I want to create a 4th axis for my gantry mill. I plan to use a 1:100 harmonic drive to directly turn the work piece. Aluminium is the hardest material I...
Will it unscrew? - yes Is it hard to make a cam lock spindle - yes Most useful - 4 jaw; most conveinient - 3 jaw; most versitile - faceplate; All depends on...
It has been suggested to use Molybdenum Disulphide, and PTFE mixed into epoxy for homemade moglice. I had a heck of a time getting the proportions right, but...
Where in the heck does one get molybdenum disulfide and PTFE in powder form? -- Phil Mattison http://www.ohmikron.com/ Motors::Drivers::Controllers::Software ...
... I've got several pounds of "virgin Teflon", ie. the stuff as it is scraped out of the pressure vessels where it is formed. it looks something like snow...
I think that they mean they will not sell more than 200 lbs online. It looks like they are happy to sell 1 lb for $42.50 online. Pete. ... From: Ralph Reese ...
For all of my Epoxy poweder additives I buy from Ebay.. I've used Alum powder in epoxy, looked the same as moglice but I doubt looks count for much :) Search...
Here is a source: http://www.sentrysolutions.com/BP2000.shtml I used to get some from a welding equipment supplier that was used to lubricate mig wire guide...
Amazing. Although for most folks it might be more attractive by the ounce. I guess I forgot that these days you can find anything via Google. Except maybe a...
Yeah, I've seen the patents! I've looked into a few other ones too. MoSO2 seems to be the key. So I've been thinking along the lines of: MoSO2 epoxyresin ...
I'd be careful w/ copper... there is the possibility of some form of electrolic reaction.. I've seen a big tank w/ suspended copper in an oil which eroded the...
... If you have even spoken to anyone who really knows the product that is patented, the patent is often wrong on purpose. the idea is not to devluge the...
ANY output would work. a pulse stream would be ideal, but just a voltage signal on the parallel couild would if there was a second line that showed above or ...
For most steper motors you can find a torque curve showing the available torque at different step rates. Depending on your setup you probably won't be able to...
Not sure if anyone has tried this one? www.david-laserscanner.com Quite interesting. Can be as simple as using a webcam and a laser level. Played with it very...
I heard a story about the 2,54 conversion factor. At the beginning of WWII there were three different conversions in use; the US used 2,54 plus a few...
I have seen some attachemnts to higher end CNC machines that use a cicrular saw. I am thinking of a 4 inch dia tube with belts inside. a pulley set at the...
Nice one Pete, that's made my day. Saved a bit of time too, I was going to have a hunt around for the exact conversion figure in a while, nice to know it's...
A further point of interest is that the 2.54 exact conversion factor allows a simple gear change to convert a imperial lathe to metric for thread cutting. The...
... Gaffa tape and jubilee clips :) Most 4th axis/rotary tables could be adapted to do the job but you would have to make it very high to get the center of the...
