resawing

[aramco]

hi i am trying to resaw 9 inch x 4 inch 200 year old pitch pine from an old church, with a 3 tpi 3/4 blade from tough saws in my record power bs300s band saw, and am finding that after each cut of the 4 inch thickness I have to clean the blade of residue build up behind the teeth, I am not relishing trying to cut the 9 inch bit ,is there a way of stopping this please or am I just unlucky.

take care

john

A woodworking friend of mine purchased a single large baulk od old pitch pine to make some superb second fix joinery. It looked great but he had real problems with resin build up. I scrounged just enough from him to make a meter cupboard, even then the resin was building on cutters, particularly saw blades, in no time. I decided that it was a price that had to be payed for the brilliant looks of the timber.

Would a form of Teflon/silicone spray on the blade help stopping the resin from sticking to the metal?

Try having a second blade soaking in oven cleaner, if you can put up with the hassle of changing blades - but it may be quicker than trying to clean in situ. If you put any sort of lube on the blade you run a high risk of the blade slipping on the tires and the tires getting oil damage. I now use a chainsaw mill for jobs like this its a great bit of kit.

Resin on a powered saw blade - just put up a scraper to it (old chisel etc) whilst it's running and still warm from use. Only takes a few seconds to remove it.
Sets like concrete if you leave it too long.
PS just to the flat bits behind the teeth that is - in case anybody gets carried away! The bits left between the teeth don't matter so much

don't get silicone/teflon spray anywhere near your workshop. It risks causing all sorts of future issues with finishes adhering to timber.

While sawing spray the blade with turps.

Second that ! I don't know if it was the right thing to do but I had to rescue a bandsaw someone else had used to cut resious pine and the build up on the blade was so bad that it filled up the clearances to the guides and jammed the blade. Turps was my friend. Worked like a champ and very fast.
