    I much prefer the feel that the Micron style spring retainer and adjuster brings to the trigger of Iwata HP style brushes. I now have a growing collection of this style of brush, including Richpen, and Olympos brushes, which all use similar parts. Purchasing the needed parts to do complete conversions would start to add up quickly - something like $91 for each brush, if going with Iwata replacement parts. So, I decided to take a stab at making my own parts ;) .

    This is the style set up I prefer, along with a preset handle - This is on one of my Olympos 100-SB brushes.

    This is the break down of the parts that I will need to make a complete conversion.

    About the only thing I don't think I can do here, is engrave the numbers on the collar on the needle stop. I have never used them anyway, so not heart broken about that. I will put some sort of marking on the collars, but have not decided what, yet.

    Here is my pile of parts as of this afternoon ;). Making progress. I have test fit each part, and they all fit perfectly. Next step will be to cut the handle itself...

    I've actually cut 14 of each piece, just in case I "F" them up :eek:, while working on them - I hope to be left with the amount I want/need :thumbsup:

    Do you plan to plate them? Do you plan to plate them yourself or send them elsewhere?

    I've not decided on finish as of yet. If I do plate them, being such a small batch, I will do them here.

    This brings a question to my mind (what doesnt) , do you happen to know the thread size for crown caps off hand?

    There is not a lot of thread to measure there, but I am calling it 4 x .45mm. I'd probably like to run a tap through to confirm, but don't have one... yet.

    Yeah thats gonna be a PITA for what I had in mind. Was thinking of adding holders to my needle stops. But finding even a JIS fine thread M4x.5 is very difficult. Hmm maybe I could substitute some chinese micron aircaps instead.

    about the only threads on the entire brush I would consider standard are the threads for the needle stop knob in the back of the handle, the needle packing set screw, and the air hose connection... the rest seem to be whatever gets the job done in the space available.

    I think I saw somewhere that someone had mounted air cap to paint cup lid as a needle cap holder.

    I tried several times to make a hand tap to cut the internal threads of the handles I will need to cut in order to pull this project off. Unfortunately, I was not successful in obtaining the results I was after. After some contemplation, I changed direction and took a stab at grinding a tool bit to single point thread the handles on the lathe. While I was apprehensive about my ability to pull this off, it worked out just fine in the end. Got the first handle cut from 7075 t6 aluminum. Wonderful material that will anodize quite nicely.

    Coming along nicely! I like the out of focus background of brass parts. The mock-up brush looks great on your new stand. You do nice work.
