Re: Ludwig Black Oyster Pearl Downbeat

Rick spotted that I misread the number of zeros on the vertical scale of his graphs. I was using 260,000 as if it were 26,000. Time for new reading glasses methinks. So yes, 1964 +/- 6 months.

Re: Acrophonic? Supralite?

Just for clarification to future readers:

The vertical hole spacing and hole size for the Imperial and Bow Tie lugs is the same. The lugs can be swapped easily as far as I know. I've got two...

Re: 1966 Ludwig Jazz Festival Snare - questions

Examples of pre 1968 scarf joint and wrap interface in the color which can add the most value to a drum if it is original (the Ringo effect). The wrap looks like this because it was put on the...

Re: Acrophonic? Supralite?

Re: Spot welding fissures / cracks in cymbal bell???

I recommend you stay away from ordinary welding and TIG welding, etc. Those cause too much heat and the metal loses temper. The interface between the bronze and the filler material, and where the...

Re: calculate the weight of a cymbal (?)

Thanks for the clarifications. I'm really in the same boat as you with the allometric method because I don't have the original raw data and model fitting.

Here is a plot of the estimated weighs...

Re: calculate the weight of a cymbal (?)

I've started to analyze your weights which you say are from applying a 15.8% per inch increase to get the weight at a different diameter. The first thing I discovered is that 15.8% is not applied...

Re: calculate the weight of a cymbal (?)

I'll have to make a few graphs and show how the predictions vary for the three different models (ratio of areas, percentage increase, allometric). That should shed some light on things. I'll give the...

Re: calculate the weight of a cymbal (?)

There are two methods I use. One is based on the ratio of areas. That models a cymbal as a disk of even thickness throughout. We know that is a simplifying assumption given that cymbals have bells...
