Whatever you do, be careful using channel locks on the base! I crushed my rm1 base after months of use cause I tightened it down too tight. My current rm2 on my grand I tightened too much, used channels to get that top off, and marred the base up in doing so.

The damage is minor, but it's there none the less. I know one day I'm gonna destroy this poor thing, hence why I have a rm2 backup that I ordered. Can never have too many backups....
