Thank you for the suggestion Bruce, that is what I did.

I also posted some PDF files there about what I have learned about the core-box plane. You may find them interesting.

@patternguy I hear about jointers that can add draft to a pattern what does that mean?
Ive never understood what that does.It must be very important since a Oliver pattern makers jointer is awesome machine.

Draft is the taper that lets your casting sand core slide out of the pattern instead of getting stuck between parallel walls.

OSB is right about “why” draft is on a pattern or corebox. The question is, “How do you add, or subtract, draft to a pattern?”.

One way is to plane a board to thickness, then set the joiner fence at the correct angle and accurately joining the edges, one edge ” angled in”, and the other edge angled “out”. If you stand the wood on edge, what you have is a parallelogram.

Parallelograms are good shapes for constructing pattern equipment. If you have 4 parallelograms of any given length and arrange them to form a box, the inside walls of the box will automatically have draft, and the top surface of the box is flat “plane” that you can control the height of.

A sturdy joiner with flat, true tables, and a large, accurate and true fence is vital to maintaining accuracy and precision.

Oliver woodworking equipment was well engineered and manufactured machinery that made a name for itself supplying quality equipment to a well respected, skilled trade.

Interesting plane. I’ve made pattrns for lots of sailboat parts that I couldn’t buy but core boxes that I could climb into were beyond my scope. I have great respect for “real” pattern makers.
If you are interested, my stuff looked like this.

I cant help you with the plane, but I do remember when I was an apprentice seeing pictures of toolmakers wearing suits while working in the tool room.
