22x25 1.25Mod Gear Rack Straight Tooth and the pinion and is driven by a 550mm long timing belt with a 5:1 reduction. 90T to 18T timing pulleys in the reduction box.

Sorry, for the late reply,Thank you and yes I did all the fabrication work myself with the exception of the electrical control panel, I had the sheet metal cut and bent by a shop local to me. I did...

Sorry, for the late reply, I have no spring tensioning on my rack system, the rack was placed and dowel pinned in place using a dial indicator and the traveling along the bearing rail sub-system. ...

And finally we are back to the finished machine. I have a few other projects to do, like I need to make a new workbench/Assembly table now and get a little more organized. And now that I've...

Next up, I used 3/4" a cabinet grade plywood that is marine grade glued. I clamped it all down and used the router to pilot drill all the holes and finished it manually with a hand power drill. I...

Here are some additional pictures of finished controller cabinet wiring. Also you can see that I have a coolant radiator for the spindle. All the fans are 110v AC fans. Note: I initially used 2...

First, I apologize for not updating this in a more timely fashion, it's been pretty busy with real work and being out of town for 3 weeks. So in these next few updates I should have everything...

I want my controller box were all my high voltage mostly AC on one side of the box and separated by some kind of wall and all my lower DC voltage on the other side. I've read where others have had...

Now beginning to start the process of threading all oil lines, wiring and coolant lines, etc. In the beginning it looks like a mess but, I figured I may as well show you the messy parts as well as...

Hi Wizard, Yep I put the product details above to Pete's inquiry. Thank you, but no, not a professional welder, but I will confess I learned how to what was called in the early days HeliArc welding...

Pete, I wasn't trying to avoid not telling you what product I used at all. I in fact talked to to folks at Precision and as luck would have it for me, they where heading out to a big 4 week job at...

Yet more fabricating work for the fail safe stops, limit and homing proximity switch brackets. It's the little stuff that chews up time!

One additional piece of information that I learned, many machine tool re-builders use this stuff as well.

I not sure what the the rules are yet :) for adding product links, etc. But go to precisionepoxy dot com under product list under the "Leveling Epoxies" - SC-15P. I did a ton of research on this...

I swear at this point in the build I was wondering if the fabricating would never end. From here on out everything else was sort of designed and built by the seat of the pants as I did not go to the...

Yep, I hear you. This stuff is supposed to be designed for machine tools and guide rails, but like you say, I am going to keep a careful eye on it. You'll note that I did the X axis entirely...

I had one of my son in-laws come over to give me a hand to put the gantry and the the Z axis together as this was clearly a 2 man job. It was quite exciting as this was the first time to really see...

The painting begins, I really couldn't spray paint this as I would had to cover up my entire shop, so just did it the old fashion way and brushed on with a good oil based brush. I was initially...

Z axis assembly is complete here.

So my initial design for the Z axis was to use .500" aluminum plate, but that all changed when I was given approximately a 4' x 4' x .75 thick sheet of aluminum plate, so I had to go back to the...

Some how I think due to a planned vacation and not taking the time to takes photos (late nights) each step of the way I managed to only take 2 pictures of a finished gantry. It is made from 4x8x.25...

It's a very interesting topic. Before I started doing any welding on my components I went back and had to refresh my self on how I could limit distortion in welding components, as the distortion can...

Next up, I began to mock up the gantry uprights, the angle iron is 5x5x.312 wall, the main upright is 4x4.25 wall and the plate is .500 thick. Not show here but there is also a piece of angle iron...

Now the beginning of the hundreds and hundreds of holes to drill and tap. In the first and third picture you can see that I tacked on some angle iron on the ends of the right side and strung some...

I can't remember who it was that posted the same thing I'm about to here (I believe they were in SC), but here in the south, humidity is something we just have to live with. After about 2 weeks this...

So in my best effort I was hoping not to have to do the epoxy bed for the Y axis rail guides, but it was out about .010 thousandths in the 11' length and it was simply going to be very difficult to...

Thanks guys! Continuing my frame adding cross bars, tack weld first and make sure it's all squared. All this extra work making sure everything is level, squared up and flat paid off in the end as...

Next I laid out the other side, then I tacked on some angle iron pieces to help support the cross bars. The last picture is were I stood the sides up and began placing the cross bars and the...

Next I laid out the sides, the top rail is 3x5x.25 wall tubing 11' long. I spent hours on the floor, leveling, squaring this out using chunks of 4x4 wood and door shims. You find out pretty quickly...

It all started with me putting up my first drawing on the wall and on to the feet and legs. I used a pair a very large washers and grade 5 bolts and after welding, I chucked them up in a buddy's...
