Thanks, will do!

Yeah - it is crazy to think about what they did in the old days with just pencil and paper!

Thanks, and you are definitely right! I learned a ton from doing this one.

Thanks!!

I hadn't thought of doing that; i'm not sure it would help, given where I see the table flex, which is mainly the legs, and the gantry. I can easily push the gantry 5-10 thou, but I haven't quite isolated where the play is at. I think it is more so in the motor/gearing than the 80/20, but I am not quite sure..

My dog holes only go through the 1st layer. I haven't resurfaced the table yet, but it is starting to need it. I'm trying to do all through cuts so they don't cut into the table, and preserving it. I like this approach better, and another "mini" spoilboard on top for when I do need to cut into it. But that doesn't work for big projects (ie: 4x8' sheets), and you just have to do it.

I'm happy to help if you have any questions! CNC Depot has some great new ATC spindles.

Thanks! It's still not an easy decision on what to buy. I still go by a lot of the statements in my first video about the Avid CNC (link at the end). I still think that is a great machine and a good buy. In my use, I don't think I really needed an 8'x4' table; a 4'x4' would have probably been better, and I don't think I needed the high HP spindle I got. I'd maybe look more into the StepCraft series of machines with an ATC, mainly to get more accuracy and precision with a ball screw, but at the expense of not as much power or speed. In general, I don't cut too fast due to bad quality when doing that, so speed may not be as essential as I was initially thinking. I'd also possibly consider Phantom CNC's 4x4 ATC machine, however, shipping is still prohibitively expensive to California. An Avid CNC with a CNC Depot ~4hp ATC spindle is probably still a good option. Link: ua-cam.com/video/VsXiz4nxAGc/v-deo.html

@@CorbinDunn I have watched that video. I guess i am asking for more details for what you suggest i get from avid and other companies when I order an avid 4x8. I plan on building my own Table Base and really want an ATC. Thanks again

@@braunproductions3254 Oh cool - Aside from Avid's basic kit (minus legs, if you make your own base), get the RM 40 kit: www.cncdepot.net/products/newavidkits -- that's mostly it!

Or RM40C, for higher RPM

No problem, I'm glad it was helpful!

Thanks!!

No, it is fixed. For going faster, people usually use a bigger wheel, such as the 36'er in the photo. I could cruise at 18mph, hold 25 mph downhill, and peaked around 28 mph. It was still decent at climbing hills with 150mm cranks and 1st gear,

Hi! Yes, you can ride it backwards; it is still a fixed gear. Riding backwards on a 36 is tricky to begin with though. A brake is not required..but at high speeds you will want one to control your speed - especially down hills. Even on an ungeared unicycle: your legs won't be strong enough if you are going down a steep hill and exceed ~12-15 MPH (I've seen it happen, and it wasn't fun, so a brake is recommended.

Hi! I think you are asking if this hub works as a freewheel, right? My Schlumpf hub does not, but the 2023 versions can be ordered with a freewheel option.

Thanks, i'm glad it could help! I should do an updated video, as I've now moved a few things around and purchased a few more machines that I had to accommodate. I also did build a closet for my dust collector (there's a video on it).

Hi! Sorry for the slow reply; I was gone a while. I am not making wheels anymore.

@@CorbinDunn Thanks for letting me know! All the best for you!!!

Yeah, for sure...I still do it by accident on occasion (like, yesterday, doh!)

Hi Steve, sorry for the slow reply! I was out a bit. I do not have direct experience with Axiom, and at the time they didn't have a 4'x8' machine, so I didn't look too much into it. They do have ball screws all around, which are great for precision, and likely a lot more precise than the Avid CNC or any other using a rack and pinion system. My best suggestion is to make a spread sheet comparing the features that are important to you, and various price points.

Awesome!

For when you are tramming? Can you explain why you think that is important? When spinning the indicator around, it shouldn't make a difference. When tramming in a vice (etc), it definitely should be clamped to the side and not move.

No problem!

Hi Richard, My apologies for the slow reply; I was gone for a bit. Some racks do the "drop in" style, and I have seen them. I had read somewhere about some problem with them...but at this point I kind of forget what it was. Most industrial CNC machines seem to use the slide in version, so I figured it was the best way to do it.

Yeah! It was a great idea..and it really made it possible for me to succeed with this project.

;)

@CorbinDunn on a serious note, I had my atc for a while and never set it up, watching your videos finally motivated me to get on it. Have been watching them over and over and hope you keep new ones coming. Great content and really appreciate all the work you do to help the simple minded like my self! If you're ever in NJ come visit my shop, I got lots of goodies!

@@thewoodologist8176 Cool! I'm glad it helped get you going on it. I'll definitely let you know if I'm ever lose to NJ - you are also welcome to stop by my shop if you are ever near Lake Tahoe, California.

@CorbinDunn appreciate that! Do you have an instagram account one could follow for updates in case I miss a notification on YT?

@@thewoodologist8176 Yeah! I mainly post on instagram.com/corbinstreehouse/ -- it is a bit of everything, Just workshop stuff is over on instagram.com/corbinsworkshop/ Not much has been going on lately in the shop, as I'm putting solar panels on the roof of it.

Cool, glad it could help!

Yeah, the link is in the Description. I'll post it here to. Add it to your Cart and do the checkout (it's all free), and optionally subscribe to my email list.

@@CorbinDunn thank you

Thanks! I'm glad it helped you on some ideas on what to build. Yeah, the Bobcat is handy ;)

Interesting! What do you think the problem is with the adjustable feet? When I measured movement of the table, it was at the top of it, not at the bottom. I was seeing flex in the table itself, but not any physical movement at the feet. The feet could be a pivot point, given their design.

@@CorbinDunn What highlighted this for me was how you measured movement using the dial indicator off the end of the table. I figured if you completely stiffened your structure as you did, you still have a joint below where your threaded adjustment legs thread into the base plate bolted onto the bottom of your legs. No thread comes without some slop and a half inch bolt will flex. You measured .005’, I could see those numbers coming from there during rapid directional changes. It could be reduced by screwing the adjusters up as far as possible while still maintaining a level table then using the jamb nut to remove play in the threads. Or strut or block your table to the floor. One other person I watched used his phone to measure vibration, I imagine he was seeing vibration from his gear driven rack. Just some thoughts. Thanks.

@@billjohnson7834 Thanks Bill! Yeah, I will try to look into it at some time and figure out where the current flex is coming from. These are some good ideas to look into.

Thanks!

Thanks!

Thanks! I have no idea how much time I spent on cutting joinery...it wasn't too long (maybe a few days), as I didn't have that many connect points as a normal timber frame building.

Sure, start with whatever post you are using and just add in the things I mention in the same spots; it shouldn't be too hard. The fusion one from Avid should work as-is and no longer needs any mods.

@@CorbinDunn That's great, thanks very much for that. Cheers

My pleasure!

So, shortly after completing this I did move away, and I haven't check it out in a few years. I'm sure that some of the doors will warp a bit; epoxy is notorious for moving over time. The wood was dry, and I don't think wood movement would be an issue in this case. I think, if i did it again, I would have some internal support structure.

Cool! Yeah, I did a new v2 dust boot design (there's a video about it). Thanks for the info about the link; I will update it! www.corbinsworkshop.com/shop/cnc-dust-shoe-v2-stls-and-fusion-360-parametric-design-for-3d-printing/

It would definitely be worth trying! I think I've seen some inlay people using epoxy (like BroInWood - who does amazing work). It can definitely help when you need more time for the glue up. I think the longer open time might actually cause more swelling as it enters the pores of wood, but this would be an interesting experiment. I found that the swelling wasn't really an issue once I could press the inlays together really dead straight with a press.

No problem!

Thanks!

I probably shimmed it a good 1/8" on one side -- and this is totally due to the middle leg causing the steel to bend at the point I welded it.

Unfortunately, I haven't used Vectric's software before v11, so I am not familiar with how to edit the post processor for v10.x.

Awesome! I need to look into McMaster Carr's brush; I haven't been super happy with most the amazon ones I have been using. So far, I haven't had issues with the spindle's cooling air fan causing any issues.

Hmm..for a geared hub? Contact schlumpf innovations!

I think I have a video somewhere..I made a "pregnant" oven by adding an extension in front.

Thanks!

No problem!

Making them out of wood is a great idea! No chance of hitting metal with a bit. I might have mixed up the words nut and bolt at some point...hopefully my point came through.

Awesome! I hadn't seen the ones PwnCNC makes - they look similar and probably work great! The square washer probably helps avoid the flex issue that I see in the long clamps - that is a great addition! Their pre-made Toe Clamps at $13 are a pretty good deal. I talked with PwnCNC not too long ago about helping with some of their ATC stuff on Mach 4; they are some nice guys.
