Slowly getting in shape.

Thanks Alanstone
Glue for PLA is Dichloromethane.

So yeah redesigned red part and printed in pla. Some parts will be glued together..because of some warping issues i sliced the piece.

Very good!
Cool project and strait forward solutions..thanks for sharing this stuff.

peace

Hi

I got the aluminium tubes and printed the first parts.
Changed the meter in size (6mm diameter to 13mm dia.), also got new orings 7.8mmx2.4mm (insted of 2mmx2mm)

Today some orings arrived. Still waiting for the al-pipe.

The orings are 66mmx5mm and 2x2mm in dimension.

Thanks for you reply:) Nice design. And yes i hope it to :mrgreen: So i just ordered some aluminium pipe 3"x8" (80mmx2mmx200mm). Orings are the next on my list but i have some trouble to decide the dimensions and materials...some help is very welcome. Should i skip the orings and go with a flap-chec...

Hi, i am a rookie with cad, but it will be enough to understand the whole concept. Hopefully your will leave a comment or critique The design comes up with only a few parts. 1. The blue one is the moving part. Built of butane reservoir, outer part of the meter and a piston (with one-way-oring). 2. T...

yes the o-ring can blow off.
there are ways to prevent.
use thick string diameter o-rings
use rubber washer instead of o-rings
cutting slots in the way tech did it on his qdv

sorry but i now know all about tungsten and so on but no help for my answer.
need a proper sealing face maybe ptfe? any special design ideas for the valve?
jean

no benefit over a spark gap. but it is for a musket style rifle and it woukd be really cool... maybe it could work with toy gun caps? target is to ignite 5-10x hybrid. and in case of flobert the pressure in the hybrid chamber will rise very high.<-power incrase?
jean

hi
on a muzzel loader the gas of the percussion cap reach the blackpowdwer for ignition.. right?
what is if the gas was forced via a check valve, into a hybrid chamber. do you think it will work? what is a possible material for the seal of the check valve?

jean

ok sorry for double post. here is the concept. i belive you understanding it. because of the 1 1/4 pump tube i think i cant go higher than 5x. jean

edit forgot to say the o-ring near the check valve is floating and works like a pump head.

hi jack i like to go for 20mm/1m for decent power. i know the 100psi rule but i am scare because it is just next to my head... tomorrow i am back at home and show the concept. its based on the .54 pistol i made but just hybrid. the copper t is rated to ~380psi for gas/water. the joints will be solde...
