What is the best adhesive for reattaching Velcro and or foam to sanding discs? What’s a good source of replacement foam for discs?

Sanding Disc Adhesive

I have purchased both 2" & 3" foam pads from Amazon. Probably not the best quality, but the price was right and the purchase easy enough.

I have used 3M spray adhesive, with mixed and messy results. I have also purchased replacement Velcro pads (no spraying of adhesive) from Vince Welch. Here is a link Replacement Velcro pads.
I have also found that keeping the sander and lathe running at slower speeds (less heat build up) tends to keep the Velcro pads in use much longer.

Woodturners Wonders has repair discs, but it looks like they just sell in a kit with several 2" and 3" Velcros. Good if you need to do a bunch. They're sticky-backed. I have only used these a couple of times.
When I repair mine, I usually just go to the craft or fabric store and find or sheets or 2" velcro rolls (if you find it, they should sell it by the foot, or whatever will work). Use contact cement to stick it on and trim it to size.
Steve Worcester has a short writeup on replacing velcro.
Also, get some protective pads (the orange ones on that page, or something similar from someone else), their purpose is so you wear them out instead of the mandrel.

I have also used contact cement, which I think was recommended by one of the sanding materials retailers.

3M 90 Industrial High Strength Spray Adhesive is really strong stuff. It's much more robust than 3M 77 Spray adhesive. They say that it is for industrial use only, but you can easily get it online. The best price is $12.98 at Home Depot.
If you are making minor repairs, contact cement seems to be a good solution. I damaged one of my sanding discs and found this video very helpful.
Well, if the disc or foam is coming loose, to me, that is a good sign that it is worn out. Like Donna said, slow sanding speed, and slow lathe speed for sanding. To that I would add very light pressure. Getting the abrasives to cut is an experience. If you are spinning too fast, the abrasives don't get a chance to dig in and cut. If you are pushing too hard, and by that I mean that even the weight of the drill could be too much, then you generate heat, and that will make the glue holding the velcro or foam on come loose. I do have Barge Cement, which is a rubber cement, on hand, but as I said, if things are coming loose, time to get rid of it. For 'interface' pads, which are cheaper than the mandrill they go on, I prefer the ones from VinceswoodNwonders. I use firm discs up to 180 or 220, and love the one he has that has the 1/4 round profile on the edge. I use medium pads up to 400. If I go over that, I go to the soft pads.

This velcro repair onto foam has been discussed a few times, and what I recall did work well was SHOE GOO, maybe it is still the best glue for this ??.
And yes I learned the hard way a long time ago that high speed and pressure did ruin the sanding disks and paper as well, slow it down and decrease or better no pressure, will speed up the sanding and prolong the disk and paper.

I would also say contact cement. You want the full fume (solvent) kind, not water based. Stick on velcro is going to be hit or miss depending on what exactly you are sticking the sticky side too. They have several different adhesive types.
