Woodturning - Lathe (Delta 46-460 With Casters) / Old Dog Ramp - Let's Figure This Out

The shop in my southern location is only 75 square feet so I added casters to my Delta 46-460 Wood Lathe so I can take it outside and use it. The problem is I have steps to deal with and the lathe is just too awkward for steps.

Also my dog is getting pretty old so anything I can do to help her out, I will.

So I need to make a ramp. I've never made a ramp and I also want to use materials on hand. That will help de clutter my small space and keep me from going out into the public.
