Fitting truss rod query!

Hi guys ... apologies if this a real dumb a*** question. I have just received the materials for my first build. Everything is looking good except that the truss rod has confused me.

What I have is a steel bar 5mm dia and on one end the bar is threaded approximately 24mm and fitted with an adjuster nut and what appears to be some kind of washer 5mm thick which is free to run the length of the the truss rod. On the other end of the rod I have a 10mm by 8mm steel plate attached at right angle to the length of the rod and is approx 4mm thick.

Now I want to fit this rod so that it is adjustable throught the soundhole so my first question is do I make sure that the washer is outside of the neck when fitting and prevent it from moving inside and secondly do I route my channel 5mm wide to accept the rod with a T shape at the nut end to accomodate the steel plate or should I route to to the size of the plate? If it is the latter, how would I prevent the rod from moving around?

I appreciate that this is going to be a very simple thing for most of you but as this is my first build I need to understand fully what I should be doing before I pick up a chisle or plane.

Thank you to anyone who can shed some light on this for me!

PaulF -- If you could tell us what kit you purchased, it would help. Many here are familiar with the specifics of various kits but it's difficult (for me, anyhoo) to picture exactly what you're describing without more info -- or a picture.

If it's a Stewmac rod ("Hotrod") for example, it's different from a Martin rod, and they are both different from a LMII rod, even though their function is similar. Some adjust both relief and tension, while others adjust just tension. So, knowing the kit's origin helps ...

Thanks for the pic uploading help. However I have uploaded some pics to my facebook page and have been trying to attach them from there but as you can see ... not wworking. I am following the [img ] copying the pic url here [/img ] obviously without the extra spaces.

Paul -- here's your picture. This looks to me like something for John Hall or Rick Davis to comment on ---. To me, it looks like a rod that has no directional guidance, so exactly how would you install it? (If I got a rod like this, I'd order a rod from www.LMII.com or www.Stewmac.com and use it instead.

Here's the picture:

Seems like for some reason I can't show you pics from facebook but I can give you a direct link. As soon as I replace the [url] tags with [img] tages it breaks!

Hope this will help.

Yeah ... Facebook doesn't allow outside linking.

On the Mac (I don't know about windows), you can just click hold & drag the photo off the Facebook page onto your desktop and then upload it to a site where it can be shared. I put this in the site where I host my own photos soeveryone could see it and comment.

That's a fairly common old timey style "simple" truss rod. To be effective it should be installed in a channel that has been contoured with a bow in the direction of the back of the neck. A hardwood cap is fabricated that matches the contour. When the cap is glued in place the clamping pressure bends the rod and pre-stresses. These rods need to be very deep in the channel as well. Its very similar to Gibson's old style, The cross "T" deal usually gets captured at the neck joint end, but its possible to reverse the direction so it can be adjusted through the sound hole -- not recommended.

I agree with Bill, spend a few bucks and get a modern rod from LMII or Stewy.

Hi Ken thanks for the info on this rod. Gutted because I just bought it and assumed that it would be modern(ish). Can't deal with the routing a curved channel ... this is my first build and haven't routed a straight channel yet. Also I really want to adjust through the soundhole.

So everyone reccommends Stewmac and LMII which is great but I am in the UK ... so I will need to find someone here. My supplier David Dyke supplies ONE other and I have emailed them to ask if I can change it. Hopefully that will be suitable.

Thanks again

Paul

As Ken said, that is a tension rod as was used in older instruments (particularly Gibsons, I have one in my F5 mandolin kit). There are better designs and both StewMac and LMI sell them (and ship overseas). StewMac does sell the Gibson style

http://www.stewmac.com/shop/Truss_rods/Adjustable_truss_rods/Traditional_Truss_Rod.html?tab=Details#details

but you would be better off to get their Hot Rod or LMI's double acting rod if either will fit your channel. Both LMI and StewMac have instruction for installing their rods and very complete measurements ont their website.

As I recall, we discussed this before and link you provided to Dyke's site indicated to me that he was supplying a Martin style single acting rod (the square tube kind) - IMHO that is a better rod than this one However the tension rod will work and if you decide to use it, I have some pictures of installing it in my mando.

Hi Freeman yeah we did speak about it and to be honest I assumed that the one I got was the double acting rod but my ignorance and inexperience proved it to be a mistake.

They are however changing it for the other type that they supply which is a 5mm rod enclosed in a 10mm aluminium square box. Should be problem solved.

Hopefully as things progress I can post a pic or two showing my progress and hopefully not too many mistakes.

The two type of rods work in completely different fashion. The simple threaded on is installed below the center line of the neck and simply acts like a set of strings "behind" the neck. While the strings are trying to bow the neck forward, the rod tries to balance that and bow it backwards. Both the strings and the rod are putting the neck in compression - just on different sides of the center line.

A single or double acting rod actually bends. The ends are anchored at the nut and heel so their bending force is down, while the center of the rod pushes up on the underside of the fretboard. So while the strings are trying to bow the neck, the rod counters that by pushing back up at the center.

A double acting rod has two more things going for it - since both ends move it has twice the affect of a single acting roc (ie - a small turn of the adjuster has a LOT of affect). Secondly, it can actually force the center of the neck down, adding relief (which is rarely needed, but you never know).

All of them work, but if you have a choice right now I would certain switch to either the Martin style single acting (square tube kind) or the double acting (it will have a rod and a flat bar in parallel).

It is apparent to me that you are avoiding mistakes by thinking these thing through - take your time and everything will work out. And please post some pictures, looking forward to seeing them.
