Above is the Lumopro LP633 Umbrella adapter, lauded by many Including the amazing Photographers David Hobby (Of Strobist fame) and Zach (Dedpxl) Arias. Please note the serated edges of the two plates that adjust the angle of tilt of the umbrella and hotshoe flash when fitted.
If you live in the USA these are readily available and easy to get, Sorted. If you are in the UK or the rest of Europe you rely on a distributor in the Netherlands. Very nice people but ordering the said item either via their website or on the phone is err...Challenging.
Above is a very similar looking adapter shall we say from Neewer. The main difference being the said plates are smooth relying solely on friction to hold the weight of the umbrella. Now if you have a 60" umbrella on three quarters of the way down the shaft after a couple of uses those flat friction plates won't hold the weight and that can be embarrassing as it slips limply down in the middle of a shoot. The good news, these are easy as pie to order from e-bay, Sorted? sort of.....
The answer and the reason for this post is a solution I have used to fix this malady.
Undo the screw and disassemble the unit taking the bolt and washer out of the centre and slide the male and female plates apart. Get a junior hacksaw with a fresh blade and cut random 1mm cuts in the outside faces of the male plate and the inside edges of the female plates. when you re -assemble make sure the tightening screw is on the right side and doesn't clash with the other knobs on the unit. Voila the cuts act like the serated edges of the Lumopro unit and grip is increased ten fold. You are then able to hold your Umbrella and Speedlight securely for a fraction of the price of shipping a Lumopro unit to the UK with all the shipping and taxes.
