POTD- PROJECT OF THE DAY: What Did You Make In Your Shop Today?

pontiac428 said:
Today, I continued with the band saw conversion. I don't have much on hand in the way of scrap that was going to be useful here. I had some scrap left over from some other thing long ago that was probably not 6061 (at least not T6) that amounted to some bits of 5mm sheet. So I squared and cut and layed out and drilled and tapped. It wasn't going perfect, but it was working out. I decided to just zap it with spray transfer MIG. It's a fast moving process that is easy once adapted to, but this was a one-shot, one kill with the settings. Worked out fantastically strong, but nicht so gut on the visuals. About what I expected. There was one problem, though. I was fumbling with my setup and getting the corner clamp set, and in the shuffle, I turned the base plate around and welded the wrong end. I'll start over tomorrow after I find another piece of material to use.

can't you just cut it and re-weld it in the correct orientation. I'm pretty sure metal can be cut apart .. squared and welded again and again.. unless there is some alternate universe in Bremerton, WA?

If I didn't do that at least once in every project, I think I would scrap it and start the project over because something was wrong and I missed it.

I didn't want to make a career out of a motor bracket, so laid it out with a compass an punch, and drilled it on the drill press. It worked fine, but I think I'll do it again using the mill. I thought about doing it on the Langmuir, but again, way too much prep work for a simple little mount. I'm out of 5" material that isn't half inch thick or better, so I need to hunt for drops next week at the metal supply to finish this.
 
On the subject of bandsaw speed, my feeling is that the critical one is SST speed. Too fast and you fry the blade.
For AL and wood, too slow just means you take longer.
On my modified bandsaw, I have the DC motor plus worm drive set up where minimum speed is SST. Maximum speed is safe for steel.
I can swap a belt to speed up a notch for faster Aluminum cutting, and use the original motor and pulleys to do wood. I have only swapped to wood twice in the last year! Most of the time I just need a quick cut or two in wood and I accept the 2-3 times longer cutting time. Not a big hit for 30 seconds of cutting VS maybe 2 minutes for a speed swap or 10 minutes to change speed and install the wood blade.

I hear you. I used to be able to shoot from the hip, but I think those brain cells long since expired. If I am not pathetically methodical with everything it usually jumps up and bites me in the trailer.
I used to think that I had outfoxed my misspent youth, but lately I have begun to wonder..............
For the record, I don't need much of a reason to hit the local metal supply store. Sometimes I think they leave stuff out in the open if they know I am coming. Their trash is usually my treasure.
 
And forward it went.

First, I converted the slots from metric to 3/8 :rolleyes:

Plenty of room in the base.

I put together some supertwist belt. It's darn convenient, I'll say that. It will never run like a quality V belt, though. :dunno:

Live test. No issues, even got the direction right.

The servo motor is nice. I held the speed control in my hand while going through the speeds and ran everything for awhile. Just idling with the drive train at 3500, I couldn't even detect a change in temp on the heat sinks of the motor or controller. I think 500 rpm is pretty smooth, 1000 is smoother, and it's peachy all the way up.

I've got to get the control mounted next.
