Some resinous softwoods tend to clog…… it’s been well known. Long ago I was taught by an old carpenter to use a plane with a wider mouth or to set the frog well back.
Shaping with a metal spokeshaves? They can be forgiven for clogging if the blade is set generously to hog some meat off in a hurry.
Sometimes the answer to this was a [b]Stanley No: 53 [/b]shave that has the luxury of an adjustable bed that enables the mouth width to be varied; coupled with a slightly skewed blade to vary the depth of cut from one side of the mouth to the other, you have a very adaptable tool to deal with most challenging timbers.
They haven’t been made for decades, but come up regularly second-hand and are worth getting.
