Here I am reading about the chalkboard on the "step by steps" and a customer walks in wanting a chalkboard - go figure. Not being familiar with the stuff (that's why I'm reading) I'm considering building my own A-frame.
Will poster paint make the wood writeable like a chalkboard (and erasable)? Does anyone know of a source for chalkboard?

Chalkboard paint (not poster paint) is available in green, black and grey at your favorite sign supply store!
Two coats on hardboard...and you have a chalkboard!

These are some T-boards I did last week for a new butcher's shop in a supermarket. They're coated with an oilbased blackboard paint. You can also do them as A-frames.
The butcher was done with basecoat auto paints & clear coated with a good waterbased flat clear. Lettering was enamel, brushed. No vinyl used, just a bit of app tape as a mask where needed.
(& John's right, don't put a turpsy roller in the fridge or freezer!)

thanks guys. I knew I'd get the right answer here (and a chuckle too!!!). Once painted can these boards be written on with chalk?
Nice work Ian. That's exactly what I'm looking to do. From the back it looks like the chalkboard is inset into a frame?

No Denis,
the material is what we call 'Weathertex'. It's a masonite/hardboard which is tempered a bit for weather resistance. It's 3/8" thick, (9-10mm) & has a preprimed top surface.
I just used the jigsaw (scrollsaw) to cut the top silhouette, then routed a slight chamfer on the raw edges & all round, primed that, scuffed the lot & put a coat of white enamel on it , then did the airbrushing, then brushed the blackboard paint on top on the front. Boforehand, I'd rolled the terracotta colour on the back (left over from a job last week), and at the last minute I thought it would help impress the customer to have two useable surfaces, so I brushed the black on the back too.
I welded up the Tee legs from galv, square inch steel (gal RHS we call it here) & welded the ends tapershut & bolted them on with three 1/4" or 6mm bolts each.
