Email from Karen Salaz, 19th Judicial District
This is amazing news. I can’t believe you were so successful and so quickly. I also loved the article about you and your father in the paper. I’ve not yet been able to get to the photos but am looking forward to seeing them when I get to a computer or decent phone signal.
Everything you have described below sounds perfect. Do you happen to know if the county will be making any time adjustments if need be and winding it or if that is up to me? I would love for you to do the polishing of the pendulum when you come by. I will bring in some paste wax and ammonia for the glass and wood. If you feel there are better products to use please let me know.
I am so disappointed I was not there to see all this and was selfishly convinced it would take a good three days to do the work. In the end it is all good. Getting the clock running has been on my bucket list for the 10 years I’ve been in my position and I am retiring on June 30. You truly have made a dream come true for me. Thank You and surprised the heck out of everyone who told me it could not be done so should just give up.
I still can’t believe this is happening. Thank You so very much.
Warm Regards. Karen

April 21, 2017 – Update from Tim Orr
Thanks to Randy Schneider (and his wife, Robin) and Chuck Daldry for their work in getting the Hahl master clock in Greeley cleaned, lubed and running! The below is just in from Jennifer Finch, who was there shooting photos and video yesterday.
As you can see, Weld County plans to invite us to attend their celebration of the courthouse’s centenary on June 30.
When we left it, the clock was running well. Over the next few weeks, we’ll help the court people get it regulated and see what we can do with respect to the remaining slave clocks in the building.

I will be making a trip to Greeley next week on Tuesday morning (April 11) to discuss the scope of work with the building and grounds people and with Karen Salaz. I’ll also get to see where they are providing us with a work area, etc.
We have tentatively scheduled actual work to be done on Thursday and Friday, April 20 and 21. Whether or not we can complete the work in those two days is a bit of an unknown, but we can certainly get quite a bit done. Again, I am leaving the management of that part of the project up to Chuck Daldry. I should think Chuck would welcome a couple of people, at least, to assist him.

Here are the responses I received from Karen Salaz regarding work on the Hahl master clock in Greeley:
- Where is the work area? Fourth Floor, Division 10 judge’s chambers
- Near to master clock? On same floor? Two floors up [Note: There is an elevator.]
- Is there a sturdy, 4-wheel cart we could use to move things to and from the work area? Yes, we have a platform dolly we can use.
- Does the work area have a sink and running water for cleaning parts, etc.? There is one directly across the hall about 10 feet away. We can live without it, but it would be nice to have access to such.
- Presumably, it’s well-lit and has electricity for any power tools we might need to use. The room has windows and lights and electrical outlets
- Can we get tool kits cleared by security? Even if they contain sharp, pointed tools, like knives and awls? I had a tiny pocket knife with me last time, and could not bring it in. If I accompany you we can get anything through.
- Can we get special parking or parking permits, so we can park for more than 2 hours? Yes, I can provide those for the parking lot southeast of the courthouse across the street.
- Could we arrange a ladder to inspect the clocks mounted high above the floor with an eye to converting those to quartz? I can do that with a date and time the B&G guys will help us.
- What days of week/hours of day would be best for us to work on the master clock? Honestly, since you will be in Division 10 any day will work and you can leave things locked in there as long as you would like. If we could avoid weekends that would be appreciated as we also own a ranch so weekends are pretty full unless it is raining or snowing. My normal workday is 6:30 a.m.-5:00 p.m., however I am more than happy to stay as late as you would like or come in earlier if that helps. If I am not here I will make arrangements for someone else to get whatever you need.

Just to let you know that we are waiting for next steps to take place. The Weld County officials are to prepare and send to me a contract detailing what we will be allowed to do (and NOT do, I suppose). John Bartos and I had a talk with Tom Erb of Electric Time, who says he will send me information on some quartz movements that could be made to drive the remaining Hahl clocks in the walls.
If I have not made you all fully aware, the situation is that we are now told that there are probably – at most – only three remaining Hahl dials in the building. Three were removed and replaced by “Wal-Mart” clocks. The remains of these, alas, have not been found, and no one seems to know where to look. Another of the Hahl clocks, the marble-dialed one in the courtroom adjacent to the master, was converted to quartz some time ago, so that slave movement is missing too. Building authorities insist that the clock on the top front of the building, while it once may have been a Hahl, was converted to electricity some time ago, and they are trying to get it running again.
In addition, building maintenance says they remember an incident in which some workers cut through the pneumatic lines during construction.
They do want to get the master working again, and are open to discussion about how we might get such slave dials as remain to at least display correct time.
Our analysis suggests we ought to work on getting made a better winding crank for the master, something with more mechanical advantage and less likely to damage the movement. We’ll probably need another visit in order to determine the dimensions we can work with.
We also should consider doing as best we can to clean that master movement in place.
Nothing at all can be done until we hear from the county’s lawyers, however.
My thanks to everyone for participating, sharing photos and especially to Solly for his research on historical documentation. I will let you know what I hear as soon as I hear it.

The Scientific American of October 5, 1878 had something on Victor Popp’s pneumatic master clock driving slave clocks all over Vienna. He used air because “Electric clocks are among the most unreliable of chronometers, electricity by its very nature being the most capricious of physical agents, etc, etc”
There is a Hahl clock working on

You can see it in action on www.youtube.com/watch?v=VF5DMLo6Rr8 I’m not sure why there is also a mercury section.
