Great idea on this. I never thought of using an old kitchen sink for the funnel. I'm gathering pieces to make one of these. I'm using a 50 Lbs. out of date propane tank that I came across a while ago. The thread in the top of the tank is 3/4 inch pipe. I have taken a 20 Lbs propane tank and cut it in half to use for the funnel. I did have a thought that maybe the dia. of isn't big enough to catch the arc of the oil as it comes flying out of the oil pan, but I also think I can raise it high enough under the stream to catch it until it settles down and straightens out. I actually have a single sink that I could use, but that was planned for a parts washing station, we'll see. I planned on using a 1/2 inch black pipe as the upright pipe to drain the oil, but haven't actually tested yet to see if it will fit inside a 3/4 that will screw into the top of the holding tank. Does the 1/2 inch pipe provide enough flow for the oil, or does the oil ever back up into the sink as it's draining? What would you change on the design of yours?
Yes there is mild backup during an oil change. However it's not a problem because the sink only fills up a couple of inches until the vehicle drains out and then in another maybe 45 seconds the sink drains down. The only thing I would change if I had to do it over again would be to use a shorter tank then the upright tank I currently have. I would still use an upright tank but would like to get one that's about a foot shorter. The geometry of what I built barely fits under my inground scissor hoist for low vehicles. It's definitely workable but that's what I would do differently next time. Also I would put four rotating casters on each Corner instead of the two fixed casters. Very often I want to move the machine to the side or forward backward and the fix casters make this less efficient.
@@mrdiyguy123 OK, thanks for that. I have a 2 post hoist going in my shop, so I don't think that height will be an issue for my set up. I have bought a furniture dolly that is about 16"x16" square with a swivel caster at each corner for the lower tank to be attached to.
Take it to the next step just find a vacuum pump Unless you have one for A/C work or air operated venturi vacuum generator and pull a vacuum on your tank, connect a hose with a valve on the suction end to a tee under the valve where your overhead drain tank is dumped in and vacuum your oil in. May want to change your Guage to a vacuum/pressure gauge

I believe it is imperative that from now on your shorts MUST match the equipment you are DIYing on/with/to.
