Hey Bro does it matter where the 4- 2mm holes are placed on the hand piece top middle bottom? Or have to be exactly where piston hits the engraver collet?
Hi there buddy, Ive been thinking about making one of these springless airgravers and been doing a bit of research...i have a blueprint without measurements and i have two sets with slightly different meassurements, i wanted to ask you if youd be willing to share your blueprint or measurements and diamiters with me?
Thank you for sharing your information! Good videos. Have you ever used TIG welding tungsten electrodes for diy gravers? Here, it is hard to find hss in 4x4mm size and jewellery supplies company price is crazy. I will try to make my own hand-piece too. I found some drawings by searching pinterest. They were posted through Russian language forums.
I'm sure you figured out by now ( I just saw this video today & it's 5 yrs old) that you were prematurely killing your air compressor. Reset your shit off switch on the compressor back to 120psi. This will inside that 3times more compressed air is stored in the holding tank. The last regulator knob that's at the discharge side to your hand piece set. That's what you regulate down to 4 barr or whatever pressure you desire. Your handpiece will run for a very long time on that tank full of air and only turn back on when it's reached your predetermined low setting if you understand what I'm saying. Good luck
For engraving on stainless steel, you need to use Oleic acid. Good luck!!! Для гравировке по нержавеющей стали нужно использовать Олеиновую кислоту. Успехов!!!
@@sphandengraving5691 yes i am on Instagram. I am still engraving yes, but not making videos. My kid takes up all my time now 🫣🤣. Thanks for stopping by.
Nejc, what a beautifully made handpiece, really does look to be a professional job - and the sound it makes is just musical, testament to the quality of the build. Just beautiful - is there any chance you could send a copy of the drawings for making one of these?
I have a few issues with the idea of using A/C compressors as high duty cycle air source for a pneumatic engraver. Such compressors are meant to remain hermetically sealed and use the flow of refrigerant directly over the motor to remove waste heat from within the compressor via the condensing coil of the system. Eliminating the refrigerant from the cycle eliminates the cooling for the motor. Secondly, simply strapping a axial fan onto the compressor shell as you have done will not provide sufficient cooling to keep the motor in good health unless your duty cycle is minimal. While the shell may feel cool when using such a fan to cool the compressor, inside the shell the motor itself can still be overheating and degrading the insulation on the motor windings. The motor itself does not have good heat transfer pathway thru the shell due to large spaces between the motor and the shell. It is also possible that such windings are already partially damaged if a used compressor was operated with contaminated refrigerant in the past.. There is a reason why these end up as scrap... And finally basic physics says that it is not possible that such a fan installed on the shell of the compressor can keep the compressor "colder than room temperature". Room air is the cooling medium... ergo the shell can not be lower than that without additional energy put into the system to extract the waste heat. I'd love to see an update on this
