Being relatively new to the game I had issues sharpening to begin with. These are my findings, although probably not 100% correct.
One of these is the baby. You can get them here in the UK, this was just the first site I found.
Check the angles against the jig to make sure the jig angle is spot on. I made a jig very like the Cap'n Eddie jig which is pretty much foolproof.
Also make sure the sparks are coming over the top of the tool. If they are not, the edge is not touching the wheel properly.

The first two are the long ones

There the tools I know one is the skew chisel and a scraper the rest are 10mm and 13mm two of them are long ones

I am also a beginner but I would say
1,2 ,4 &7 are bowl gouges.
3 is a skew
5 & 6 are spindle gouges.
8 & 9 scraper
10 & 11 are parting tool

3 is a skew
4,5 , 6 & 7 are spindle gouges. (the shoulders on pic 4 look like it has been over ground as they are concave. it should be either straight or slightly convex i believe)
8 & 9 scraper
10 & 11 are parting tool

There are numerous sharpening systems on the market. Grinder jigs that clamp to a bench under your grinder seem to be popular. be careful when grinding not to let the edge of the tool get too hot or it will ruin the tempering. Another system that is popular is the wet stone system which negates the heat problem. Google Tormek and you will get an idea of what I mean (other wet stone systems are available)

Ye I seen the tomek system it's a bit to much money at the moment the is a guy on eBay sell nice
Home made tru grind jigs so ill try the cheap one first but with the gouges what sound they look like

Hi NC

I don't know what the Rowney jig looks like but from your photos it looks as if you are sharpening the gouges as if they were pencils. By that I mean that you are rotating them about their long axis.

Look at this page. The first video is what I mean. What you should be doing is shown in the second video.

When you are finished they should look like http://www.woodcentral.com/newforum/grinds.shtml

Thanks for posting that Bill. The second link shows perfectly the convex shoulders I mentioned.

Nippy, for bowl and spindle gouges its easiest to use a purpose made jig which has like a dog leg. For a normal bench grinder something like this set will be a great help

I was lucky enough to get a Jet wet stone system (very similar to the tormek) with all the jigs for wood turning tools on Ebay for £100 so they are out there.
http://www.youtube.com/watch?v=tUzTI6ayMW4 this shows a comparison between Jet and Tormek

That second link is perfect form me it gives me an idea of what it should look like

[Nippychippy]

Hi, I had major problems sharpening chisels when I first started and tried various methods with limited success .
I eventually bit the bullet and forked out and got the Tormek system and associated jigs. I have not looked back since, producing good sharp edges of the correct profile is just so simple. I know that the Tormek systems are very pricy but the investment has been well worth while.

Ye some one is trying to out bid me on eBay
