Dumas 19' Racing Runabout **Bash Job**

OK pics start here at FIG. 8 dont ask.

First problem was I could not get the chine to stick to frame 1. I let it cure an inordinate amount of time but the epoxy just would not set -maybe I mixed it wrong or it was too cool- but it would always pop out so I CA'd it in place.

Also I somehow missed step 1 & put the frame together without the steering column support but I later managed to place it ok. I think.

Actually started it 7 months ago with a pause that's why I dont have earlier pics lost the file somewhere.

Here with the bottom planks put on... I must not have sanded the front keel area enough because there is a gap in the middle hope it does not affect anything later.

I shaved the edges of the planks with an exacto as closely as I could to save sanding time with that step.

Third pic is the aforementioned steering support column I almost forgot.

Man I guess my first Midwest build spoiled me but I am having a really hard time following these diagrams- takes a long time for me to figure out what part of the boat I am looking at/from what angle.

Rear side planks installed. Once again I have gaps between the plastic sheets- they were too stiff to fold around the bottom edge. I guess I will have to mix up some microbaloons and fill the gaps.

Looking really good so far, my runabout is up to the stage of staining and glassing, you have a great part coming up, the mahogany planking, i really enjopyed the deck planking with the white styrene strips, look wonderful when it's done.

I too had a fair few gaps in the styrene subplanking, after filling it with auto bondo it looked just fine.

Keep up the good work

Ah yes I forgot it will be glassed down there so epoxy would just be messy and more than necessary OK bondo it is- recommend any specific type/ brand?

I think the instructions state not to glass the bottom, but many people have... As far as bondo goes i have just used "Evercoat Rage" in the past, only because i had some on the shelf, they also have lightweight bondo but have never used it.

Front side planks put on. Instructions say the gaps in the side wont matter since they will be planked over. The overlap was so severe I took my dremel out for the first time and -wow did it save me time- I was estatic until whoops gotta go back and repair THAT now.

I have seen someone use bondo to shape the bow instead of balsa blocks having never worked with bondo Im leaning towards following the instructions.

Maybe with bondo you get more chances to get it right

stick with the balsa blocks per the instruction... it would take a ton of bondo (which will crack) to make that bow piece.

I've been using Evercoat Polyester Glazing Putty on a styrene build and couldn't be happier.
