The First Step

Well, this is the first blog in the first step to making a complete CSM. After many conversations, material research, and reverse engineering, we are on our way to making our first prototype of a CSM. The material we are using is an aircraft grade aluminum (6061T6). Each part is being turned on a CNC machining center, so the tolerances are very tight. We are taking each part at a time and trying to machine it as close to the original as we can. At this point we have the needle cylinder turned without the slotting operation, the cam shell turned without the radius milled and the bed plate is completed. The bevel gear is turned, but does not have teeth on it yet. I will try to post updates as we get farther in the process. Please do not hesitate to email us at Erlbacher Gear and Machine at sales@erlbachergear.com.

This is exciting! I've got a couple of Gearharts, from the 1920's, so between the two of them I've got two different ribber styles and miscellaneous accessories, along with the original cast iron stand. If you need to borrow anything to measure, or pics of anything I might have, just let me know.

Where in MO are you located?

I'm an old Marine [70] and Nam vet [68] in WI/NY/AZ and I like knitting wool socks for some of my friends that hunt. Some have diabetes and can't find proper fitting wool socks.

As noted above, if you need any parts, etc that I have to measure I'd be happy to drop them off when I visit my friend in Joplin.

American manufacturing! I love it!

I am sooooooo excited! I have a 1914 Gearhart. Which model(s) are you reproducing? Whatever you do, please please maintain the spring loaded cams!!! Their "clicking" sound is wonderfully soothing and it's nice to be able to listen for the click when doing heels and toes. The sound confirms that the cam has cleared the needle butt when cranking in reverse.

I've bookmarked your blog and will be blissfully watching and waiting. I gladly offer my assistance to you with this task.

Estoy escribiendo desde España. No había visto nunca este tipo de máquinas. ¿Van a producir en serie las tricotosas circulares? si es así, por favor quisiera me enviaran información.
Sorry for my poor English. I dont know this circular machines. Do you develop the CSM for sales? Please I would like your information. Thanks in advance and bes regards,
Roncesvalles

Weeeee....How exciting and interesting!!! I have 5 CSMs, but not a Gearhart. Looking forward to watching/reading about all your progress.
hmmmm I just might have to get one in Hot Pink...lol.

Your fine machining nearly took my breath away....when looking over all your work with gears I am confident this Erlbacher Gearhart will be a smooth machine to crank socks on. This is so encouraging for all sock crankers....Thank You
