Mid April:
Finally got myself to the garage again after a few weeks off due to becoming a dad once again April 7th.
Tied some fine stainless steel mesh around the perforated tubes.
Then started filling it with bike muffler glasswool.
Needed some bickering before I got all the fibers on the inside of the muffler.
Then fully welded the first muffler.
