A few months back I had started to tear down an inflation fan that had a brand new 8hp motor but was on a damaged frame that had been fixed way too many times. Below is just one example of how patched up the old frame is.
I decided not to modify the frames design because the fan worked just fine before and I didn't see a point in making a new (untested) design for something as important as an inflation fan. So, I made my measurements and got to bending the front part of the frame.
After I finished bending and welding the front frame I measured, cut and welded the front engine mount into position.
Here is a comparison photo of the old and new frame at this stage of completion. I really like the look of the new frame so far.
Once I was sure it was lined up, I welded it into place. Here are a few comparison photos of the new vs. old.
I managed to shed a few pounds off the new frame so far. I haven't installed the new wheels yet but I will try to get on it tomorrow. All I have left is to fabricate and install a metal shroud, install new wheels and come up with a creative paint design. I think I can have it completed by the weekend as long as nothing important pops up. I'll end this post with the new frame as it sits right now.
