Todays Project - What did you do today?

Wow Mike, I was wondering where you'd got to, you've made up for lost time with that little lot

I had elongated holes in the receiver hitch of a Range Rover I owned, the previous owner had been towing a big horse float. I drilled it out to take a 3/4" tractor pin. Probably less fun than all that tig welding.

Thanks Tom, I really appreciate that. I love TIG welding but I just need more practice.

Thanks, I appreciate the comments.

Got the cart ready to install the tool chest. I'm going to see if I can lift it on with the cherry picker tomorrow.

I was able to get a good start on my mounding adapter for the 3-jaw chuck for my new to me weld positioner last night.

Started by machining some T-nuts for mounting the chuck to the weld positioner's turn table.  The turn table has four elongated slots spaced 90-degrees apart.  I figured I may as well machine some mounting nuts so I could use them for mounting other items if not using the 3-jaw chuck.

Started with a couple pieces of .5" plate by 2" wide.


I snuck up on the dimensions by plunging along the sides to within .005" width and .020" depth.


I then dropped the end mill the final .020" depth and moved in the .005" to my final dimension for a clean up cut, then drilled and tapped some 5/16"-18 holes and removed from the mill vise for deburring.


Next up was to cut some .188" plate to match the size of the turn table.  I cut some plate out roughly on the vertical bandsaw before chucking it up in the lathe to turn it to exact size.  It needed a purge hole in the center anyways so that was a good place to grab it in the chuck.


Parts completed so far.


Tonight I will drill the mounting holes to mount the plate to the chuck/adapter and then drill the four holes in the plate to attach to the turn table.  I will then weld the chuck adapter to the plate and call it done.

Mike,

What model and size is that lathe?

I believe it's a PM1340 if I'm not mistaken.

Think that looks like it a bit more than my needs, shopping for a lathe. Want to keep the input power at line 110 AC.

Greg, might I ask why?

It is a 13x40 size lathe. Precision Mathews PM1340GT to be exact.

Ti is a great Taiwanese made lathe.

If you are looking to purchase a lathe I highly recommend giving Matt a call at Quality Machine Tools, he is great to deal with.

Can I ask why you want to stay with 110 VAC power? I think you are really giving up some options by not wanting to go to at least 220 volt power. Personally in a lathe I would even highly recommend going 3-phase to be honest. The 120-degree overlap of the phases really smoothes out the lathe and is especially nice for low speed threading.
