128 Year Old Grandfather Clock Repaired 

Bang a gong!

I'm with you on that

A future video will feature Quantum Lathing.

It may also have to go through something that your not aware of. Agree it shoulda been the same diameter.

P.S. don't worry about the user name my end of the cloth had a little lace.

correct.

Correct.

Correct. And in 1898 came the standardistion conference. BTW, i restored a Löwenherz cutter set recently. Can be seen on my channel.

Thank you, been machinist 35 years. I'm never too old to enjoy learning new things like this. Once you get done learning it is time to move on. Once again thank you.

No problem sir. I take no credit for the info, I had to look it up as I was surprised metric was being used in the 1800s!@@mj_slender6717

I will check it out, thanks.@@mftmachining

Gaday! Today we are repairing a axle on a Cat 883!

He'd still do it on a Sherline lathe too! 😂

Very cool The machining I did when a 100 years ago is amazing The detail the workmanship is just fantastic.

I agree but with the adjustable weight it should be ok.

the new rod may be too thick to flex as designed(?).@@larryfedewa9636

I was looking at that when it is in his thinking that same thought. I really would be interested to know if it did in fact change the pitch enough for just a human ear’s ability to hear the difference. 👍

@@jasonhull5712 the wayt hose spring bells work and with the size block they are mounted to that bell shaped mounting adapter should not make any difference. I assume it mounts on a through hole in a rather thin plate of the clockwork, and that bell shape either distributed load to prevent the plate from bending, or is mostly about how it looks. Turning it down would only be necessary to keep the original look, as someone else stated in a comment. If it was relevant for tuning, the rod length would have been as well and that would then require to absolutely match the start points of the threads anyway, which however in my opinion would be a futile attempt to math the rod length anyways. He measured it just shy of 13.5 cm using a rule, so that measurement might be quite precise, but given the break and as Adam already assumed, possibly some fatigue, i highly doubt you could measure the break exact to a tenth of a milimeter anyways.

it's probably an adjustable mounting leg.. the coils are the gongs that resonate, the block is a dampening weight so that the clock enclosure won't vibrate too badly when the hammers hit the coils...

I sort of inherited my lathe and mill, largely self taught, I have a real issue with my teacher when it goes wrong!

I worked at an airline machining very large workpieces, got a better job offer, then worked at a medical start up company developing and micro machining a tiny catheter type heart surgery device. At first the contrast in the work size was sort of intimidating, but I quickly realized the machining principles were always the same. With the right optical equipment, it wasnt any more difficult. We mounted microscopes on our manual lathes and mills, and made mounts for eye loupes, and magnifiers. Our CNC work was much more challenging however. Even the same ultra close tolerances were required as in the aerospace industry. We also had a very nice optical comparator for our actual inspection, but for prototyping it wasn't very necessary.

I didn't notice any marks on it. The most likely candidates are either to transfer vibration to a diaphragm or horn for amplification, or as a counterweight for resonance.

​@@ItsMrAssholeToYoueven in both those cases, it he should have still sized it to the original as the additional mass will affect the transfer function of both those examples...

@@JaenEngineering Not really. As a transfer bar, the added rigidity would balance-out the extra mass's damping, and the adjustability of all that extra thread (the reason I considered counterweight an option) would allow it to be tuned as needed.
