Lathe tools

Hi,

I have some carbide inserts, but no holder for them. So idea was to create such a tool. I have some leftovers of PA6 Aluminum and decide to use it.

First tool is normal one installed in lathe tool post.

Cheap rotary tumbler

Hi,

Sometimes I cut a lot of small aluminium parts. Deburring them take a lot of time. That why I need something that will help me to do it automatically. I made rotary tumbler.

 

Lathe

Hi,

Once in the past I sad that lathe is one of the most important tool in DIY workshop. And this did not change. That why I decided to buy again lathe, and this time I will not sell it.
I was checking www.allegro.pl and looking something affordable for me. I do not need big one in this moment. And PROMA SM - 300E show up. It was quite old (2006 production), but from pictures it looks OK. I decided to go and see it, and it look that it was not used! Everything was looking like new, and it still was in original box. I decided to take it, prize was very good in my opinion.

New dust foot

Hi,

Whit new machine I made much more Plywood, MDF and dust board cutting. There is a lot of dust and chips flying around. In whole room there was mess. So "dust foot" was a must have thing.
I had to remove Z axis from machine.

On the bottom of it I drilled 4 holes and taped them M4.

 From 4 mm Aluminum plate I cut holder and screw it to Z axis. This will be permanently installed on machine. Additional hole is for my vacuum hose.

Biggerc CNC - update

Hi all, 

It was long time as I was not posting here new stuff. But I had so much things to do, sweet life in countryside ;) Despite there was no publications I was doing some small things. 

But Fall came and I will have more time for my hobby. 

Modernization of my old CNC end with complete rebuild of everything. Only computer did not change Below some photos. 

 New driver with cooling fans.

Still missing: switch limits, E-stop button, LCD holder.  

Vacuum table

Hi,

Sometimes friends ask me if I will cut off the PCB on my CNC. So I use double-sided tape to hold laminate on table. But this is not good way. Only THT elements could be cut like that. Sometimes it loos grip, it is hard to do 2 layer PCB. The most problematic thing for me is to use engraving cutter and not destroy it. I have in my workshop 2 vacuum pumps.

So I can use them. Conclusion is clear - to build vacuum table. I check internet for some examples and I made first trial to build it.

CNC almost done

Hi,


Last days I do not have much time to work in workshop, but I try my best. So I am still doing modernization. I bought 2 ball screws and nut to gate (Y axis) move. I had to create mounting bearings and nut holder. I made it on my smaller CNC.

Lathe body - epoxy + profiles

Hi,

I had to sell my lathe some time ago. I had no choice but I think that it was big mistake. This is one of most important tool in workshop, when you like to build something more complicated.
So I have to get one in my shop back. I can not afford to buy new one. I am afraid to buy used one, not to get junk. So why not to try build one.

I have some spare 45 x 90 mm profiles, 1000 mm length. And a lot of smaller parts.
From my friend Jarek I have 4 kg of epoxy resin and hardener. It is a little bit old and I have to use more hardener that was in original recipe. Sand is no problem.

I decided to use mix 20% of epoxy and rest of sand. I would like to have profiles filled up very precise.

Modernization ?

Hi all,

While working on the current project I do not know whether it should be called "modernization". At the present moment the machine is completely rebuilt, and from old machine, I used the electronics and one propeller. Below the promised pictures.

 This is how it looks now.

Modernization - next steps

Hello,

I have problems with my camera and I can not show current status of the machine, but it is almost ended. Some old photos I found I will share now.

But in that moment I have only missing some belts and cables to get it work. I hope I can sent post more frequently in future.

Modernization - new progress

Hello,

I used some free time and opportunity that I have workshop at home and create some new parts. I need to do modernization of this CNC as fast as possible.

Main profiles to gate are assembled. There will be additional reinforcement added to back of it. On left side I made from 15 mm thick aluminium place for bearings for screw. You can not see it, but it have place to install stepper motor. On third photo is additional cover to bearings and nut holder. I used screw and nut  (Tr 14x4) from old machine. If I have free money I plan to install there ball screw.
