Introduction: MK: DIY Rebar Heart #ValentinesSpecial
I love to build theme projects. Halloween, Christmas and now the Valentine´s day. You say that you have noone to give it to? Well, there is love all around us, for example, love for making things, so lets get to it!
Materials: 10mm(3/8") rebar, welding stick, toluene and paper towels, clear lacquer.
Tools: vice, anglegrinder w/ cut off and wire brush disc, welding machine, shop torch, files.
Step 1: Preparation
I used rather old rebar so it was quite dirty and rusty (actually it was under water for several days, when my shop was under water during floods in 2013). I just used my angle grinder with whire brush wheel to clean it down. I really like to use the wire brush, because you can get in quite tight spots and it leaves nothing but metal and interesting finnish.
Step 2: Bending
First bend was done in the very middle of the rebar. I fixed it in my vice nice and secure and used my shop torch to heat it to red hot in a specific spot. Then I just bend it almost 180° and cooled it down in snow (one of few upsides of working in winter).
The second bend was a bit trickier than the first. I needed to make a curve on cca 15cm(6") and my torch isn´t enough to heat the whole part sufficiently so I had to cold work it. I fixed it in my vice again and used square tube as a prybar. This way it went relatively easily.
The third bend was even harder to pull off. Because I have already made bend #2 I couldn´t fit the piece in my vice, it just wasn´t big enough. I decided to screw the rebar down to my workbench instead. As you can see in the video I used several 6mm(1/4") wood screws. Then I used my square tube prybar once again. Because my workbench isn´t very heavy and it´s not mounted to the ground I had to push the prybar and simultaneously pull the bench and let me tell you, It was quite the workout!
Step 3: Welding
After all the work with bending I cut the ends so they would face each other. I used anglegrinder again, this time with cut off wheel. Then I bend the heart a bit again, because it wasn´t flat, it was rather crooked (looking from the side it wasn´t flat).
After this was done, I mounted it in my welding vice and started to weld. I had to hold it in place by hand before the first tack weld, but after that it was a piece of cake :-)
Finally I removed the flux with my welding hammer and used a round and a flat files to shape the weld to fit the rest of the surface, so typical to rebars.
Step 4: Finnish
In Slovakia we have a saying that the old love never rusts, so to make sure that this would be true I first cleaned the heart with toulene and paper towel, then I sprayed it with glossy clear lacquer for nice finnish and nice protection.
It took me no time at all to make this heart, so I think it´s nice last minute gift idea from a maker. You know, what´s a better gift that one you made yourself..?
