Jimothey Posted June 22, 2018 Share Posted June 22, 2018 (edited) Because I'm swaying more to playing 5 string instead of 4 I thought I'd convert my '72 ish P bass onto a 5 string I have seen people doing this but keeping the 4 string neck and changing the nut and bridge, but to be honest I don't think I would be able to get on with the tight string spacing so I think I will get a 5 string neck and rout out the neck pocket and change it that way I'm still not 100% sure whether it's going to be a Tele or a Precision I'm leaning more toward a Tele but that could change? But here's the donor bass Edited May 5, 2019 by Jimothey 3 Quote Link to comment Share on other sites More sharing options...

kodiakblair Posted June 23, 2018 Share Posted June 23, 2018 I converted one of my T40s to 5 strings. It wasn't difficult but did mean 16mm string spacing. I kept the original bridge plate,inside size is 83mm. Not being a super fast or too technical a player the spacing was fine. Worked out well I think. 2 Quote Link to comment Share on other sites More sharing options...

Worked out well I think. Did you keep the same neck and just change the nut and change to smaller saddles so you could fit an extra one in? I'm not a fast or technical player either so it might be OK...... And save me some money Edited June 23, 2018 by Jimothey Quote Link to comment Share on other sites More sharing options...
kodiakblair Posted June 23, 2018 Share Posted June 23, 2018 Same neck Jim, swapped the nut for brass instead of the original steel. Changed the saddles for mono saddles,took a file to the sides for more room. Had to forego through body stringing but monos are through body or top loading. Had it strung with La Bella Jamerson flats for 18 month, neck handled it no problem. Quote Link to comment Share on other sites More sharing options...

What is your overall string spacing the smallest I can find is 64mm (16mm spacing) which is only 7mm wider than the bridge I'm going to replace? And the heel of the neck is 64mm so that should just fit without the strings falling over the sides of the neck? Did you shave a couple of mm of each side of the nut (45mm) aswell to get it down to 42mm? Quote Link to comment Share on other sites More sharing options...
kodiakblair Posted June 23, 2018 Share Posted June 23, 2018 Sorry Jim was out and about. 64mm overall. Heel is just under 61mm,been a wee bit shrinkage over the years, so I couldn't go much wider. Nut on this fella was 43.5 so only a little filing was required. Main concern was strings still ran on fretboard and within pickup magnets. They do so happy Scotsman.

I measured my Ibby 5 string and that has 16mm spacings and at the end of the fretboard the string width measured 60mm, so I think it will just be ok Where did you get your nut from? the only 43mm 5 string nut I could find is some crappy plastic adjustable acoustic bass nut Edited June 26, 2018 by Jimothey Quote Link to comment Share on other sites More sharing options...

Keep meaning to try one of those. I bought quite a few different nuts but in the end just went for a 45mm brass and filed a bit off each end. Got one of these in the drawer for the rainy day. https://www.thomann.de/gb/abm_6250_webster_nut_bass.htm Quote Link to comment Share on other sites More sharing options...

I thought they looked a bit cheap and nasty and the fact they are plastic turned me off a bit!?! but it would be much easier as they are already 43mm I might just order one and give it a go and I'm probably going to buy a blank graphite nut and cut the slots myself aswell just to see which works better 1 Quote Link to comment Share on other sites More sharing options...
Jimothey Posted July 2, 2018 Author Share Posted July 2, 2018 Got started today on the conversion First job was to remove the nut, the nut I'm replacing it with is 3mm deeper so I had to pare off the nut slot flat Then I marked out for the 5th tuner...... Then the moment of no going back I drilled the hole for the the 5th tuner..... Tomorrow I'll remove the bridge and fill the holes and get started on changing the pickguard 😀 1 Quote Link to comment Share on other sites More sharing options...
Norris Posted July 2, 2018 Share Posted July 2, 2018 Wouldn't it have been easier to sand 3mm off the nut? 1 Quote Link to comment Share on other sites More sharing options...

Its an adjustable height nut and the grub screw goes almost the full width so I thought it would be easier just paring off a couple of mm off the fretboard, it only took 30 secs with a sharp chisel 😀 2 Quote Link to comment Share on other sites More sharing options...

Jimothey Posted July 5, 2018 Author Share Posted July 5, 2018 Well got started on the pickguard and body today Pickguard has had the first coat on it and has been flattened needs a final coat But the body has had a reaction in places so I'm going to sand it back a bit and respray it before I go home tonight You get the rough idea 😀 Quote Link to comment Share on other sites More sharing options...
funky8884 Posted July 5, 2018 Share Posted July 5, 2018 Well done to all those who have spent the time converting a 4 to a 5, how do you find the B string and neck stability compared to a purpose built 5 ? Quote Link to comment Share on other sites More sharing options...

I'll let you know when I've finished but I can't see how putting one extra string will make that much if a difference to neck stability My Ibby 5 string has a 45mm nut (which is 3mm wider than my P) and the heel is 75mm (which is 11mn wider than the P) the neck thickness are the same and both have a single truss rod 1 Quote Link to comment Share on other sites More sharing options...

When I convert a T40 to 5 strings I put La Bella Jamerson flats on it. 38 year old neck subjected to extra strain of 5 quite high tension strings. Handled it no problem and it stayed like that for over a year. Only changed over to La Bella low tension flats because I got a used set for £28. IMO a good B string depends more on the brand, if it works on a bass tuned BEAD no reason it wont work on BEADG. 1 Quote Link to comment Share on other sites More sharing options...
Jimothey Posted July 6, 2018 Author Share Posted July 6, 2018 I haven't got a clue what's going on first the body reacted (spotting), sanded it back a bit sprayed another coat now its fine Put a final coat on the pickguard now that's reacted (crackled) 🤬 Quote Link to comment Share on other sites More sharing options...
SpondonBassed Posted July 6, 2018 Share Posted July 6, 2018 Airborne contamination perhaps from a kitchen extractor distributing greasy particles? Frustrating. Quote Link to comment Share on other sites More sharing options...

Yes very!! I completely sanded the pickguard back to original and resprayed it and it looks OK now Still need to sand the headstock back to maple as I don't think it would look right colour matched I'm going to l leave them both till Sunday and start getting it all back together ready for the nut and bridge when they turn up 😀 2 Quote Link to comment Share on other sites More sharing options...

Looking at the pic of the headstock it does look like it's not central I'll have to check it when I go back to work tomorrow I reckon it's just an optical illusion (well....I hope it is?!) 🤨 Quote Link to comment Share on other sites More sharing options...
