Help!

I was rebuilding a control stick on a radio transmitter and need to get some ball bearings to replace those that are missing - ( ...long story but the aftermarth involved unsuccessfully crawling over the floor with a torch, a magnet and sticky tape)

Not sure exactly how to measure the little blighters as they are increibly small - > 1mm I think.

Can anybody point me in the direction of a supplier. I think all I can do is buy a few sizes starting at 1mm or so getting smaller and see which ones fit.

Thanks in advance for any pointers

Regards
Jonathan

Make / model of Tx?

Hi Martin

TX Graupner MC32

New sticks are £80-120 and factory fit only!

I think my "missing balls" are 0.8mm so will see if I can locate a supplier.

Having just googled lots - I have found 100 for £70 but also realise that they may be the size of the balls in some Biro's so maybe there is a readily available source - just need to find some Latex gloves:)

try Simply Bearings www.SimplyBearings.co.uk
I have had loose steel balls from this company.

David,

Thank you for the link - I had found this company on the net = 10 x 0.8mm ball bearings £12 - that's £1.20 each for something about the size of a grain of salt:) but certainly cheaper than a replacement module.

I may resort to this option - for now I am intending to carry out "open heart surgery" on 20 Bic Biro's. Also wondering what else I have in my den (old CD player etc ) that may have some of these little guys hiding in...

Also scheming to use the hoover with an old pillow case or similar across the suction end and see if I can find the absentees

Regards
Jonathan

Hi, I was at Warwick yesterday, and saw packets of ball bearings for sale on Tony Green Steam models stall. I only remember they went down to minute, (smaller than 1 mm) . BUT, they may only be available in imperial sizes? As per a lot of steam fittings?
Www.tonygreensteammodels.co.uk   - no connection, just a suggestion.

Chris,

Thank you for the info - I had a look today the smallest they had where 1/16th I think 0.8mm is more in the direction of 1/32nd

They cleaned up really well - just got to fit them now!

To give an idea of scale this is them sitting on the rim of a 1p coin
