Re: New to me Bridgeport clone!

My BP clone was shipped from Taiwan with the whole head / motor angled with the end of the spindle pointing at about the 2 o'clock position and a plywood support on the table that the edge of the motor was resting on and taking the weight. What is important while moving them is to make sure the head...

Re: Show us your milling machine!

Wow that has to be a rare and very lucky find Bob. Given at least some chips in the paint then it must have been sitting out on a floor some where but not being used. My guess is that might have come out a high school shop or maybe a research labs tool room.

Re: titan machinery milling machine defect

I'd also agree with John & Steve. A fast assembly floor fix when the machine couldn't be properly trammed in is my guess as well. Fixing minor design issues and re-machining better parts for various minor reasons is one thing and maybe that might be expected on some of this equipment. No doubt this ...

Re: Shaperight shaper

No real information on that shaper Earl, but if there really is a tapered cross pin in that one then a tip I recently read on the PM forums was to just use a coat of cold gun blueing to make the difference in the two materials stand out. The other more invasive tip was to mix up a salt/vinegar mix a...

Re: holesaw on a lathe

Nice crane, that looks pretty handy! My thought as well. It looks to be more than well thought out and not a design I think I've seen before Liveaboard. Very nicely done. I've never used hole saws as large as that on metal yet, but with the few I have that chip relief hole seems to be a lot more im...

Re: Wacking the Morse taper out of the spindle

I think your concern is more than justified Mauro. I once read on a bearing website some years ago and I wish I could remember which one it was, but with high precision bearings brinneling can apparently get started with as little as 4 ft. lbs of shock loading. No dimensions for bearing size were me...

Re: Dirt Bike Crank Disassembly Tooling?

A shot in the dark since I know very little about this type of crank assembly. But something much like two opposed chuck wedges used to remove drill chucks from there arbors might work well?

Re: Clockwise Anti - Clockwise To Undo Machine Spindle Nuts

For right hand threads the way to remember is lefty loosy, righty tighty. So for right hand threads it's anti clock wise to loosen and clockwise to tighten. Exactly the opposite for left hand threads. To help properly visualize that on parts facing down, then picture a clock face pointing in the sam...

Re: Breathing new life into an old Kurt

That came out really well. Cheaper than probably any off shore 4" and far far better in every way other than when you have to lift it on and off the table.

Re: India Stones

Those surface ground stones are meant to be used on high precision surfaces and never used as a general honing stone.There designed to remove any high points on ground or lapped surfaces and not touch the surrounding metal.They come as a set so rubbing the two together both cleans and helps to maint...
