Trying use a RDM extension (my only decent extension) to convert an old ~400cm mast for use with a 4.7
Don't wanna buy an SDM extension (plus the mast is cut down so wont fit anyway) if I can get away with it, as will end up buying a RDM 400 when money permits and a SDM will be useless surplus
So how do I adapt a RDM extension to a cut down (narrower) SDM mast?
Been trying a compressed foam/gaff tape wrap around extension and also to stay inside mast
The other thing I failed to mention: this mast isn't proper standard SDM, as it has been cut down already (i.e: doubt a SDM extension will fit, prob between SDM and RDm would work)
I don't think wrapping it in anything soft like gaffa tape will do the job. You have to stop the mast deforming where it accepts loads. You have to have a reasonably snug fit and a hard non deforming shim to do it acceptably. Maybe you could find a bit of ally tube that is close to a snug fit in the mast. The fit between the extension and the tube is less critical. Gaffa n bandaids might be ok for that.
