Blade Numbers

[Canuck45]

Hi

 

What's the difference between a #1 blade and a 2/0 blade?

[Dan]

It depends. If you look at Flying  Dutchman 2/0 reverse tooth and Olsen 2/0 reverse the kerf and thickness are the same but the TPI is significantly different. No. 1 blades are generally a slight bit larger than 2/0 but that can vary between manufacturers. If you are considering buying one or the other check out the blade chart for the manufacturer for recommended use. That said, if one works better for your use just go with that blade size.

I ordered a few different ones from the same manufacturer. I chose Olson, chose whichever you want.  I wanted to see and try different blades to see for myself what the difference was. It did really help me understand.

in flying dutchman reverse tooth blades, a #1 is .026 wide,.011 thick, has 13 teeth per inch and 7 reverse teeth. a #2/0 is 022 wide, 010 thick, 15 teeth per inch, and 10 reverse teeth.

heres the list for FD reverse tooth blades:

Thanks for the info. I will print this out and save it.

I was not able to find any specs on FD blades.......where is it listed?

[JustLarry]

Every order I have received from Mike's includes a brochure showing specs for all of the blades.

at Mike's workshop site select blades, select any blade and the specs for that "style" of blade will be shown.

I looked on the latest Mikes Workshop page and the chart that Mike used to have there is gone. Wooden Teddy Bear bought Mike's business. I looked on their site and didn't see it either. Googling the chart resulted in the Olsen chart and the JGR Tough Little Blade chart.

Wooden Teddy Bear may have the Flying Dutchman chart, but they aren't displaying it.

At Mikes and WTB the specs are shown for each blade type.  Select the blade and the specs for that blade are shown following the description of the blade. 

Here is sample from each site:  I looked at these just a few minutes ago.

I saw those, but Mike used to have a PDF of the page he would send out with each of his orders. That seems to have disappeared.

One of our club members has always said to ignore the blade numbers and only compare the TPI and other specs. 

I am doing a presentation tonight for our new members, part of the discussion will be this blade topic. I get a kick out of the comments people make " my FD 2/0 blade cuts so much faster than my Olson 2/0"  it is therefore a better blade. The reality is the Olson 2/0 has 28 tpi vs the 15 on the FD.  Who's blades are better is a different discussion, those can get ugly.

[don in brooklin on]

Great idea to copy out the sizes etc.

I teach the Beginner scrolling course at our club and I give out the Olsen chart found at https://www.olsonsaw.net/wp-content/uploads/2016/01/2015-scrollchart.pdf

I am a big FD Ultra Reverse user so I have every one use UR blades. #3 for BB and #5 for compound.  I give out the pricing sheet if I have them but with this idea I I have created a PDF from the web site.  May need some tweaking so if any one sees an error please let me know.  I want to make into a spreadsheet eventually. 

When I discuss blades I do emphasize that they should try other blades until they find one they like for the work they do.

This certainly makes a lot of sense. Matching the thickness of material being cut to a blade with the correct number of teeth would make a great difference in quality of finished product. Thanks for opening my eyes to that Rolf.

On the subject of blades and mfgrs. have any of you ever tried blades from Otto Frei? Here is a link to a page on their website. I bought 2 gross of the 2/0 blades from them when I first got interested in marquetry and the instructor recommended them to his class. It seems that they are priced close to the more popular FD, Olsen, and Pegas blades. So far, I have had good luck with them but I'm not the most experienced or high volume scroller here by any means. Please let me know what you think.

Wow, those are some tiny blades!  I can't imagine trying to use an 8/0 jewelers blade in an electric scroll saw.  But it might be fun to try....once.

Well, they specialize in tools for jewelers. They have larger sizes too.
