Seems like these videos are 5 years old and nothing recent posted, but if the uploader ever sees this, the appreciation level for these videos is really up there. 💙

You are one of the best teachers I have ever heard/seen, bar none! Thank you for all your work in in producing these videos!

THANK YOU!!! This is gonna save me SO much time on my Patrol ribs!

Good job. I once worked for a company name General Forming. This is known as Hydroforming. We did it on a much larger scale. Rubber under pressure flows like water.

nice system seen the rubber being used before on embossing letters into sheet metal they used letters cut out of metal stuck to a mdf board and pressed into rubber with sheet metal in between , think you could do door cards with bead roll shapes by using the same method though you would need to shift the panel a few times under the press to get the whole surface done , wonder how thick a material you flange with it before it maxes out the 20 ton press and if you can do something similar using an english wheel with a rubber wheel instead of a press i wouldn't be surprised if you could bend over the sides to make a mounting flange of the wingpiece using the same template and method , though you might go over it after pressing it to get it at a right angle but you should be able to make the initial radius bend started , maybe even at the same time as doing the holes you might be able to get most of the potatochip out of the center piece by preloading / adding a small raise in the middle of the mdf template , this strip of wood under the middle at the top should be enough , the mdf will deform some but that should help against the aluminium bowing away from the flanges

surprised the wood form doesn't break under the pressure. Cool stuff, thanks !

Great video, can you build fuselage, propellers, nose etc? please keep posting these kind of videos

cool idea

У вас очень хорошо получается объяснять, вы в какой области специалист. Уважаю людей умеющих работать руками.

Polyurethane sheet McMaster Carr Part # 8789K71 ... choose 60A. Any backer under it is fine, the Polyurethane sheet does all the work. 12" x 12" x 3/4" thick about $115.00 plus shipping. They have different sizes too.

is this metal O condition like your nose rib forming video? Thanks.. Great video!

What type of aluminum and heat treat is this? Thanks for the video

Does the neoprene rubber have a hardness scale and are they both 1” thick?

Could you give more specifics regarding the polyurethane and neoprene rubber that you used (i.e. the part number and approximate price, if you recall)?

I like that dental wet dry grinder lol.

Where did you get the piece of rubber?

how much spring back did you account for in the flanges ... if any ... or do you plan on leaving the inner flange at a 87degree angle approximately after the pressing ... a flange tool would be much better than this press method for single hole flanges ... and is more accurate ...

Have you tried this with a male wooden part to fit the female wooden part? It seems to me that if you made a male 'cone'... then the press would do the job in seconds as it would only be pressing on the actual part required, so the flange would form immediately... No? Plus, I think this might avoid the whole rib being out of shape too... Worth a try? You'd only need the very same router that you used to make the female that you have now.

For this particular exercise, wouldn't it be simpler and faster just to whip a hand flange-making tool around the holes? (It would be different if the press could do all four at once.)

I'm interested in the replacement air driven hydraulic pump. Can you tell me where you purchased it?

Will the pressure break the mold?

can you tell me the material type for rubber

20 ton? are you sure that's big enough. Nice job though.
