I built a tramming tool out of some simple 1 inch aluminum angle and a couple dial indicators to work through the last of the geometry issues on the mill. The indicators were set at a fixed distance which seem to always fall either on the table surface or in the slot but never on both. I decided to fix this problem by building a better device. I like the Pro Tram devices but again the problem is they are fixed either at 5 inches or 3 inches. I wanted to be able to adjust to any distance. Mine will go from 2.5 inches out to 7 inches center to center on the dial indicators.





This is the best work to come off the mill so far. Chamfers are finally consistent around the part. Holes come out in the correct spots and round features are almost round to within .001. I have some vibration that is creating ripples in the surface finish on side cuts but this is probably about as good as I'll bother making this machine as the plans are already being drawn up for a new shop behind that house that will include a new machine purchase. Something a little larger and all linear rail is the goal.

Nice work,

What Cad program are you using?

[Kenny Duval]

I'm doing everything in Fusion 360.

[Paul-JB]

Great work Kenny
I used Inventor many years ago. Is fusion 360 a new version of Inventor?

[Kenny Duval]

I'm not sure of the lineage of the Fusion product. I just started using Fusion 360 due to it's extremely economical access to hobbyist. Previously the only exposure to I had to Cad was a 2006 version of Solidworks.

Still learning....still occasionally having problems. Still a lot of fun when you get it right. Tonight's project was my first attempt at using saw jaws on the new double vise. It actually went well and is another tool to add to the skillset.

I had a couple machine stalls in the first couple of attempts that came down to a gib screw that had backed off and let the gib jam.

Soft Jaws and a good first op part.

Attachment 375980

And a successful second OP.

Attachment 375982

A couple threaded holes and a couple slots to do tomorrow and these will be finished.

[Kenny Duval]

Closer...

Need to grab the correct washers and some nyloc nuts but it's on the bike.

Nice reservoir mount!

[Kenny Duval]

Probably overkill but it gets it out of the tail section. Paving the way for a monocoque piece to be made.

[atomarc]

Kenny,

Very cool, nice work. Must be neat to draw something and have the machine make it. I'll be there soon, I hope!

You guys have been steadily making parts. Just not on the Grizz yet.

I am having a blast learning this stuff. Keeps me from sitting my butt on the couch.

[CL_MotoTech]

I was never much a fan of remote reservoirs, but they do offer nice packaging benefits. What kind of monocoque tail? Aluminum stressed panel or composite?

It will be composite. Prototype will be basic fiberglass and then once we sort of know what we are doing the final unit will be Carbon fiber.

Sounds like fun, albeit dusty, project. I've been looking into print heads for my G0704 so I can print molds for various composite projects I have. Unfortunately the G0704, as you know, doesn't have the space for large parts so they'd have be sectional. Similarly, this is for a motorcycle project of my own.

Dont waste your time and machine adapting a 3D printer head to it.
I did this years ago. It does work but printers are too cheap and easy to acquire.

Yeah, I've been torn about it for a while, but here's the way I see it. I have an open A-axis already (though that's changing soon, but I'll probably expand my BOB/drivers) and decent print heads can be had for around $100 these days. To buy a 3d printer that has the same work envelope as the g0704 is going to be a good bit more expensive than the price of the print head. Considering that there is only a few projects initially that I have for printing I think a print head would pay itself off before a dedicated printer. For example, I purchased a small laser cutter, I used it to reproduce a specific wiper seal (for a vintage motorcycle damper) that is not available to buy, I now have 70 or more wiper seals sitting on a shelf and the laser cutter is used as a desk for my keyboard, mouse, and measuring tools at the G0704 controller. I feel a dedicated 3d printer would end up with the same fate. Of course, the bigger issue is that I am fairly space limited in my 500 square foot garage, adding more junk is almost certainly not desirable, and the wife would divorce me if I put it in the house.

All of that said, I'm willing to hear your side of the story.

It will definitely work and being that most here are here to create, I say do it. As a part time printer it will be fine. Your arguments were the same as mine. I had the 4 axis controller and an A2ZCNC mill, etc. It was fun just futile. Kind of like converting a manual Chinese machine into a CNC machine ;-)

Ha, Kenny, fancy I run into you here

Nice work! Will follow this closely!

Cheers,

Beano...the world is small. Sim Racing and now CNC. The man with the giant servo motor.

I ran my first part today that included some 3d profiling. Turned out ok. Not mold quality by any means but the machine did what it was supposed to do. Can't wait to get the new house built so I can have space for a better piece of hardware. The little BF20 does ok but I just want more accuracy already.

[Kenny Duval]

She's still making parts and I'm still learning something new every time I do something different. Some one needed some pedal faces for a new set of sim racing pedals he is building.
