Wooden block plane sketch

I've been playing with the idea of making a wooden plane for a while and decided to start with a small block plane to replace my vintage Millers Falls No. 57. The alternative would be to buy a Lie-Nielsen #60 1/2 but those little wonders are expensive....

I want it to be a low angle plane but making a wooden plane with a 12º bed is out of question, the body would be too thin to handle the strain, so I decided to take a different approach and instead of making a bevel up plane this will have the blade resting with the bevel down on a 37º bed.

This design should have the same cutting effect of the #60 1/2 since the angle of attack of a bevel up plane is the sum of the bed angle and the angle of the bevel of the blade (usually 12º + 25º respectively).

Pictured above is a sketch I made using SketchUp to have an idea of the dimensions. I guess it will work out fine!

The SketchUp model isn't perfect but will give you an idea of all the parts and dimensions.

Traditional crib - design stage

In the last few days I've been busy designing a traditional crib for my baby daughter and thought it would be a nice feature project for the blog. You can download the 3D SketchUp model for free and check all the measurements and joinery details for yourself.

This project will be my first furniture piece and I feel nervous just to think about it. For one I have never build anything of this size and I want to try a few new things both in terms of construction and finishing.

The frame will have to be a knockdown design so it will be easy to get it out of the shop and into the bedroom. Instead of using standard hardware for this purpose I decided to join the side rails to the posts with a wedged mortise and tenon with a loose wedge made of ebony. This will be one of the design features of the piece influenced by the arts and crafts style.

Another design feature will be a drop side rail for which there are no details in the drawing yet. I have a few ideas in my head at the moment and will post an update in the future.

The crib will be built with solid cherry and will have a shellac and wax finish which are both non-toxic finishes, something to pay attention when making furniture for babies. Both shellac and beeswax are approved by the FDA and are widely used in the food and drug industry.

I also tried to follow all the guidelines regarding crib design. The distance between the slats in the rails is 60mm, the rails are approximately 600mm high and the posts don't protrude above the top headboard.

The images on the left show some of the joinery details.

The first image is a simple mortise and tenon used to attach the top headboard to the posts, nothing fancy here.

The second image shows something I'll be very proud of if it works out well.

The bottom footboard will attach to the post with a mortise and tenon which will have to make enough room for the through tenon in the side rail which in turn will be wedged to lock thinks in place.

I guess that if this isn't sturdy enough I'll add some screws to the joint and cover these with some ebony pegs. What do you think?
