I'm trying to add a drain to the pan of a used Lortone Max-8 arbor that I just bought. Someone bored a 3/4" hole in the bottom of the sheet metal pan. The easiest would be to weld on a tube, but don't have welding ability. I don't want something that sticks too high up, or there will always be a quantity of water in the pan. The drawing below shows a couple of solutions. The one on the right represents a nylon fitting I bought, but the threads taper slightly & I couldn't find a nut that fits it anyway. If I find the right nut, I will cut off the protruding threads above the nut. I need a tube with a thin flanged lip, with threads up to that lip & a nut that fits those threads. Even if it doesn't have the barbs, I could make that work. Any ideas? Lynn

Could you just drill a hole right above the jamnut to reduce the depth of the water ? You could drill mulitples around the diameter to get good flow. Might clog easy but as long as its any easy spot to poke something through it wouldnt be too bad and its a quick solution. Chuck Attachments:

You could always enlarge the hole and use a sink drain. They fit almost flush, and come with the nut and washer.

I've made a couple drains by drilling a hole through a flat head screw, then tapping the screw down in a hole in the sheet metal until the top of the screw is flush with the original sheetmetal pan. A piece of pipe with a bore about the size of the screw head held underneath prevents excessive distortion of the pan. Then screw on a piece of hose to the screw threads. Another option would be an elevator bolt; large diameter, flat head. Hold the bolt with a washer and nut, seal w/silicone.

I always use bulkheads. You can find them on any aquarium supply site or eBay. Scott

Lynn: You could drill a hole the diameter of a piece of copper tubing, form a dimple around the hole, flare the tubing, and solder it in. That is what I did on the super grinder. Use an acid flux, and it will work pretty good if you tin both tubing, and hole, then put them together and give it some heat. You can form the dimple with a large flat head bolt.
