wow ,good job and clean build .

you got very nice accuracy for smooth bore barrel, so it must be the ammo.

can you give me a picture for the ammo because i have no idea how it look like.

nicely built and good stock,however the seam inside the 3/4" pipe make's slower open time specially with that pilot valve. what i suggest is ,put 3/4 coupling then put 3/4" BRASS nipple and drag the barrel to the start of the brass nipple and done. you have smooth bore that you can make a good round...

they have a lot of sizes,but do you have the money for it .

i give it a try , but what will happen in this proses?

i bought an seamless stainless steel tub with OD of 10mm and ID of 8mm, that tube will serve me in my project , rifling it. tried to fit 7.9mm rod(the cutter) in the tube and he fit exactly and not stuck, week after i did the same test but the same rod wont fit ,the tube and the rod was in place tha...

pretty neat gun and amazing wood stock for sure,GREAT JOB.

so its 6mm barrel if i not wrong , and you have plans to use MOAR pressure in that piece ,about 400 psi ?

Remember that you must be careful when grinding the HSS bit. If it starts to discolor, it is too hot. If it gets to about blue, you have drawn the temper and it needs to be rehardened, which cannot really be done at home. thank you for that information :idea: :idea: that the cause when the workpiec...

thanks for the help

i did some test and i found that the HSS is better than the metal file

sharpining both and try scratch a LOCK in the hardened metal

the HSS superpass the metal file

Do you mean a facemill? HSS is made for high speed and higher temperature applications. Better than a file at least. Ideally carbide or PCBN is a much better choice Head cutter for rifling machine ,so there little amount of heat I know that carbide is the better one but because the small cutter and...

as the title say's which is harder and give me more cutting before it start's to wear .

i want to use this for head cutter

if you can do this ,then you can also build hpa pump.

take a look here for that hpa pump ,simple (if you have at least a lathe) and efficient

yes you can , but you will need thousand of strokes to get 100cc up to 1000 psi, thats if the pump had tiny dead space before the check valve ,
that pump did not have it because its used for liquid's !!!

thanks ,sure you have them too

thats wierd !!! where is the vitran members ,can it be that no one see this valve.

good job ,cant wait to see it in action .
what pressure you whant to use ?
