Congratulations on sticking with your 37 Chief project! It look like you are doing a very high quality restoration! I have been into these old bikes since I was 18 in 1979, and I did a 39 Sport Scout. I too am very partial to the 1930's Indians, they are more streamlined and elegant than the 1940s.
Here is pic from 1980 of my Sport Scout. I no longer have it.
I do have a 1953 Chief, CS61082, under way. It is a very expensive undertaking, but I am doing all my own work, where possible. I have loved Indians for over 30 years, and never get tired of them!
The bike has been in boxes the last few years, so to get motivated and not loose site of the goal,
I mocked up the chassis. There will be lots of chassis tuning, suspension sorting and wheel/frame alignment checks to come.
Again, great job! It takes a lot of passion to stick with a restoration.
