I've made a few bandsaw boxes and I understand your problem as even a quarter inch blade is too wide for some of the curves I attempt. I now use a one eighth inch blade which I get from Ian at Tuffsaws. The one he recommends is the 1/8" x 14tpi SuperTuff Carbon Bandsaw Blade and for the 2552mm that I require I pay £14.00 each plus P&P & VAT.
If you haven't used Ian at Tuffsaws before he can be contacted on 07896 058499 or 01443 819261 or you can email him at
[email protected] and he comes highly recommended.
