I'm curious about my mill tram

Here's one of the vise stops I mentioned. It's beat up, but it's quick & easy to make. This one is made from a 3/8" x 7/8" cold rolled bar and it has two 8-32 Allen cap screws to hold it in place on the back jaw. I prefer to make these out of mild steel so if an end mill should contact it, the end mill isn't damaged. 20211018_164724 4x6.jpg

One of the dial indicators on the Edge Pro Tram is broken, I've used it only a couple of times. The bezel separated from the face, and won't 0. My Noga spindle mount has a kinda short sweep, but I'll see what I come up with. Thank you for the replies.
Over my time in machine shop, I bought all kinds of indicator holders and spent lots of money in the process. The way many of us trammed in Bridgeport heads was using a soft steel rod 6 to 8 inches long. On one end, make a 90 bend so you have about an inch and a half to hold it with a collet or a drill chuck. Then use an indicator clamp that fits the rod and holds the indicator. Then sweep the table until the heads trammed. https://www.ebay.com/itm/303018822331?hash=item468d544abb:g:o-YAAOSw11BcL336

It's almost 21 years since I worked as a machinist. So many of my tools were sold because I thought I'd never use them again, and now I have a Bridgeport and need the tools I once had.
