Thanks guys. I am probably making this more complicated than I need to. I have a tendency to do so. My build will start this week or next. The tank is on its way according to Northem Tool. The pump got delivered yesterday from amazon but appear to have been opened and used, took that as a warning it might be a dud and sent it back. Decided to upgrade to the 3 GPM on the replacement.

Started the build. Took apart an Scott's Elite Spreader that I never saw eye to eye with. I hated that thing from day one, but the tires arnt bad so hopefully it can handle the weight. Ging to clean it up and give it a paint job. There is no flat surface for the tank to sit on, so I am going to have to come up with a plan. I have some ideas but will probably meander around Home Depot for an hour or so tomorrow to come up with something. Meanwhile, I did the plumbing on the tank. The 3 GPM Everflow is larger than the 1 gpm or 2.2 gpm pumps that I think this tank was intended for so positioning it with the mounting holes while still getting the fittings in the molded area was a little bit of a challenge, but I think this setup works just fine. I really can't take much credit at all on figuring out the parts, I basically copied the list from @wardconnor. I hope the links in the spReadsheet earned you some commish, you certainly saved me plenty of delays, frustration, and costs. Thanks man!





I ended up ordering a 12v 18ah battery off amazon, but also got the needed parts to try out hooking up my dewalt 20v tool batteries. If that works, I will post how I did it here. If it doesn't, I will scrub all evidence of my failure from this thread.

Ok this is pretty cool. I got a temp set up going to try my tool batteries and the results were great. I filled the tank to 8 gallons on my sprayer and hooked up the 3 nozzle boom. Using a fully charged 4.0 ah battery I was able to spray the whole tank and I still have a full 3 bars on the battery.

Here are the parts I used if anyone cares:
Dewalt Battery Adapter: https://www.amazon.com/gp/product/B07HKGM78H/
10A Step Down to 12v: https://www.amazon.com/gp/product/B07V6X6L89
Also got a SAE Connector locally at AutoZone. Its really cheap (it was $2) and is only 18 gauge wire. I'm going to order one of higher quality for the install

My plan is to make some sort of unit to install all of this on to keep it neat. Ill also see if I can figure out some way to protect the battery from getting any chemicals on it.

That's awesome! Great idea, and nice job getting the right parts working together. I'd bet most if not all of us have a cordless tool system already, and i've seen that type of adapter for other brands. :thumbup:

Edit: as for protecting the battery and converter, you could maybe use a small plastic ammo can like this, or some other kind of similar gasketed box. https://www.amazon.com/dp/B005IURN5M/ref=cm_sw_r_other_apa_i_i.J.EbW3BD90C

@ScottieBones that's a good idea. I was thinking an outdoor electrical junction box of some sort, but was questioning if I could find one large enough for the battery. Your idea might be better because even if I found one large enough, most I have seen are secured using screws and not meant for quick access, which would be something else I would need to come up with a solution for.

yeah, I have a couple of those around the house and they are pretty light weight, and would be simple to run wiring into. The lids are quick and easy too.

Do you think this tank would work for a similar build? Hard to tell the shape of it based on the technical drawing.

I think that would work nicely. It looks to have about a 6.25" x 4.5" X 0.625" sump with the 3/4 drain on the bottom. This sort of configuration is likely to make it easier to drain the tank completely (as opposed to the more typical pickup tube). I recently rebuilt my sprayer using a cone-bottom tank, which was kind of a pain to mount, but it works great (also made by Ace-Roto, seems to be good build quality). What you found should be much more straight forward to mount. lol

i found some images on an amazon listing for hte tank: https://www.amazon.com/Ace-Roto-Mold-Rectangular-Applicator-SP0012-RT/dp/B00QB0O784
looks like a really small sump area. it would work, but since the tank will be moving around when you use it, liquid may not settle there very easily

Sorry I don't really have anymore right now. Won't have any for a few weeks.

Here's. Video of me using it.

You are going to want a 2+ gal/min pump for 2 or 3 nozzles like is on the 21 and 31 gallon Northstar tow behinds.
