source for spare parts I always loose on the floor and can't find :)

Better solution is to super glue spacer and nut to frame so they would not get lost in the first place.

Um, the nuts and washer/spacer parts are plastic. 

Doh!  Then the towel will help.

no . but when I do it's at a bad time

You can get them from Atlas and or Kato. The plastic nuts and spacers are the same.
By the time you find a source for them you will find out that you will have to buy 100 or more.
Get a dozen or so from each and put them in your spare parts bin.
Be cheaper in the long run.
I always have more than 6 nuts, screws and spacers on hand. I very seldom lose one but once in a while one will hit the floor and I will not find it for a day or so, I just grab a spare and move along. I most of the time will find the lost part on the floor when I do a clean up!

Here we go (for Kato):
900040 Screw 2x7mm, Round Head, 6 ea $1.20
901010 Hex Nut, 2mm, 6 ea $1.00
902010 Insulating Bushing, 2mm, 6 ea $1.00

   

For those prices you can buy 4 packages of each and have 24 of each.  But I would still wear my watchmaker's apron when working on my models.

For non-ferrous parts you can use a fine knit cloth (old dress shirt) on the end of a vacuum tube or larger floor vacuum attachment head.  An apron does not really help for parts that are flung off a wire or spit out of the jaws of tweezers or pliers.

Those are the ones that make me angry...

WHYYYYYYYYYYYyyyyyyyYYYYyyyyyyyy??????

Yes, so-much-stuff sells on US eBay too, and they have lots of useful goodies, but in some instances (especially some of the trucks) they prices are a bit inflated.

I use some scrap pieces of pantyhose (not mine!  ).  Allows for better air flow.

I put an old white sheet on the floor under my workbench and chair, everything I drop ends up on the sheet and is easily recovered. When the sheet gets too dirty I pull it up and wash it. I had to do this because the carpet in my workshop is shag and anything dropped in a shag rug is lost forever. That sheet and the apron mentioned earlier will help a lot.
