@@DomManInT1 And here you are. And yes line boring uses a bar, cutter and arbor while the work is moved along the bar/spindle axis. A F69 works in the tenthou range typically and the axis lock probably tightens it a little more. As an actual cnc machinist I am not a fan of the rottler UI as its too dumbed down and won't let you see whats going on.
@@Eluderatnight Line boring also used bushings/bearings to "line" the boring bar and cutting too with the work. Thus the name "line" boring. On a rigid set up, line boring can be accurate for location to the millionths of an inch. But, why be more accurate when you can get by with sloppier work? LOL (4 year old comment and still pissing people off.)
@@DomManInT1 I must be really old; we called it ‘align boring’ (or ‘align honing’, c.f. Sunnen method); as in, ‘aligning the main bore(s)’. Must have been shortened phonetically over the years. As long as the mains are within 0.0002 from front to rear, I don’t care what you call it. Cheers
How many thousandths of an inch did you take off them main caps?, and what was the purpose?, can you put in a crank with what are those called again, bigger journals?...
I use the Rottler F69A to stir my coffee at work
Look at the head design of the mill ridged eh? Very nice
Can it do the same in the cam tunnel
Not truly line boring, but I guess with the CNC control they can hold a close enough tolerance that it does not matter much.
My guess is the program locks the y axis.
@@Eluderatnight Ok. What is really cool is when you actually know what line boring is. And can read the dates on comments.

no oil pan bolt holes
Bo, the pan rail holes are 1 of the last items to machine.
I like that machine
Couldnt do a Boxer engine.
Need a bar to be totally in line.
Modern CNC is accurate to tenths.
Your all wrong! This is done to get the girl!
I don't like that!
