help needed for special screws

Post by Christoph.Baudisch »

Hi, when being busy with building up my 53 vb I miss one part - a special screw for tensioning the secondary chain.

I have only one of that and for my knowlege these other screws are normal in that place

It seems that they are not interchangeable.
Unfortunately I did not find that screw at Draganfly parts list.
I would be thankful when somebody could give me the dimensions and a source for buying.
Thanks
Christoph

Many thanks for all for these very fast reactions.
I feel encouraged by that kind of help.
As my VB project came from Denmark and I have to create it
from a number of additional collekted bits, there are surprises.
These screws are known to me from another 52 plunger frame and
I will check the interchangeability again in weekend and report.
Thanks
Christoph
