what i did was cut a broom stick into a 4 inch peice then cut it in half, so i had two, inch peices of broom handle, then i filed down half of the 2 inch peices so the first half was normal broomstick size, then the other half was filed down to fit inside the t bar, then i did that to both if the two inch peices, then i stuck it into the end of my bars and hammered them into the bars, when it hit the small lip where i had begun to file down, it stopped, so now a half inch is in my bars and a half inch sticks out, so make sure that the wouldnt fall out i put a peice of ducktape around the bar and wood, i dont think it will fall out though its really snug, so thats my way
