This great little sit-on children’s digger is such a cool addition to our backyard. Simple to use with only two levers and a rotating seat, our niece and nephew can dig away in the sand box. A few cute additions such as some caution tape and it looks like the real deal!

Caution Grip Tape (for the finish)

Steps
Step 1
Start by cutting each of your components using your selected timber. You will need to draw and cut:
- 2x levers
- 2x short arms
- 2x long arms
- Pieces for the bucket
- Seat
- Main arm
- Chocks to lift the seat
Step 2
Cut two “tyres” using the 35x70mm treated pine. Then cut your base using the 9mm MDF. Frame this using the extra 35x70mm timber turned on its size to loose the height. Screw these components together using the 10G 30mm screws.
Attach the seat to the chocks and then secure this to one side of your lazy Susan bearing plate. Then screw the other side of the plate to the base.
Step 3
Sand all of the components thoroughly (rounding the edges) and then begin drilling a hole in the joints. Use the bolts to attach the arms and levers.
Cut the aluminium to size, sand the edges smooth and drill the same sized hole in each end. Attach to the levers and then to one short arm and one long arm to allow the arm to move freely.
Step 4
Pull apart all components and paint/varnish.
Step 5
Add rubber to wheels and caution tape to feet area to complete the look. Add some self adhesive foam to the seat for comfort. I used black electrical tape to cover the handles but you could also paint or use the self-adhesive rubber.
Step 6
Assemble all the parts and enjoy!
Optional: I added some rubber door stoppers to stop the digger from rotating beyond 90 degrees. This assists in ensuring the sand stays in the sand box!
What a sensational project @Alicia_Woodwork! It turned out amazingly well, and I have to say, it’s really inspiring. You've even got me considering building one for my son—he would absolutely love this! I think this might just be my next weekend project.
Thank you so much for contributing such a detailed guide for our members to follow. It's really helpful and will definitely make the process easier for others looking to take on something similar. Well done!

Afternoon @Alicia_Woodwork
I caught the thumbnail in the coner of my eye and went "No way"! 
These diggers turned up made out of metal when I was a teenager and the regret that they hadnt turned up when i was younger was high! Love the design and how you have put it together
Really nice work!

how do we source the bucket for the sit on child’s digger?
