Fabricated a blade guard for my 26 inch Crescent Bandsaw

It's made of sheet metal and riveted together with AN-470 aircraft rivets. The red has to go though,
probably will end up in black. The top part was made from some scraps free for the taking from
a local heating and air conditioning place. The bottom came from the junk yard and was a piece
of furnace ducting in it's previous life.

Mounted my 4 inch chuck into my 12 inch 4 jaw. Works like a charm. I made some double shoulder bolts out of 1/2 inch stock. The 12 inch will only close down to about 5/8 inch, so this is my solution for running small parts on an 18 inch lathe.

Radius sanding guide for my disc sander....

1/4-28 holes every 1/2" gives me 1" to 4 1/2" radius
Just need to fit a key to the underside...

How do you use it?

 

[Sharky]

Drill 1/4" pilot hole in stock to be shaped, run 1/4-28 thru the hole into the appropriate guide hole and rotate stock on sanding disc.



Go part way around for radius on bars or all the way for a circle.

Yeah Brian. Great flooring job. I see you can run a vacuum as well!!

I needed to use my Harbor Freight shop press today and was annoyed for the 1000th time by being required to use the handle to release the pressure. I took a page out of xalky's book and made one similar to his. I didn't bother to locate the pin and drill a hole. I just made a slot where the original pin is and tapped the adapter handle over the existing valve stem. Like his, materials out of the scrap box. The stem is 1/2" hot rolled with a 23/64 hole in it that is a light press / tap fit over the existing valve stem. Much easier to use the press now.

Wow! Nice job... I could really have used that here in New Jersey this winter!

I got a new hand wheel for the longitudinal feed on my lathe. The original had been broken by PO. Had to turn both ID and OD. Most complicated set up yet for the lathe. Had to use T-nuts and hold downs to hold the wheel in the 4 jaw.

Sorry about the picture. I guess the iphone doesn't have a very fast shutter speed, as I was only running 40 rpm.

"Emergency/Field Expedient" 8mm reamer ...

A timing belt pulley I'd ordered from McMaster-Carr arrived while I was out on the town today. The bore diameter of the aluminum hub was 5/16" and I needed to machine it to fit an 8mm (.315") shaft. Didn't have an 8mm bit or reamer, and it was way too late to go shopping, so I roamed the shop looking for alternatives. An "O" bit is close to 8mm, but test boring a piece of scrap aluminum rod gave a pretty sloppy fit on the shaft. Probably time to go for a boring bar.

But then I noticed that the #115 "High Speed Cutter" in my Dremel set looked about right.

Calipers said it was right around .315" diameter, so I set it up in the lathe's tailstock chuck and gave the part a spin. WOW! The pulley is now a very nice sliding fit on the shaft, with no discernable wobble or slop.

Cautionary note - Dremel doesn't specify the diameters of their tools, so there's no guarantee that the one you buy will be right on 8mm like mine is ... but it's worth a shot, for very little money.
