    Your 2 gallon will not work at all. You generally need about 15 CFM (varies with tip size). Most household 5HP compressors will really struggle with a blaster. I would say that is an absolute minimum.

    I think it's around $100 day here for a tow behind, or what I do is rent it for the weekend at a discounted rate.

    Our local rent-all place will work a pretty sweet deal for a weekend. Maybe yours will as well. This would give more time so as not to be rushed.

    Please be aware sandblasting is NOT operator friendly. A sealed, pressurized helmet/mask is really the only way to make sure the dust from the operation and the residue being removed stays out of your lungs. Silica sand, I.E. glass, once in your lungs will never come out. Silicosis=big problems! And don't forget ear protection-- my uncle is profoundly hard of hearing from sandblasting as a young man.

    It is a HUGE waste of time to do LARGE items yourself.
    Ask me how I know!

    Conversely, it is a BIG WIN to do smalls your self.

    I have a Media Blast and Abrasives VIPER glass bead blast
    cabinet for smalls, and I will NEVER be w/o such a tool ever again.

    I tried the large item thing and I was successful but when
    it is all said and done you WILL be dollars ahead to farm
    it out.
    VERIFY true everything I say/suggest, ALWAYS. Do NOT take my word as Gospel.
    I have been know to make mistakes! Believe it!

    The size of the compressor is directly related to how fast you can clean things. Smaller compressors will not be sufficient for some thing like a bed. I do commercial blasting and an I run a 100HP Ingersoll Rand diesel unit. I blast with a #6 nozzle that's a 3/8" bore and uses about 250CFM of air. I would suggest you find a local commercial blaster and have them do it. By the time you rent a unit and buy sand you will not be money ahead. Commercial blasters buy sand by the ton and its much cheaper. I buy it by the tanker load which is 26 tons and its pumped into a silo. My blast pot holds 6,000 lbs of sand so I can blast non stop for about 6 hrs.

    I have been going through the same thought process. Researching blasters, and compressors. I am a DIY guy. I swear sometimes I will work 40 hours and spend $2000, so I don't have to spend $2500 letting someone else do it.

    Learn the hard way I guess.

    I have given up on the DIY blasting for big projects. I will sub it out. Not worth the time or hassle. Plus I'll likely get a much better job letting a pro do it as opposed to me learning how to do it.

    Just a heads up, those dustless blasting systems are absolute garbage. They know how to use the hype train to get people stoked on a ****ty product. I've worked for Graco and I've used the EcoQuip vapor blasting units, they are much more efficient, use considerably less media and it's a very green to use for the environment. So yeah, if you want more info I would suggest digging in to vapor blasting. It's amazing.
