Looking for LOCAL mentor for TSPROF setup/lesson

[Motega]

No amount of reading, video watching, tinkering can substitute for hands-on experience.

From my setup, almost everything is looking properly setup and angle cube is reading extremely good and repeatable measurements of +/- 1 degree, but a small something isn't right because using a marker test at around 25-30 degrees inclusive (12-15 on eaach side just as a test) I'm way off.

If anyone is is northern NJ with expert proficiency on the TSPROF I would be willing to pay for some time on setup and tips. There is a woodworking shop in Wayne or would be willing to meet up elsewhere.

Hi Frank,
Has Wade been able to help you? I suggest that you set up a Skype session with him. I believe there is something basic that you might not be aware of that you are either doing or not doing. For example, if you are applying a lot of variable pressure on the non-reinforced, flat springs, you will be significantly changing the angle during your stroke. First step I recommend is get Wade to walk you through changing to the reinforced springs that I sent you.

I don't understand how the reinforced springs help, they are literally the exact same plates of metal that are maybe 1/32nd or 1/16th thicker an 1.5 grams heavier as measured by a digital scale. But I did change them and put blue loctite on them. When you said springs I was thinking coils not leaf springs. But anyway, I did change them.
The second point Wade brought up is that the back lifting mechanism really only needs 1" or so of threads exposed and I had more. I'm sure that will bring stability. I think Wade made a good point about the K02 vs. K03 angle lifting bar- at least if the k02 somehow gets stripped it can be replaced as opposed to the rack and pinion, but I think I would have given it more consideration- maybe my mind will change after using it for a while.
My last bit of confusion is that it seems like behind/under the rest adapter mine is perfectly level (not complaining!) using a angle guide.
Anyway, I put the new springs on, they are dry now, and will try to sharpen. My first attempt wasn't really that bad, just that I basically needed to put a whole new bevel on an old kitchen knife and was hesitating to get aggressive with 100 grit which is what it needs to set a new bevel.

It's hard to believe that an extra gram of metal is going to impart that much more stability, but I guess we will see! I sent you the pic 2 days ago with the reinforced spring so not sure why you sent it out- but it certainly shows how much you care about us! Thank you George!!!!!

How does one get the springs you mention, as I sometimes vary my pressure without intending to.

 

[Motega]

Just order them. I think George sent me extras before he realized I found them. I can forward them to you if he allows me to and pay him for the parts and cover the shipping on my end.

Frank is right. Go to www.statesllc.com and click on "Components" at the top of the home page. It takes you to the catalog of clamps, holders, reinforced springs and fixing units. Select either the reinforced springs for single clamps or reinforced springs to double clamps. I have plenty in stock. Be sure and select the right ones. If you bought your unit before January 2018, you will need to order the older springs.

Sorry to get technical on you, but when you increase the thickness of a flat spring by 50%, you double the spring constant, meaning you make it twice as stiff. Hooke's Law : Force = - k * X where X is the amount of deflection and k is the spring constant. From this law, doubling k will reduce the deflection to half for the same Force.

(Sorry, I'm an old Physicist who used to teach Physics at the university level)
BTW, I cannot see a 50% increased thickness on 1/32nd of an inch from a picture. So, I couldn't tell if you had mounted the reinforced springs or not.
