Linkon SD10 - front legs have different angels

[Ken Byng]

David Hartley is correct, the problem is on the changer endplate. It would appear to be a case of someone forcing a double thread in the soft aluminium endplate as a result of carelessly installing the leg at some point. You could get someone to drill out the defective thread (at the correct angle), and fitting a helicoil into the leg socket (again at the correct angle). Either that or get Wayne Link to make you a new endplate. I have a helicoil fitted to my Sho~Bud and it sorted out a stripped thread on one of its leg sockets. An engineer mate of Dave Wheelhouse fitted the new helicoil for me. Mine was as a result of buying a new set of stainless steel legs from someone in the USA, one of which had a tiny burr on the leg thread. It stripped out the existing thread in a flash.

I still think it is the result of a leg being forced in at the wrong angle and cross threaded and i stil think the best soloution is to run the correct tap through it at the correct angle you have nothing to lose and it could be all you need to clean it up.
If as I suspect it is a standard half inch 13 tpi, I can send you the tap if you promise to return it.

Those things often happen in an instant !
John Davis suggested to clean up the thread with a tap.
I think i will try this first, and then go on to drilling a hole in the right angle, putting in a threaded insert.

Thank you for your kind offer !
I am going to buy that tap, i guess its a good thing to have it in my collection .
your are right about the thread dimensions, measured it today.

the leg endings are all flush with the plane of the socket, i think that contradicts the cross thread theory.
but what do i know.
i will clean it up first, cant hurt.
if i doesnt help, i willl have to drill and put an threaded insert into the socket.

some new photos, where you can see, that the rear leg in changer endplate is also affected.

I have in the past overcome a similar problem with a different solution......I purchased a 10 string plank that was a "home made " job and the 4 legs were loosely screwed into the bottom of it so there was no splay angle at all and it was totally unstable so, in desperation I searched the net and found some steel pressings at the right angle about 17.5 degrees but they only had a threaded hole in them about 8mm so i drilled them out to half inch clearance and welded half inch nuts into them problem solved steady as a rock, not pretty but not too shabby either.

As long as the playability of the steel is not compromised, a bit of leg mis-alignment is not something to be concerned about, in my opinion.

It's how the thing sounds, not how it looks
