accumulating error. Some slight sanding and shimming of the braces and all of the frames' outer edges are now within ~0.5 mm of the frames' center.

I'll remove the temporary braces when the sweep ports go in. Had I given it more thought, I should have just completed the sweep ports now and saved the extra work.
