Thread: 1/10th rule

I originally made this small mill in the beginning of 2007 to run with a 50cc saw and haven't used it much, mainly because I don't get hold of a lot of small stuff but I have some small stuff coming up so I thought I would give it a little upgrade. The mill is designed to handle 16 to 24" bars but with the chain brake getting in the way on the 441 I had to hang the powerhead out a little further which meant I could use this spare 25" bar.

The naked bar means the chain can be changed with the saw staying on the mill. The intention is for that bar to more or less stay on the mill and if I want to use that saw to cut something else I pull off the powerhead and attach a different bar. Eventually I want to get a 24" 050 chain and run 3/8 LP chain on it.



Here you can see I've dumped the original inboard bar clamp for the bolt on bar method. The inboard vertical is the same 3/4" SHS as before but the horizontal is 3/4" solid steel so I can tap an 8mm thread into it to firmly attach the bar.

This would be for be for the bottom half.

The wheel position is fully adjustable vertically (up and down) via the 1/2" stainless steel rods to cope with whereabouts on the log I am milling. This setup would be for the top half of the log.



Here is some detail.


The original mill was a nose clamp for hard nose bars only, but as this is a roller nose bar I used a 1/4" bolt thru the nose bar clamp method.


Here you can see how the inboard part of the bar is held on by an 8 mm bar bolt - it threads right through the 1/4" thick bar/chain spacer and the 3/4" square solid bar behind that.


And just to top things off I made a pair of stubby SS rods as well.
