So with a baseline of the existing chassis it was onto modifying it. First off was to model how other manufacturers did it. I won’t mention who.

The results were that my chassis was stiffer. So making it the same was out. Then I took a look at the originals and had an idea…

One model later and I had some more results. Same tests

Single bump

Double bump

And finally side load

Settings are exactly the same as the initial chassis tests and despite being a very unrealistic set of tests the results are clear that the chassis is stiffer with the modifications.

Results

Pretty clear improvement. Not that an improvement was the goal, it was more to ensure that by changing things I didn’t make it worse.

Onto the angle-grinder…
