Some Pics in the Buff

I mean some pics of buffs, and arbors and adapters...

A left hand taper adapter for a straight shaft grinder/buffer. Bought it from Rio Grande. It attaches to the straight shaft with the two setscrews.

Buffs with pin holes are used and they screw on.

A deburring/unitized/beartex wheel held on a grinder. The large washer transmits the rotational force to the wheel.

The hole in the wheel is larger than the shaft and reduced by the bushing.

I made the bushing myself on the lathe, but they are a common part that often come with grinding wheels when you order them.

Saturday Thrift and Yard Sale fun...

I drove around with the kids and Joe (Felice's dad) today and hit a few yard sales, Goodwill and the Habitat for Humanity building materials surplus store...We didn't get much, but I think I did alright.

I thought it was just one of those grabbers for picking up stuff you can't reach. Turns out it's a Gentle Giant snake tong...$1.00 for a $79.00 tool! I may clean it up and put it on Ebay if I ever have the time. Or take up snake wrangling.

I bought three tools at the Habitat store. An old Thorsen 3/8" ratchet for 50 cents (just needed a squirt of oil to loosen the mechanism), A Mightyvac vacuum pump (works) for $3.50 and an old, small, Indestro torque wrench for $1.00.

I bought it just on principle...

Baking Soda and Vinegar Fun

The kids were getting a bit restless this afternoon so I arranged for a quick and simple chemistry lesson...baking soda and vinegar.

Baking soda in the glove, vinegar in the bottle, shake and reaction!

A little dish soap added to the mix and you get a foamy fountain...

In a wide mouth container it's almost more compelling.

Henry and Max had fun...and I kept a boredom related meltdown from happening....

Oh, and a few links I kept meaning to post:

This is the ultimate Hotwheels track, they had some set up at DaVinci days.

A great memoir of wartime in the Dutch East Indies.

Simple Book Repair.

CNC Milling a torso.

Shop Vac Flange for the Sand Blast Cabinet

Chris needed a flange that would allow him to mount a shop vac hose on his Horrible Freight sand blast cabinet. Without a vacuum sand was getting everywhere, to the point that a pair of contact lenses were ruined. Not wishing to have actual eye surgery, he came over and we whipped up an adapter flange.

Chris wisely controlled the camera. Here I am drilling a 1" hole in a block of UHMW. Notice my ponytail is tucked into my shirt.

The block is a 3" x 3" piece sawn from a chunk I had laying around.

Boring out the hole to be a push fit on the vacuum hose.

The camera batteries died midway through, so you don't get to experience the excitement of turning down to produce the flange. Here it is flipped in the chuck to face the other side flat, once we got new batteries in the camera

All done! Chris is going to counterbore for some screw holes, then screw and silicone seal it to the blast cabinet.
He's also sealed every seam on the cabinet with silicone as well. That thing leaked like a sieve.
