Re: Porta-Tool Mainliner
i'm stil experimenting, but it depends also from the bearing, some like more, some like less. i believe that it is 0.02 to 0.05mm

Re: Porta-Tool Mainliner
Hi Ton!
I like 0.002" crush... at most 0.0025". Any more than that and it is a bit tight for my taste. I use mainly KS bearings (German) and based all my TruLInes (same ones you got from me) on those bearings.
The crank will feel like it is rolling on ballbearings when the case is fully torqued at 0.002" crush.
The TruLine is king. The absolute best I have seen. I have bought a mainliner in the past...one! Used it and it did not give the finish and cut I was looking for. Did not have the heart to sell it to another soul -THREW IT IN THE DAMN TRASH!
How are you finding the tools?
best,
nick

Hey Nick
I set them up for VW specs. So, 66.00 to 66.03mm for the second cut...
First second and third cuts all setup within the 3 hundredths of 1mm.
Took me quite a while, especially since it was the first time I have ever worked in imperial. But I worked methodically and wrote everything down.
I clocked up 1st, second and third cuts on 3 cases and and have cut another 3 cases to the size required.
Crank turns smoothly and the tool itself is super easy to use once you have spent the time to clock it up properly.

Re: Porta-Tool Mainliner
I don't have those pics of your tools anymore. Maybe you can post up some and let Peppe see them. I have shipped some stuff to Peppe before. He is a lineboring king also. 
I refurbished a TruLIne bought here in the USA and sent to me by someone, and when it wall all set, the person wanted me to ship it to Australia. There is guy name Clyde there w/ a VW shop also using that.
I try to find parts for the TruLIne but they are not easy to get anymore. So hang on to your tools, gentlemen.
Peace.

Re: Porta-Tool Mainliner
Oh come on, Peppe. No difference if hobby or professional machining..if precision measurement is the topic. YOu use the same equipment, right?
If you bring a milling machine home and use it, same reading and tools are used by the home user. Only difference is the home user does not produce that many products. But same work is involved...setup, cutting, tools, dials.
here is my direct email: [email protected]
I was wondering why you were not responding to my emails. Have sent out messages to you but nothing.
as far as your mainliner toolbits, I can get the bits. The mainliner can be improved on the cutter body size convert to the 'clamp-on' style. The 'setscrew' style cutter body does not hold any tolerance -it is not rigid enough to make the precision cut. It moves during the cut that is why you will see grooves in the bores. If the body is wider/larger and clamp on style -the whole body secures itself on the bar w/ better hold and won't move. This will give you the most accurate cut. I cannot say enough about the bar being only 1-inch diameter so there is some flexing on its entire length. The TruLine does not have that problem as it is 1 1/2-inch diameter!
email me directly so we can get you going on your project.
Just FYI, me and Peppe go way back. I have sent him parts to ITALY from years before -probably at the time the height of online scammers. LOL!
I have sent stuff to Thailand, Taiwan, Spain, Australia, UK, So. Africa, and of course you Peppe.
