So, this is my quandary which led me to discover this forum originally!
I bought a few electroplated coarse discs and (aluminum)backings for my 8" Hi-Tech slant polisher after realizing the HT machine didn't include anything coarser than 180. Having sticker shock at the price for individual discs and base plates etc from HT's site, this I purchased them from Amazon instead not even considering that they didn't come with adhesive backing. Oops.
Does anyone have experience gluing their own lap discs to the back plates? What product do you find works best for adhering to aluminum back plate and to acrylic plate? I was thinking a high-tack adhesive spray but not sure. Anything finicky I should be aware of in the process?
TLDR; What adhesive works best to stick metal discs to aluminum back plates?
Thanks in advance from a newbie!

Does the Hi-Tech unit require that metal diamond disks to be glued to a backing plate? I have an Ameritool flat lap and I simply swap diamond disks that just sit on a single base plate. Both the disk and the base plate are held down by the threaded knob.
Is there something about the Hi-Tech unit that would prevent that?

I couldn't find anywhere they said NOT to use the diamond discs without sticking the backing. I suppose I assumed it was necessary because their #180 came together already as a lap and they seem to really push the adhesive treated discs on the site. Edit: Seems like maybe the most economical thing is to get a bushing and make a master backing plate (HT Slant cabber didn't come with a bushing but looks like they sell one). Though still curious if anyone has glued back plates.  |

Though still curious if anyone has glued back plates. Granted I have a flat lap from Hi Tech but I have an extra backing plate that is unglued and I use it to swap out different diamond grits before going to the smoothing plates. Now, I do have the smoothing plates stuck to the backers because I use the sponge attachment to smooth out the polish without faceting but I never tried a smoothing plate without it being stuck. It's all about how well it adheres to the arbor I guess. - Rob |

And luckily the smoothing discs did not already come attached to the included backing plates. I hear removing them is a blast. |

One is where you stick metal disks to the acrylic backs directly as self standing units for each grit (each having their own acrylic fixed back I mean). But then if you look at their Glass/Crystal model (as opposed to the rock/mineral one) you get a master acrylic back with 3 thin metal diamond discs that just sit on the master using a little bushing. And you just swop out the discs which are held on with the threaded knob. |

And if you wanted to stick a non-glued metal grinding diamond disc to an acrylic back, something as simple as 3M double sided tape should work quite fine! I have used that method to make a leather polishing disc.
