Well, tonight I closed a sale on a nice new home custom.cabinet job, rather large job. We build our own cabinet doors at this time with our shaper. The customer asked me to bid out his 8’ tall interior all pine wood doors. He told me that when you go taller then 6’ on the doors the price triples. So he asked me to build them. I know I can pick up cutters for these doors for a few hundred dollars, that can be covered in the bid.

Any advice is great. Thanks

when making tall doors you can have trouble with warping and twisting. I would finger joint small pieces together for the stiles and rails and then do a 1/4” veneer over them . This makes for a very stable strong door with out wood movement problems

i second;a1jim, or you can order from your local “door shop” and just put a mark up on it. those shaper bits are going to be more than a couple hundred dollars; and material for your trial and error period.

i used a1jim s advice when i made the 9 foot doors for my house it worked very well they are 5 years old now and very straight door dude could be right too if you get a good bid from a door shop this will help you make your bid and will also maybe give a door guy the job with your markup on hid work make sure you tell the door shop your reselling these and not to jack you around if they want the work because your willing and able to do the job your self in these lean times they should bend over to make you happy

Thanks for the adv, i will look more ito that. Finger jointing say pine and then veneer both sides with 1/4”. The finished door will be knotty pine.

Would it be fine to use mdf as the core and veneer 1/4” knottt pine on both sides.

Cope and stick bits with dowel joinery would be an okay alternative to full mortise-and-tenons.

There’s a reason the price triples. Big doors are a PITA.

You really have to watch your straight edges and get the twist out. Talk
to the installation carpenter and ask him about the tolerances he
feels are workable for 8’ tall doors. Some guys are more skilled than

MDF for exterior door cores? not sure about that. Make sure you don’t get
in trouble there. MDF can be used in exterior applications, but maybe
not the Home Depot stuff. There are some different grades. I’d try
to use a wood core I think.

Have your say...
