For a first weld, that doesn't look bad at all! Nice!did my very first weld at the weekend EVER! Was super excitingUnfortunately, now I want a welder
Anyway, making some new vise jaws for my HF 4x6 bandsaw. The current ones have pi$$ed me off since I got it and I have a 2x2 stick of QCTP holders I can't cut as the jaws don't extend close enough to the blade to hold the work.
So cut up a nice piece of 3/8" thick angle iron I found at the side of the road (I think), then milled some slots, drilled some holes etc etc. Finally I used my friend's MIG welder and flux core wire (he doesn't have gas for MIG) to weld some braces to the back of the angle iron for some stiffening. Huge amounts of fun. I might need to help him make a welding table as the plastic picnic table he uses started melting towards the end of the job.
I picked one of the nicer welds for a picture

here's what they look like compared to the original moving jaw

haven't finished them yet (having some issues with tram on the mill) but had to put them back on the bandsaw to cut some material for a cargo rack tongue extension. Here you can also see a "not quite QR yet" jack screw to prevent the moving jaw from wracking when holding short stuff. I love my bandsaw - made a coffee AND had a crap while it cut this piece.

also split the nut to take a whole load of slop out of the moving jaw

and made a T-nut for the fixed jaw as the original set up was a nut and bolt, with the nut underneath the saw. Figured I might as well fix that annoyance while I was at it

now I have to record some lectures so I can get back to my rack project..
There is nothing bad in wanting a welder, try mig welding with shielding gas, it is a whole new game. See if you can find a good deal now because of the virus prices are dropping.did my very first weld at the weekend EVER! Was super excitingUnfortunately, now I want a welder
There’s smoke due to the cutting oil... is it a big cut? 2mm doc by 20mm, 40mm dia 5 flute carbide cutter, 750ish rpm and hand cranked as fast as I feel isn’t pushing it. (78 thou, .75 inch, 1.5inch respectively).That's a serious cut. I always worry when my tools make that much smoke. Maybe I shouldn't?
it’s not just a bad pot. Well, the pot was bad... look at the wire wound segment. Completely buggered.Of course, now that I’m about 3/4s of the way through milling the toolpost, the speed control on my mill has decided to give up the ghost. I think it’s just a bad potentiometer (I hope it’s just the pot) but I can’t get a replacement till next week. Boo.
Look up opennrgdotcom on youtube. He makes a rip gate/fence, circle cutter for plasma cutter. Really cool stuff. I bought it and love it. I guess if you just wanted some ideas to make your own..there is that too.A couple things done yesterday and today. I had bought a cheap EBAY roller guide for the plasma cutter but had a makeshift sleeve to fit it to the torch. This is a much better one and easy to remove for using the diy circle cutter guide. The torch simply drops into a ball bearing so you don't have to twist you hand as you cut around the circle. Made 8, 13 and 18" rods to accommodate most circles.
While I had plastic rod chucked in the lathe I also made a holder for a endo scope that fits in the holder for the USB microscope.
More details please. Sorry if I seem dense, but I'd like to understand what you're doing.At work I needed a way to dress these diamond wheels. Need to do it very evenly and change overall profile as little as possible. Pretty much needs to be help dead on center. Came up with this, attach to drill and stone it. Work awesome and saves me about $500 sending them out.
Thank you.Sorry @extropic , I didn't suspect there would be interest in the details. That small wheel that I am dressing is a brass wheel that has a very fine diamond grit that is through out it. It actually leaves a gloss like surface on very hard plastics. i.e. polycarbonate and a material like poly, but is harder and less sensitives to chemicals. The brass/diamond wheel fits perfectly on the step on the arbor I made, it fits very solid,no play and dead on center. You wouldn't want any run out as the issue is, the plastics I run on it clogs up the wheel, at about 1200 runs, it needs dressing. Normally I send them to the manufacturer and it's not free, and the wheels are about $450 a pop, so I only have about 12. When shipping them back and forth
(they are not fast, and NOW, it's a problem as they are an Italian company. MEI if interested.) so many are tied up in shipping. I mount them in a drill chuck horizontally and running at full speed, run them for about 35-45 seconds (sometimes more) until they are evenly clean. (a lot of water and moderate pressure with a low abrasive stone.) I'll make a video at some point....but pretty boring, maybe I put and "after" picture of the wheel.
Please tell me that is not a gash cut in the lathe bed with an angle grinder.Today i had small project to do on my lathe so i took couple of pictures to share it. The project was to enlarge the centre hole of couple of 16" car rims. The first task was to modify the hub i'm using to hold the rims, i cut the centre of the hub and made a relief for the cutter then mounted the rim and made couple of cuts to bring it to size. Quick project and as big in diameter as my lathe can handle, not bad for a small machine as my.

That is really nice! I like the knurling too.I made some spinning tops for my nephews at Christmas time and decided to build another for myself today. I made the outer ring from brass and the center from 6061 aluminum. Bearing is 4mm press fit. Maiden spin was just over 12 minutes.
I found out it's pretty hard to get a good photo of shiny things.
Yeah someone took an angle grinder and cut the bed to make room for bigger things to turn, i would never do that to a machine. You can see in this thread when i bought this machine the old machinist was using it to turn engormast flanges.Please tell me that is not a gash cut in the lathe bed with an angle grinder.
