Got a home late last night and only got the bottoms done, but progress anyways. Did a clean up pass and cut the edge relief and insert pockets. Thickness is +-.1mm so far, I'm pretty happy with that. A lot more ducking around than I'd like, but I'm not going to complain for the first time. This pair...

Thanks for the ideas guys. How many springs are you using, how far apart?

Cornice, glad to hear that works, that was my plan B if I couldn't get bungee to work.

Ya, the whole learning CNC'ing thing is a massive project of its own. Getting it to cut shapes is easy, but ridiculous how many variables there are to arrive at good results. I've been using cheap straight shanked carbide bits almost exclusively. I have tried a few carbide upcut spirals, but they ju...

I know, I know! I still haven't put limit switches on my machine, or finished the door to the control panel, or hooked up the spindle speed controller I have all the pieces for, to give you an idea where the todo list starts. All the wiring is run, I just have to mount switches and hook things up. A...

I like that idea, would definitely make setting up and running go faster. Plus would be really cool when random people drop by to make it look like its just a big video game. I really want a pulse wheel for single step when zero-ing z since a touch off plate is a ways down on the to do list still. C...

One of the few perks of my day job is access to some heavy steel fab equipment. One of the fabricators burned those for me out of 1/2 plate and formed them on the big press brake. They're 2 pieces each with a seam top and bottom. And ya, the wireless keyboard is nice to have for sure. One day I'll g...

Bit more work done on the press. Getting there. Priced out aluminum, decided oak strips will have to be just fine... http://forum.vwsport.com/pics/data/500/medium/IMG_2131.JPG Hose is ~9.25 flat, press cavity is 14" wide. Going to have to get creative with the ends to get them both to fit. http...

The sourcing of parts on ebay has already started (I'm gathering links)... unfortunately ebay.co.uk is about a 1/3 more expensive than .com. Import direct from China is probably the way I need to go. I feel your pain, same goes for .ca vs .com. Best bet would be to contact the seller directly. Its ...

I wrecked the last one and it hurts. I am squeezing a beer bottle for dear life while bitting my lip, and holding my breathe every time the toolpath is running. You stuff looks awesome man. Just had to reply because that statement sums up my CNC'ing experience exactly. Hours to make something that ...

The machine I built sounds very similar to Twizz'. 20mm linear rails on x with two bearings per side, and 16mm on y with 2 rails and 4 bearings total. Main frame is steel, but I used aluminum in the gantry cross pieces to keep the weight down a bit. No issues at all so far, and linear motion stuff i...

Heavy frames absorb vibrations better, and generally make the machine more stable. For ultra precision machines bigger heavier parts will allow you to hold ultra tight tolerances better, all other things being equal. I worked at a place that ground carbide to .0005" tolerances, and they'd run t...

I have to see how I can improve the separation of very fine dust (MDF) but for now it's OK so I'm gonna work on hard-ducting the system in order to improve the suction (less elbows, less flex hose -» more efficient) Hey man, I've got an almost identical setup on my rig, was the second thing I made ...

Top half is done for now. Bottom mold up next. Waiting for some fittings to start putting the fire hoses in. Lots to do, and there's snow in the mountains already.

Hey falls, I watched your build thread pretty closely before starting this press. You may notice some similarities in the whole layout.... What's the wall thickness on the tubing you used? Mine is ~6mm wall and ~51mm x 76mm structural HSS. Ran a quick FEA study on it that says it should be more than...
