Tenoning and consistency of measurements

[engineer one]

i also think mr grimsdale is right, if you have been properly taught to use
a rod, but many of us haven't and i personally have found them quite
confusing to use.

i know it takes time and patience and i will try to learn how to do it,
but not this week

so i suggest a jig which ensures that each second tenon starts in the
same place.

Of course I had to do a drawing for you.

Just need the 'ratters to confirm whether their techniques require the material to be exactly the same length or not :wink:

You can do an exact equivalent of Dave R's jig on the rat - make yourself a horizontal table (if you don't have one already, its just a piece of 18mm screwed to the top of two bits of 2by which are held in the clamps), and put a stop on that (I just insert a screw until the head is a couple of mm above the surface) against which you place the already cut tenon shoulder. Move the table until the other shoulder will be in the right place, then leave it alone.

The material can then be any old length

Glad to be of service.

ok dave, you have taken the story and drawn the item,
so can you know help me learn how to use sketch up like that please???

paul :wink:

 

[SketchUp Guru]

Sure Paul. If you haven't done so, take a look through the design forum for my babbling about SketchUp. Get started drawing and get familiar with the tools. Then feel free to ask any questions.

FWIW, I'll be away from a computer from tomorrow through Sunday so I won't be able to answer SU questions until my return.

Not sure how I missed this thread first time round, but having been musing over how to cut the tenons on a slatted shelf ( American White Oak front and back, with 20 slats M&T'd into them front and back) all is now clear. Many thanks everyone for your suggestions.

gosh darn does that mean we have actually
sorted a problem, and given someone a new idea or two??? :lol: :lol: :lol: \/

how are we going to go forward now if we actually achieve
something

paul :wink:

Paul, it looks like we're slipping up. Quick! someone come up with a new one so we can bury this thread.
