Thread: 'Plain' Blades v Spiral Blades.

We have a small regular attendence at our Scrollsaw Club, about ten bodies. There are two who have been sawing longer than the rest of us. These two use only spirals, won't and say they can't use other than spirals for everything. Others of us, relying on the magazine information that we read, stick with plain blades and have been having a go at them for the spirals use.
The other day I was attempting a 'compound' cutting project - 30 t0 40 mm stuff - and found that I was producing 'funnel' shapes. Yes, I'd squared the blade and confident that I was not pushing the piece unduly. I was using a WMS machine which I'm pleased with.
So, at the next club meeting I tried the three machines we have, GMC, Delta and Riobi - squared the table, etc. and using No. 7 blades - with the same results - funnels. This was with plain blades and the timber was two pieces, 20mm and 30 mm thick. Two other members had a go, same result. We then changed the blades to spirals -2/0's - and although the cuts were thicker we got acceptable results!!!
Whilst reluctant to use spirals, other than for portrait style, I must admit that spirals will be the way to go for me with the compound jobs.
Needless to say the 'spiral' pair are still chuckling.
