Finally finished up one wall of shelving in the welding shop. Lots of neanderthal metal bending, drilling, and riveting. 1/8" diamond plate from some old roll out tool boxes I built for my service truck many years ago, in conjunction with a truck box my renter left behind. Just added a shelf to make it a little more useful. Kind of fun to get this done, as I've been spending most of my time dealing with my well, which has given up the ghost. Cheers, Mike

Something a little different today, trying to break things instead of make things. Wanted to test how strong the lock mechanism is on this new knife design. Tried to test it similar to how BladeHQ did in one of their videos. Only, all I had handy was body weight. Bottom line, I think it is strong enough for heavy knife use and stronger than some other knives on the market today.

The centring scope I got from eBay has been stripped, cleaned - optics too - and then the body was repainted. The body was primed in self etch primer (the body seems to be aluminium or some sort other lightweight castable metal) and then finished in matt black. All of the fasteners have been cleaned and tidied up, and all tapped holes have had an appropriate tap run into them to clean them out.

Reassembiy was the reverse of dismantlement, as they say in every car maintenance manual ever. :)

The above image is of the prism block being reinserted into the body - it has a threaded hole to allow you to adjust it roughly in the body - fine adjustment is done via two set screws and the angled brass block you can see in the other pics riding on the sloped underside of the arbor cap.

Those setscrews are the upper of the ones in the above pic - the lower one and it's twin on the other side adjust the x axis alignment.

These setscrews on the lower part of the scope set the y axis alignment. To set the alignment back to be true after all the cleaning and re-assembly, i took a small spotting drill and did a light peck at some stock I had. I then set the scope in the quill and lowered the head until I had the mark it had made in focus. Then it was just a case of adjusting the screws until I had the cross hairs on the centre of the mark made by the drill.

To verify that this was all OK, I then took the stock out, centre punched it and re positioned the table until I had that aligned under the scope. After removing it, I put in a drill chuck and with a small normal drill, checked if we where on target and bingo - I was. :D

Pretty please with how its turned out. Still don't know what make it is. It's old - maybe 60's or 70's? I suspect it's European, or maybe ex-Soviet as all the fasteners are metric.

Wow Mike!
That tool shelf is fantastic.........and the contents of it show how organized and prepared you are!

Thanks Brino. I brought down the last of the welding stuff from the old shop today. It's nice to finally have everything in one place. Cheers, Mike

I was working on my mill, I was paying more attention to the set up then anything else. I didn't look reached up and flipped the switch into reverse. The end mill broke the second I touched the part, which is when I found out that I found A. I put the mill in reverse and B. that was my only endmill in that size. So I designed and milled up an idiot lock to keep me from doing the same thing again. IMG_2420.jpg

The centering scope project is something I'd like...but too lazy to take it on. The extremely high price of the edgefinders (tasters) depressed me, then I saw a wireless video camera system that would mount on the spindle and show the one point that does not rotate, the true center of rotation. This also was very expensive, in the range of the tasters. Then I saw an eBay ad for a $20 Spy camera, battery operated, WiFi, and shaped just like something that would fit on an arbor. Bought it, made a quick arbor for the mill, and tried it out.

First, the instructions are absurd. I'm ready to go decode Egyptian tombs after getting through these. But got past that.

Secondly, it works, has the depth of focus that is OK, but the frame rate is just too slow to get a good sense of the center of rotation. So another idea down the drain. Apparently a spy doesn't move all that fast.

I needed to bend a 1/4” thin wall aluminum tube to a 1/2” centerline radius. Yes, I could buy a tubing bender with dies, etc, but all this equipment is sitting around waiting for these moments. And I had barely ever used my $240 dividing head, and never the tailstock that came with it. I set them both up on the mill and used the dividing head just to smoothly rotate a bar while I fed a ball end mill into it, made two spools and parted them on the lathe, drilling a 3/8” hole in each.

Then with a scrap of aluminum bar, drilled a 3/8” pivot hole, and 3/4” away, drilled and tapped a 3/8-16 thread. One of the spools slipped over a 3/8” bolt held in a vise, the other spool went over a similar bolt screwed into the bar. The bar rotates around the pivot point, and by holding one end of the tube stationary, you rotate the bar and wrap the tube around the pivot roller while the outrigger roller keeps the tube from collapsing.

Surprisingly, it worked exactly as intended.

Or, I could have bought an $8 bender. I think I made the right decision. :)
