I am new to woodworking- about 7 months now. I have aquired several power tools, including a Delta portable thickness planer. I currently have no way to flatten or edge joint boards. My interests lie in cabinets and furniture making, and I have built some laundry room cabinets, a simple work bench, and a dresser so far. I have realized that I need to produce flatter boards with truer edges for making pannels. My theory is that if I am going to spend money, it is best to buy quality, so I innitially intended to buy a Lie-Nielsen #7 jointer plane. But when I called the company for advise, they recommended starting instead with a low angle Jack plane due to its versatility and multiple blade options. I cannot afford to by both planes right now, and since I am not comfortable with tuning a used or vintage plane, new seems to be the best option.
Is it better to go with the Jack plane to flatten the boards before placing them into the planer, then edge joint the best I can with the Jack plane, or would the #7 plane be sufficient for flattening the boards before placing them into the thickness planer? Lie-Nielsen also makes the bevel up jointer plane, and that is also an option. Thanks for any help you can provide.
