WTK: 12 Ton Press Attachments?

Okay, so, I fell victim to the Harbor Freight July 4th sale am now the proud steward of a 12 ton shop press. I know the uses are boundless, but I made this purchase with the express intent of using for barreling and locking shoulder installs/removals.

WTF sort of attachment do I use for locking shoulders? Anyone have an photos or links? I would rather not spend a ton on a full set of xyz, but if anyone has any ideas of something that could be used effectively, and attached/detached easily, I'm all ears. Please PM me here, or txt/email me, if you've got my contact already. Thanks all ...

All of your socket sets from 1/4" drive to 3/4" drive are now "attachments".

Otherwise, it is a case-by-case thing you will have to figure out when you get there.

I would hesitate to use the press on locking shoulders. You have no "feel" when cranking on the handle and can very quickly FUBAR a receiver. I drive mine in with a tack hammer and if the LS has a hole in the middle of the lug end, a punch. Otherwise a brass punch.
It's hard to properly support a receiver so pressure on the sides and rails is even and if the receiver is allowed to tilt while pressing, the left side rail can be bent very easily. So unless you intend to build a special jig to support the receiver I'd skip the press for LS. I'm positive others will disagree.

I do use the press for installing barrels. A set of Ratas barrel vice halves in the press works great. No bolts to dick with. Press works great for removing and installing gas blocks, too.

There is a guy who sells a fitting that goes over the 1" ram head and has a hole for a pin. THis way you can press thingies without whatever you are using as ram does not come flying off; it does suck when you are trying to press something and either the piece or what you are using as ram start tilting. Look for AK building tools.

If you can, go to a welding shop and get some of their scrap 1/2-1" steel plate to use as additional press plates. Some you might modify to have cutouts that are useful for you.

The platform the bottle rides on has a lot of freeplay; you can come up with something to fill the gap with frame. Also do tighten down the bolts that put the frame together so it does not move.

A bucket under it might be useful to catch pins and other parts as they are pushed out.

Pins: they are great to removing pins be them FAL locking shoulders or AK/PSL/etc barrel/sight/etc pins. As said before, inserting is more interesting because the only feed back you have is your eyes. Maybe a 1 ton arbor press would work here. The press also works great for barrels that are pressed in. Or to replace bearings in steering housings and driveshafts.

Coins can be used to level pieces out. As hkshooter said, if you cannot properly support a piece, don't do it.

I guess I should have stated the caveat that I do have a pair of wood jigs that I 'milled' with the table saw, for fully supporting either side of the receiver, during locking shoulder install or removal. Said support jigs might need a little work here and there, but I do fully intend to add the material where needed prior to any attempts using with the press.

I am with HK on this....dont think there is a need for a press to install a LS. I use a small hammer, brass punch and my lap. I dont want to press something there without a lot of touch and feel.
For barreling it should be great with a set of ratas tools.

Get this for the locking shoulders. Easy to use.

D I've used offset wood blocks like you mention to keep a receiver flat and had no issues pressing in LSs with mine.

Use a small arbor press, much better tool for the job.

I missed your locking shoulder comment in the OP with my previous reply Art. Tikiman is correct IMHO. You need more "feel" rather than "force" for some jobs, and this would be one.

I use that on most of the rivets, like charging handle knob (metric and inch), rat tail rivet, inch rear sight leaf, etc. Does it have enough reach to get over the shaft of the locking shoulder or are you pressing against the dog leg?

You need a cheater bar on a 2-ton arbor press, so you may want to define "small".



I personally use a press to push them and a hammer to take them out. But I've only done a few dozen without any problems and I know there are people that have done considerable more that use the hammer method. YMMV.

I strongly recommend against using a hydraulic press for locking shoulders. You have zero control over the force required - no way to tell if anything is wrong. I balance the barrel on my left thigh with the receiver on the bench and my left foot on my right knee like a flamingo.

Tap with a hammer and punch so you can feel the pressure. Should take moderate strikes. If you have to bash it, STOP 'cause something is wrong.

12 ton press is great for AK rear trunion rivets, but no - not for the FAL.

WOW! It's almost as if GP has watched ME tap in locking shoulders

I do the same thing ^^^^^. It gives a great "feel" of the amount of force needed to send the locking shoulder home. Again, I repeat as others have, you need to have this "feature" when installing locking shoulders. It really does help indicate if there is a problem, a overly tight or loose locking shoulder hole, etc.

As far as the press goes, do indeed go get more plates. I commonly use 10" long X 1" thick by 3" wide plates, several different diameters of tube that has been lathed/squared on each end, two more 3/4" thick X 5" wide X 10" long plates with different sized "U" cutouts on each side and every size socket you can name with my press. Also, put a large rag or some such under the vise for when delicate or small things are pressed out. This will catch them when they fall free from the press.

I use carpet samples.

Fcuk using a hammer ... just pressed one out, then the correct one in, using a heavy vice. I'm sold.

Hope you had your bolt carrier and charging handle installed when you used vise.

In the past, there have been some who criticized me for using a hammer and punch (never use a hammer directly, as you can break the dogleg), as somehow "unprofessional". Until I post the pictures from the Australian Technical Brochure Supplement 1977 showing - a hammer! "Shoulder locking replacement, fig 39-43. Yes, in Technical Brochure, they use a hydraulic press, but in the supplement, it is a hammer.

After almost 30 years of experience and thousands of rifles, the "feel" of a hammer and punch, lets me know if something is not right, while a press does not. I have 2x 12 ton and a 20ton hydraulic presses and 2 arbor presses. I still use a hammer and punch for a reason. A hydraulic press without a strain gauge gives no indication of how much force is required. With DSA receivers having a pattern of undersize locking shoulder holes, do you really want 12 tons pressure driving a part into the wrong sized hole?

I found with presses that I do more things for others than my own, just the nature of having the tool, now if you want to get info from some one who doesn't want to talk the press gives you More Power to work with, otherwise vise grips, a Propane torch are all you need.

I have a Need for a Ginger root press and I like Ciders, You are smart and will find your own unique uses I am sure. Did you get or have a welder to go with the press? That will be handy if you do. Enjoying some Real Ginger ale, makes me Not so cranky.
