Making some iroko gates for my driveway and have a few questions that I’m hoping someone could answer please. The timber is 70 thick with 23 through mortises which I want to wedge. How wide and deep should the wedges be ? I’ve cut the mortices on the mortice machine ( loads of cuts with a 3/8” chisel ). Are the angles for the wedges cut just with a chisel or do I angle the timber in the machine ? The bottom rail behind the front boards, I’ve redimensioned from the drawing to 180. Does it need to have a haunch in it ? Is cascamite a good adhesive to use on iroko ? Watched some of Olly Bradshaw’s vids which are excellent and his wedges are 8mm which seem a bit small for my design. Not sure if I’ve messed up regarding the weight of this project as it will be extremely heavy. The boards are 20mm thick. Any thoughts ? A88EF64D-A0F4-4AD5-8A9F-A5D629E30ACD.jpeg

I'm guessing the mortices are 23mm. so the wedges are best a hair under 23mm.
I make space for the wedge by morticing say 3mm over then operating the handwheel while plunging maybe sensible to angle the mortices with a chisel though the above would work on softwood.the weight is the weight make everything HEAVY DUTY! Good luck

Thanks Johnyb, especially your encouragement on the weight issue ! I tried the hand wheel technique and gave up, too messy. 3mm is a skinny wedge, perhaps 8mm is ok then ?

You should be cutting down in small steps and moving the wheel towards centre of mortiise. You'll get the hang of it after you done a few hundred :)

you could try to angle the wood on the mortiser using a wedge then turn it around for the other side. the gap is really so the wedge doesn't snap because it's to thin. I find pu glue good on the wedges as it's slippy( but messy)
I brought some big hinges from a car boot made by Charles collinge.they still make em v heavy duty v PRICEY!

Thanks, I’ve cut them square now and will add the angles with a chisel and guide block. Bit time consuming, but accurate and controllable. Olly Bradshaw uses the pu glue, but the limited open time scares me ! For the wedges, no problem. I’ll check out the hinges, thanks.
