Title: Getting beads off mandrels
Post by: SilverGems89 on March 07, 2010, 09:17:20 PM
so now i've made a number of beads i thought it was time to get some of them off the mandrels, errrrm yeah it seemed like a good idea, but i'll be damned if i can actually get any of them off  :'(
Any tips?

Hold just behind the bead with a pair of pliers, and twist the bead, maybe wrap a damp cloth around it.

If it won't come off, try soaking for a while, if it still won't budge you could pop it in the freezer for an hour or two, the mandrel may contract in the cold.

I clamp them in a bench vice and twist and pull the bead off.

Another trick is to hold the bead wearing a rubber glove. Extra friction  ;D

Change hands and your grip every so often... if that fails abandon them and try again later - they'll come off in the end! 

Or better still, get someone else to try - save your hands for making beads! ;)

I tend to double dip my mandrels. Dip and allow to dry a bit and then redip. You end up with wider holes but the beads do come off a bit easier and you don't mangle as many mandrels. The freezer tip is a good one - havn't tried that ...... yet.

Just been speaking to a beading friend re this topic and she uses a piece of that rubber shelf lining stuff - also used for draining boards -  to hold onto the beads while she removes them from the mandrel - says it gives a much better grip. ( I think I've seen the same stuff on a roll in Poundland).
I normally use a bench vice or molegrips to grab the mandrel but for the bead end this sounds like a good idea.

I've found these (http://cgi.ebay.co.uk/Rolson-Pop-Rivet-Gun-75-Rivets-of-4-size-Hand-Riveter_W0QQitemZ330388255944QQcmdZViewItemQQptZUK_Hand_Tools_Equipment?hash=item4cecacb4c8#ht_1229wt_1198) to be the best things ever for getting stubborn beads off mandrels with very little force required, they are fab and will do up to about a 2.5mm mandrel!  (Other sellers are available btw  ;)  )

(https://i.ibb.co/jwVP6QL/Rivetting.jpg)

You put the stubborn little blighter in as shown in the piccy and squeeze the handles veeeery gently to start with, the gun grips the mandrel, and pushes the bead off.  You should technically put a rubber washer in between the bead and gun to protect it, but I haven't got any at the mo.  A slight word of warning, if the bead is well and truly welded to the metal of the mandrel or the mandrel is bent it can still crack it, so wear safely glasses or wrap a towel around it as you do it, but if it's just a particularly bad case of non-releasing bead release, these can save the day when all else has failed.

Hope that helps.  ;D

I've found this rivet gun on their site. It's page 57 of their downloadable catalogue and is described as a four head rivet gun with 75 rivets, stock no. 44409 for anyone interested.

Yep, that's the bunny Pat.  ;D  Which site are you looking at, I can always change the link in my earlier post if it helps?

I think to start with make sure your bead release is not too watery, never use ones which have a hint of mandrel showing :) Afterwards I then soak them in water for a bit, use a bit of kitchen towel around the bead and pull with a pair of pliers, twisting a little.  I used to use my bench vice but it took too long when you have a lot to take off.  Only used for stubborn ones now.  Also soaking in Cillit Bang when difficult.  I get philosophical about the ones that crack when you take them off - They  'must be' faulty so better they show their weakness then than when you've sold it.

Oops, just found it here (http://www.rolsontools.com/images/catalogue_pdfs/Rolson_Cat_08_(39-65).pdf).  Yep, it's the top one of the 2 shown.  Thanks Pat.  ;D

A bit of bike inner tube will save your fingers.

Impressed with the rivet gun idea - off to the shop...
