You should buy a hard coupling nut from McMaster. Then you just have to knock a few corners off and slip it into the tube.Thanks for the comforting words. I think about 18 pages ago you said you built your current one with the1" 8tpi and i thought, good enough for that dude to abuse, good enough for me
The bit im not looking forward to is plug welding the nuts into the bar.
Will do. Should work well on the Bridgeport table for welding up the vise. The squares are nice.I have been eyeballing those. Let me know how you like them.
Sounds like others should have included a "Been eyeballing them also.
" so you could purchase a set.....Wonder if I could shame them into it.Been eyeballing them also.
whats with the jaw faces on the Columbian? Threaded the sides of the jaws for bolt-on faces?I spent close to a grand on squares during their cyber monday sale. 10 out of 10. Would bang again.
Yeah. Brass soft jaw covers and they tapped the side of the original jaws for 1/4"-20 button cap screws to hold them on. I bought it at an online auction, thinking it was going to be a bit bigger. I had vise disappointment when I picked it up.
I bought the hard couplerOne of these:

I left a half inch of the nut alone. It can stick out of the ground I’ve a bit. Gives you a good edge to weld to along with some plug welds.I bought the hard coupler
I also tried tiging 2 nuts together. I am no 'fireball tool' at welding. I managed to get those fuckers to shrink togeter and lock up pretty solid. You fuckers were right.
Without a lathe its a royal PITA to grind down the coupler nut, but im getting close.
Thats exactly how im grinding mine too. i figure ill put the rod into the nut and center the free end of it in the rod before tacking it in place so my imprecise material removal doesn't make the nut uncentered.I left a half inch of the nut alone. It can stick out of the ground I’ve a bit. Gives you a good edge to weld to along with some plug welds.
Thinking about picking up a farm cylinder and making a quick hydro broach. I really hope the dude bending up the tubes at the steel mill didn’t fuck up my batch lol. Gonna have to measure them up tomorrow. Worse case I’ll have to fly cut one possibly 2 sides of the moving jaw. It’s sad because the other sets all fit together perfectly.
Yeah it’s in with the ups tube packageNot sure how but USPS arrived before the UPS delivery.
ThePanzerFuhrer, is the bearing block blank in with the tubes? Might have forgetten to chuck it in with the plates.
Got most of my tools setup yesterday for the project. Mig is off to the side but Im ready to get rolling on this project. Already have the dross knocked off the parts, light sanding with 40 grit orbital before I throw them in some Muriatic acid tomorrow to clean off the mill scale. I need to buy a sandblaster one of these days.
I’m getting sick of moving those boxes around they are heavy. Last ones were 47 pounds a pieceMy mailman hates you.
STUPIDITY AHEAD, READ THIS AND DONT FUCK YOURSELF
Well I was going to be done with this tonight. Then i did something fucking stupid. I had the inner tube (moving Jaw) inside the fixed jaw when I did 8, 1.5" welds (2 per side, top and bottom) for the fixed jaw holders. Needless to say the inner tube is somehow now relatively jammed. I can close it all the way but am really struggling to get it more than 1/3 open, I assume something either arced and i have a little tack causing interference or the tube warped causing a spring/interference fit of the two tubes that is stupid strong. I figured i could just use the bomb ass screw to back the tube out, i ended up cracking the rollers on the trust washer. It was backing the tubes out before failure
Much PB blaster has been put down the tubes since sticking. It helped, but i suspected i had already cracked a roller before
Current plan: get 3 more thrust washers and just keep backing it out sacrificing thrust washers to my stupidity. Then grind on the tubes to return them to slip fit.
So which of you geniuses has the solution to my retardation?
Yup. Was a perfect slip fit, was cruising through the project and would have been done by 9 tonight
Heck,I planed to get primer on it tonight too. Dont get ambitious schedule wise, you always fuck it up somehow Yup. Was a perfect slip fit, was cruising through the project and would have been done by 9 tonight
Yeah, that is probably it. My mig is a 120V baby and so I TIGed it all. Welding the sides to the tube with TIG is a PITA at my skill level. It doesnt help that I dont have 3/16s rod or something equally massive. Feeding fast enough is tough.
It wasnt moving at all until i switched to the snap on 20" ratchet and gave it the beans closing it. That got it moving, but opening it is a cast iron bitch. I should try that tomorrow. I think ill have to get longer bolts for the bearing race if I want to use the main bearing on the inside. Then flip the main cap around backwards and crank it on tight. Give it the beans with the big boy bearing carrying the load while waiting for my new baby bearing to arrive.
Thank you for the good idea
I hope you weren't doing that in your garage and I hope you got that muriatic acid way the fuck away from anything you didn't want rusted. The funds will almost immediately rust anything nearby. Even with the cap on the bottle I wouldn't store it inside.Can you build a slide hammer with a round tube or something else. We have all made that mistake for welding.
My progress tonight was awesome but also a pain in the ass and probably not worth it. I picked up some Muriatic Acid (concrete etcher) tonight from Home Depot to remove the mill scale on the parts. Worked awesome but the setup was shit and neutralizing the acid was a pain when I was done. I used 5 gallon HD bucket with a 1:3 mix and PVC coated gloves to treat the metal. In a second bucket I put water and baking soda to neutralize the acid on the parts. Also sprinkled baking soda on the floor for any drips which did happen. Really nasty stuff to use. I really need a sandblaster.
Top left is after etching and Lower right is before.

Crap did you want 8” jaws?
Yes sir that’s what I have marked down for you. You along with a few others will be up this batch. Got the parts to build a hydraulic broach for those tubes. Also bought a large fly cutter incase I need to shave a little bit off the inside tube.
