Hi Everyone, I've got a shade structure made with 1 3/8" top rail. I want to use the structure to anchor shelving and other maker pipe builds that are made with 3/4" EMT.

I already have the shade structure so can't change the 1 3/8". I have a couple of the 1 3/8" maker pipe Top Rail T connectors. But I struggle to figure out how to shim them down to connect to 3/4" which then opens up using all of the awesome 3/4" connectors.

I've attached pics of the structure. I'd like to build shelves with 3/4" and anchor them to the shade structure. I'd also like to build a clothes hanging rod out of 3/4" EMT and use the Top Rail T connectors to connect directly to the structure. Stuff like that.
