20' long table, 5HP spindle - Port Aransas, USA

The heavy lifting is about done and now it's onto the electronics...here's a picture of our 6' X 20' table. Can't say I'm sorry to be done grinding angle though on the last piece...a redo...we figured out how to quickly grind.

We're going to give a try to the new Geckos, the 251 minis which are about to be released.

Here's the reason we're building a table of this size also...a previous project we will be offshore fishing on this weekend.

Chuck,
That is a really impressive looking table. Let us know what you think of the new gecko drivers when you get them up and running. I am sure others are intersted as well.

That is just insanely large. I'm guessing that the cost wasn't that much more than for a 4'x8' unit - maybe 800-1000$ USD?

Chuck...
Great photo. The only thing missing is some nice logo's (Heck, if Gerald has JR, Marc, Doug and I minding the forum pages we have to do quality checks! )

Exceptional work. I like the channel extensions on the main channels.

Good luck making your power cat's.

Now, I can't wait to see how long it takes you to surface THAT table ?

Congrats,
Sean

You betcha it'll have a Mechmate logo. Not a whole lot more cost in the grand scheme of things going this size but considerably more work involved. Things like run out on the main channels become more critical too. Since our standard sheet size is 20' X 5-6' there really wasn't much choice, we had to go long.

If anyone happens to be down our way in S. Texas, consider this an invite.

That's Little Bit Pearson there, one tough hard nosed inspector. When we were building our cat her favorite place was striding along on the overturned underwing section. Don't try to pass off a pinholed weld with her around!

Chuck,
Have you had a chance to try out the 251s yet? I dont think anyone here has tried one yet.

The mini 251's have yet to be released but Gecko says they'll be in production this week and available next. I am eagerly awaiting and will report results.

I would be nervous of the 251's if you have to pay the postage on returning them for repair/replacement. If you live far from Gecko, and production time on your machine is important, don't volunteer to be a test pilot. All the recently launched Gecko products had some or other issue for the first couple of months for which free replacements were offered - but the postage and production time was not factored into the "free" part.

I agree with Gerald. When Gecko releases a new product, I usually buy a sample and run it on the test bench. For production work, I always use a product that has been on the market for at least six months - preferably longer.

The 251 seem a little light-weight to me when compared to the G203v. I run my PK296B2A-SGxx motors at 3A, which (I believe) is maximum for the 251.

I recognize sage advice when I hear it, and stand well advised. However, in the spirit of experimentation, and assuming they actually get them built and available in the near future, I think I'll go ahead and give the 251's a try. They will end up bundled up and sent back for 203's if the frustration level gets to that point but the appeal of a $37.00 drive is there.

I have the luxury of no production schedule at all so a bit of downtime isn't an issue. According to the long drawn out online collaboration on these drives and their design, 3.5A is permissible. I'll heat sink them real well with conductive paste and see if they puke. Now if they take the motors with em...hmmm...

Chuck, glad to hear you going into this with the right attitude. Essentially you are volunteering to be a "beta" tester for Gecko. The world (that's the rest of us) needs guys like you!

How did the 'testing' go! ...

I've done beta testing of software before for vendors, at times it is a blessing, but there is a reason why it is called the 'bleeding edge' at times!

Hi all,

Well, there were so many delays for the 251 Geckos I ended up just buying a couple new 201's to go with a couple old ones I had on hand. They have worked superbly, no reason yet to wish I'd bought the vampires.

If I was doing it again, though, I'd buy the mini gecko four driver setup with breakout board. Less money, package solution.

Good to hear from you again Chuck!

So, is your table actually in production already?

Hi Gerald,

"Production" is a rather strong term for what we're doing! Yes, we've been up and running for several months. Other than the pinion slippage issue we've had zero glitches other than operator headspace errors. She's a very impressive machine, it's almost comical to see this massive beast twitching around and producing tiny detailed objects.

I've cut some aluminum, we're still in the experimental phase on this. We're hoping to integrate Maxman's lube/coolant suggestions for cutting the softer, gummier grades of alloy with a shop built version of a commercial microdrop (fogbuster style) dispenser. Interestingly enough, our best results so far have been with using an 1/8" two flute upcut spiral, single pass cut on 5mm. Things look very promising, at this point we're researching various small boat designs with the idea of a production run.

Awesome machine. Will send pictures.

Chuck

Chuck,

Great table. Nice job!

As requested by Gerald, I've added your build to the Builder's Log, here.

I made some assumptions about the start and completion dates. Please correct me. I also assumed Port Aransas is in Texas. I'm a fellow Texan and I couldn't find another Port Aransas except for the one in Texas.

All your machine needs now is the logo's. Many of us got them from Joe (jbmclain), if you're interested.

Regards,
John

Hey John,

Thanks for keeping up with this stuff, I'd been thinking I ought to update the Mech progress.

Yep, Port Aransas Tx., outside Corpus Christi is da place. If you're ever down this way drop on by. All the info on the spreadsheet is correct, we're pushing a 5 hp Colombo spindle. Refining the Mechmate has become somewhat of an ongoing process, finally got a dust foot I can live with installed and set up the auto axis zeroing routine using the Mach Blue screenset. In lieu of a pendant we're using a Logitech wireless controller with good success. I suspect we'll look at a homebrew auto toolchanger at some point.

Appreciate the tip about Joe and the Mech stickers. I'll give him a shout and see if we can make this machine official.

Thanks,

Chuck

Chuck,

It just gets better and better! Largest table to date, Columbo spindle, dust foot, Logitech zeroing and possible tool changer. Can't wait to see the additional pictures, nudge, nudge.

Yep, been through Port Aransas...scenic route, Corpus Christi to Galveston. I'd love to see your operation and MechMate.

Regards,
John
