| Best adhesive to stick a magnet to a shaft - tacho project |
| << < (2/3) > >> |
| Charles:
Permabond have an article on the subject here http://www.permabond.com/2015/12/06/magnet-bonding-adhesives/ There adhesives can be purchased from glueonline.co.uk - no connection to either company The taco magnet on the shift of my mill is just stuck on with magnetism, has been OK up to 1800rpm |

--- Quote from: seadog on June 03, 2017, 02:23:52 PM ---I just popped mine on the shaft letting physics do the holding, I've not had a problem and have run it above 2000rpm. It depends on the diameter of the shaft. At a guess it's it's around 2-1/4" on my Boxford. --- End quote --- I have not used adhesive on my neo magnets BUT mine are on a flange on the outter side of the spidle AND max rpm is maybe 800 rpm. But this adhesive just saved me when a tube blew on my front tractor tire, I patched the tube mounted the tire and the tube leaked at the stem, removed the air put the ic-2000 on the crack and accelerator no leek and will fix later. Stronger than super glue types but high build up and some flexibility. AMAZON about $9/oz. ic-2000 rubber-toughened 1oz ca adhesive glue |

Thanks for the great replies - plenty of good ideas. Will probably upgrade the magnet that they supply with a neodymium magnet so mybe okay on its own or just with tape over Thanks Again for the replies |
