Like your clear descriptions. Looks like your wheel has lateral runout.. which is correctable.
what is the angle? What is the purpose of the side to side motion? wouldn't that change the angle?
you have some great videos. thank you
Thanks so much for the compliment. Just hope they help out yourself as well as others.
I am just starting to turn a good bit and am finding them hugely helpful.
Are any of your lathe tools from Harbor Freight?
I got mine from there as I am a novice turner and figured it's not wise to invest $1,000 into tools if I'm going to be terrible at it.
Anyway, the Skew that came in the HF set had terrible bevels that had what I could only describe as a "crater" in the middle of both sides. Today, I wound up taking my angle grinder and with a few passes on each side followed by a dip in water to keep the temperature down, I got my bevels looking flat and what I would imagine to be normal. I have been using it as it came for quite some time now, and it was only today that I got fed up and made an attempt to correct the issue.
Now, I sharpen my chisels with a good old 3 step sharpening stone going from Medium to Fine. I use a liberal amount of Aero-kroil and get to work. My chisels, especially my Skew, are sharp enough to shave with. I'm not saying anything here in order to gloat, I just wanted to explain myself before I ask you a question.
Is what I'm doing by sharpening with a stone going to compromise the integrity of my tools?
I asked another guy the same question and I'll withhold his answer until I hear back from you, if indeed you respond.
Thanks! (I'm a long-winded kind of guy, sorry about that)
My first set of lathe tools were from Harbor Freight as well. they were very inexpensive and was a great way to test the waters before tossing money into the money vortex of the lathe. The Harbor Freight tools will take a nice edge but as you will soon discover they will not hold that edge very long. The Tools I use now are Woodriver (Woodcraft) and Sorby. I would highly recommend you check out Benjamin's Best Tools sold by Penn State Industries. They are a really decent tool in the budget price range. I own some of their tools and have never had a problem. When you move on to using a grinding wheel for shaping and sharpening your tools you will make mistakes and it is much better to grind away a cheaper tool than an expensive one.
As far as sharpening with a stone....I can not see where it will cause any harm to the tool but I think it will result in a lot of wasted effort. There is nothing wrong with touching up a parting tool or a chisel with a diamond card or stone as long as you do not let the tool become too dull. Once it does become dull it will take a lot of effort to get it sharp again. I can not see sharpening a spindle gouge or bowl gouge with a stone. It will become very difficult to maintain a consistent shape and bevel. This is why I use a grinding wheel and the Wolverine Jig. It is quick and most importantly repeatable. There are many times where I have to touch up a tool in the middle of a project. My setup allows me to do it in seconds. I would not want to have to stop and do it by hand. Again a few swipes with a stone on a parting tool is fine but becomes difficult with other lathe tools. Difficult, not impossible. It all depends how much effort you are willing to put out. I highly recommend an 8 inch grinder (not a 6 inch) in order to maintain the proper geometry of the tools. Start off with inexpensive stone wheels. Eventually you may choose to move up to the diamond wheels as they will save you money in the long run. You will soon find out that the lathe is the least expensive investment you will make in this hobby. It is all of the little extras that will run up the cost.
I hope that you found this helpful. Best of luck with all of your woodturning endeavors. Don't hesitate to ask any more questions.
what grit diamond wheel is that? Do you ever do any further sharpening with very fine grits and polishing with a strop?
First off it is not a Diamond wheel but rather a CBN wheel. CBN wheels are preferred for this type of sharpening. The wheel on the left is an 80 grit that I use for shaping a new tool. The wheel in the right is 180 grit. All it takes to re-sharpen is a light touch on the 180 grit wheel for a few seconds and you are good to go. Some people will touch up the edge during a project by hand with a diamond card. I have done this on a few occasions but find it to be the exception rather than the rule.
@@daveswoodshop782 thanks for the info. Did not expect such a fast reply. I like your videos!
What grinding wheels do you use to sharpen chisel?
The wheels are CBN and I sharpen with 180 grit wheel. The wheel on the left is 80 grit and I use that for shaping my tools.
Is that jig necessary or can you use a standard rest?
It all depends what you mean by "standard" rest. The rest that comes with many grinders will not allow the proper angle at the point of contact you need to hit. If yours does you will still have to eyeball the "skew" angle. It can be done but it is way easier and much quicker with the jig. When it is quick and easy you tend to touch up your tools much more often, even during a project, in order to maintain a sharp edge. When it proves to be a chore to sharpen we all tend to do it a lot less resulting in inferior cuts. The Wolverine Jig is a one time investment that will deliver years of service and convenience.
@@daveswoodshop782 Amen to that!
I turn bowls on my lathe, and I'll be the first to sing the praises of a jig to get a consistent "fresh" edge on my bowl gouges...even during the turning.
the sharpening wheel should it not spin clockwise away from you ?
No, it rotates towards you from the top of the wheel. That is how it is able to sharpen the tools.
