Fireball releases a giant vise - the Hardtail

Cleaned up the AR400 with a face mill. Shiny as shit now.

Squared up the front of the sliding jaw with a 1in end mill. Was a tight fit between 4th and vise. I would remove the 4th but its squared up for a tight tolerance job.

I got a little lazy while screwing on the nuts. 150 rpm and door overrides. I need to reduce the height on the nuts to solve the vise not closing fully.

Modified
1. Made the fix jaw body back end cap removal for cleaning in a few years without cutting off welds
2. Opened up the tube location. Will seal with a plastic plug
3. Going to install a removable stop on the end of the thread. I would hate to drop the moveable jaw on my foot later on.

Issues.
Thread callout in the drawings is way to long. Not sure why he called out 27 inches but then again I did modify a few things

I need to buy a different nut for the front. Mine were 1.5inches across but needs to be 1.6 If I have a order to place thru Mcmaster or Mscdirect then I'll order the correct one otherwise I will build up the nut with weld then machine using the 4th.

I didnt take a picture but the vise is about 1/2in from closing all the way with the modified jaws. I will probably modify the lock nuts on the all-thread to be jam nut width to solve the issue.


At least this has been a fun side project.
 
Yes, it is:

Now I want to make one in stainless.

I am sending these out for powder coating.

Looks like you got the ACME handle.


ThePanzerFuhrer Did you make any headway on swivel bases? I have two coming, but others may want 'em

BTW, I sent this thread to Fireball Tools on their FB page.

They should see it.

Gonna make some progress this weekend the last 3 weekends were book solid with stupid shit.

@grendal didn’t fuck around with the bases yet. Got the flame cutouts need to make some fixtures to turn them on the lathe. I Want to get the parts out for everyone that wants them first, before I start more projects.

Stopped at the steel house today and seen they bought a brand new 5 axis cnc plasma table. Should be running in a few weeks. They can plasma cut 3” thick :smokin:. Once they get going with it I’ll have them cut some bases out to see how they turn out. The flame cut ones were ok.

Wtf I’m shooting 0 for 2 on shit for you. I got some 1.5” handles here I’ll drop on in the mail

Im still not sure how you knocked everything so far.

Fixed my closing issue. Had to cut a inch off the movable section to account for the removable rear tube. I should be painting the vise this weekend and working on a stupid side project for the pedestal for it. Could be a full fail or something useful for casual usage.

This really has turn into a what the fuck am I thinking project. :lmao: Any guesses why the 14bolt drum is in the mill?

I was hoping to suction the drum down to floor using a vacuum pump. Would provide 2100 lbs of force which would be fine for grinding and minor work. The experiment failed but I have some ideas how to fix it I hope.
 
I have a 24.5x8 steel rim, will seal it up with some 3/8", an 8x8x36 piece of box and a piece of plate for the top. I plan to fill with lead and concrete. It should be heavy enough, will do forking lifting loops.
 
Finally got the vacuum to work after wasting half a day trying to machine the correct groove for a O-ring cord. Fucking thing didnt work out since the cord was too stiff so I decided to pour my own. Used duct tape to give a form to pour the silicone into the groove and about 1/2 above the lip.

Test vacuum on the new setup.

I was able to pull hard without the stand breaking loose when it was pulling 15in HG. Normal vacuum goes from 0 - ~28in of mercury. 15in HG would be about ~1,000 lbs of force holding the stand down.
20220311_153633.jpg



Later on I was able to improve the vacuum to 22in HG with a very small leak once I removed the pump. Still hunting that issue down but need more JBweld to seal everything up. I think the vacuum will work perfect for everything I need to use the vise for. Also started painting the vise red with Rust-oleum Protective Enamel to stop me from fucking around with the vise and start thinking about the swivel mount.
 
Neat idea to keeping it mobile but stable when in use. I'm guessing biggest deal will be keeping the floor clean and smooth enough for good seal and maybe keeping damage to the seal itself to a minimum while moving it around.
 
Yeah, it's making me re-think my base idea, but just to go bigger... so perhaps a concrete filled plastic drum, with steel anchors for my post.

I think it needs to be about 1K to take the abuse we can lay into the thing.
 
Failure on every level today :lmao:. Fucking over achieving mega tube welder guy got me. Must have been the 45acp of the steel tube seam welder :lmao:.

Spent the morning making a sweet ass broach.

Made a press for it and it went right the fuck to disaster. Damn thing galled on the smooth side wall and is stuck, popped the cylinder because I was standing way back and the little pump made too much psi lol.

So will need to make a new broach. Plan 2 for it to pull not push. Will need to put uhmw inserts in the sides to keep it from galling up. Spent most of the day just fucking up :homer:.

peel the tube apart with a death wheel to retrieve

needs waaay more chip clearance, bet you've got a blob of sheared off weld seam jammed in there tight

Not on weld side the smooth sides are the issues with the galling :homer:.

ah I was thinking the side opposite the cutter

you know, jammed against the back wall by the reaction force of trying to push a chip that's begun to act as a cutting edge itself

kinda interesting, that
they used to set up feeds and speeds specifically to build up a horrible galling edge on a cutting tool, back when carbon tool steel was the top of the line.
 
Work is letting us do some lathe and mill training and I convinced them that this was a good project to learn some skills on. Best part is they bought all the materials. Drew up everything and cut it out on the table today. Plan is to do a swivel base like the fire ball guy did. Just with the lathe and not a water jet.

Its a fun project. I finally got mine fully together with the new nut welded on the shaft to fit the handle. Now I need to buy a 41mm socket for when want to power stroke the thing with a drill.

The other guys were not sure about it at first. But they are having fun with it now. I like your vacuum drum idea. I might have to try it out. Was thinking of filling a semi drum full of concrete or something but your idea would keep it lighter for moving around. What went wrong with the o ring groove? Just not enough meat in the drum?

I wasnt able to mount it well in the mill since I had already welded the studs in and a plate covering the center hole. If I have issues with the vacuum in the future then I will mount a flat plate with a machined o-ring groove to the drum or the post.

A better method for the drum
1. Use wheel studs in the holes and use JBweld or epoxy to seal the air leaks in the stud holes
2. Machine a recessed ledge center hole for the drum to glue a cover plate onto the center drum hole. Would need to be on the outside surface of the drum otherwise the glue would need to hole the cover plate in place versus held in place by ledge and seal with glue.
3. Machine a 1/2 O-ring cord in the bottom of the rim. Doing this first will allow for better mounting.
4. Bigger drum = more vacuum force
