NEW Good BU Plane such as Quangsheng 62 is Miles and miles better than a standard old-school plane, you need to have a real expertise to setup a regular old battered vintage plane to shave as smooth as the BU will do almost right out of the box..
I would rather use the hours needed to turn an old plane in to good plane in actually making something... + Again..People new to woodworking will have a rubbish experience with one of the old planes as they don't really know what they are doing + it's hard to actually learn without knowing what you should be getting.
A good 62 plane starts from 100-140pounds , a decent shape 5 1/2 will run you 40 ,sure you can tune up both to give same results but for me it took like half a year and number of days to actually ''learn'' how to do it properly and get the results I want & I still don't think I'm expert in it
In actual billable hours It probably took me like 70-80 hours in research/trying out various things/learning the ways to sharpen it/shape it / etc... so even at minimum wage that's like 500pound investment just to get it working.. There's no way I'm getting that back..
I wish I had bought a new 62 plane right away...
All the old farts who have never actually tried a modern good 62 plane, please just don't comment nonsense...
Btw, I funded my Good tools by purchasing cheap old planes from ebay, fixing/polishing them up and selling for 3-5x more.. I have gone through at least 25 of the older stanley/records, not 1 plane I received was in the state of ''use it out of the box for smooth results'' ,a newcomer will simply have no idea what's wrong with an used plane and what needs doing to it to get it perfect- again they don't even know what results you should be getting from a good one as they have nothing to compare against..
Yes it's a cheap way to get in to woodworking.. but it's a waste of your time..
