Boat Building Questions
Getting materials together for a boat now... and have a few questions.
1. It shows to cut the oak stem like a triangle... 3-3/4" on the back side and then 45-degree each of the other two sides. That leaves a sharp point on the end, is this the best way to build a stem?
2. What size/length silicon bronze screws are needed to build the boat?
3. The plans show a 3/4" plywood transom, but my plywood will be 1/4" Meranti on the sides and probably the transom to have the same plywood all around the boat... any ideas?
Thanks for your help...

You can dado out the sides of the triangle to make the plywood flush. There is also the option of planing down the point so it's about 1 inch wide and flat. It could also be ripped down on a table saw. Run the plywood sides up to the flat edge then cut a cap to cover the stem and the end grain of the plywood.
You might need an assortment of screws, sizes and lengths. I don't use any screws so I don't have a good idea of the sizes which would be useful.
I just put a transom together a few weeks ago. I had 3/8 so I just laminated 2 layers with epoxy to get 3/4.

My transom was 3/4".
I think 1/4" would flex too much and you'd run the risk of loosing your hull shape.
An eyebolt would pull right through the 1/4" if loaded.

I did not mean to use 1/4" only on the transom... just wondered how to glue it to a 3/4 plywood backing.

1. the older boat plans have a point on the stem. Once the sides are attached you can plane the sides and the point down to a reasonable width and then add a false stem or stem batten to cover the plywood edge grain. It is best to have the finished width be at least 1 inch so you can attach rings or eyebolts.
2. If you don't want to get too crazy with different screw sizes you can standardize on 1" #8. If you need to reach into the wood to get a good grip just counter sink a little deeper and then plug. If you want to not have plugs then you will need a number of different screws from 1" to 1 1/2 inch.
3. You can glue up a transom with epoxy or you can purchase 3/4 in Meranti. It's ok to go to 1" on the transom. Larger will cause some weight problems. Smaller than 3/4 will not support anchors etc.
It looks like you might have a fir transom. You can laminate the 1/4 in Meranti to the 3/4 transom with any good laminating epoxy. I use System Three Silver Tip for all my laminating.
