Default How to Add Dome to a Disc

I've already posted this, but thought it would be good in its own thread.

Backstory: I had an ESP Nuke that was STUPID flat on the top and has a low PLH, creating this awkward, hard edge, Vulcan-like shoulder, which I wanted it to be more round and grippy..

Here's what you need:

1) A small flower pot or something that the disc JUST sticks over from by about half an inch all the way around, so that the surface of the pot, or can, or whatever, is in contact with the disc right in the middle of the rim when the disc is upside down on it.

A paint can works really well, too, and is the perfect size.
Note: It also leaves a very small, Pulse-like groove that's not that noticeable and some people may like..

2) Weights: 4 2.5lb dumbell weights, and a 10lb weight.
(More or less weight is optional, but the above works well on star/ESP. I would assume less weight might be better for lower grade plastics..)

Others have mentioned a bowling ball as an alternative to weights.
Also, the water will rust your weights, whether you care or not..

Instructions:

In a sink, (or ideally a wash basin) fill the disc with piping hot water while it is upside down and centered on the pot or can.
(boiling the water is not that necessary but may help a little)

Center your 2.5 lb weights on the disc while it is filled with the hot water.

Add the 10lb weight to the top of those weights and let it sit for 10-15 minutes.

Optional: you can push down on the 10 lb weight while pulling up on the rim at the same time if you want to work the PLH down a bit and stretch the plastic a little, rotating your pulls around the disc evenly.

Every 10-15 minutes remove the weights and add hot water again, just like when you flatten a disc.

Repeat this process 4 or 5 times, then let the weights sit on the disc for a much longer time, left alone. (overnight or for an hour, your choice)

What you will end up with is a nice even dome that's a few millimeters more than what you started with. If it's too much dome, you can flatten it, or just know that it'll "settle" a little with use or as it slowly goes back to its original form. If it's not enough dome, use more weight or give it more time to sit and stretch / work the shape into "memory".

This method works awesome for me, and turned a "backup" / practice disc into a useable, nice feeling bag disc.

Note: The dome will not be a perfectly round dome, but slightly flat at the top, because you're using a flat weight.

OK. That makes sense. I was thinking, why not just buy a more domey disc?

You can just put a disc upside-down on a cookie sheet and overfill it with super hot water til it overflows and fills the cookie sheet up to the rim of the disc, and then let it cool all the way down.

Will restore some discs to their natural domey state.
