Yes, the berg cutter is just like Nicks cutter.
I just used a long 8mm rod, and made a round block with a slot. The block has set screws onto the rod, and it holds the cutter. The 8mm rod goes all the way through. It is the pilot, and also what is chucked on.

I recently finished an all new 2332cc engine with new CB Wedgeport heads. I had it on the dyno breaking in the cam, and more than one pushrod tube seal on each side started puking oil.
I rarely have any issues with push rod tube seals. I sent a quick message to Pat Downs, and he confirmed my suspicion that the seats for the seals are not cut deep enough.
I made up a quick tool, and cut all 8 seal seats on the mill.
Pics are before and after, seal height differences, and the one light grey head is the seal height in an OEM VW head for reference.

| How the heck did you make that cutter? It looks like it was peeled back from the rest of it. Are they cut at a 45? |

It is supposed to be concave- not straight. And seals need to stick up above a little.
That is the beauty of machinetools- you can make more tools! |

sorry, i disagree
I see no advantage to the seals sticking out on one side. And it will just be one side, and that's the problem, shifts it sideways, metal part of the tube hitting the head, won't seal well. |

I checked a bunch of OEM VW heads, and none of them leave the seal sitting high. They are all almost flush. This pic I posted above is an original VW 043 head. If you look at them closely, they are a straight cut. It’s really obvious on the case side.

The main shaft has a 3/8” cross hole. The cutter is just a piece of 3/8” round tool steel I used to make the cutter blade itself. The cutter slides into the main shaft cross hole, and there is a set screw up from the bottom to hold it in place. It all came out of the scrap bin.
I think it was 38deg.

If it seals then that is all that matters. The tubes be at an angle and the seals will crook and one side be sticking up some.
And the pockets be rounded as they were from factory |

How did the engine and heads work besides the oil leak? |

It was leaking bad enough I didn’t even make any pulls. It was dripping all over the fancy polished stainless header, so I made it through the cam break in, and shut it down to fix it
It will be back together here soon, and back on the dyno for tuning.

Last summer on our 16 day, 3200mile Utah bus road trip, one IDF manifold base broke a bolt flange off. I made 2 phone calls, and had a used CB offset in hand. Swapped it on, and drove home.
I had my buddy weld up the old one, and then I needed to make it flat again, and spot face for the nuts.
I 3D printed an angle plate to bolt the manifold to, and went to town. I had to make a sleeve to fit the arbor into the 8mm flange hole, but it all worked out nice. Quick porting on the inside, and the whole thing is all back together, stronger than before.

My dad used to put a worn down abrasive chop saw blade into his Skill saw to cut big sheets up. It was really loud and slow, but it would do it.
These days, just find anyone with a plasma table and have them cut it. The cut edge quality sucks with plasma, but it will still be quicker and easier than trying to do it by hand.
Or there are always mail order shops like Send-Cut-Send, Laser Bros, or OshCut.

Any woodworking tool can cut aluminum, although how long it will survive doing so varies.
Last year I cut up a lot of 1" aluminum scrap with a screw drive framing saw running at 90 volts to slow it down, that's was pretty hardcore LOL, but it works, and made an absolutely profound mess also.
I was going to say I didn't know what a slide saw is......
Then I realized it's probably like a table saw except the work is guided on a trolley. I've seen pictures of such things, but they look expensive.
It's cheap to clip to size with a big sheer, and it's nice to have it cut to size with a water jet.
In many cases having it cut or sheered to size before it's shipped to you is the cheaper way. |

lots of metal cutting blades these days for circular saws and table saws. they'd have zero problems with alum. your big box store sells them.... _________________ ...david - '66 SO-44 #231 |

YEAH! it's true. Dry cut chop saws pretty common now for aluminum.
And the blades could be used on a table saw or whatever.
You will just have to be very mindful of the danger and mess. |
