It won't work because the tail stock is too narrow .

What will work is a reworked wide style Stihl bar .You need to make spacer bushings to slip over the 3/8" bar studs that will increase the size to 12MM size of the bar slot .Rework the oil hole a tad and enlarge the tightening hole . I have a Windser 36" Stihl mount that fits both that Homelite on my avatar as well as a125 McCulloch .

Having reworked things on the Homelite the standard 105 driver count in .404 will work .If used on the large Mac it will work with a 7 tooth rim but a driver short to work with an 8 tooth .I have no idea what the count would be using 3/8".

I have a 125 coming to stay at my place.  I will be looking for a bar of about 34 inches to do a "little" lumber cutting with.  It sounds like the driver on the 125 is larger than the 805 making the bar larger where the links enter and leave?

You're getting confused or I didn't explain it enough ."Driver " meaning the amount of drive links on the chain not the drive system .

The 10 series saws use 5/16" bar studs ,the large Macs like the 125 use 3/8" studs so the 10 series bar in that respect wouldn't work unless the slot were milled out .Do to the fact the tail of a 10 series bar is not wide enough to both engauge the bar tightening apparatus plus not wide enough to engauge the oiling hole it just won't work .

This same question arose on another forum maybe 2 months ago .To find out for certain I layed a 10 series bar over a Mac 125 style and there's just no way it could work .

I missunderstood.  I got a 34 inch hard nose bar last year that used small rings over the mounting bolts on my 805. I will try that one when the 125 powerhead arrives.  Is a bar from a 1-43 or a 250 the same as a 125 bar?

Yes but one of any size will be hard to find .

I'll dig around and show what I mean on using a Stihl mount bar .Those are plentifull ,the OEM large mount McCullochs' are not

Re reading that post ,from what you said about  the bushings that 34" bar just might work . 34" is an odd size .Generally you measure the usable length to determine size . If it's 34" nose to tail it would be around 30" usable .

The box for the bar has 323960 for a PN.  It's labled 34" hard nose bar.  The bushing were supplied by the seller.
