Steve, Do you have a link to the EMT tube/pipe I need for the ball clock?
I see your screenshot in the documents, but I can't find that same listing on Amazon in the US. Can you share a link here? The closest I found is this one: https://www.amazon.com/dp/B0H84914HL/?coliid=I2ASU3G1PL2S17&colid=10KFES8JKEHMD&ref_=list_c_wl_lv_ov_lig_dp_it&th=1 Will this work? Thanks! Steve

That is probably the correct material, but really expensive. The image showing the inside diameter of 1/2" is misleading. 1/2" EMT conduit has a cross sectional area of 1/2" with an ID of 0.622" and an OD of 0.706".
Any hardware store in the US will have it for a lower price. Home Depot has 5' lengths for $4.96 and 10' for $6.58.
