Hi Jim

I'm still doing kits. I'll be away however until mid february for some training in alabama. I've got the stock set to 0 for most items on the site to prevent orders until I return. The...

It's looking great Edmond. Good work!

Skippy - It's a US Tool model 114 pneumatic rivet squeezer. I got it on eBay for $200. I've seen them at www.averytools.com and www.browntool.com as well, but they usually run $400-$500 new. The...

Hi Brian. It's full scale. I've got the empenage almost finished, wing kits should be here first week of december.

I'm sorta having fun building it, but...

I recently started working on a Vans RV-9A. Unfortunately (fortunately? lol) most of the fab work is done, and it's a matter of working the parts into the shape of an airplane. I keep trying to...

Hi Tajord -

Sorry for the delay in replying. Those holes were intended for washers. One issue I was concerned about was the edge of the aluminum angle sinking into the wood if torqued in too...

My M12VC died the other night in the middle of some cuts. I checked the brushes - no probs there. I was ready to pull the whole thing apart when I realized the cord had snagged during a rapid.

Walt, a while back I made some DWG files before modifying them for making gcode.

I can't open them right now, but give them a try. I'm not certain they're the latest version, but it has to be...

I just tried with 2005 and 2008 and I can't figure it out either. I always check the box for "allow export" when I save the easm file, and I figured that would make it possible to export files from...

Just the edrawings right now Walt. You can use the edrawings viewer to export the parts to dxf.

Tonight I used the machine to cut out the first batch of parts for 5 LC50B machine kits. You can see 3 of the sets of parts below, which make up the top and bottom pieces of the z-axis carriage.
...

Here's some more pictures. I used the machine to cut holes in the top table skin for the tee nuts. I then turned the table over and cut access holes in the bottom skin.

After painting, I epoxied...

So far the only test cuts i've made have been into the table surface. I cut a grid of mounting holes on both sides of the table. One side has .3" holes for 1/4-20 tee nuts and the other side has 3"...

It sounds like you're making good progress Edmond. Post some pictures when you get a chance :)

Thanks Bill. On the right is the starter tap which tapers to about 1/4" at the tip. The one on the left is the bottom tap, which I use to tap threads all the way to the bottom of a blind hole. I...

Thanks Joe. Are you using the 1/2-8 2 start on your machine? I'll definitely be recommending it to people from now on over the 1/2-10, despite its higher cost.

Thanks Edmond and Thazul :)

In the video I have it running 250ipm rapids on the X and Y with the hobbycnc 200oz motors. The Z is set to 50ipm with an 80oz motor. I've been thinking about...

Video of jog test is now posted.

Good news! The machine is finally "done". My wonderful wife helped me finish the last bits of assembly. I am very impressed with the speed. I'll be posting a video shortly of some jog tests.
...

Thanks Steve. Yes, it was with a homemade tap. I used a few pieces of leadscrew to make a starter tap and a bottom tap. The difficult part was milling the relief lines and screw holes. It's...

I spent most of Friday working with the mini-lathe. The new quickchange toolpost makes things so much easier. I made 3 sets of 1/2-8 2 start acme motor couplers and acme clamps. I'm very happy...

I've been making pretty good progress this last week. All of the painting is complete, and the last bits of the machine are now ready for assembly.

I have a set of nylon bushings installed right now, but I'm totally unsatisfied with them. I have some in my current machine, and they're fine. For some reason the new set I got from mcmaster is...

Walt, try http://www.comptonsoft.com/cnc/Lionclaw_LC50B.easm

That file has the latest models with stl export and measurement enabled. You should be able to open it with the free eDrawings viewer....

I've got all of the main pieces painted. I just need to make a few more HDPE motor mounts, some motor couplers, and some acme clamps and I'll be good to go.

I orderd a QC toolpost and some new...

The only HDPE parts on the carriage are the pieces that clamp around the router. Everything else is MDF.

I setup a painting "tent" in my garage last night to start painting all the parts. It's...

Thanks guys! I'm really having fun with this machine. I used dowel pins on the latest side I put together and it made things so much easier. The parts stayed together nicely without slipping. A...

Hi Edmond. I saw your thread the other day and it looks like you're doing a wonderful job. I think the 608Z bearings should be fine. The old ones took about a year to wear out. The only...

The pipe has been holding up quite well. The bearings have been failing internally. After I take them off I can feel lots of slop between the inner and outer races, and they do not spin smoothly. ...

I don't think there will be any problems. It's possible that not all the bearings will always make contact. On my JGRO and my current machine I've found that the bearings have worn out pretty...
