Build Log
Dumas 110 ft. Sub Chaser

After building Dumas' PT 212, I decided that I wanted to try a plank on frame kit. I have one of the old, all wood Seguin Tug kits in the box on the shelf. I thought this kit would be good practice for the complicated hull of the tug. Besides that, I really like the smaller patrol/escort boats.

The boat is a stand off scale 1/35. Dumas gives the reason that they choose this scale was due to the many figures in 1/35 that are out there for manning the boat. Still, it will make a decent size model at 37 1/2 in. length X 4 3/4 beam.

This is to be my first all wood kit. I opened the box and my wife said, "Where's the boat?' I told her she was looking at it! It seems quite daunting! The first to do was to check that all the wood, metal, plastic and fitting were in the box. So, everything was laid out and separated and numbered/marked lightly with pencil. Everything was there except for the 1/16 brass tube for the boat davits. Not a problem, I'll pick that up the next trip to the hobby shop. Included is a full size drawing of the boat, a booklet of drawings that works hand-in-hand with the detailed instruction manual.

Next step will be to start gluing some wood together!

The full size boat had 3 screws. Are you going to change the drive train?

Looking forward to watching this build. The SC is a nice subject. Years ago a guy in our club had a 1/2" scale SC. I managed to catch a photo of it with my Dumas Crockett. In half inch it's a big boat. 1/35 sounds like a good size and it will look at home with all the Lindy PTs about.

The hull on the Crockett was a nightmare to plank as the strips needed to be spliced to get sufficient length. The flair in the bow played hell with the splices. It will be interesting hearing your impressions of how well this kit builds as a novice plank hull builder. We do allot of events and we are always looking for good kits to recommend. I'd never recommend the Crockett to anybody less than an intermediate skill builder. I wasn't when I built mine.

If that hull becomes a pain, Kap'n Karl offers one in 1:32 scale.

Thanks for the plug, Chuck. Actually, this boat should not present much of a problem for plank-on-frame, as there are no tricky compound curves to struggle with.

Still can't understand why Doofus went with that orphan scale though---.

Thanks for the interest. I'm planning on using the kit's recommendations for the motor/prop combination. I'll be using the recommended Dumas 6 volt motor (as I have one of these in my parts drawer) and the single shaft and prop ( more parts in the drawer I found after rummaging around, the parts kit Dumas has for the boat is $45.00...a little much ). The top speed for this boat was 18 knots, so this Dumas 550 single should be ok. I am a little concerned with the narrow hull and high profile of the boat. Looks like it may be one to roll excessively.

Starting to put the keel together (after building the included stand). The stand like the one for the PT 212 is pretty useless for anything except for display at home. Will need to make something a little more substantial.

The SC has very little superstructure. If you look at the 1/2" scale SC next to my Crockett they are close in dimensions. IIRC the SC was MUCH more stable than my PG 88. Both would list in a turn but the SC was more nimble and would snap back on keel faster with less oscillation.

I'm glad to hear that! I have heard that if you put the ballast in the very bottom, center of the boat it opens it up to a pendulum effect. Any suggestions on placing ballast. Instructions say I may need to add as much as 2 lbs.

I think 1/35 scale is pretty reasonable, given the large number of military models and accessories available in that scale. There's also the big Italeri PT-596 in plastic, and a dedicated set of WW2 crewmen, too.

1/35 is actually a great scale for military. My Crockett had a 1/35 Italeri Seal Team on the stern awaiting deployment. At one time I had a dock for it with all kinds of 1/35 stuff, a deuce & a half, jeep, ambulance, M 60 tank, a workshop, and lots of people. Still have most of the stuff in a box someplace. I even had a Huey with the main rotor powered but didn't have room for it.

Ballasting is always tricky. Every model is so different. I try to allow access so I can add ballast as necessary till it's right. Learned that lesson with the Billings Calypso.

I agree with Karl.

Though I understand that 1/35 scale is the defacto standard for military modeling, they should have made it in 1/32 simply because there's a fiberglass hull and both companies would benefit!

I certainly would have bought the kit and the Microglass' hull because then it would be a "complete" kit. I've done the same with Microglass' lobster boat because it fits perfectly with my vintage Midwest Shrimp Dragger.

Rarely, do I build from a hull. I'm old school. I'm biased toward kits with fiberglass hulls.

In any case, happy to see this kit appear. In a world of RTR's this is greatly appreciated.

Happy building!
Oliver

OK, the keel is finished. Several pieces for the bow and the one for the stern were laser cut. This made it pretty simple to cut them out and lightly sand the edges, just enough to sand the dark brown from the laser cutting. Each piece was doubled, except the long portion of stock 1/4 X 1/2 basswood Dumas recommends using epoxy for the glue up of the keel but I used CA. It works just as good on wood as epoxy, you'll destroy the wood before you break the seam.

A full size plan for the keel was provided for assembly. Put down wax paper and glued the parts together, allow to set overnight. Very basic.

Building the frames was just as easy. They were cut out of their carrier boards, edges sanded inside and out. A right and left were glued and a length across the top (deck level) added. Each one was dry fitted to the keel to make sure it would fit and sanded accordingly. Most had to be sanded so the would fit on the keel properly. Frame ten is not glued together, it is glued to either side of the frame later.

Two jigs are supplied, these are used to align the keel to keep it straight. A line is drawn down the center of the building board, and a vertical line down the corner of each jig. The jigs are glue to the building board to line up with the center line drawn. The frames are then put in place and aligned with marks that were place on the keel during construction from the plans. A jig is provided to use with frames to get to the proper angle on the keel. They will tilt a little toward the stern. I'm not really sure why, but I'm following the instructions. When each frames is in place, it is glued to the keel and to the building board. When all the frames were glued, I glued a stringer down each side, be sure to dry fit the stringer in it's slot before glueing to the keel, it'll be very hard to sand it after it's in place. I will use a small wood chisel to knock it loose. Should work great. You can't hurt the frames as the have small "feet" on the for this purpose.

Next, I'll start planking the hull......
