      I appreciate the information and the help I have a j Port Bridgeport milling machine that was my father's at this time I've been looking for a Van Norman boring bar which is almost impossible to find but anyways I have the boring heads and things and the carbide tips I was just curious what was the RPM on the drive going down into the cylinder I believe I understood you to say the slower the better thanks anyways now I know I can do it I will practice with a bad cylinder that I have that has to have cylinder liners put into it just as I start out then I will do all of the cylinders that I have lined up now which is over 22 cylinders for old triumphs and bsa's

      Hey, no sweat, I have ruined my share of cylinders, they were all mine and worn out. But practice is all I needed, now I bore several a year and have no problems if you follow procedures. The biggest of which is not to get distracted. You will be boring like a champ soon. Hang in there.

    Great to watch Dale, I'm hoping that I can do similar with my mill in the future, once I've arranged a powered down feed or knee feed.

      Thanks Dean, yes the power feed is important for that proceedure. Is there a way to retrofit your machine for that. I had a china made machine prior to the bridgeport and it didnt have a way to do it. That was one of the reasons to seek out an old worn out bridgeport. Im very happy with this machine but I wish it was not so worn, you just have to deal with it.

    Good video, thanks. If you could, next time, show how the Allen wrench adjusted the bore diameter. Also, include the prior part where you check for vertical runout of the cylinder wall after clamping.

    • @montana2strokeracer
      @montana2strokeracer  Před měsícem

      Hey Tom, I have done a bunch of these boring videos, I am sure I have shown the boring head adjustment, you just loosen the lock set screw, and adjust how many thousands to remove, and relock the set screw. I don't check anything after clamping, you check the cylinder at 6 places three to front and back, and 3 parallel to the pin, if it exceeds criteria for that machine, then you bore, I normally stop boring when the piston can be put in the cylinder upside down and goes in to the bottom of the piston pin, that leaves me .003 to .004 to hone to fit the piston at which time I also check for taper. This is two stroke, 4 stroke a bit different. You have to measure the top of the piston and the bottom of the piston. Most 2 strokes are 10 to 12 thousands different top to bottom. Four strokes are less.

    For those that have never centered with a dial indicator, when you’re adjusting don’t move the table so that it reads as zero on the other side.
    You will just chase your tail swapping the distance that you are out side to side.
    You want to try and move HALF the distance that you are out.
    If you’re .010” off zero side for side, move .005” then zero the dial again and check side for side until it’s good.
    Another note, run the dial indicator at the top and bottom of the cylinder, it’ll save your butt.

      @@montana2strokeracer Still waiting on both. I got a 8x16 Lathe and the Mill is a Micro-Mark Mini LMill (DC Brushless, belt driven). Probably not the best stuff, but for what I'd do, probably work fine and I didn't want to spend too much, the Mill was $2k with auto-feed table and accessories, and couldn't find anything close by anywhere near that price. Dunno if I could fit a head on it, but I'll definitely try (got some old ones) when it gets here. And I have a TON to learn about both. So looking forward to more lathe and mill stuff from you. I hadn't ever considered either until I watched you.

    Just came across this video fron You Tube recommendations.
    I've bored hundreds of cylinders in the past, depending on tip radius of tool, 0.004" / revolution would be about right to get a good finish particularly if your honing to finished size.
    When set up is within 0.005" I would have done a 0.003" cut if I wasn't used to machine and a 0.004" if I knew exactly how it was cutting.
    Sunnen makes some neat guided stones for honing two strokes that bridge the ports
    I worked in a Suzuki/Yamaha dealership in the 80's and also taught 'Machine Shop' at MMI Orlando (2002-2007)
    You should try a Harley 883 to 1200 conversion, 0.496" to come out (about a pound of cast iron from each cylinder 😁)

    • @montana2strokeracer
      @montana2strokeracer  Před rokem

      Hi thanks for your comments, I have never worked on a Harley, except for some of the Italian two strokes, but I can just imagine the amount of metal that comes from a conversion like that.
      I really like the stones I am using on this machine; I have tried and still have some of the ones with the aluminum scrapers, they work ok, but the scrapers tend to wear at a different rate than the stones. I prefer to hone without scrapers, many times on a portable hone I will use the scraper type, but I really prefer the bench mounted hone for these small two strokes. Sounds like you have a lot of experience with these machines, and I sure appreciate you sharing your knowledge, we are never too old to learn, and I sure have a lot of learning to do yet. Thanks again for hanging out in the shop with me.

    • @montana2strokeracer
      @montana2strokeracer  Před rokem +2

      Hi there, that is an issue I run in to often also. What I do is let the quill run to bottom of travel then slowly bring the knee up to finish the bore. I always thought if there was a line were I changed it would hone out ok. Well I have never had a line. I usually leave .004 to .005 to hone anyway, so it wouldn't be an issue anyway. Yes for me its 250cc and up that I have that issue with. Just go slow and easy, it takes more time but that is the only option I know of...short of buying a boring bar. Good luck, let me know how you make out. Thanks for hanging out in the shop with me.

    I find that my mill doesn't have enough quill depth to clear the whole cylinder on the cylinders I've tried. I guess I could use the knee, but that sounds kinda tricky.

    • @montana2strokeracer
      @montana2strokeracer  Před 6 měsíci

      Hey Joe, mine is the same. I only have 5 inches of quill travel. It works fine for the smaller engines, up to about 175cc's. When I get into 250's and up I use this procedure.
      I do automatic feed to the max depth.
      shut of machine
      then I lift the quill let's say 1/2 inch
      then I lift the knee 1/2 inch
      then I proceed with the automatic feed
      Sure, sometimes you may get a little line at the resume point, but I always leave about .005 to hone. This will remove the line, if there is one.
      works for me. Give it a try and let me know how you make out.
