I doubt this is practical for what little you'd need one B, but that Milwaukie electric grease gun is the shcit. I bought the locking tip for mine so I didn't have to hold it. For the excavator you have to grease the house while sitting inside and spinning the house around while you squeeze the trigger. Couldn't do it from inside w/o the locking tip and electric gun. The side benefit is having other milwaukie battery tools makes sense once you have the first one. Man they are nice
