The holes on the end are for through spindle coolant. I don’t know what the side holes are for. I did some looking online and I haven't found anything. Hive mind suspects Haas is rebranding YG1 shrink fit holders. That's consistent with what I see in their catalog. I don't find a reference to the holes on the outside though. They are threaded..What are the holes around the circumference and on the face of the tool holder projections?






I have watched your thread for years, I'm 100% sure with a 100 hours you could design and build something superior to what is on the market in the 7-10k price range. It is also custom to you and your space and needs. They are relatively simple, I've build quite a few for painting and composites work. Filtration is not rocket science. Pick the right filter, put the right amount of airflow through it, win. That information is readily available on the interweb. You can get fancy with baffles and cyclone for larger particles and filter life if you really want to.Short answer is definitely not. Longer answer:
Guessing $2500 in filters, proper blower, motor controls, steel, paint, etc. It would easily take me more than a week to design, fabricate, paint, assemble. Not to mention the time to get all the parts.
Time is my most limited resource. That’s not to say I’m rolling in dough. If I had the time to design and make a downdraft table of comparable features, performance, and quality compared to what I’m considering buying- I would use that time to run parts that I have in the queue.
Things are different once the shop and tools are how a guy makes a living. I think the downdraft table could easily be a 100 hour project to do it reasonably well.
I have definitely considered making one. Once I started really looking at the three stage filtration systems I’m seeing, I realized I’m better off buying one. There’s more to a proper setup than a fan and filter.
My day to day reality is just adding something to the shop that is ready to go when it gets here is still a challenge when it comes to time.
GREAT suggestion. Thank you! Typing this out made it even easier to make a decision.












I modeled the part and put together the CAM to cut the holes. I programmed it to skip around to help spread the heat being put into the part. It worked well.
I selected each of the 288 squares in the most random way I could. It was nearly painful. The result was the torch ran back and forth. I didn’t see any evidence of excessive heat. I didn’t have time available to test to see if letting Fusion do its optimal path would be okay.I saw the video on your IG of cutting it out and was curious why it was skipping around...makes sense now! Thanks for explaining
Thanks, Matt! I started with the most difficult cover first. The grill area looked intimidating at first. The CAD is getting so much easier these days. I wanted to do everything I could think of to help manage the heat input into the material.When I stated reading the post I thought you’d switch the squares to holes and drill them instead since your setup is equipped. Impressed the remaining material didn’t end up a twisted mess. Nice job! Bet the customer was happy as piss. It having ti wait months to put it into service.






















To be fair, their "sales" have cost me over $20k this year. And, I'm really grateful for their offerings, and price point. Or I wouldn't have near the setup I do. I have a buddy that said the same thing I did when we both got the email the other day.I laughed out loud at this one!

Absolutely! I’ve been eyeballing them for the Acra since I dragged it home two years ago.You’re going to really like those collet chucks.







It does pump out a lot of heat. The old unit was a trivial amount of heat. This thing is putting it out. I'm not sure it's enough capacity to heat this big space 30 x 40 x 13' without any electric heat to help it along. It will take some time to get a feel for what it can really do. I tend to keep it rather warm in the winter. A lot of my work is at the computer.I have been amazed at how much heat the Hyper Heat units can put out in our winter climate. I think you will like them very much.
I’m pretty sure if I added a second unit to this bay it would all but eliminate the need for the electric heat.
My shop has yet to go below 75, but it's nice to be able to have the doors open.
Good luck with the Mitsu. I went with a decent brand (Daikin) and have had no issues for 5 years.
