Dremel Moto-saw MS20-01 question

[Runa]

Hello All,

I am new here and just picked up a Dremel Moto-saw MS20-01 to learn. How can I compare the pics that came with it (MS51) to #3?

I seem to break them easily while trying the turns as gently as I can using the loop method. Any advice would be appreciated.

I also just realized that it uses pin-end blades only so assuming that the intricate designs is hard since the hole that need to be drilled in between wood is going to be larger?

I checked out dremel's website (https://www.dremel.com/en_US/products/-/show-product/tools/ms52-fine-wood-cutting-blade)

they list the blade thickness as .025" and 18 teeth per inch

This is a blade chart from Olson (http://www2.woodcraft.com/PDF/Olson-scrollblade-chart.pdf)

a #5 reverse blade has a thickness of .014 and 12 teeth per inch. 

A size 12 blade is .024, about the same as your dremel moto blade. I don't think I have ever used a blade that big, maybe if I was cutting a 2x4. 

Watch as you cut your curve. Does the blade start to twist? If it does you are trying to cut too tight of a curve and the blade will break. The trick to turning is that the blade has to wiggle in the kerf (the space that the blade leaves behind). If it is binding on the wood it will twist the blade causing extra friction and heat and the blade will break. Sometimes slowing down your turn will help.

Thanks MrsN. I am still learning how I can buy smaller saws for the moto-saw which requires pin end. I am assuming olson's pin-end saws will fit.

When in a turning corner nibble at it a bit to widen the turn for your blade .This will keep the blade cooler and make the turn much easier.

Thank you :-) Learning to scroll saw is just so amazing. I made my 3 year old a simple elephant puzzle and he was thrilled.
