That’s pretty damn cool right there if you ask me!

The enclosure I built has worked great for setup and practice but I think I am ready to start designing my permanent CNC enclosure. I think I would prefer a flood coolant system over a mist system. Have any recommendations on that? I'd also like to add spindle control to the Mach3 and a quick tool changer.

My new enclosure is built with flood coolant in mind and I'm still hesitant to get it functional.
Plus, I have my mist system functioning pretty decent now so it's working for the small stuff I do at the moment.

Flood coolant is going to be a mess and so I'm holding off because my shop is attached to my house and I don't want the smell or mess to spread inside.
You avoid that issue being in a trailer but it' still going to make a mess and you will have will be aware of what you are breathing in while you are working.
A mist system is worse in that regard so you should already have some sort of air filter or do you wear a face mask with cannisters?

If I do go that route, I'm going to start off fairly small and have found a few decent kits on Amazon and eBay for under or around $300.

Why not have an exhaust fan pulling the vapours through a filter? With the doors closed on your setup it shouldn't take a very big fan to get a negative pressure inside the enclosure.
 
I have a wetjet 46mm intake setup with the oddball stud spacing. I've previously just elongated the holes on standard gaskets, but it's hard to make it centered and not block the carb throat. I've been getting into cerakoting recently and got a cheap cricut vinyl cutter to make stencils for patterns on guns. So I decided to try cutting some gaskets with it.

Take a picture of the mating surface or scan a gasket then import it into inkscape to scale the photo then assign dimensions to all the holes. Unfortunately the cricut software has errors when trying to use a DXF file, but exporting it as a jpg works fine.

I used Fel Pro 3157 1/32" gasket material, it's a bit challenging for it to cut, but I definitely get much cleaner results than I could by hand. I used the deep cut blade, max cut pressure and 8 passes.

If anyone has a wetjet setup and needs some gaskets let me know. Or you can use this photo and set the length to 3.8".

Well that changes things

I do have a WEN air filtration system installed above the general area so I’m not too worried about airborne particulate, it’s the actual flood coolant I have an issue with.

Having worked on numerous grinding beds with up to 60ft of rail, I have seen the damage that the different chemicals can do to the cabling, track system and electrical. I just don’t want that mess in my garage. Maybe it won't be that bad, I'm just not currently motivated enough I guess.

Been working on fitting some removable seats to my Jetski bus, I can fit the Pro series in perfect with the seats in place, or they can be folded forward or removed for more space.
Was a bit of work making a extra floor panel to make them sit flush but came out well I think .
Cheers, Adz

Always landing on 0 moving the same direction does not indicate 0 backlash, set your steps/inch in mach3 using as close to the full travel of the machine as you can to minimize error. Setting steps/In over .05” and adjusting steps to compensate for backlash is for sure what’s throwing you off, .9mm of tool deflection would be a broken tool unless it’s a 6” long 1/4” end mill. Once you have steps/in close you can set backlash by moving against the lash one direction, and stepping until you just move your indicator the other direction, or by the method you already stated and using difference in commanded and actual position

I was adjusting for backlash by using a dial gauge and using g0 x0.05 and g0 x0 to move that 50 thousands. Every time I move it using both moves, it lands on 0. That is why I think I have the backlash adjusted correctly. I can change the steps per to basically any number and if I make a + and - move I end up back on 0. That is why I don't think the issue is the backlash.

The issue I am having is that the g0 x0.05 move doesn't end up at .050 on the gauge. If I adjust the steps per to make it land on .050 and 0 after every move, it actually makes the Y axis more out of round. Maybe I am doing something wrong and need to try something different, but again that is why I don't think my backlash is the issue.

Currently I am not wearing any mask or using any fluid. I spray a little WD40 on the part sometimes but mostly just blow the chips off the part with plain air.

Yes, pretty sure I understood what you were doing, you cannot move out and back to the same position and expect to measure backlash. The difference between your commanded .05" and what the dial indicator is reading is your backlash but you should properly set steps/in as I suggested first. PM me if you're still having trouble, but doing what I posted should get you much closer than you are. No matter what trying to set steps/in over .05" is a bad idea.

Nothing crazy, but I did make myself a new shop stand for the superjet. My old one was like a foot off the floor and working on it was killing my back. Now it's at a nice level to work on while standing up straight.

l keep 2 stands that are the height of my hitch hauler and then l have a build stand that l use that puts the bottom of the ski about four feet in the air.Otherwise a day of working bent over is a long evening of pain... Nice work on the woody!

On the topic of shop stands, I thought using one of these adjustable work benches from home depot. Only issue is the base height is a bit too high. I don't know if it can be lowered in anyway but it could be a great base for a stand.

I have a design for an adjustable height
ski stand similar to what we used to use for our sleds. I even have the worm gear that allows it to raise and lower with a cordless drill, I just don’t use a stand enough to warrant building it yet.

Basically keep the base and ski bunks and add a scissor mechanism in the middle.
