It’s Mike, here again, continuing with my free plans to help you build amazing DIY cabinets. Today I have written a plan on how to build 21″ wall kitchen cabinets.
Let’s get down to the list of things you need to have before starting the job.
- Plywood Boards for face frames |1X2S | Measurement: 8 feet
- ¾” Plywood Boards neatly ripped into the strips with the following measurements | 10 ¼” Wide
- Plywood Boards for Back | ¼” Thickness
- You can use plywood scraps for back support
- Plywood board for the back | ¼”
- Pocket Hole Screws | 1 ¼”
- Finish nails | ¾”
- Couple of Edge Bands | for shelf fronts
- Shelf Pins
- Concealed hinges | 1 ¼”
The list of tools that are required to get the job completed:
- Tape Measure
- Table Saw
- Speed Square
- Safety Glasses
- Kreg Jig
- Hearing Protection
- Brad Nailer
- Miter Saw
To make the most out of these plans, it is always advisable to go through all of the material more than once. If required, you can try reading it a couple of times before putting the plan into action.
Helpful precautionary checklist
- Ensure you work on a clean surface
- Always ensure the boards are neat and straight
- Do not allow debris in your work surroundings
- Practice pre-drilling holes wherever necessary
- Use finish nails-glue combinations to ensure firm hold
- Work smart, be safe
Cut List | Dimensions
- ¾” Plywood boards for sides | 10 ¼”X30″ | 2 No’s
- ¾” Plywood boards for top/bottom | 10 ¼”X19″ | 2 No’s
- ¾” Plywood boards for back top support | 1 No
- ¼” Plywood board for back | 30″X20 ½”
- 1X2 boards for face frames| 30″ | 2 No’s
- 1X2 boards for face frames | 18″ | 2 No’s
- Door Size | 20 ½”X29″
Note that shelves should be precisely cut to accurately fit if you consider using edge banding.
Step-by-step guide to building 21″ Wall Kitchen Cabinets
01. Start with making up the side boards by neatly drilling pin holes on the inside portion of the adjustable shelves. If you would like to complete this stage, you can do so. However, it is much easier to complete this step as an initial step rather than having to do it after the assembly stage.
- For deeper shelves | Adjust the rip width
- For taller shelves | Cut the sides taller
Drill a ¾” measurement Pocket Hole facing the front portion which will be used to attach the face frames down the line.
02. Continue with attaching the sides to the top and bottom panel. Drill a pocket hole of ¾” to attach the face frames on the top and the bottom portion of the cabinet.
03. The back support step is an important highlight since you need it to hang the wall cabinet on the wall. It is preferable to use prefinished plywood for this step and reuse the leftover scrap for supporting the back portion of the cabinet.
04. You can use ¾” finish nails with glue to have the fixed shelves attached with a firm grip. Attach the top, side, bottom, and back similarly with finish nails and glue.
05. Consider building the face frames separately with ¾” pocket holes and have Pocket Hole screws measuring 1 ¼” through them. Attach the predrilled holes on the external side of the cabinet.
06. Ensure you have the shelves cut measuring ¼” lesser in depth and width at the top and the bottom portion to allow the shelf pin and to add edge bands with ease.
07. Use a full overlay with concealed face frame hinges to complete the doors. Ensure you give a ½” gap to the bottom while maintaining a gap of ¼” at the sides.
After finishing the project, you might find some gaping holes in the finished work. You can consider filling these neatly with wood fillers. After filling the gaps, allow ample time to let these dry.
If you find it necessary, you can also consider applying additional coats of wood fillers if required. Use sandpaper to completely sand out the wood grains and to remove any remaining residues.
Wipe the project clean with a damp cloth. Use a wood conditioner or a primer if needed.
