That is pure cleverness. The modest grease pump for forming small pieces...Grease is interesting, being thick it is somewhat self-sealing, self dampening, does not run everywhere when you open the "hydroformer form" and is not lost. No one spill. The pump is always well lubricated, no problems of oxidation or gripping, is cheap and can be found in any tool store. I'm in awe. Many thanks for the excellent video, that give me an idea for forming copper jewels.

Nice job. The grease-gun is also a useful tool for freeing a seized engine. Don't remove the cylinder head. Remove the rockers from the offending chamber so that the valves stay shut. Break the insulator out of an old spark-plug and weld in a grease nipple where the insulator was. Fill the chamber with oil to the top, screw in the new plug, fit the grease-gun and start pumping! this will give you the equivalent of a 30-ton press that should shift any stuck piston.

The 321 Stainless steel workpiece has holes drilled the same size as the through bolts. At 6:25 Clarence shows the 321 holes have deformed. If these holes were larger, the workpiece could more easily be drawn into the center because the through bolts would not contact the workpiece. This means you could form substantially deeper draws.

This is cool but 2 things I would like to note. SAFETY - I do not agree with standing right next to this as it is pressurized/hydro-formed. If it did pop you could get a high pressure jet of grease hitting your face/eyes. Place some kind of partition between you and the hydro form item and peek over it at the dial indicator and also wear a full face shield as is used for grinding. 2nd point, get a porta-power type hydraulic pump, these are super cheap on ebay, plumb that in and you can easily pump it until the hydro-forming is done using hydraulic fluid. You could also use a air over hydraulic pump and just hit a lever to actuate it, but that would work faster and thus be MORE dangerous. This gives me ideas on how to form aluminum dish, this could then be cut up and the dish section quarters be used as corners on box structures where 2 radius corners meet such as the corners on a box trailer. If I wanted to build a enclosed trailer and wanted the corners to look professional I could build a large version of this, hydro-form the required size aluminum dish then cut it in sections and weld or rivet it to the trailer box corner and it would, after some careful work, look great. ~

Manual grease guns can achieve pressures up to 10,000 pounds per square inch (psi), while plug-valve sealant guns can reach 15,000 psi. ( 1:44 )
@turningpoint6643
4 жыл бұрын
Actually 10k psi is well in excess of what standard grease guns are capable of. At the last mine I worked at one of the heavy duty mechanics got curious and rigged up a pressure gauge and tested a manual grease gun against our industrial level pneumatic greasers. Surprisingly the manual gun averaged about 2200 psi against the air powered guns at 1800 psi on 120 psi of air pressure. Anything higher than that 2200 psi and the lever assembly parts started failing on even good quality grease guns. There may well be specialized ultra high pressure power greasers around that will do that 10,000 psi but I wouldn't know about those. But it's impossible for the off the shelf lever operated guns to reach those numbers. Average hydraulic pressures for any large earth moving equipment I've operated is roughly 5,000 psi and they use way thicker wall thickness for both the steel and triple braid flexible lines than grease guns do.

What isn't shown in this video is that in 1977 when Clarence left university, he traveled home on his beloved Harley. Unfortunately, he crashed and broke the front light cluster. Being a student Clarence couldn't afford to buy spares to repair his motorcycle so he set himself the task of repairing it himself on a typical student budget of $0. He began by making a fire using some of the furniture in his room and melting down his cutlery and a couple of old bedsteads. This didn't provide enough raw material for the tools and parts he would need, so he fashioned the molten metal into a pick-axe from a crude mold constructed from the clay soil in the garden outside his apartment. Several decades later, after travelling on foot across the Americas in search of abandoned mines, Clarence finally had enough raw metal, Iron and Aluminium, to fashion a smithy (anvil, forge, hammers and all), the specialist forming tools and the front light cluster. Now we're caught up with what actually happened.

Reply to: S Morris And... we mustn't neglect to mention Clarence's brief crossing of paths with Forest Gump, who's "smily-face" t-shirt inspired the concept of semi-circular hydroformation techniques utilized with a positive attitude. Sadly, Forest's true love, Jenny, was impressed with Clarence's Harley; prompting her to steal away with Clarence under the cover of darkness (which was made possible by means of the shiny new headlight and SS reflector). And now, we know a few more details of the reflector history.

I’ve seen rubber mats pressed against a mold this and even two pieces welded together with a pressure washer filling them up to make what looked like a very uncomfortable pillow. This so far is my favorite. I wish I had my own molds or ability to make them and the skill and other tools required. I’ve got the ideas, just not the physical ability knowledge or money lol.

And on the grease gun side, if I remove the zerk coupler thing on the end of the grease output tube there's 28tpi 9.3mm diameter threading on which to attach a fitting to couple to the 1/8" NPT nipple you mention...I don't find much with this tpi and diameter. ...maybe this kind of thing is also a solution? locknlube.com/products/locknlube-grease-coupler
