I can spare some Shell Tonna 68 way oil. I buy it by the pail. Send me a pm & we’ll set something up.

Nicely done. Good use of the rotary table and tricky set-up. When I had a need to make new curved T-nuts for a lathe compound, I bolted two oversized pieces of rectangular stock with a spoil shim underneath to a face plate on the lathe, 180* apart. The distance between them was set the same as...

Your thoughts & design are more or less in line with how Dumore builds their TPGs. Their smallest one has an integral spindle with various adapters to hold a variety of mounted points / small grinding wheels. The more components get “added” the more the run-outs stack up, even at very tight...

The height H of a sharp V-thread with a pitch of 0.6mm is 0.51962mm (Machinery’s Handbook, 29th Edition, Table 3, pg 1881. (Sharp thread is one without a peak / root radius and is only theoretical - the dashed outline in Fig 1. below) If you are going to keep your compound at an angle, you...

From your description, you probably need to adjust both the clutches & the brake. Most of the time, the clutches are run too tight. The manual gives specific “spool-up” times for a chuck when the clutches are engaged. Follow that time precisely; do not make them tighter as the clutches will...

If the scale is too long, you can always trim some off.

Both of the above are excellent ideas and are what I would consider the “Rolls Royce” version of a hold down system for grinding stones. Great projects too! Here is what I use: A) three small pieces of paper to support the stone in three spots off the mag chuck (first side only, because it is...

And a few more unique items (some of you have already seen some of the items on display at one of the Calgary meet-ups): 1) A 3J chuck without a scroll - but the jaws still move in unison. This system uses a ring gear & pinions driving precision square threads to move the jaws. 2) Allmatic...

Here is my example of @MrWhoopee ‘s two piece table vice / holdown.

I’m planning on coming up.
