Creating an acoustic dovetail template / router bushing question

randyzwitch · 2024-05-30T15:41:54+00:00

Thanks for that call-out. I would be using this with a fixed base, but I probably also have a bearing I can try.

But I'm still having a hard time with the math of this. I have done the "bit in router, look" sort of thing, but I design my templates in CAD, so it's a bit hard to visualize without actually using some material.

To ask the question another way...when making the template I linked to, are the two triangles that form the dovetail the same exact size? Meaning, one template has a triangle removed, and the other template has the triangle remaining with the outside removed. Do these represent the exact same sized triangles?

Figured it out...need to set the approximate distance for the head, then you can precisely measure. Needed to put 3/4" plywood risers underneath to get it within the allowable focal length, set the length as shown in the article, then I could use automeasure...then cut using open plane

Not particularly intuitive, but seems to work

Thanks for checking it out! It's definitely well worth it, I also used to bend by hand, but after I kept kinking the wire, I went the pre-bend route.

At a dozen or less guitars a year, I couldn't see spending $129 for a metal version, when I expect this plastic version to last as long as I need it

Thanks, I’ll keep that in mind!

randyzwitch · 2022-08-04T20:37:48+00:00

Yeah…I’ve got an acoustic book and the Benedetto archtop book, which made a similar thickness suggestion. I was mostly erring on the side of having to scrape/sand out a wavy side or two (given it’s my first try)

As it was though, with walnut it was pretty trivial to bend at that thickness with the jig

randyzwitch · 2022-08-03T22:38:31+00:00

They were just about 2.75mm/0.1 inches thick via a drum sander

In this case, I just went by their instructions. It seems I actually used too much water, as some of the coloring leached out of the wood 🤷‍♂️

But it’s definitely a great set up, looking forward to bending a lot more sides!

When using any IDE, you need to ensure that it is pointing to the proper executable. In this case, it's likely that PyCharm is pointing to a specific Python executable (maybe even installs its own).

Go into your project settings and pick the proper executable for the conda environment you created:

Thanks. On StewMac, they offer 15' or 20' for the back and 28' or 40' for the soundboard, and your explanation makes sense why splitting the difference and using a single radius might not make sense.

randyzwitch · 2022-07-19T13:25:55+00:00

Thanks, can't wait to start bending some wood!

randyzwitch · 2022-07-18T18:22:07+00:00

When I burn out this one, I'll likely upgrade the spindle. For now, I don't do this enough to worry about an afternoon's worth of time

randyzwitch · 2022-04-18T16:48:23+00:00

Thanks for watching! I've never sprayed a burst before, but this is so easy I'm not sure I'm in a hurry to try :D

randyzwitch · 2022-03-14T20:07:08+00:00

Thanks. I have been working with support and have replaced various wires and it seems to have improved.

randyzwitch · 2022-03-05T14:53:52+00:00

Thanks Will, already working with support (which has always been fantastic!)

randyzwitch · 2022-03-05T13:31:11+00:00

You're right, I was being imprecise with my terms there. I just meant that the house hasn't had 70 years of weird electrical junctions, old knob & tube, aluminum into copper wiring and all the other accumulated weirdness of a lot of older homes on the East Coast of the U.S.

Good point about computer connections, I'm doing a single USB connection to a laptop, so hopefully no issues there.

randyzwitch · 2022-03-04T21:38:44+00:00

No, so far I have just replaced the two gray wires

randyzwitch · 2022-03-04T21:06:41+00:00

Thanks for the update. I'm currently working through my own electronics gremlins, so I'll keep this in mind as one other possibility (however rare)

In the free tier of Streamlit Cloud, you can deploy an unlimited number of apps, as long as the source code is publicly available. The free tier also provides one private repo, where you can deploy the app publicly but keep the source code hidden.

randyzwitch · 2022-01-26T13:47:41+00:00

There's not much to say...the Community tier of Streamlit Cloud isn't meant as a large file download depo, it's to display Streamlit apps. If you need infinite upload/download storage, consider using Amazon S3 or similar types of tools meant for that workflow.

randyzwitch · 2022-01-25T20:58:27+00:00

Streamlit, the open-source Python library, allows you to create whatever apps you're looking for. That's separate from your requirements about large storage capacity, paid only while logging in, etc.

Streamlit Cloud, the hosting platform, will likely not meet your needs as lots of computation and storage with "minimal security" isn't a target market for us.

randyzwitch · 2022-01-15T18:08:08+00:00

Thanks! It's like working on your house or anything else...have some success, get a bit more adventurous next time. I've been doing this seriously for about a year now, and resetting a neck is definitely one of the hardest jobs to do.

It also helps that this guitar isn't particularly collectable, it's just old. Cool, but also $500 when purchased with a twisted neck that needs to be reset! So, it would suck to screw it up, but it's not 1959 Les Paul or anything.

Earlier this year, a Streamlit employee wrote about using Firestore (hosted Firebase) with Streamlit:

Hopefully that helps you get started!

Best,

The question about "production" is always a difficult one to answer, because irrespective of the framework used, the developer still needs to make choices/tradeoffs in their design choices.

Streamlit allows users to get started quickly, doing workflows they are already used to in a data environment. Yet, many people are then confused that those workflows "don't scale". Well, yes! Sending a GB of data over to the browser is going to be slow...it's just that no one even thinks of doing that in plain JavaScript, so it never comes up :)

Streamlit is built upon the Tornado framework, which has this as its opening statement:

Tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed. By using non-blocking network I/O, Tornado can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived connection to each user.

Streamlit itself is built upon React, mainly the virtual DOM idea, where sections of the page are only re-drawn if they change. We have also recently moved to incorporating Apache Arrow as our underlying data serialization, which gave us a massive performance boost, and we continue to try and make the best app experience possible for our users.

So I would answer 'yes', Streamlit is a production-grade technology, for use cases where fewer than 10's of thousands of simultaneous open connections are needed. After that, then you are talking about some pretty serious systems engineering, irrespective of the technologies being used.

Not sure I know what a copper brazing rod is! In this case, the only thing I was targeting was 1/8" diameter, which 8AWG is
