• Do you mean because of tolerance, or because of stock thicknesses being different? Both come in 18mm but I understand I'll need to do a little refining of tolerances in prototyping. Luckily the Valchromat will be used for most of the tenons and has a higher tollerance.

    @pryally that looks awesome, I like those dowels as a feature actually.

  • Yeah more what pryally said. The 18mm is just a nominal dimension. You'll find it varies between 17 and 19 (or thereabouts) between batches. So cutting a groove might work with your MDF prototype but that may then be loose when you build it with ply, for example.
