I have read this and understand but I am having a slightly differnt problem of late. I am supergluing the bolt to the disc but when I go through the body to tighten the loc nut, the entire superglued disc turns, which means I cannot tighten the loc nut. What am I doing wrong it is so frustrating. I thought I could use a regular nut and super glue that when I've finished but surely there is something I am not doing right.
I used to have this problem as well - the way I got around it was to either use a cotterpin for the head only (you can buy bags of just the pins - I got some from ebay a few years ago and I'm sure you still can). A cotterpin doesn't require you to hold onto the other end so it means you can close up the head and finish it off entirely before joining to the body.
Or, something I do now regardless of the head joint I use, is actually leave an opening at the back of the head where the gusset joins with the side head piece, just as you would with the back of the body seam. It closes up nicely later on but lets you joint the head to the body before stuffing so you can get a spanner or socket in there to hold the other end :)
Neither of these methods will likely be of any use to you now, so maybe try the regular nut and hold the end of the bolt with pliers to enable you to tighten the bolt down. Then add superglue as you suggested.
I also use the grub screw or set screw for all my joints.
Now for your glued disc....Are you holding the disc itself while you are tightening the nut? That is how I did it before I discovered the grub screw. If the glue is not holding there is nothing you can do but take it out and start over.
I have a hard time getting the joints tight with a cotter pin too - I hear cotter keys are good for getting them nice and tight but I don't have one. Never used grub screws because I don't understand how it would make a difference to the issue, clearly there's something I'm not getting! Leaving a gap in the head is usually how I get around it now anyway - and leave it until last to stitch it closed so I can reshape the head if I need to after nose and eyes are all finished.
Haha, actually... I just googled grub screws - I wasn't picturing them properly and didn't realise you could hold it still with an allen/key while turning the nut. D'oh!
I have a cotter pin key, but I don't use it. I use a pair of needle nose pliers and I roll it down tightly. You can really tighten it up better without the key. The trick is to roll it straight down, not letting the pin open up. Keep both rolls very close together sitting on the washer.
If I use cotter pins, I use needle nose pliers, it gets much tighter than the key turner, but it does take practice.
For nut and bolt ones, I glue the bolt to the washer, make sure that's totally dry before I glue it to the disc, then hold onto the disc as I add the nuts. I don't use locking nuts for this joint, I just use 2 ordinary nuts as there's far less pressure on the glue at that point.
Wow! I came here tonight to ask about tight/not so tight joints & immediately got my answer...I think. I've been getting some tight enough, but some very loose & tho' I thought I was doing everything identical, apparently I'm not. The bear I just finished has very loose legs yet her head & arms are fine...? I got my husband to tighten the leg joints because he has strong hands. Or at least that was my thinking. Perhaps I should have done all five joints myself? I'm using hardboard disks & cotter pins & I also use needle nose pliers. I sure would appreciate any other tips you can give me to assure a good tight joint?
Thanks in advance
