Hello, I recently had a large number of 109/156's and MK 5's completely upgraded/serviced (Thanks Robert!) and I was advised the 2nd-stage adjustment knobs would likely need to be adjusted once the seats are broken in. Well, it definitely appears I need to make said adjustments !
I'm starting to assemble my regs (yesterday assembled (1) MK 5 with (2) 109's upgraded to balanced adjustable, hooked it up to a tank, (as I was told I needed to assemble my reg sets and leave them pressurized overnight to complete the 'break-in', and the very moment I pressurized the reg set, the 2nd stages are free flowing. (one 109 free flows unless it's fully cranked down to the max, the other free flows until it's cranked down half way to the max) I was told I'd likely have to do my own orifice adjustments to fine tune everything, and I barely know what this means ?
As directed, I left the 2nd-stages 'cranked down' for a few days to help break in the seats (about 5 days), unpressurized, sitting in the box (they were shipped to me fully cranked down). They were then all fully uncranked down to relieve seat pressure and left in the box. Now I've assembled 1 full reg set, and am assembling set # 2 now. I've got enough 109/156's and MK 5s to assemble at least 5 full sets ( 1 'first' and 2 'seconds'). So I suspect I'll need to have a bunch of 'seconds' adjusted.
I have limited tools (and even more limited reg repair experience). I do have the Vance Harlow Reg repair book, and I've visited Scubatools.com and saw items that might be useful:

I'm debating just letting the dealer handle it, but if it's very easy for someone to make one's own adjustments I prefer to do it myself. (I'm willing to consider making minor adjustments myself, even if I never graduate to doing my own overhauls.)
So, how big a deal is it to do it myself, what good tools will I need, and where are the 'directions' on how to do this ?
Thanks,
Karl
