....But before that I need to tidy up the mess I made of the heel and see if I can patch it up with a block of maple (completely new ground for me). May resort to something else if that proves too difficult. The good thing is that it will be hidden so just needs to be tidy and structurally sound.

Feeling better about this now.

If you neaten up that hole into a nice rectangle and give me the dimensions I make you up a maple filler block and post it down to you. :)

Just a thought - now you have the t/r out, couldn't you just get someone to weld the snapped bit back together? :)

Hee hee. It's what we in the South West used to call a Bristol Screwdriver.

Wow. That's very kind of you. Woodworking is not a strong point for me. I am way better at making holes than things to go in holes. I will give you some numbers once I am happy with the hole..

Problem is that the thread is snapped inside the first collar. I suspect it would be too hard to weld.

Anyone bought from these Slovakian guys? They are the only supplier of MM type (capstan nut) rods I can find.

The allen key type are no good cos there there isnt enough space at the heel end to get an allen key in.

I've not... but their prices do seem very competitive (not looked at their shipping costs yet) so I think I might check out the quality of some of their bits and bobs in the near future.

The one from Stewmac I mentioned earlier can be found [url="http://www.stewmac.com/shop/Truss_rods/Adjustable_truss_rods/Hot_Rod_Truss_Rods/Spoke_Nut_Hot_Rod.html"]here[/url]. They are a little dearer but the quality is top notch and the double sleeving means they are less likely to rattle. These Hot Rods do need a relatively deeper recess to sit in so check your dimensions throughly first - you need it to be tight as a gnats.

The Stew Mac one is way too big unfortunately and it seems the old rod left it's wrapping inside the neck (presumably it's stuck to the neck). The Slovak on is exactly the same dimensions so I was thinking I might try and install it without it's wrapping. Hopefully it will drift in OK.

BTW. Dimensions are on their way.

It might be worth trying to remove the wrapping with a coat hanger or similar. I use wood screw on the end of a long rod to remove cleaning swabs stuck to wind instrument bores, gently push it up until you feel the obstruction then slowly twist, the swab (or wrapping in your case) starts to tangle on the screw, then slowly pull it out , hopefully with said obstruction still attached.

Hi. Appears that the right length rod may be difficult to source. Now wondering what would happen if put one in that is slightly too short (e.g. 20mm). Looks like the old one only just makes it past the first fret anyway (remembering it goes in from the heel end).

Wondering if to get this, reduce it to the right length (by removing about 50mm off the blunt end) and then get it re-welded.

I have a vague memory (from a misspent education in engineering) of some treated steel being difficult to weld.

Am i getting desperate or is this a sensible approach?

Well. Looks like the old girl will soon be back in play soon... Yay!

The truss rod is a double bar single action type with a capstan nut (just like a real Stingray I guess). Couldn't find a replacement rod the right length so bought one that was too long from Ebay, removed the wrapping (because the old wrapping was left behind inside glued to the neck) cut the end off to get the right length and got a local welder to re-weld the new ends together. I had to do a bit of fettling of the weld end 'cos it was a bit of a lump (didn't explain properly what I wanted) but managed to reduce it back to the size of the bar and with a bit of a taper so it wouldn't snag on the wrapping in the neck on the way back in. Managed to drive it all the way back in by holding the neck upright with the lubricated rod in a few inches and pointing down (with the capstan nut on the end) and dropping the neck gently and repeatedly (rod first) on a carpeted floor. Took about half an hour to get it all the way in. Lubricated the nut and tightened it up carefully to see if I could straighten the neck and it works (yes!). Now all I need to do is patch the hole I made in the back of the heel (with a piece of maple on it's way from the very helpful Ou7shined) and put it all back together.

Very pleased with myself.
