YES...better yet... IF YOU HAVE THE TECHNOLOGY This geargenetator.com script only runs on-line can NOT be stowed locally on your PC AND the reason I went to the trouble of documenting : How to mark a gear to cut teeth ....any size... any number of teeth http://www.learnmorsecode.com/gears/index.html was because some of us have really bad internet connections that will not be getting any better any time soon so PDFs and bigger better faster complicated javascripts running server side calculations and YOUTUBE videos are off limits to these guys..... soooo drop back and punt.... go old school an show how to to it with a $10 calculator and a pencil. I AM NOT a mathematician. But a mathematician made a YOUTUBE video showing SIN(DEG/2)2 read as: SIN of (degrees divided by 2) times 2 will yield a number that you multiply the circle radius and have the distance to mark on whatever you are cutting... metal..plastic.... and I thought it would be best to know this method and share it.

Rob, Unfortunately, knowing the spacing of the gear teeth is only the beginning of cutting gears. After I looked at the geargenerator website, I realized that it had terms that were undefined, and as a layman, I could not use that site. I found the definitions of the terms in the Nomenclature section: https://en.wikipedia.org/wiki/Gear At that point, I decided that designing gears was above my pay grade, and went back to searching for ready made metal gears. This is less difficult, if you can find gear sets having the same diameters and number of teeth as your original set. The gears don't have to be identical to your original gears, they just have to fit the space and mesh. The problem that I have encountered is that I have found a gear set that almost meets that description, and it is difficult, without physically trying the fit, to determine if there is enough slop in the fit to allow them to mesh with the existing shaft spacing. The reason that the diameters have to match the existing gears in the HF laminator, is that the motor gear drives one of the roller gears, which drives the other. This is a hard mount, with no springs. This means that there is no adjustment available between them. The motor position has some small degree of adjustability, but if the roller gears don't mesh properly, the game is over. I am still looking to find the time to determine whether the plastic structure that supports the roller bearings can take temperatures over 200�C for extended periods of time. Harvey

I ran into this very same issue. I did not have any gear making tools here set up that could just knock out a metal gear and slip onto the motor D shaft. After week of searching the internet I concluded that there was not any instant source to replace my plastic gears unless I wanted to pay $75 for a custom made gear. http://www.learnmorsecode.com/laminator/slowmotor.jpg So I resorted to RC car gear suppliers and bought a pile of nearly acceptable gears. I say nearly because I will have to drill out the smaller shaft holes to fit the lamnator. As far as designing gears being above your pay grade goes..... We are pushing rollers in a laminator. We don't care if we don't get it perfectly right. Look up gear making on the web and you find guys making gears out of plywood and guy making gears with hand tools.

Yes... thanks for the tip. I concluded that if I did not find I perfect match there I would definitely find something close...or close enough. My interest in learning how to make a gear from scratch is driven by a number of projects that I thought I would to get into some day but I was missing the gears. http://www.learnmorsecode.com/regen/coilwinder/coilwindervintage.gif I will post a soup to nuts home brew gear INSTRUCTABLE when I get to actually cut some gears but I am not well enough to work with sharp tools right now. I got sick two days before Christmas. The bruise on my right hand in the pictures is from an IV needle. On 01/07/2017 06:49 PM, Harvey Altstadter hrconsult@... [Homebrew_PCBs] wrote:

Just a thought.......have you checked for gear sets from RC Model car and hobby robotics suppliers?
Re: [Homebrew_PCBs] How to mark a gear to cut teeth ....any size offline

YES They use a much thinner axle so it is possible to use those gears if you can drill out the hole or file it into a D shape. On 01/08/2017 04:37 AM, Howard Chester howard.chester@... [Homebrew_PCBs] wrote:
