Newel Pegs
70mm square pine newel base, but the peg newel I saw on Burbridge's site had a 50mm diameter peg. Will only 10mm each side and some adhesive really take the strain of being shoved?
It always takes longer than I thought

Re: Newel Pegs
If you glue and cramp two pieces of softwood together with pva glue and allow it to dry fully you will never manage to separate that joint by force, (try driving a chisel into the joint) the timber will split away first, usually close to the glue but not at the joint, the glued joint becomes stronger than the timber alone.
It has to be a reasonable assumption that the same applies to your newel post.
When gluing timber, (and usually anything else) one very important consideration is to always allow the glue to dry without disturbing the piece in any way.

Re: Newel Pegs
Very true for two pieces in good contact. The question I suppose is how good do I think I'll be digging a round hole into the exact centre of the newel base?
I suspect good, but maybe not quite good enough so I was thinking of using a 2 part adhesive like Dry Flex which has some gap filling properties which PVA doesn't to the same extent.

Re: Newel Pegs
Digging is not really desirable, a 50mm auger bit will do the job, or a sharp spade bit.AlwaysLearning wrote: The question I suppose is how good do I think I'll be digging a round hole into the exact centre of the newel base?

If in doubt, use a polyurethane (expanding/foaming ) glue.

Re: Newel Pegs
A common misconception seems to be that gap filling glues have the same strength as wood. They don't. The strongest joint is always going to be one with a good snug fit, hence AyJay's recommendations. A joint where there is a lot of glue but poor, gappy timber to timber contact will be very weakAlwaysLearning wrote: I was thinking of using a 2 part adhesive like Dry Flex which has some gap filling properties which PVA doesn't to the same extent.

Re: Newel Pegs
Size of the gap is also an issue with joint strength.
Or I cut a couple of slots in the peg and make some wedge tenons. Or perpendicular offset dowels. Haven't made those in quite some time.
