Bren Gun Carrier Track Straining Bar

[rob love]

I just used one yesterday. I like them better than the cam style.
They were stowed on the early Cdn carriers (first couple thousand only) on the front hull plate. Although they were meant more for the early "spring-and-ratchet" style of front idler adjuster, they work great on the simplified version as well. I suspect it didn't take long to realize that putting exposed springs on the front of a cross country armoured vehicle wasn't a recipe for long term success.
I've made them out of 1" squre bar and never had a problem other than the excessive weight.
