I've been lurking on this site for several months and gaining a lot of useful information about CSM. So I thought I should say hi, join the site and contribute especially now that I have something useful in the form of a CSM that I sort of finished last night.
The chain saw shown is my brother-in-law's ancient (1972) McChulloch with a 16" blade. For the moment this is all I have although I might soon be getting access to a Husky with a 24" balde.
Being in too much of rush I didn't wait for the paint to harden so there has been some cosmetic damage during assembly - no big deal, I might give it a bit of a touch up but it'll soon get dinged up anyway.
Because I spend a lot of time at my day job in meetings where I stay focussed by planning my next tool project, it may be a wee bit over-engineered for what it does.
The main differences between this and other mills I have seen around are;
- it can be adjusted to accomodate CS bars from 16 to 24 ". This is done by loosening the lock nuts and turning a horizontal piece of allthread, the mill then expands on the RHS up to a bar length of 24". The reason I have kept it this small is I only have access to small logs. If an when I see a need to tackle big stuff I will either make a whole new mill or make an new RHS for this mill that will allow it to handle say a 24 to 36" bar.
- The outer part of the blade is held at its tip by a single ended clamping arrangement. The way this is done has the effect of tucking the whole bar tip well under the mill and much less bar and chain is exposed hopefully making it safer.
The main handle is horizontal and is permanently welded in place. A second horizontal handle rides on the horizontal allthread and can be locked into any position within in the range of available allthread. The vertical handle is an ally handlebar mount post from the remains of a racing bicycle. The black handle cover material is hot water pipe insulation.
At the moment the allthread adjustments are done with a spanner but I have some small cranks in production.
I anyone would like to close ups details I am happy to provide pictures.
I haven't fired it up yet as I have no logs. Maybe next weekend.
