    How to loctite 2mm (0.078) wire to shaft drilled for 4.75mm?

    I heard some of you guys loctite a few tubes to fill in the space to get a 4.75mm shaft to attach a 2mm (0.078) wire...

    What size of tubes should I use for this? Would it be a good idea to do this on the collet side as well?

    Figured I might do that for the collet too... instead of buying a 2mm clutch, as I have 4.75mm MBP collets which I thought I'd make use of instead...

      good luck finding metric tubes. Probbaly better off getitng someone to make a step down insert

          Is it actually metric or .078"? If it is .078 then try k&s tubing. Terry Davis would know more.

              You guys know of anyone who can make a step down insert?

                  4.75 mm is .1870079 inches so that is 3/16th of an inch so tube may work

                      Will brass tubing be strong enough?

                      Man... Jeff wolt is supposed to a pro with this stuff. Can't seem to get ahold of him though.

                          If you cant get hold of Jeff wohlt OSE has .078" wire drive to 3/16" stub x 16" long, the OSE ones are made by Wohlt.

                              I have used K&S brass tubing one inside the other for stuffing tubes in the past, but each sliding fit tube can introduce eccentricity and angular misalignment especially with short lengths. I wouldn't use that method on a stub and expect the wire to last long, if it is not perfectly aligned it will break at the nose of the stub.

                              I would just but a 2mm stub shaft, it will be much cheaper than several brass tubes if you don't have them already and will better alignment.

                                  Paul: Hmm... yea thats what I was thinking. Would you recommend getting some sort of stub adapter for a .187 collet to grip to as well? I have some decent MBP ones, figured they'd work better or as good as the 2mm MBP clutches.

                                  I was initially thinking about using 2.5mm or 0.093 wire though but it's too bad OSE doesn't carry MBP clutch sizes for this.
                                  So I guess I'll try the 2mm first. Hopefully it doesn't break my new LMT motors in case the wire snaps from the load...

                                  Do you guys think 2mm/0.078 wire would be strong enough to handle 65k rpm spinning something like an x447 prop (twin) ?
