Ho train track nailer made by a vet

Custom made . Tired of trying to drive those little nails well here is the tool! ( PRICE IS FOR ONE) I am a disabled vet and i make these at home. I got into model trains as to have something to do as i am not allowed to do anything from all the nerve damage. I got tired of nicking the track or bending the nail. I designed this to set the nail flush with the tie all you have to do is insert nail in the shaft it is magnatized and set the sleeve over the hole and tap the driver to set the nail as shows in pictures works great. I have not damaged any track or bent anymore nails. nothing fancy just a tool to make it easy.Thanks for looking
