I have a piece of 3/4" rod that is machined down the the metric bolt size of 18 mm. And I have a piece of 1.5" round stock with a 3/4" hole bored in it that holds the outer bushing sleeve. Basically the same as yours, but I use a steel bushing instead of the poly one so that I can weld it solid on the jig without melting the bushing or having to pull it out after tacking it and hoping it stays straight. Which it won't.
