We all know a slide hammer is a great tool to have around the shop.  The problem with the commercially made units are that they're expensive and not terribly versatile.  I didn't want to buy 3 or 4 hammers for various purposes.  So I set out to design a slide hammer that could do both light and heavy jobs, as well as have exchangeable tips so I could build different tools for the end.

Step 1: Gather up the pieces

I rummaged through my scrap metal pile and here are the parts I used to create the tool.  There is a 1/2 inch smooth rod about 18" long, a large bolt, two nuts that fit on the bolt, a block of steel with a hole drilled through the center, and a large chunk of round stock.  Missing are a few nuts and a bolt I use on the rod, you'll see in them in the next step.  All pretty random pieces I suppose... not exactly the project you can run down to the hardware store and collect everything, so I do apologize for that.  These are all pieces I've picked up along the way, it's more of the idea I wanted to share in this instructable.

Step 2: Weld up the parts

Here are the pieces all welded together.  I'm not the best welder as far as beauty is concerned, but they're all together.  One piece is just the large bolt welded to the heavy chunk of round stock.  The square block gets the rod run through the center of it and the two large nuts welded on top.  While welding the nuts onto the block I had the bolt threaded through the nuts to ensure alignment.  The rod itself gets a welded nut at each end, one to serve as the stop for the slide, and the other is a fine threaded nut that serves as a connector to allow for different tips. 

Step 3: Assemble

Here it is all assembled.  This is a dual weight slide hammer.  So if I need to only use very light force I don't have to screw in the addition of the large bolt and weight.

A slide hammer is a tool used to pull on an object when no leverage is achievable. In the automotive trades it's used for pulling dents out of sheet metal or to remove a bearing race from an axle, for example. Around the home one could use it to pull nails or metal stakes out of the ground, etc. What makes my design unique is the overall flexibility to add or subtract weight and/or length; and the ability to hammer on it from the opposite direction. Hope this answers your question.
