Re: CNC tolerances

The bed on my 3D printer isn't flat. I could do a "mesh bed leveling" and map out that curvature so the printer would "know" what that curvature was to some degree but instead I threw a bunch of money ($20) at it by installing a glass bed. Note that the first thing to do after installing the glass b...

Re: Parting tool holder

How about something like this, a self-contained cutoff toolholder. The height will have to be changed if you need to extend or shorten the stickout to accomodate deeper cuts or for more rigidity.

Re: AlphaTIG 200x

All those knobs give you way more control of how the welder works. If you need that control you will want all of them. If you don't need all of them, find out the few you do and leave the rest alone.

Set up voicemail and don't bother to answer the phone when you are working. If they want to talk to you, call them back when it is convenient for you, If they won't leave a voicemail maybe they really didn't have anything important like many of the robocalls don't, Your phone should have a record of...

Re: Parting made easy

In conventional parting if the parting tool digs in it tends to tip the toolpost toward the piece being cut, making the tool dig in more. By moving the parting tool to the rear and upside down, when the parting tool tries to dig into the workpiece the toolpost tends to tip away from the workpiece re...

Re: VFD setup

If you have a smartphone or tablet, take a picture of the motor plate. It's easy to flip the picture so you can then read it. You can even magnify the picture to make it easier to read.

Re: Wood Shaper Cabinet = Welding Table?

I think it would be nearly impossible to fit my tractor and plow up on that cabinet to do repairs. My cultivator might be hard to get through the door to get there and when the grain drill breaks at the far end of the field I don't think moving that cabinet to it will help. Otherwise I like the idea...

Re: Anyone know where I can find this roller?

Could you replace the roller with a skateboard bearing? It might need the mount redesigned but that doesn't seem that difficult. Skateboard bearings are really cheap and the outer race hard enough that it would take a long time to wear out one. I see packages of 10 for under $10 on Ebay.

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.

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...
