Without good detailed drawings, and a few photographs, it would be hard for someone to know how to make this piece. Ideally there should be some sort of positive registration features (on both ends perhaps) that would maintain the concentricity of the system. Just making male or female threads isn't that hard, but making well fitting threads on an adapter with good concentricity is a bit tougher. Having just made a backplate for my lathe chuck from scratch, there's a sequence one needs to follow when machining it to guarantee low runout. Likewise for your adapter. Without having precision measurements of your pieces, and knowing where the precision reference surfaces are, the chances of making a flawless adapter the first time are low. Just my limited hobbyist perspective on machining.So saying it another way, you need to supply good, accurate and detailed drawings - or you need to find someone else that has your same airgun that they can make machinist grade drawings. Just my two cents.
I just ordered some parts to convert my PP800 to .25 cal, but also ordered a 16" long barrel for use with my Stormrider. I would also like to use an Artemis M11 moderator, but it is threaded to M10x1. I can swap the bottom "cone" with my Bandit cone and make the M11 .25 cal moderator into a M10x1 moderator. That works for the Bandit, but not for the Stormrider. Is there someone that can make, for money of course, a 3" adapter from M10x1 to M14x1? This would allow for flawless mounting of the M11 moderator with either platform and then leave my .177/.22 cal OEM moderator alone.
Rob M is emailing with me now and has offered to make the part.
Glad you got someone to step up to the plate for this. It doesn't sound like it is a hard piece to make, if one is familiar with that airgun. I was just trying to point out that the more info one offers, the easier it is for someone to decide if they can make it. If I had drawings, I'm sure I could make such a piece. Hope it all works out for you. Once I was asked if I could make a bracket. I asked for dimensions and stuff, and found my buddy wasn't all that good at measuring things. Eventually, he gave me a bracket, and I was able to copy it for him. Was kind of fun to do, once it was clear what needed to be done. If I had gone by his dimensions and verbal description, there's no way it would have fit. So that was a bit of the background story why I asked about a drawing. Not directly pointed at you, but more shaped by my experience with my buddy.One of the reasons I got into machining was to support some airgun activities. I'm nowhere as talented as many of the contributors here, but occasionally I can make some interesting things. These hobbies of ours lead to interesting pursuits. To support my machining, I needed to learn 3D CAD. To machine, I needed to make some of my own tooling... Seems to be an endless cycle of learning new stuff Keeps the mind sharp, so it is good.
