Gouge for a Lathe the good and cheap way (Oland Tool)

Good gouges are expensive; but not this one! I was happy to discover this great DIY lathe tool. It's called an Oland tool http://www.aroundthewoods.com/oland.shtml it was invented in the 1970's by Knud Oland.

Common wisdom tell us you can't have it all; you must choose between three factors: you can have it inexpensive, high quality, and easy; but you may only choose two out of three.

But with the Oland tool you can have it all!

This tool is cheap to make, easy to use and functions well. Constructing this gouge involves regular shop tools and common, inexpensive materials.

The parts are:
-a big dowel (free from the scrap pile, you could even substitute this with a scrap of 2x4)
-a 16mm X 30cm steel rod (18"x3/4"): 300 yen
-a 6mm (1/4") lathe blade (from a metal lathe): 2000 yen but probably way cheaper in your country. This was too expensive for me so I used a hardened steel concrete nail instead.
-a 5mm .8 thread machine screw (or a 1/4x20 thread): there's probably one in your pocket right now.
-2 meters/6 feet of thickish 1~2mm 1/8~1/16 steel wire: very cheap
=Not much money.

The tools are:
-drillbit the same width as your steel rod (to drill wood).
-6mm or 1/4" drillbit (to drill steel)
-5mm .8 or 1/4x20 thread tap
-5mm .8 or 1/4x20 bottoming tap (Mothflavour2 suggested a workaround so you don't need a bottoming tap see step 4)
-drill bit appropriate for your tap size.
-a drill
-a grinder with a narrow wheel.
That's all folks!

Thanks for sharing this. I'm sure these will be great tools even if some of the tool collectors at Flickr's Tool Porn won't agree. And concrete nails are such a cheap source of hardened steel!
Those interested in a treadle wood lathe should check here.
Thanks!

I have heard and read that many turners make these from tool stock. I wanted to make some for my students because the oland tool is said to reduce catches.  I recently purchased some stock from Enco (#110024 - 3/8" M2 round tool bit) to make oland gouges, but I have not made them yet because I have never seen a good picture of an oland tool to match the grind.   Your photos are very clear.  Are the wings of the bevel really that steep?

I'm glad to hear you want to make this tool!

You say you "have not made them yet because I have never seen a good picture of an oland tool to match the grind" 

My advice is simply experiment. The tool is cheap; especially if you use concrete nails. They're like less than 10 cents each.

Yes, the wings of the bevel are pretty steep I guess. I don't have much experience with gouges or lathes... My gouge is roughly modeled after a "fingernail gouge" but it's so easy to change or replace. No need to hesitate.

Maybe the best thing to do would be to turn the tool into a class project! Each student could make an Oland for them self and try different gouge shapes. Then you could compare all their prototypes and see which works best for what.

Have fun!

I've never worked with a gouge as small as 5mm...does it offer a lot more awesome?

looks like a great tool!

My girlfriend says I should admit that I have no idea what I'm doing with lathes or lathe tools. That said, it seems to work just fine. My lathe is treadle powered (more on that someday) and somewhere I read that a small gouge is better for this low-power system.

Generally the Oland tool catches less often if ever and cuts faster than a larger gouge.

So overall, yes, I'd say it does add a lot more awesome.

Fantastic!  Treadle power is a perfect explanation of how this is extremely superb! :D

Interesting tool!
I've discovered that if you don't have a bottoming tap, you can still make the threads all the way through by simply drilling the hole all the way through the other side and letting the tap thread through the whole piece.  That way, you end up with two tapped holes, both of which are completely threaded, yet you still have the option of only using one.
