Re: Bolt on bolt off neck - order of operations

Hi Trevor Thanks for the reply. Yes, I misinterpreted the paragraph about yaw and pitch adjustment. I fixed the yaw only. I guess the plan indicates that the neck is completely square and it shows the position of the mortise relative tho the square tenon - and I still cant quite picture how the bolt...

Re: Bolt on bolt off neck - order of operations

First a couple of principles to remember: 1) In this style of construction, the neck is set co-planar with the upper bout. So no gaps between a straight edge placed on the neck blank (no fret board) and the upper bout 2) The projection of a straight edge over the upper bout should clear the saddle ...

Re: Starting out on J45

Hi All. Well, I'm the proud owner of a square 3/8 inch hole. All has turned out well. I visited a friend with some heavy equipment. Of course, the collars supplied with the mortise kit didn't fit either drill press he had so turned up some that did fit one of them. Then he gave me the drill press :c...

Re: Starting out on J45

and..yes, the hand chiselling route may have been the quicker option. I have a mortise chisel that would have done. In fact, I imagine only the one face needs to be flat so could have ground the brass bar to a D shape to fit.

Re: Starting out on J45

Thanks for the replies. Yes, just found the video. I wish mine worked like that. I have sharpened as best I can and honed the outside of the chisel to a mirror. Its set up correctly and I have got it to work after a fashion (cut a small square hole in pine) but it will break my drill press if I heav...

Re: Starting out on J45

Hi Trevor OK, thanks, I'll have another look at it...at least I don't need a heavy-duty drill press. The drill bit makes a small hole and the 4 points of the chisel make dents and that is it. The drill press is a bench mounted one and not even bolted down so I can't exert a huge amount of force, but...

Re: Starting out on J45

Hi again well, I have invested in the 3/8 Carbatec mortise chisel to add to the Carbatec set. I've just installed it on my rather undersized but faithful old Ryobi drill press that has seen much action over the years. I can't get it to do much more than make a small dimple in some soft pine. So, I'm...

Re: Starting out on J45

Hi again. I recently finally got a Carbatec mortise kit to do the neck mortise. It came with a 1/2 and 1/4 inch mortise bit (I'd asked for 3/8). How critical is that square hole - is a 1/2 inch hole too big? I suspect it'll be easier to find 3/8 brass bar (have yet to look) but just wondered how cri...

Re: Further J45 questions

Great explanation Trevor, thanks very much. When the Stumac bit arrives, I'll check the depth with the collar on (didnt know about the other brand). I hadn’t thought about the 'doughnut' Several folk have mentioned shellac. I have golden shellac flakes but I've used bullseye (I think) shellac on a h...

Re: Further J45 questions

Hi Martin thanks for the tips - maybe cutting the purfling first is the way to go then. I've just ordered a Stumac bit so it better be good for the price!! I've also decided to make a modified version of the GG system in the end as I have found a track that slides up and down freely that I can attac...

Re: Further J45 questions

I suppose, if you use a spacer to increase the gap between the cutter and bearing, that'd work but it is a very specific cutter. I guess the point of doing the binding first is there is possibly less possiblity of tearout of the soundboard...is that right?

Re: Further J45 questions

Hi again. I've been looking at options for routing the bindings but since I'm following the book religiously, figure I'll adopt the method described with the modification that I have an old linear track I can use as the raising and lowering bearing. One thing puzzles me though. The book indicates ro...

Re: Routing bindings/purflings

Thanks again for the feedback. The overhead router approach looks similar to the Gilet Gore approach. If you use that with a bearing, doesn't that mean you have to do one pass to the bearing/cutter depth? So does that increae the chance of splitting bits out...how do you approach the process to mini...

Re: Routing bindings/purflings

Thanks guys. That is quite similar to the one I made for my makita laminate trimmer. As you say it doesn't have a soft start which is a bit scary. I found the whole process of holding the thing against the side of the guitar quite a nerve wracking experience so was hoping to find another approach le...

Routing bindings/purflings

Hi Folks, I'm after a bit of advice as usual please...I'm at the point where I need to do the bindings on my J45. Last time I made a guitar, I made a hand-held jig which followed the side contour of the guitar, which was a rather stressful approach and didn't give perfect results. I'd like to make i...

Re: Bolt on bolt off neck - order of operations

Actually, I've answerd my own question and notched them both out. It's quite a challenge to get everything perfectly aligned, perfectly mating with the headblock and so-on. But I think I have achieved a reasonable fit so I'm going to bed happy. Hope it fits on as well once the back is glued on! Chee...

Re: Bolt on bolt off neck - order of operations

Just about to notch the side linings to take the upper transverse brace. I can't see it covered in the book, but on the J45, it appears that the upper cross brace is also notched into the linings, is that correct? They end up quite close and of a similar depth to the transverse brace notch so do you...

Re: Bolt on bolt off neck - order of operations

Thanks Col, I'll bear the Stewmac calculator in mind. I have a pre-cut fretboard for this build so can use that as a guide for nut position etc. I just wondered if I had missed something as the book gives specifics for the 12 fret options but not the 14. Cheers

Re: Bolt on bolt off neck - order of operations

Hi again Trevor Before launching into cutting the neck , I was looking at fig 5-2 which gives the neck layout for a 12 fret build. For the J45, it'll need to be longer won't it. The calculation for the head side of the nut to body is explained but I can't see the basic dimensions required for a J45 ...
