as an aside , youre not too far off a balnced valve with that long poppet head,, but by and large , balanced valves are a pain in the tush longer term , some might say im crazy , but the fact is they are..
Why you think that? I have some that have seen couple of seasons without any service. And a lot of shots.What tube are you using with that big bore build? Looking good so far. The toilet type valve seals very easily. Should not give you any problems. Marko
nice , u got a way to tighten the front half from the end of the tube ??
cool.. i see a lot of heat in the steel milling for the slot.. few ideas.. one ,lower the rpm by half , especially if its stainless , but really for any steel.. 2 , since its on the lathe , try and have a spray lube bottle in hand , yea.it might get smoke but you will get less chatter, less heat, better finish.. It would be nice if someone invented a valve where there was an external lock for filling , then , once filled it unlocks the poppet ..just thinking outloud. also , for big bores , at least in my opinion , its always easier to start with a larger tube.. but , guys have made tremendous power with little 7/8th tubes so its preference i guess. A guy named chip smith used to make these 1.75 inch , 4500 psi main tubes that were titanium.. I recall he hydroed one to 17500 psi before a bulge occured.anyway , enough babling , it looks good cant wait to see the numbers.
solution there would be smaller end mill , more passes ( the less surface interaction between the cutter and the part, the less rigidity is required ) when slotting , interation is maxed out. everything coming along well , so not much of an issue anyway
