Nearest Horror Freight is a couple hundred miles south.  I've written them several times about how many people would frequent one here.  They always write back and suggest ones 500+ miles away in Detroit or thereabou ts.  I save the coupons and use them on trips or the occasiona l online order.

We've slowly downsized our livestock to a horse (looking for a good home for Josie) and just cleaned about 40 years worth of junk out of one end of a 24x48' barn after putting up a wall (wrong order).  A new floor, some insulatio n, a stack of drywall.. .  Need to fill it with something, the Maslow looks lonely.

Mark, what kind of metal bender do you have?  Looks like I may have some new shop space to fill soon.

Kirk

It's an el-cheapo Harbor Freight bender.  The fancy scrolls are done with their scroll attachmen t usually not available in-store, you have to order on-line.  Do you have Harbor Freight stores way up there where the cold air comes from?

You have shop space to fill?  I wish I could buy "shop space" but that would involve real estate which ain't gonna happen.

I needed something to test my newly construct ed roller chain drawbot style 4x8' CNC machine.  What better than an 8" diameter Gearotic gear?  The tabs worked perfectly Smiley  Otherwise I think mine still needs some more calibrati on, and the firmware (under active developme nt; it's complicat ed math, a servo made with brushed essential ly winshield wiper motors with worm gear reduction and an 8192 count optical encoder)  is still a work in progress.  It's within a sixteenth tooth to opposite tooth, not so much for the circle spokes. Otherwise, well, it's a Charlie Brown Special.

It's on the new wall of shame, at least until that wall of my long talked about 20x24' shop space gets insulatio n and drywall.  Can't wait until the 4' diameter kinetic sculpture .

the book is "Architect ure - residenti al drawing an design" by Clois E. Kicklight er copyright 1976.

I've used it hundreds of times to find the "standard" design for the angle on the back of a chair or the working triangle of and effective kitchen, acceptabl e rise and run on stairs, etc. etc..  Its always been personal stuff but very useful.
My $5 used copy of the 1981 edition arrived today.  Not sure the chapter on T squares and erasing (still remember those...) is too useful, but the standard dimension s, room sizes, beam loading, etc. is what I needed.  Thanks for the reference!

My middle girl has a Masters of Architect ure from MIT, but when I've asked her these kinds of questions she just tells me that's for the engineer to worry about.  Scary.

Mark;

 Flourish looks awesome,  I'm sure it will enhance the look of your pantry doors. Anyhow glad to know I'm not the only one that keeps his wife frowning. .
Thanks for sharing, nicely done.

Hi
For me I'd start to visualise what you want your clock to look like. Remember that most clocks are based upon similar factors i.e. an escape wheel, decide on what type you'd like here as this is an area you can go quite visule. You may need two or possibly three more wheels one of these to be used as the driving wheel.
Once you've visualise d your design perhaps draw a little sketch.

I'm designing a clock that only require three main wheels plus the motion work. The third wheel being the driving wheel where a counter balanced arm pulls the train very slightly as it doesn't take much force at all. The counter arm resets about every 20 degrees or so. This way you can play around with your design and have a bit of fun.

The important thing is getting the motion work to turn at the correct increment s. Gearotic has everythin g you need to get you there. Otherwise google known toothe counts for clocks there's many options. Once you have the wheel tooth and pinion counts use these in Gearotic to generate your clock, I started with my deadbeat escape wheel as I like to make these a focal point so mine is 100mm with a large span for the pallets. I also went for a large wheel diameter so the tooth counts stayed the same but I altered the module within Gearotic until I got what I wanted visually.

I found using Gearotic very useful and I have to say very good. You can use this to generate the file output you require , I used DXF. and then opened  this up in Fusion to manipulat e my design even further. I also have the benefit of a 3D printer so I'm proving the concept before going to laser print where I'll use a mix of Acrylic and Aluminium .

As art says play around with your design have a bit of fun if you like or just keep the design simple but remember the important thing is telling the time so the correct teeth counts are somewhere you ought to start looking in to.

Not much woodworki ng or CNC going on in the summer because I have to take advantage of the weather to do things outside, like welding.  My wife frowns on me bringing welding equipment into the house, especiall y in carpeted rooms.  I recently purchased a scroll attachmen t for my metal bender and made my first project which looks remarkabl y similar to something that Art's flourish module would generate.  Definitel y not random but a nice flourish that will enhance the look above our pantry sliding doors.  Photos show the generatio n and resulting flourish hanging on a shepherd hood while the paint is drying.  Please forgive this post if off topic, just thought it might be fun to see what people do when they take a break from "Gearotic".

Michael:

   A sense of humor is indispens able in such things. I dont think Ive ever
built anything in the process of which I haven't questione d my sanity. Building
a clock is a good way of learning your limitatio ns.. among many other things..

Dear Art
Thank you so much for detail explanati on and your uplifting sense of humour.
Hopefully, after few years I will have something to report about my plant stand or perhaps even about my newly build clock.
