Ovenpaa hydraulic press barrel remover

#1 Post by Alpha1 »

Ovenpaa on Friday as part of the shutting down and getting rid of the contents of yet another machine shop I found one of these.

Not the same model but its darn close they have left it in place on my instructions. I would like to save it but I'm struggling as to were to have it moved to. If it wasn't so heavy I would take it home. I have got till next Wednesday to move it or its in the scrap skip. The amount of exotic metal I retrieved is staggering.

Get it!

The press was a game changer for us, it makes a massive difference to the time it takes to remove a barrel and I have a load of wooden adapter blocks machined to accept different diameter barrels plus blanks ready to go in the 4 Jaw whenever needed. The wood I normally use is a hardwood door step material however for stubborn jobs I have some Oak cut to size and planed ready for use. I put a 1/8" ply spacer in-between the blocks when I bore the hole for clearance. The aluminium blocks top and bottom have registers machined to ensure things are correctly aligned top to bottom. I use powdered Rosin to give some grip.

Downside is it is bloody heavy and I creaked for a couple of days after lugging it into place. The stand is high, 40" ish from memory and is a grinder platform bolted securely to the concrete floor. I have mine set up opposite the lathe so perfectly located and there is room for assistance when I pull barrels. My preferred method is the action key with a 1/2" Britool breaker bar with a Britool socket and a length of scaffold pole if needed. I also have a universal wrench that covers flat sided actions, MN, SMLE, Mauser and similar (I think I sent you a drawing of it) Again a lump of scaffold pole gets the job done most of the time however I have had to resort to undercutting the shoulder on a few occasions.

Despite being a 25 Ton press I doubt I have ever had to go above 10 tons pressure.

Forgot to ask, what are the exotic metals? I have just received some T5 Titanium for a job and although pricey it is necessary sometimes. All I can say is just get it and keep it safe as it is sure to come in handy one day however beware copper coloured materials as some such as the Copper Beryllium alloys can be very hazardous to your health. At some point it would be worth considering background air scrubbers, they are quite sensibly priced and remove a frighting amount of crap from the air even on a nice day.

When I go into work on Tuesday if it has not all ready been chucked in the scrap skip I will see if I can get it moved and store it it some were for now.
I would like to take it home but it weighs a tonne.
As for the exotic metals I don't even know what most of them are. We had a machinist with us and I just kept asking him do we need to keep this.
For example a piece of round bar approx 2" outside diameter and 24" long his answer to my question was that's worth about £500 it was bought in for a special order. :o

Yes you did indeed send me the drawing as well as several other drawings which I much appreciate.
I am now able to machine using micro cutters.
I have a barrel vice an action wrench and different jaws for them and a Mauser action scope drilling jig based on the one you posted and other bits and pieces that you have sent me. Thank you very much.

I write in marker pen on my material, usually just the diameter if it is a common material such as 6082 or 7075 however I add further details such as 316 or 303 for stainless or T5 T7 etc. For Titanium. I also mark carbon and tool steels accordingly as the last thing I need is to use the wrong material. Racking/storing material is also important, mine is held on some modified trestle stands adjacent to the cutting stations so it is readily available.

The one area I am not so diligent about is wood for stocks, inserts and nose caps, it is usually left on a shelf or even propped in a corner without sight a label which means I can hopefully identify it by eye at a later date.

SAVED its in a container. I have no idea what Im going to do with it. The guys hate me by the way they had to get it off a bench and transport it out side the building then transfer it into a container for safe keeping.
