Re: "In the world of spuds today"

That list grows pretty fast the more you think about it doesn't it lol. Maybe we need to wait for JSR to test the precision of his machines before we start talking him into throwing money at trinkets he might need in the future :P Now whe're talking nice clamping tools, at the job we've collected a...

Re: "In the world of spuds today"

That's a nice looking vice right Gippeto! Also has some proper weight to it, which usually is a good sign. How's the upwards travel on the moving jaw when clamping down hard on a workpiece? The one I linked to has the benefit of the vise screw claming downwards, preventing the jaw from tilting when ...

Re: "In the world of spuds today"

Purchasing my own property has definitely opened the flood gates :D While you're here, what style of milling vise would you recommend? Is a tilting swiveling vise actually useful or am I OK with this for now? I've always mostly used the latter for the Sherline and hardly ever used the tilting colum...

Mechanically actuated quick dump valve

To get myself to build some stuff again I decided to slap a cannon together in my lunch break, with all designing and calculating done on the fly. I noticed that the projects where I spend a lot of time designing and preparing often don't actually end up being built at all.. Basically this is a quic...

Re: JSR's workshop chronicles

Looking good! you've come a long way since the epoxy batcave :P
Does the machining equipment perform as expected, and do you have any nice projects planned?

Re: Mechanically actuated quick dump valve

Any chance of internals pics? Will take them when something inside needs fixing, shouldn't take long :P The chamber indeed is stainless steel, it's an old helium tank I rescued from the recycling bin at my employer. You can clearly see the "I grew up on PVC but I'm an adult with access to metals no...

Re: Coaxial Piston Cannon Troubleshooting (no air pressure)

I would try to find something like a PVC end cap or tin can with a reasonably tight fit in the piston housing, and use a piece of reasonably soft rubber as a sealing face. If the piston is too loose in the housing the most simple solution is wrapping electrical tape on the front and back of the pist...
