« Part 30: PTLT I was ready to post as finished !! Part 31 of Working with recycled timber series Part 32: PTLT fixed section and hinge rework »

I purchased a second set of Concealed Hinge Blind Corner 95 Degree to do hinge rework on.
Firstly the hinges are only designed for 19mm timber in their present form.
This deduced from a graphic on the template and my prototype evaluation.
However you can use them on timber larger if you wish.

Here is how I used them on 38mm timber

Simply a matter of recessing them

This is only a prototype to enable me to complete my PTLT top with no opening gap when closed

It appears that the hinges should have the mounting plate as the fixed section and the 35 mm hinge section as the pivoting door/top

I think unless somebody else knows otherwise its purely a cosmetic result

Here is the hinge pivoted in both aspects

I also found the template for the instalation left a lot to be desired, in particular no defined center lines were marked on the template, and info there was misleading.
Hinge drilling the center line for the 35mm hole does not extent to the edge of the template

The 21.5mm line on the mounting plate is not centralised on the 32mm line and the the large arrow at the top near the 5mm hole (B) is 3mm too low.
The second large arrow below the 21.5mm offset line is 5mm too high for the bottom hole!

If you use the 21.5mm off set arrow thinking its the center it miss aligns the 5mm Mounting plate holes

The 21.5mm off set arrow is actually 3mm above the 16mm center line!

This is where the true centerline is.

A call to the distributor of the product was made and the sales rep I spoke to took it all on board and agreed it could be laid out clearer by extending center lines to the edge of the template in both cases.

He indicated it would be corrected at the next print run. (Stand By)
Meanwhile if you use the hinges draw your own center lines on first before starting work!!

Just goes to show some times its worth the explantion.

Any way back to the PTLT top

Here is the prototype next to the table

And in its open position

We now have the correct 95 degrees opening this time.

Conclusion:

Looks like the existing table top will be removed, a new one redesigned from the prototype and refitted and re Varnished and stained…soon.

Great solution. These Euro hinges are great. I have been using them on cabinets for many years, but I haven’t thought to use them for an application like you have here. Well done Robert.

Thanks for the blog.
