Today I cut the one inch strips into 7mm and 8mm strips and ended up with 70 strips total. I cut a slot in a board to hold the mahogany strips so I could slice them with a razor knife. Then I ran the strips through the table saw to get a nice square edge.

I need to buy some black plastic strips to go between the mahogany. Does anyone know where I can buy some?
Or I may buy a sheet of black plastic and cut it into strips. If I do buy a sheet what is the best way to cut small strips?

Cutting plastic is tough Ed because a power saw actually melts the plastic with it's friction while cutting. Cutting strips as thin as you will need is going to be almost impossible. You may save yourself a lot of money and agrivation by buying the strips already cut. Pete

Ed here is a picture of our familys old Garwood from 1947. My grandfather bought it new in Fall River,Mass. and we owned it well into the sixties when we moved South and Dad sold it. 16 feet long and had 115 HP Gray Marine engine and it would pull three adult skiers at one time at about 35 MPH if I remember right. Sure was fun to ride in. Pete

When i did my Sea Hornet, i used the cover from a black plastic wallet found at Michaels..
http://www.rcgroups.com/forums/attac...mentid=2028368

I had to cut the strips with a hobby knife as that was the only way to cut through it and get a nice clean edge. Even using a knife and steel rule, i wasted about 1/3rd of what i cut as they were not the right size.

Be warned too, sanding it all down is a of a job..

Pete,

Glad you posted the pictures, do you know where the pictures were taken? I was born in Fall River, Mass and lived there until I was 13; then we moved to Calif.

Toesup,

I will check out the craft stores. There is a plastics business close by maybe they can cut some for me.

Can't help with the black plastic... but the trick in finishing is to do the following:

1. cut the strips a little wider than the planks' thickness;
2. When setting them, take extra care to get the plastic strips solidly down on deck, and CA'd to deck and side of planks. May take a bottle of CA accelerator to get the glue to set on open grain wood like mahogany.
3. Then, DON'T sand the strips and planks down, but scrape them instead. Goes faster, and doesn't melt little bits of plastic into the wood. Cabinet scrapers are nice, but I've used (abused?) a plane's blade and razor blades for this task.

Maybe consider black construction paper (small scale) or poster board for the strips...

Thanks Pat,

I forgot I have a cabinet scraper some where in the garage.
Do you think the poster board would work OK? Or if I use plastic and scrape it down flush would it be OK to sand it then?

Hey Ed,
I phoned Dumas the other day and they sell the styrene caulking strips (only white, though) for $1.00 each for 24". I passed as it just seemed too high and figured I could find something cheaper than that. If you have no luck finding black, it's an option.

Poster board: You'll have to experiment and see if you like it... but if you're putting a clearcoat over it (preferably 'glass), no problem with water. Black construction paper is an old trick for the sticks-and-strings crowd.

Scraper: You may find that a scraper is all you need! But yes, sanding planks once the plastic strips are flush will likely be ok. It only takes a few swipes of the paper before you start smelling hot plastic though...

I found something interesting; it's called Purfling and is used in guitar construction; it is .020 wide by.100 high and 34 inches long and is a black fiber material. Here is the web site http://www.grizzly.com/products/sear...spx?q=purfling it also comes in .010 thickness . It sells for .75 each if you order more than 5.

Since the last post I was able to apply a thin coat of epoxy to seal the balsa planking. Then I planked the bottom of the hull with 1/2 inch wide basswood strips, this part will be painted red so no need for mahogany. The bottom of the hull by the bow will be planked with mahogany, because it will show the mahogany below the chine.
