No tool touched a VTR in the making of this post.. But the machine modified is used on VTR parts..

Finally had some time to work on the Pneumatic Gib lock for the X axis of my Smithy LTD1220.

The cylinder is mounted in a custom bracket I built tonight.. The bracket is held to the table with 2 M5 screws, I drilled and tapped for.. The ease with which the cast steel drills and turns to dust/oil mess is a bit scary. Found the same thing when I drilled holes for my work lights on the mil head.

I also drilled a hole and used a hardened pin through the bracket and table.. to assist in locating the bracket, and taking the brunt of any lateral shift .. bracket to table… this should allow the fasteners to Just provide clamp load, with the pin locating the two pieces securely.


Over all, it seems to be working…..

The directional air flow valve

got ordered today, now that I have proofed the remainder of the design. Did not want to spend the cash on the valve until I had a semi working system.

Bought a self coil air line 1/4x3/16,,, will cut it up into 3 sections.... then use the compression fittings I ordered today to connect the air source to valve, and valve to cylinder.

Time to clean up and call it a day…..

I have no idea what that is, lol. But I appreciate machining and your skills. (And your shop.)

Did the cylinder come with the longer threaded mount?

No I made that.

Was going to make just an adapter that threaded on to the cylinder rod (5/16x18 tpi) to couple with some metric rod ends I had on hand...... but the rodends are a very high end lined and sealed designed, and the ball in the socketis very tight... great for some application, but not this one. Would haveplaced too much side load on the screw.



So I turned that adapter / link. Milleda slot for the lever, then drilled the hole for the pin.

... made another change to that threaded adapter for a better fit.


The bracket is freshly painted..... just waiting on it to dry.
