I loved how clean looking the domes turned out and how perfectly defined the edge of it was when you unbolted the two halves - seems like that would be a great method to create small domes for speaker cone caps. Great Video!

[@lazyh-online4839]

Speaker cone caps need to be so light that you could literally form it by hand, just put a done on one piece of wood, a hole in another, and push them together by hand. Any aluminum heavy enough to need hydroforming would be WAY too heavy for a speaker cone dust cap. Some of them are only just thicker than kitchen aluminum foil, I even made one once for a speaker my kid put their finger through by taking one of those thin aluminum candle holders and just rubbing over it with my fingernail. Anything thicker than what you can do by hand is way too thick for speakers.

[@parrotraiser6541]

Results look very good. Lots of work invested in that. You could use that method to emboss your logo on the caps. Spinning is another way of making circular dish-like objects, propellor spinners, (and even saucepans).

When you cut out the circle on the 1/2" plate on the bandsaw how did you get the bandsaw blade into the middle of the circle? I saw you cut it at the end, did you cut and weld it?

[@Mishn0]

Undoubtedly. Some band saws even have an attached blade welder. It has a clamp to fit the two ends together and an integrated welder.

[@Joebroni1957]

I came to ask the same question

[@IR-nq4qv]

2 holes appox 1'' in diameter were cut into the plate. The band saw blade was cut and then fed through one of the holes and then welded back together. The blade was then mounted on the band saw, when the hole was completed the blade was sacrificed and snipped again. You can cut and weld band saw blades all day. This is what you do when you don't have a CNC at your disposal, the young guy was using his head. Still wishes he was my son....

[@UltimateMaking]

but the blade is tempered steel how can you weld it without braking it after ? I already tried it on a blade and it just snapped near the weld due to the difference in heat treating between the blade steel and the area heated by the weld...

Even an electric POS (as long as it is still functional) You just cut two appropriately shaped profiles, plumb in the pressure washer, weld the edges together and Bob's your uncle. Sometimes the welded edge will "pop" before you have achieved the desired profile so you have to drain the water, re-weld the edge where it separated and have another go. kzbin.info/www/bejne/pqG7g4CKmrdlhLM You couldnt really use grease in that application because the two halves are never separated after forming. Cleaning it out would be a nightmare. Perhaps the oil pump portion of a hydraulic jack could pump oil into such an assembly. Draining and cleaning out oil would be a lot easier than grease.
