Blade thickness
« on: January 23, 2012, 06:41:36 am »
I have just received my first lot of FD blades from Mike ( great service by the way ) and having a problem with them coming loose. I clamped them with the same tension as my previous blades which I got from Hegner. I think I have sorted it now but am wondering if blades from different manufactures vary in thickness. No compaints about the FD blades by the way, problem is the idiot working the saw. 😚

You might solve the problem by running a sand paper a couple of times through the blade clamp. The blade will get more grip afterwards.

Many blades have a coating on them from the manufacturer which retards rust.  I keep a small container with a piece of sponge in it and some mineral spirits and before I use each blade, I dip the ends in it and then wipe them with a paper towel to remove any of this coating that they may have.  This helps a great deal.  You may also have to clean the blade holders on the saw in the same way, as the oil from the blade may have contaminated the holders on your saw.  It only takes a second and the results are great.  The sanding works well too, but if there is a coating on it, it could still slip even though you sand. :)  Hope this helps!

Yes, different blades from different manufacturers do vary in thickness/size despite the same numbering.

Torsten's advice can work for you.  Others will run some sandpaper along the ends of the blades to make them a little rougher, and some will wipe the ends of the blades with a little bit of mineral spirits to remove the oils left over from the manufacturing process.  

Any or all of these things should help out!  Good luck!

Oops, Sheila was a little faster on the trigger!  :D

Thanks for the replies. I will use some sandpaper and clean with mineral spirits as suggested. As an aside I like your website scrollgirl, when I finish my list of ongoing projects which at my present rate may be some time ,will be looking at some of your patterns.

Normcat, I don't ever recall hearing what kind of saw you have.  With my Hegner, the thickness of the blades makes no difference because you clamp done on it anyway.  But the Delta P-20 is a different story.  Each blade requires a different adjustment.  And they can be the same blade out of the same pack.  Really not happy with the saw...  So you can guess which saw I use the most  :)

hmm, Chuck, that can also happen with the Hegner system. The screw that is responsible for holding the blade wears off over time. Even our Hegners have the smallest bit of vibration and the torque on the blade does it's job too.
I have had some breaking blades on the weekend and had to sand the screw a little bit myself. Didn't happen again so far.

That is the only adjustment I have to make on my Hegner, but that is only once every six months or so.  When I do check I put lock tight on it before I put it back in so it does not come loose except when I want it to.  Now if I could only get the P-20 to be so cooperative.
