    small hole boring bar

    Thanks for the replies - reaching in 1" is the challenge. Already tried HSS and its quite "chattery".

    small hole boring bar

    Hole goes in the end of the tube (.313 OD x .243 ID x 36" long) need to increase ID to .246" and its important that the hole be parallel to the long axis of the tube too. Tried grinding down a .250" carbide endmill, nasty job, turned into a mess - I hate grinding / breathing that carbide dust -...

    small hole boring bar

    Need to bore ~.246" hole x 1.000" deep into 4130 tube, concentric to the OD so lathe job. Thinking I need a carbide boring bar. Looks like ~$50 and 1~2 weeks from USA maybe $15 from China but I don't think they'll do the depth. Anyone else been down this rabbit hole ?

    Bridgeport Project

    Kinda late to the party here but thought I'd show a couple pictures of a tool I made to get my spindle nose off - maybe it'll help someone next time. Just a little different pin wrench - gotta make it before you take the mill apart (or on your spare mill). Thick enough to get a big pipe wrench...

    When to replace air compressor tank.....

    Just wondering: Do any / all of the industrial / high grade compressor tanks have a liner or epoxy coated interior, or stainless tanks ? I would have thought that some kind of epoxy coating of the interior wouldn't be that expensive to do ?

    When to replace air compressor tank.....

    "With such a huge danger to health compressor tanks would not only be "regulated" they would certainly have "explosives" sticker on them and stern warnings. It probably would be illegal to even have a compressor tank more then 10 years old. There would be stern regulations regarding testing...

    When to replace air compressor tank.....

    I believe there's several youtube videos - mostly tire explosions but I seem to remember seeing a couple of compressor tank explosions - look quite violent. When is the right time to replace, I really have no comment - just because I'm as guilty as anyone of putting off replacement for $ reasons...

    proper heat treatment

    Just curious; I've done a bit of my own "seat of the pants" fire brick / tiger torch heat treating / tempering. Got the stuff hard but a terrible amount of scale. I've thought about buying or building a heat treat oven - I've wondered about purging with Argon - practical ?, prevent scale ?

    On a related 'it's hot' issue

    And all that heat warms the insulation too - and then it radiates down into your living space. I believe that attic insulation is one of the best ROI there is in home upgrades.

    On a related 'it's hot' issue

    Last Summer I insulated / drywalled / heated / power upgraded the 2 car garage at the '75 vintage house we purchased a few months previous. At the same time, I added gable vents to the garage (didn't want to cut into shingles on top). Vents were the biggest I could find: 12" x 18" IIRC. I don't...
