    Split bearing housing repair

    My post sorta goes to the guy that recently asked if a Chinese lathe was worthwhile. Yeah, hold your nose, take a pill......................they actually can do the job if you take care, and watch what you're doing. You make do with what you gots. And.........mild steel, especially hot roll...

    Split bearing housing repair

    There's no law, written, or unwritten, that prevents you from making the part out of steel..........if you have the time...........and it's worth your while. Let me preface this with the fact that cast iron is hard to weld, and harder to pad weld........... Padding tends to tear up the lathe...

    Vintage Winch HELP w/ any manufacturer info/specs

    I'm not sure you'll ever find any meaningful info on that thing. I'd venture that it really doesn't matter as long as it works. I gotta winch that dates back to The Flinstones. Nice hand operated old timer. It will move a backhoe sideways on the ground with appropriate snatch blocks. I...

    3/4 ton chain Lever hoist

    These hoists/come along's will not work unless there's tension on the chain. You need to use the small hand knob/wheel located outboard of the handle(see silver thing in pic) to take up the slack. The wheel reels in the chain. Once there's tension on the chain, they will ratchet. Same same...

    Chinese lathe good enough for my needs?

    Been running a similar lathe since 2018. It's not very rigid, which forces you to take smaller cuts. These lathes will run ok with CCMT inserts for roughing, and TCMT inserts for finishing. Ideally, they prefer HSS, but a small radius TCMT will do almost as good...........just don't push it...

    Possible types of steel for this bushing plus alternative recommendations

    It's called DOM, and it's mondo pricey in larger diameters. 2" OD x .500 wall can run around $150 for 42" + freight. It saves on the work for boring though. But it's still way too much to spend for something that's off the shelf that's available for less.

    Possible types of steel for this bushing plus alternative recommendations

    I think I'd set the dog on you if you showed up on my doorstep with a chunk of round stock to make those bushings LOL.. Especially knowing what it costs to buy them. More work than it's worth. I gotta deal going. Rebuilding an approximately $1200 assembly(cost of new replacement IIRC)...

    1018 to 4140? Not sticking

    1018 to 4140? Not sticking

    Let's go about this in a different way. Negativity won't get it done. I see what you're making..........the larger round is the pivot point for your lever. Like said..............grind a flat on the curved piece. Enough to let the large round stock to rest flat on the curve. This will give...

    1018 to 4140? Not sticking

    I would think that if you're welding 1018 to 4140, the controlling factor would be the tensile strength of the 1018, which is less than the 4140. Using 70Ksi rod would undermatch the 4140, but what's the point of using a higher Ksi rod in this situation. Besides..........an undermatch can...

    Remove Large gear from shaft - damaged key

    Aw bullshit (big grin) Heating a CAST IRON(possibly semi steel, which is cast iron) hub to remove it. If'n you don't believe it's cast iron......look at the chips when it's being faced. So.........here you have a piece of cast that's been MONDO heated to remove it from a shaft. And it...

    Remove Large gear from shaft - damaged key

    You're not putting excessive heat into the hub/bore...........you're removing the steel shaft. As the shaft is cut, the tension on the gear is reduced because the shaft is being hollowed out. This is a fairly common procedure. To be fair.............it's a welder thing, not a machining guy...

    1018 to 4140? Not sticking

    135amp machine, and a wire machine at that, probably won't cut it. If you have access to a stick welder...........preheat the assembly to around 350-400, and use a lo-hy rod(preferably 7018). Stick will give you better fusion than a small wire welder. Always set your amps for the thicker...

    Remove Large gear from shaft - damaged key

    I agree on cutting the shaft. But here's where I do it a bit different. Cut the shaft so that it's near flush with the face of the gear on both sides. Then simply cut out the center of the shaft. No need for fancy machining. It can be washed out with a torch. Cut center of shaft out, then...

    AXA or BXA for 11" Delta?

    5/8 toolholders are available for AXA toolposts. Look it up(generally listed as 1XL, or something similar). Handy to have if you're looking for used tooling. There's more available 5/8 than 1/2. Most of the so called 1/2 is actually 12MM if you're buying new. The tools are marketed as...

    Rotary table off center?

    I absolutely understand your method. An axis, is an axis, is an axis. Doesn't matter how you find the center of that axis if it works. You could have your rotary table 3" offset from the mill spindle, and indicate the part/table so the part is rotating true to the table axis...

    Starrett goes private

    Unless ya just wanna disagree for disagreement's sake. I gotta dog here that's frightened of an approaching thunderstorm.............don't have time.

    Starrett goes private

    You're not thinking.............and you're not even consistent with your earlier comment. You say people are not getting paid enough............then you turn around and turn a blind eye to those same people by saying that efficiency is the God of all on Earth. Make up your mind. Efficiency...

    So, I can be peaceful when you starve...............no guilt. Have at it.

    Starrett goes private

    Robert Reich suggested that economies that chase lower cost of goods, eventually wind up in an irreversible downward spiral. This goes to your point, which I do NOT disagree with. As the pie gets smaller, we fight for the increasingly smaller slices.
