No they are not designed as a take down, with a curved butt cap you kind of need a pommel nut to put it all together.

Steel 52100 / 15N20 stretched crushed W's , Stripped Ebony, Maple Burl and Ironwood handles

52100 / 15N20 stretched crushed W's,by maker, stainless fittings and a Lignum Vitae handle.

They have (2) 1/8 pins in them. I only ever soldered one set of bolsters and it was a disaster.

Steel 52100 / 15N20 stretched crushed W's with stainless fittings and G10 handle.

Dyed Maple burl

Just finished this 1080 / 15N20 eyed crushed W's with stainless fittings.

The bolsters are curved with a 2 inch radius. I think that is what you are seeing.

1080 / 15N20 crushed W's ,one eyed and the other stretched with Maple handles and and stainless fittings.

Just got this finished 52100 / 420SS San Mai with stainless fittings and a Walrus handle. a

52100/15N20 stretched crushed W's with curved stainless fittings and Iron Wood handle I have made a lot of knives with Iron Wood and never seen a piece like this.

I find that all my thermocouple eventually get "EATEN UP" inside the forge. I coat the exposed part of the thermocouple with the the refractory that I line my forge with Vesuvius Super 3000, this makes them last considerably longer.

Here are a couple more San Mai hunter i just finished. 52100/420SS , G10 and Turkish Walnut handles.

52100 / 420 SS with G10 handles and dovetailed stainless fittings

1095 / 420SS San Mai , SS fittings with a stabilized Tamarind handle

Forged from 52100 / 15N20 stretched crushed W's. Maple handles one is stabilized spalted and the other is a stabilized maple burl with some fantastic natural color.

Just finished this 1095 / 420 SS San Mai ,with Iron Wood handle and stainless fittings.

Just got this little guy finished for a fellow that want to wear it with his Kilt. 52100/15N20 steel ,crushed W's pattern Dyed Masur Birch with stainless fittings.

I did a little work on the weekend rolling out some 420 SS pins and some 52100 to make up some San Mai billets. I love taking pictures of HOT STEEL.

Those diagrams are using the flow divider to preform a regeneration circuit. This one is wrong and will not work. The oil will take the path of least resistance and simple go back to tank instead of back into the flow divider. No matter how you do it you can ONLY have regeneration in one direction (rod moving out of the cylinder). You can never regenerate the rod back into the cylinder. Regeneration in a circuit is accomplished with special valving and not a flow divider for a number of reasons.

A 4" one that would generate ~16 tons @2500psi and 1.6in/sec @650psi and .4in/sec @2500 psi for the press (think Coal Iron Works 16ton press) and a 1" one generating ~1 ton @2500psi and 6in/sec and 1/4 ton (500lbs) @650psi and 26in/sec. I did a quick check and these velocities are correct but at 26 in/sec the forces required to accelerate and decelerate a mass moving that fast would be huge. I do not understand without looking at a schematic how a divider combiner would be used and you state that velocity id 49 in/ sec. With pneumatics you can exhaust the air through the use use of quick exhaust valves to atmosphere but with hydraulics you have to get the oil back to the reservoir through valving and filters. A small cylinder is not going to take the forces and shock loading with the velocities that you are describing in this application. Your HP calculations are theoretical. Allowing an additional 15% for efficiencies HP required would be a bit more. 1.37 GPM @2500 Psi HP=P x Q /1714/.85= 1.37x2500/1714/.85= 2.35HP 5.27 GPM @650PSI =5.27 x 650/1714/.85 = 2.35 HP

I have designed hydraulic system for over 40 years and believe me this isn't going to work with the parameter you have laid out here. That is why hammers are either mechanical or pneumatically operated.

A friend of mine acquired this knife and apparently it appeared on the cover of a knife magazine from the 70's. The knife has a makers mark J.M.M. and it was engraved by Shaw Leibowitz . I can find info on the engravers but was wanting to see who the maker was and if it actually did appear on the cover of a 70's knife magazine. Any help would be much appreciated.
