Q:Does anyone know how to effectively level the ground before laying an above ground swimming pool?
Sand is the thing. get a load delivered. It's easy to move and level with a rake or shovel.
Q:is the Barska Excavator a good scope?
I'd do as the other answerer said and pay just a tiny bit more to get a Nikon, or other quality brand. Barska is a third rate scope manufacturer.
Q:How painful is a filling?
It doesn't. They numb you. You will feel a pinch on the gums when the needle goes in, and this doesn't hurt at all. It's about half a bee sting.
Q:how do you set the time clock on kobelco excavators?
I do not have a kobelco excavator and the dealer ought to have the answer to this question.
Q:when it comes to building a house....?
owning the lot already is a huge savings. doing some of the work yourself is extremely helpful at lowering the cost, your not paying for all the labor. if your going with a builder, you need to ask if its ok if you can do some things yourself, many wont let you. what you might have to do is be your own contractor, and subcontract out the excavating, like the person you know, but you would need to check with all of the codes and get up to date on how that all works, if you need any special license to do that. like with the electric, you can do it, if you have it inspected. you would be surprised at how much you can save just even doing the finishing work yourself, like cabinets, floors, lighting, hanging the doors, fixtures, installing the shower, toilets, etc. some builders will basically bring the house to drywall, building the shell, and you can do the rest. a friend of ours is helping on his house and he cut at least 60,000+ off his price. as far as wood being cheaper than carpet, i would say not. but it all depends on which you choose and who you have install it. if you do wood floors, you can do that yourself and will save huge, and its easy, unless you lay carpet professionally i wouldnt go there, its worth having that done..
Q:what type of grease gun should I buy to grease excavator tracks?
A regular sized one will do just fine. You know...the one that uses tubes of grease about the size of a tube of bathroom caulk. I'd get one with a flexible hose as opposed to a fixed one. That way, you'll be able to get to the tough ones without having to maneuver the machine as much.
Q:10 points for math help??
10 points for John D
Q:Has anyone tried the excavator substrate? I'm thinking about trying it with my bearded dragons....?
What in the world is an excavator substrate?!
Q:hi,does anyone know how to find excavator driving jobs in canada,i am a qualified operator of 15yrs?

Q:What is The Transformer?
That one you described he is called Demolishor and his vehicle mode are excavator and one big unicycle.
