Hello all,
I have been using the Dubro flat hinges and wanted to give the 1/8 inch robart hinge a try. I bought the hinges and centering tool. I went to install them today and after putting my marks on the control feathers I saw that there isn't enough wood to really grab into. Let me explain. The average depth of wood that I would drill into was only 1/2" and since the hinges are approx 1" long I would loose most of the grip since the barbs are at the bottom 1/2" and after enlarging the hole to accomadate for the taper next to the pin I can't see much holding power. I am under the assumption that you must have to put extra blocking behind the hinge locations. If so I didn't realize this till to late. Am I correct in assuming this? At least I'll know for the next time. Thanks in advance for your help.

Regards,

Pat

The Robart website recommends installing backer blocks to get full-depth bonding, as you suspected, Pat:
