Thread: Planing perfect dados

Thanks for the write up mate, very informative as always.

Thanks Derek

Derek,
thanks for this review - it really should be titled "How to create a good dado with a combination plane"
It has inspired me to dig out the Stanley 13-050 and run some trials during the weekend on creating dados.

Paul, these are not "good" dados. These are perfect dados!

Regards from Perth

Derek

Thanks Derek, very informative as usual.

Regards
Keith

Derek, oh Derek

I must take you to task, there is just NO WAY that those dados can be perfect

they can be neat, they can be clean, they can be uniform, but unless you show them with their [exactly] mating inserts they can't be perfect



it's a definitional thing

Oh no Ian, this is indeed the perfect dado. What you are requesting is the accompanying perfect tenon!

I shall offer that up for inspection in due course.

Derek

Ah Derek,
now you're talking like a machine woodworker. Perfect Tenon into perfect dado?



a hand woodworker on the other hand measures a dado's perfection in relation to its mating tenon.



a dado by itself can only be perfect if it is a trench down which one rolls marbles or ball bearings.

Derek and Ian
I was always taught at high school that nothing can ever be perfect.
That is why, in surveys, I never give more than a nine when asked to score out of ten.

Ian, I have better safe that dado board from the firewood pile, and fit a tenon ... make that tenons ... to it. Absolutely cut with hand tools - that is the whole idea, after all we are hand woodworkers.

But have you rolled any marbles down the trenches ??

perfection could be defined as being "as good as it gets" -- which incidentally is the title of a 1990s movie.


while Derek and I are funning, the underlying point is that even if a dado is slightly skewed or of uneven width, this can be "corrected" if the mating tenon has a complimentary skew or unevenness.

I don't want to hijack you thread Derek but just saw this and couldn't help but post it here. Showman ship....yes, attention to detail excellent, would I go that much trouble....no, but it does deserve a degree of admiration.

Hi Derek,
out of interest, how did you ensure your 2 scribed lines matched the width of your combination planes?
Thanks
