I am slowly working on the tool chest project. I finished cutting my first set of pins and after fitting them I notice I just about blew the half pin at the end! 🙁
I am a bit surprised since I didn’t have to force anything in. Should I remake the pin board and use the “broken” one for other aspects of the project, or will this be fine if I leave it? I would hate to have it brake off later in the project – or worse! after I have it together

Yes, David is right. As you have it assembled like this, put there thin superglue and spray with the accelerator. Then remove top board so the thing closes and the joint glues instantly. You only have to make few shavings on the top of the board because accelerator leaves sort of debris. I’m not guessing, because this happened to me dozen of times 🙂
12 January 2016 at 10:39 am #133848As already mentioned, superglue will do the trick just fine, although I normally use regular PVA in situations like that. I feel like I get a stronger bond.
Drizzle some in from the top and let gravity do it’s work while holding the split open a bit. Add a clamp with only light pressure once it has wicked through, or even just tape, then leave to cure overnight.Joe,
I’m also with George- superglue ain’t gonna get it.

PS After the glue dries,for further test fitting and final glue up place a clamp across the board to insure too much wedge pressure isn’t placed on this pin.- This reply was modified 8 years, 3 months ago by Craig.
I’ve never done that! yeah right. It’s disheartening but it can be fixed. I tend to stay away from super glues but that is just my preferance. I use my normal wood glue like some folks have aready mentioned. Good luck with whatever techneque you deside to use.
29 January 2016 at 9:28 pm #134314What I use for splits is Chair Doctor glue. It’s a really thin PVA glue which will wick into cracks. Then clamp it for a hour or so and your good.
Put me in the PVA choir. I’d _carefully_ reassemble with the too-fat tail (too fat pin?) to get the gap to open up to allow the glue to enter the crack. Blob the glue onto the surface and rub back and forth across the crack to force the glue in. If you can, do it from both faces. Immediately remove the too-fat tail and clamp lightly. You should see the PVA squeeze out.
As step two, I would trim the tail or pin so that this particular tail and pin assemble with zero stress. I’d go to the point of being afraid of leaving a gap. The final assembly will make things swell and I wouldn’t want any pressure on this half pin. It is purely decorative now, which is fine…there are plenty of other tails and pins to make everything strong.

29 January 2016 at 11:15 pm #134318The problem is, I can’t figure out which pin(tail?) is the culprit. The one in the picture fits just fine. I think there is a cumulative effect from another one.
29 January 2016 at 11:16 pm #134319Perhaps the crack was there already, if this was the end of the board it could have come from drying stresses.
One more voice for PVA.

Does anyone use a clamp to support the end pins while first trying new dovetails?
I’m thinking a clamp (or vice for smaller work) would allow you to ‘feel’ resistance without risk of breakage?
I’m new to woodworking, and I’m sure I couldn’t wiggle dovetails apart the way Paul does, without something giving. -
