Top pattern on 3/4 in poplar stock. Note arrow showing Grain direction.

Two block hull glue up showing side mount vise holding method. With C-clamp mounted in wood vise. Note 3/4 in spacer beneath hull glue-up.

Note that most of the excess side material has been trimmed away on bandsaw while hull bottom is still flat. Foredeck pattern has been trimmed away.

Showing C-clamp mounting. Note that the ridge at the edge of the c-clamp throat is against the top of wood vise blocks for stability.

Foredeck block in place with side pattern applied. Note that bottom of hull is still flat.

YMS Prototype 1/148 scale; Showing side material removed and both top and side patterns in place.

Block cut to match side patterns. Deck planed using "Stopping Cuts" to make pronounced "SwayBack" deck of the YMS design.
Bottom cut flat with the exception of fantail, which is angled but still flat. Note pattern wrapping around fantail.

Upper For-Deck pattern left on for future drilling and marking of For-Deck structures. Made of two laminations of 1/32 birch plywood.
Note that the part is still slightly larger than the pattern and will be trimmed in finishing.

Hi Ray, need a pic of your mine sweeper. What scale, what brand etc...

Lou

[R.F.Bennett]

Working on the build images Gents. Scale is 1/148th this will be the 1st in the SilverCraft line of plans. SilverCraft is the brand my grandfather built his boats under, about 40 years ago. This prototype is being built to produce patterns that plans will be developed from.

Ray,

Those chips are really flying!  Your YMS is really coming along.

Excellent tutorial for new ship builders.

Ray,

I ran your photos as a slide show ( I love this feature) and it looks great.  I can't wait to see more photos.

I have uploaded the original plans used for my YMS/BYMS project;

Thanks, Ray!

I did some checking, because her line looked familiar, and found that the BYMS-1 (British YMS) class is essentially the same ship.

BYMS-26 became J-826 became BYMS-2026 became the car ferry Calypso, became Jacques Cousteau's ship Calypso.

Oh, and she was built by the by the Ballard Marine Railway Co., Inc., Seattle, WA.

Yes, someday I'd like to do the Calypso version. I have a picture of her from 1958 with the original bridge with the round portholes. John Wayne also bought one to make into his private yacht. You can also see one in "The Life Aquatic" A Bill Murray film from a few years back. As far as I can tell some had an open flying bridge and some had the space just closed in. Perhaps for Atlantic or Pacific service? They were actually built by many different Yacht builders throughout the US.

[R.F.Bennett]

My Mistake, The ship in "The Life Aquatic" was an Australian "Ton" class Sweeper. A good future project.

YMS Build has been updated, Please see the start of this post. It will be continued there as an edit to the post and not a reply. It should be easier to follow that way.     

[Oceaneer99]

Great build, Ray.  It is neat to see how you use patterns and re-apply them at various stages.

I will attempt to make Ray's minesweeper but cannot commit to any project until  my new shop is set up. Maybe late this year, early 207.

How long is your YMS model. I figure 11.33 inches. I am downloading as many photos as possible for future work on your YMS. I have some 1/144 scale sailors that might work with the USS Albatross
