Tumbler Build - For cleaning plasma cut parts.

Today I made some sprockets for the roller door chain drive,



Took me five revisons to get the sprokets sitting on the chain correctly. Plasma really is a blunt axe but these should work fine.





I will weld on a piece of pipe with two grub screws to hold them onto the shafts,

Is there no end to your talents :woohoo:

Lol Thanks Clive. In the next couple of years I have some pretty big projects lined up. Stay tuned.

have to give you credit you get into some pretty cool builds. sprockets would not have been on list of things to cut with plasma but it looks like you proved me wrong in my thinking

Sometimes you need to find a way to make the tools you have work.

The sprockets have a bit of taper. I had to lower the feed rate right down to try to eliminate most of the taper and it worked, also I had to reduce the scale slightly of the sprocket diameter to work with the plasma cuts. If I had them laser cut they would of been perfect the first time but I am sure they will work fine in my roller door application. I would not want to use them for a motor bike or such.

I see building a laser cutter in my future

Pat yourself on the back as i can not reach from here!
Nicely done.

Thanks Tom, It means much to me coming from you.

we got a new one a few years back the laser cutting is a nice process to have. the one we got was a Co2 laser but i think the fiber optic ones are getting a lot better. the Mitsubishi ex series was what they got and it has two 5 x 10 tables. the one can be loaded while the other one is cutting and has a pallet changer so it can cut non stop. nice machines.

I dont think the one I will build will be as fancy but it will be far far cheaper!

I was quoted around $900K for a similar unit to the one you posted a picture of. Problem I see with all those high dollar machines is the vendor lock in. I have grown to loath proprietary control systems! I will never buy something like that, that I need to get a special technician out to change a simple setting! At $500 an hour as well. No Thanks Lol.

A bit off topic, but just goes to show to what extent i molest my brain when building something, granted i can find the parts:

Left are black M5 screws, right are white M6 screws, all with 4mm allen wrench.

Above 4x M6 screws, below is an M8 screw, all with 5mm allen wrench.
Up until the last 3 machines i built, looks were not on the priority list at all, functionality was. Now that has changed, but it made building the machine much more time consuming.
