Hey guys I need your help. My principle came to me today and asked if I would like a stipend assignment. She handed me a picture of what I have posted below. It’s a ramp that children with week upper body strength use to pull themselves up while on a “scooter board’. The ramp is easy, sheet of plywood with poplar runners, use a dado for the joinery. The box is also fairly easy. plywood with some bracing on the inside, rabbits then glue and screw at the edges.

My issue is the transition from the ramp to the box. How do I get this flush? What do use for joinery, or do i make it modular? Let me know what you guys think?

I have built quite a few ramps for wheelchair access, and usually when attaching the ramp to the landing or “box” as you have here, the best is to biscuit (or tongue and groove) a hardwood strip into the section meeting the box.

You then fasten it to the box (screws or maybe hinge) and plane or sand the hardwood piece to fit the slope of the ramp and box.

I can see it in my head as I write this, but am not sure it is clear now that I read it.
If you like I could sketch it out, but I hope you get the drift…

I guess the simplest way to say it is you could attach it, and plane the plywood to fit, but plywood doesn’t look the best when planed, that is the reason for the hardwood.

The more I look at what I wrote, the less I think it will be understood.

I’m going back to the shop.

I’d do a French cleat style attachment. Rip a strip with an angled cut. Firmly attach one of those pieces to the ramp, the other to the face of the platform. Use a bail latch on either side to keep the ramp firmly pulled down into the cleat.

The one thing that doesn’t do is provide a lot of kick-out stability if the platform rolls towards the ramp, but that may not be necessary.
