- Steve Morris has his new Rottler F69A running, and the guys are getting training on the new machine. As such, they walk you through how the Rottler F69A decks and bores with ease.

Pretty neat, but I'd be interested in how the zeroing operation is done on blocks that don't have a crank/cam centerline. i.e. DOHC inline engines. Or even DOHC V8 engines. How does it determine the block is at 0° with the deck upright? Does it require a special mounting plate or does it just get bolted up and measure off the main cap registers? Or does it guesstimate by probing the deck in multiple areas? I MUST KNOW.
Nice machine, if you know you know:-) Looks like Marty got it set good for you.
Can you show one episode where you check the crankshaft bores, or is that not needed, because you take that as your Zero and from there you bore the cylinders and deck your block?
The crankshaft bores you are talking about are called the “main bores” and they are used to mount the block in this machine. To measure the main bores he would have to take that block out of that Rottler machine. Oh and the zero he is talking about, I think it’s the centerline of the crankshaft.
what alternatives machines are there to the rottler f69a ? are there better machines out there more importante cheaper machines ?
That's a bit of a loaded question. The simple answer is yes, there are numerous other options, but that greatly depends on what you intend to machine or need the machine to be able to do.
Love Rottler machines. Back in the beginning I convinced My dad to buy one of the Bigger portable boring bars. It has advanced a long way since then.
I get this machine I picked up that it figures in to the bore machining process?
The bore concentricity to the top of the block as well cam and crank!
Straighter the bore to c&c centers and 90 deg to each end and the V the less moving friction and HP...
Sleaved engines like heavy duty Diesel’s it is imparitve to get that as close to zero as possible.
I see you are very cognitive of those issues.
Glade to see people out there that get that.
Verifying the main bore for diameters and straightness would only make sense, especially, as it is the reference / datum for everything, and any corrections would / should be done before putting it on the B mandrel.
Personally, I’d like to see Steve’s method as well.
I’m curious if it interpolates the offset of the clearance cut or does it just offset in the X axis into the main web?
Where do you get the specs for where the cylinder location should be when you’re probing to bore the cylinders?
I've never seen an engine machine this was cool.

everything how not to do a video. 1) Camera movement made you seasick, 2) no personal safety equipment during machine operation, 3) not representative of high quality postings from this site. D. Dunn, PE, Owner Dunn Engineering
Why so salty? As someone who is researching machining options, these videos more then satisfy questions I had/have compared to reading just the technical data off their website.
