Beautiful build @shotgunner - destined for enshrinement in our hall of fame page. If I may weigh in on the water delivery issue with a few random thoughts. I could be wrong but I think you'll eventually want to valve each wheel - if nothing else than to reduce the Niagra Falls of water mist generated by so many wet wheels at the same time. Secondly - and this might only apply to me personally - but the "art" of water management is a huge part of my cabbing experience. Maybe I was spoiled (ruined?) by having independent valves at each wheel but a HUGE part of my development was learning the water requirements of each grit. The lower grits I run with very low water (practically dry) as needed - higher grits like 14 or 50 k need to be taking a shower or they will burn scar the surface of a cab in a heartbeat and you're back to square-one. Regarding drying the wheels - needed or not I always spin the machine for at least five minutes after shutting off all valves. I had a lot of early problems with Nova wheels delaminating so I just developed a habit of drying them out I guess. Might not do anything but it makes me feel better Nice machine jeannie is a lucky girl

higher grits like 14 or 50 k need to be taking a shower or they will burn scar the surface of a cab in a heartbeat and you're back to square-one. Burn scar- I have seen that before and didn't know what it was. I can vouch for it's existence, though. Some stones (I remember bloodstone and obsid specifically), get a dull spot form polishing to much in one spot- where the wheel got a little dry. I had to start the soft wheels all over again. I have never heard anyone mention this before.

...... and so it begins ..... The kids are gonna get sick of seeing you standing there. LOL! And, all kidding aside, but you might want to improve your posture at the wheels a bit, maybe sit or raise your grinder. You look like you are gonna run into some bad neck pain/issues.

Some stones (I remember bloodstone and obsid specifically), get a dull spot form polishing to much in one spot- where the wheel got a little dry. I had to start the soft wheels all over again. I have never heard anyone mention this before. Yuup. You can feel it happen in your hands - the wheel will start to grab the stone because a spot got too hot. If you're not quick enough getting the stone away it can create a scar ranging from a dull spot to white burns that will require a return to a low grit. For me, 140-280 grit get very little water, 600-1200 get a little more along with extra caution not to burn it. 3000 and higher and I've got my rubber ducky out and I'm taking a bath. Good job @shotgunner! and congratulations jeannie

Burn scar? Never experienced it, but I've overheated a few stones to the breaking point on the polishing pad. I tend to use a lot of water on all my diamond wheels, especially during stock removal with the lower grits. Looks like a really great machine but I agree that Jeannie's going to have some neck/back issues unless she finds a way to sit at the machine or adjust its height.
Congratulations to you both on a project well done! I'm sure you'll get it all fine-tuned soon.

Always working on softer stuff here mostly. Never have had any problems with stones burning. I use the most water with low grits and less with the finer grits, but always at least enough to keep the wheel free of any sign of buildup and keep things cool. With yours being basically a clone of my hubby's design, it also sits at about the same height. I usually sit and do cabs. I also find the 5 gallon jugs to be a bit of a tight squeeze as far as hand room goes, and I basically do all my cabbing with no dop stick. Other than that your cabber should be awesome especially for what it cost.
Are you able to use a stick?

I toasted a piece of Hart Mt Jasper on a 600 SiC belt once when I was in a hurry to finish cabs for a community competitive case. That stuff is a porcelain that is harder than the hobs of hell. Burnt it so deep that it was unrepairable.
