Re: Unknown lathe

The joke is on me being unable to read the small plate that is there. It is at an angle where I can't read it, plus I have astigmatism and can not read if my glasses are off, ie, turning my head. It does have a red outline that makes a cross on it, but unable to read anything, if any printing is th...

Re: New guy with a new used mill lots of questions.

This Old Tony on YouTube did an excellent video a few years ago about how to properly check a mill vise and it's well worth searching that one out. Edit, it was easier to find the video than I thought it might be,https://www.youtube.com/watch?v=l5m-kA_Oq_4 Staple this to your forehead,:-) NEVER EVE...

Re: Starrett #123 26" Vernier Caliper

Opened the box of my Mitutoyo 8" Digimatic Absolute Vernier which I rarely use yesterday and found the screen has gone dark. Opened the battery compartment and the battery has leaked destroying the internals. Priced a new one, $230, can't justify buying one at that price, back to the old trusty mec...

Re: Buy Acetylene Outfit for Both Acetylene and Propane?

I have a Smiths oxy-acetylene welding set that has the plastic knobs for adjustment on the regulators. They are still original knobs from when I purchased the outfit some 45 years ago but I have it in my home shop and take care to not bang on them. You shouldn't bang on the knobs anyway since they a...

Re: gunsmithing tools

A local gun show might be a good venue if you can determine what the tools are worth. I'd look at a website like gunbroker.com and search out gunsmithing tools to get an idea of what other people think the tools are worth before I'd take them to a gun show. I realize some of the listings have an un...

Re: New Input on Overspeeding Motors with VFD's

Your brace for the loader hydraulics should be strong enough to hold against any down pressure until the hydraulic relief valve bypasses and should have two pins to secure it to the cylinder rod so it cannot fall off or be ejected. I consider that to be the only safe way to keep the loader up when w...

Re: Power two machines with one motor

Male the line shaft as you propose with a quick belt tensioner on each machine. When you finish with one, loosen the belt and perhaps even flip it off the drive pulley. Put the belt back on the next machine and re-tension it.

Re: Drilling Hard Rock With Carbide

I found out my little Kubota can put enough stretch in a 4" tow strap to make the end sail by my head when it comes loose. I think reducing the size of the objects I pull will add to my lifespan. Your little Kubota can put enough stretch in a 4" tow strap to make the end remove your head if it hits...

Re: Chainsaw Sharpening: Files v. Gadgets

Do the files for chainsaw sharping come in different diameters and if so how do you know which to buy? Yes the files do come in different diameters and the box the chain comes in should specify which file to use. As the chain is sharpened the tooth height is lessened and a size smaller file is reco...

Re: Horrors of Buffer Safety

This is similar to what can happen on a buffer, but this time it was a bench grinder. I was cleaning the chain from my chain saw and thought it would be a good idea to clean the chain on the wire wheel. Well it started to remove the grime and without warning, the wire wheel grabbed the chain and wh...

Re: Newbie - Buying first metal lathe

Time for my 2 cents worth (not worth much these days). The OP is new to lathes. This discussion has devolved to ideas that are more suited to experienced users and to being able to make use of the precision and speed of different lathes and work holding. Lets back this up a bit. Starting this user w...

Re: CAD conversation to G-Code

Yes, with some caveats. There are quite a few programs to do this, some with more functionality than others and some which require a specific format of the file to convert. If the part is simple, something like this may suffice.
