[PSUBS-MAILIST] Cutting circlip grooves

[Alan James via Personal_Submersibles]

Thanks Brian, Hank.   They look an interesting supplier Brian. I will put them down on my list.Have visited a few places, but I mainly buy off the guy that sold me the lathe & milling machine.Have solved the problem of my chuck jaws being too small & are getting an adapter plate flown outso I can put a larger chuck on. Cheers Alan

Brian,no we don't have industrial areas in N.Z. , just grass with sheep & cows :)   I have a lathe & mill, but these grooves are particularly small & in stainless,so wanted a bit of advice before I attacked them.Cheers Alan

Alan,   Can't you go down to an industrial area of New Zealand and pick up some equipment , like laths and mills? Brian

Thanks Hank & Emile.That's a brilliant idea Hank. I have found a couple of diamond blades for a dremmel drillthat are thinner than my smallest groove; & standard dremmel disks that will do for thelarger of the two grooves. Am working on my brushless thruster & replacing the motors shaft with stainless, & extending &machining it to fit my propeller.Cheers Alan

Alan,If you have a parting tool, you can grind it to the thickness that you need, but wow that is thin. You will need to buy a grinding stone and a bench grinder for sharpening, if you haven't already.  You need a special stone for the harness of the cutters.   Your grinding disk idea is not bad, just take the disk and run a bolt and nut through the centre of the disk to hold it.  Then clamp the bolt in your tool holder, spin the lathe as fast as it will go and slowly push the disk into the shaft.  This is certainly not a standard idea, but us rookie machinists have creative licence to do  this.  :-)Hank

 Hi, I need to cut a few external circlip grooves in stainless 316 rod.One is 1.1mm wide (3/64") & the other .7mm (1/32") wide. The shaft is 10mm & 8mm diameter.I have a lathe tool that fits tungsten inserts & am wondering that IF I can get an insertthe right width, whether the tungsten would be too brittle for that.Another option may be a dremmel drill & disk if I can set it up on the lathe carriage & if they havegrinding disks that diameter.Any suggestions, comments appreciated.Thanks, Alan
