Welcome to the Bunnings Workshop community @Tiff. We're so pleased to have you join us. Our clever and creative members are sharing helpful advice and inspiring projects on the site every day, so we're confident you will get plenty of helpful information, advice and inspiration for this project and many others to come in the future.
Is this wooden lectern on instructables site similar to what you had in mind? If so, have a good look at the plans and let us know if you have any specific questions about replicating it. We'd be happy to help. I believe the only lectern that has been previously shared on Bunnings Workshop is this one from experienced woodworker @Yorky88.
We're looking forward to seeing what you can create.
Please don't hesitate to post anytime you have something to share with the community or need a hand with a project around the house and garden.
