Mez H1/B2 in the UK

[Eclipse DDS]

'Allo 'allo,

Recently I have purchased a Mez H1/B2 that was imported from Czechia to the UK, and I'm going to try and get it up and running properly!

So... there was a bit of an accident that happened yesterday when we were poking around the Mez...

Here is the video covering the topic: https://youtu.be/A8DyS0l40OU

Also attached are a couple higher-quality photos of the damage caused.

Nothing that a bit of welding can't fix

Just thought I'd throw in a higher-quality image of the wire terminals too, if anyone could give any guidance regarding whether they're correct that would be very much appreciated!

Amazing! I wouldn't worry about that crack as long as it doesn't affect the function of the siren, it's fine. i'd recommend either removing the stator or rotor (depending on which one comes off first), and trying to wiggle the shaft of the motor left and right gradually until it becomes loose. Be careful not to damage any of the components. Getting that rust off of the stator and rotor is a pretty big factor for when it comes to running, so it doesn't scrape the stator. Remember to check and oil the bearings. If it's a brushed motor, I recommend checking the brushes. Other than that, good job! Looking forward to seeing how this turns out.

EDIT: Didn't see the welding part. It is CRUCIAL to remove the stator* during that so you don't accidentally weld the rotor and the stator together.

Ah, I see, thanks for the information! An interesting thing about this siren that I keep forgetting to mention is that the stator and motor surround is all a single-cast part, so to be able to get at the motor we'd have to remove the rotor anyway, which is the next thing we'll be doing. Repairing or replacing the bearings is going to be the next step, as that is what is causing the siren to have a rumbling sound as the rotor spins. I'll post again once we get that rotor off and see the motor itself

Woops! Made a mistake I meant to say remove the rotor while welding. Looking forward to it! Hope all goes well!

Greetings!

Apologies for the wait, I've been procrastinating on making this video for a while. We replaced the bearings, and now it runs as smooth as butter!
Also yes, Carl did accidentally smash in the bottommost bearing cover... we'll see what we can do about that later, heh.

Anyway, I can't figure out exactly how to embed a video on here, so here's the link for now:

Here's a quick update on the Mez siren.

Hopefully we'll be hearing it soon

Woah! Great job on the restoration so far! Nice to see it freely spin. In that case, this sucker will be running in no time! (Well, if the motor works. )

We couldn't have picked a better location to test it, the echo was INCREDIBLE!

Almost all reactions from local residents were positive, which was quite shocking.

Unfortunately, we could not do a full 30 seconds of the Attack signal because we kept triggering the overload protection in the switch that we wired the siren to. We will give the siren a try another time once we have found a way to correct this issue. If anyone has any suggestions on how to fix this, they would be highly appreciated.

Anyway, here's the video!

I made a video about the test for the company's YouTube channel, feel free to give it a watch! I tried to go for a more professional and informative video format than I usually do, I hope you enjoy!
