I have actually thought of starting an LLC but wouldn't I need insurance too? I've decided to just buy equipment and maybe rent something to supplement.
You may want to seek some legal advice on the insurance issue and LLC. If you are completely secluded and there's no chance of causing damage or injury to others while operating the machinery, the risk would/could be minimal. Although, if your property is somewhat accessible, the machinery and even your project could create an "attractive nuisance" for nearby kids, thrill seekers, etc., or bystanders around while working the area? If the LLC is responsible for any injuries or damages to others, here's where I would think you would want to be sure you have insurance protection/coverage for the LLC.
If the equipment is owned (or rented) by you personally, your personal liability coverage under your Homeowners policy should provide coverage should an incident occur (Bodily Injury or Property Damage to others). Check with your insurer to confirm. And if the equipment and job is being done personally, do you have a Personal Liability Umbrella Policy? If not, I would certainly look into one as they're very inexpensive and provide excess liability protection of $1m or more although, would likely not provide coverage under a LLC.
Few people should be without an Umbrella Policy!
Lastly, if you rent any equipment be sure there's insurance coverage for damage (including theft).
Good luck with your project and please share the experience with us as stated in above posts!
