Building a cabbing machine
« on: May 13, 2012, 08:45:07 PM »
Hey guys!

Thinking about building my own cabbing machine like this guys http://gemstone.smfforfree4.com/index.php/topic,6282.0.html

maybe a little smaller though ::)

One thing i've been wondering is if i could glue some silicon carbide sandpaper onto a homemade wheel and use that instead of expensive diamond wheels.

Cheers   ;)

Hi Daniel  beers

That is an awesome machine & ingeniously built.  ;D I dont know if gluing sandpaper on them would last long at all. Maybe a better idea is to get expandable wheels or cheap ones.

If I was going to build one, I'd still go the 10 wheeler as its a great idea. I would be tempted to have sleeves with grub screws in order to tighten between them tho even if only using 2 or 4 sleeves this way with the added left / right hand threads on either end.

Whats the cheapest expandable wheel you've seen? most I see are nearly 100 bucks, and for a 10 wheel cabbing machine thats close to $1000 just for wheels  :o

Daniel, I did that when I first started cabbing, thought it would be a cheaper alternative, the paper stayed on the wheel for about five minutes, once it got too wet it just fell to pieces.

you can get cheap diamond wheels for 80 bucks not the soft back type but you could use the expander drum and silicon carbide paper for that .

At the risk of blowing our own trumpet, we offer a kit of 6 standard diamond wheels or more at $90 each (either hard or soft/flex in any of our stocked grits) - if you take off the additional club discount (or ALF discount) at 10% off for order over $500 and you are at $81 per wheel and you can use either type of wheel for a complete set up.

Expanding drums are still a good option worth considering though dont rule it out completely.  Although expensive to buy, the consumable cost thereafter is cheaper.  And then at the other end of the scale, you could consider sintered wheels - expensive so possibly out of your budget to start with but for people who plan to do LOTS of cabbing, they will last and last.

For the very budget-conscious, you can try recoating your flex wheels for a second life - can take a bit of mucking around to get the epoxy mix right but if you are into DIY, then you could have a go.

Is there a thread on how to do this?  Can someone start a new topic to explain how this is done and what materials are needed?

Apart from that, a set of sintered wheels would be a my dream Christmas wishlist.

Daniel, If  you don't want to spend the bucks on a small combo unit I think  the best bet is to get a cheap 6"  grinder from Bunnings and replace the wheels with  green lapidary wheels for your course grinder and use a 2nd motor to run an expandable  drum setup.  You only need one expanda  wheel,  just keep changing belts.  Silicon carbide belts are quite cheap and last ok. Later you can change belts to diamond.
 Alternatively you can use paper  (wet and dry) on a rubber backed disc  using peel on peel off glue. It will work but your'e changing  paper a lot.
 Main thing is getting a nice water drift to the wheel and stone and a tray to catch the water and sludge

I tried fiddling around with making gear with mixed results, mixed between poor and hopeless but when I bit the bullet and bought a Cabking the fun really started happening.

Six wheels with a flat lap and/or polisher on the end means that you can go from rough rock to shiney in one go without having to change wheels, drives ect, means more time enjoying my pastime instead of trying to re invent the wheel.

Since buying the Cabking I have moved on to some more specialised gear to the rocks that I prefer to bring to life gear but the Cabking was the best value for money that I have in my workshop and it still get used often, my grandkids are learners...lol.

BTW..I don't work for Cabking, just my thoughts ...good luck.
