In a real pickle this weekend.

My new 430 RDM would not come apart despite multiple attempts. only managed to get it out around 1cm but that was it. It wouldnt move any more.

Tried the following:

- Six guys either side pulling and twisting (thats how I got it the 1cm) We also used a rubber gripping tool that plumbers use and that almost broke.
- Double boom technique - boom grips slipped.
- some WD40 into the join - didnt seem to have an effect at all.

Need some advice what else to try before I take it back to the store for an exchange.
