Mechnanically locked spool valve

Unread postAuthor: jackssmirkingrevenge » Thu Nov 15, 2018 11:42 am

I have more than a couple scrap paintball markers knocking about, I've been thinking of using the trigger from something like that for a relatively large bore HPA pneumatic...

Just another idle though committed to pixels for posterity's sake.

I thank for the scheme, I just experiment with a large caliber. I make a valve with a large flow area

Nice :) needs a lot more flow if you want to shoot something that large diameter at a significant velocity. On the other hand, you're testing indoors, so maybe it's for the best!

How cold is it outside at the moment?

warm, only -5, snow. I understand that the flow section should be more, but this requires large parts, they are expensive, but I can not afford to spend a lot of money on a hobby.
And further. Was everything okay with the site? From 07 to 15 November, I could not create a topic, could not answer, gave an error.

I expected worse :)

Epoxy casting helps as a construction method if you don't want to spend too much money. I wouldn't trust it at low temperatures though!

There were some problems but PCGUY fixed them today after I contacted him, all should be good now!
