Yes
Fancy having a go at it and I'm after advice on what shade would best, there are 8-13 shades on eBay for about £2

I was thinking of using superglue to attach it to a uv filter, how have you guys done it?

Or would I be better getting a nd filter but which grade is similar to welding glass?

There's a *massive* thread on this topic, full of advice and links to advice on using welding glass..
 
Dont use super glue. It expands and contracts at different rates to the metal filter holder and could crack with temperature fluctuations (like taking it from a warm house to cold outside), I used an opaque silicone sealer.
 
I superglued mine to a uv filter. Not used it yet but I'll report back when I have
 
I jammed mine in a HK ebay cokin p filter holder, then taped the edges and it attaches to a lens with a cheap adaptor
 
I used blutac to hold a filter ring to the glass. Works well and can be removed, if I want.

+1 - that's what I did before getting some cheap screw fit ND filters :)

Welding glass works fine but you need to make sure to adjust the WB properly.

Many anglers have no problems using super glue to make up their traces for Carp/sea fishing.
These rigs can contain all types of materials from metal, nylon, braid, plastic and rubber.
Once cast into the lake/sea they perform O.K. and have no problems with the instant change in temperature.
 
I bought a filter step up ring to attach my welding glass to, cost me about 2 quid

Well feel free to risk it but I've seen car windscreens crack before where the rear view mirror has been superglued on. Also by using a sealer rather than glue you can ensure a light tight seal.
