I use a piece of pvc pipe with to instal the race. the pipe alone will work fine for 1" but I had to make a little wooden "donut" of sorts to use with the pvc pipe for it to work for 1.125". and maybe a bigger piece of pvc pipe, I'm not sure. and a vice that was very carefully set with the jaws just the right width apart to remove. you could put some tape on the jaws to add a little protection.
