Thank you. I was given one of these boring bars but I had no clue on how to operate it. I think with your help I will be able to..... I am familiar with bridgeport mills and lathes but a boring bar is new to me.
Still one of the best Boring Bars ever produced ! WE used to square the Block decks 'parallel' to the mainline beforehand to ensure the Boring Bar would 'bore' as close to 90" to the mainline as possible. Just say'in, quite common the Block Decks are NOT parallel to the mainline from factory and quite often are out .007" to .010" or more 'end to end' from the mainline. "Boring" with a Carbide cutter on Cast Iron will result in 'fracturing' of the parent Cast Iron left behind in the Cylinder after cutting.... this 'fracturing' can be .004" to .005" deep.... and hence AERA, SAE, Piston Ring Manu's like Hastings, etc.,.... ALL used to reccommend an absolute 'minimum' of .003" be left for "HONING" to remove as much of that residual fracturing in the Cylinder Walls as possible.
,,,,,,,,Thank you sir....I had a chance of buying a bar like yours,,,,,and did not know the set -up operations,,,,,,,,,I would have been screwed into russia..............Anyway, I worked in an automotive machine shop that had a big boring mill,,,,,the owner named it Godzilla......NO CHATTER......
I have an identical bar. I really enjoyed the video. I'd like to have seen the hook on top for the cherry picker. I don't like to hone more than .002 either.
@@survivingmaineona20acrefar77 ,,,,,,,,,,,,,,what precludes the honing operation for best ring seal,,,is paramount..........I believe a block should be bored in its total stress condition,, meaning ,,, torque plates on the bank or banks and main caps torqued to given spec.........for perfection , ya need the ridgidity of a boring mill...
I have the same boring bar I have used to bore motorcycle cylinders using a boring table. My problem is setting the cutter. I set it up as you showed but never get the bore the size it is set to I even sent out my setting micrometer and had it calibrated? Any suggestions
Keep the tool warm in your pocket even before you set it so it will grow less in the cut. and also make sure you hold pressure on the tool tight on the same side of the mike. I hope this helps
Tim, can you still get the parts for older Van Norman equipment.? I had an in chassis crank throw grinder, never really trusted it, a friend just had to have it.
Most mechanics nowadays will tell ya to get a new block compleat from the factory but this method is how it mostly used to be done
Nice looking job

Thanks, i learned alot. Seems i have got lucky finding your vids. 👍
Neat!! I never have seen this before. Thank You for sharing 🏁
Great video!!!!!!
Good info . Never used one but may get the chance soon.

Honing is the part i am not fond of either.

i don't know for sure,there are after market tool holders but i don't know who makes them
There are some parts still sold by Van Norman, and some aftermarket, but I'd check their site first shop.winonavannorman.com/
@@charlesmayberry2825 Thanks Charlie, kinda looks like they're just a shadow of what they used to be.
After its cut the bore how do you retract with out scratching the new bore? thanks
Retract the cats paws and slide the bar back then lift.
@@survivingmaineona20acrefar77 Thanks for that, if your doing two cuts it wont matter scratching the bore on retract but will it damage the cutter?
@@aaaaaaaaaaaaaa4151 It's carbide and doesn't seem to be bothered by it.
I have a 1988 460 are they worth anything?
I'm sure they are worth more than junk by a good bit
