LMI Plate Joining Jig for Tops and Backs
why not put the rollers on at the beginnig? you could tension the spring when it is time to bend the sides.
Why don't the company who makes the gramil hone the blade properly in the first place?
Very good
...so, these guys never heard of a dremel and a grinding/cutting disc? That's what i've been using for years with excellent results, never needed a gimmick like this one.
So far, so good with this jig. I mocked up a practice neck out of pinewood as this is my first time. I used my router table to do the truss rod slot and my center finding ruler tells me that that came out perfect. Depth too. I've already done the mortise on a scrap piece of mahogany pressed into the jig, and I've set the neck angle with the jig with the body which is already built. 3.5 mm at the bridge, check. Tomorrow the dovetail tenon on the neck - I've enlisted my 93 year old dad to hold the shop vac hose!
During the switch from the waist blanket to the full blanket, if you reposition the clips to the far ends of the sandwich it will provide better heat transfer during the initial Full bend ramp up.
Steam box....1000 year old better tool
Hi,Robbie. I bought Brace Sander and Radius Dish (15and25)from LMI. I have two questions. Do you use Brace Sander(25radius side) to the upper transverse brace? Do you radius the upper bout or leave flat for tight neck joint? Masahiko.
The Simpson jig !!!!!!!!!!!!!!!!!!!!!!!!!!!!!
'heighth' lol
Regional accent? 😁
I may be mistaken, but didn't the narrator specifically say and repeat that the sanding bars' surfaces are "flat", and not curved to precisely fit the guitars that have radiused fretboard and frets ? Does Luthiers Mercantile offer "radiused sanding blocks" ? I believe that among the guitars I own there is one flat fretboard and three other radius measurements. Accurate and precise radiused metal sanding blocks would be useful. Any helpful responses are welcome, thank you.
These are flat on all sides. They aren't intended to radius a fingerboard. We have radius blocks here for that purpose. www.lmii.com/54-radiusing/s-48/tool_type_or_function-radiusing_fingerboards The bars are good for fret leveling or sanding lengthwise on the fingerboard following the radius. They are also good for prepping material for joining, etc. Hope this helps!
What is the biggest string gauge it can measure? (as in physically fit through)
The tool will clear a 0.230 inch diameter.
@@luthiersmercantileinternat5786 So no problem for bass strings then XD I guess then I will be getting one soon ;)
I can't find this clamp in your store.
Sorry, we no longer carry this clamp although we may revamp and offer it again in the future.
Give me a break. What a waste of time and money. The controller and main board in great but the bending with the use of a ratchet and rollers is ridiculous. If this thing cost more that the controller, it would be a rip off. Not a hope.
i need...
I just used this clamp today on the brace of a really nice Prenkert Classical guitar. It was the angled brace at the bottom of the fan brace, next to the edge of the guitar. I'm lucky to have bought this clamp because now it looks like they're not making it anymore. It is really great, if you can find one!!
We hope eventually to have this clamp again but it's probably a way down the road. I'm glad you got one!
@@luthiersmercantileinternat5786 Me too!! There's nothing better than this clamp for those hard-to-reach loose braces at the edges. It actually was a gift, as well. I bet the tooling to make one of these is quite a job!
Thanks for the great video! What are the thickness and width of the blade used here?
The thickness is 1/16" and the width .200"
@@luthiersmercantileinternat5786 Thank you!
I finally got one of these - it was my birthday present to myself. I wanted one ever since I used it at your shop.
Happy birthday to you Larry and enjoy your gift.
hi, do you sell the bending mold for a concert ukulele?
Not at this point Steve. We hope to in the future, but it probably won't be soon.
Really? I love LMI, but this is like watching someone reinvent the wheel by making it square.
No apologies here. We sell tons of them and most who buy them love them!
Is this my best option for stainless steel frets? I have tang nippers, but I don't want to break them.

Love this jig but cannot find it. does anyone currently make it
Sorry, this is not sold anymore but we have another tool you might want to check out: www.lmii.com/215-bridge-drill-jig
I was gifted a soundboard with the sound hole previously cut out. Do you think I can cut a disk the size of the sound hole to locate the center and accurately cut the rosette? any suggestions?
I think this is probably the best way to do it. Just make sure the plug is snug. Any movement in it resulting in movement of the top could cause an off-center or elliptical rosette channel. Make sure everything is clamped/taped down tight before cutting.
Luthiers Mercantile International Thkx!
Do you still have this? I don't see it on the website.
We don't Lucien. Here is a link to an item that might work for you. www.lmii.com/215-bridge-drill-jig
great jig but just a few Q's 1. will gluing top braces in the radius dish still work after using the sanding jig? 2. will the jig be long enough to do an X-Brace for a dreadnought?
Hey Julian, Yes, you can still glue in the dish supposing the dish is the same radius as the radius you put on the braces. The jig is long enough. You just need a longer sanding stroke. It helps to band saw the braces close to the radius you're looking for before you start sanding or your upper arms will get quite a workout!
a pencil line on the surface that's being sanded will help show you sanding progress
Why not use the HDPE as a template/clamping jig, and go to town with a flush trim bit? It's how I did it before I went to laser cutting.
I see no reason that you couldn't do this. The screws screwing the birch ply to the HDPE are easily removed making this possible.
This is another great tip, now back to work!!!
.096 thousandths is not 3/32's .093 is.
Hi there, how much pressure is typical for securing a small - medium size acoustic guitar? With and without Top. Thanks
Our small pumps pull about 20 Hg which is sufficient to hold a guitar. I'm not really sure how much you could go below that and still be secure.
Strangely they state the file has a safe edge you should place down between the aluminum blocks. The safe edge of course, has no cutting teeth on it. Then later, at 3:54 they say you can extend the life of the file by flipping it over. Some disconnect there.
There are two safe edges, the narrow edges, one on the top and one on the bottom. Then, there are two cutting edges on the wide faces. So, you can spin or flip the file. I hope this makes sense.
@@luthiersmercantileinternat5786 what? that is not what I understood at all. It states that the file only has 1 smooth EDGE.
Hi from the uk, where can i buy the digital string height gauge from, thanks.
Hi Jeffrey, we (LMI) ship internationally. Here is the link: www.lmii.com/products/tools-services/measuring-tools/lmi-digital-depth-gauge
I'm interested in the string height gauge. Will it work for a standard, Fender-style 4-string bass?
Hi there Thanks so much for the great video. One question. With the 20 degree bevel scraping technique that you are using on the hard side in this video would you also use the same technique if the side wood was softer wood such as cypress or in my case Red Mountain Cedar? Or would you choose the chisel side of the blade as it comes and go ahead as you would the top? Thanks Cath
Cath, Glad you enjoyed the video. I would still use the scraping method in this case. It seems to works best on sides for getting a nice straight line. Happy Building!
Thanks for the advice and quick response, Robert! And it's not just THIS video of course. Every video I've watched of yours has been really great and super helpful. cheers and happy new year!
is it the end of the set screw holding the blade in or is the screw pushing a shim to lock the screw in place
The set screw holds the blade.
what are the blade dimensions
It measures 1 1/4" long x .200" wide.
That convex side looks much too flat to fit the upper C bout corners of a violin.
I suspect you are correct Johannes. The blade is approximately 1/4" wide with a small radius. Without a violin at hand it is hard to say.
Does this work on radiused tops or is this for only flat tops.
Chris Herrod thanks so much for the quick reply. I'll save up for the jig:)
muito bom
Robert, could this tool be also used as a "scoring " tool for rosettes. I use a laminate router and an attachment, but I'd like to use this tool to score the outside and inside circles so I can minimize tear out, and have nice clean edges for my rosette. John Bogdanovich does this, but I'm having a hard time trying to find the right tool that would do the scoring. Thanks in advance. - Bruce
Why are you using a waterstone with no water?
The stone is wet, but not soaking. We want you to see what Robbie's doing. You can tell it's a little wet if you look closely, and by the slurry on his hands.
I just returned from a 3 week stay with a luthier in Cologne, Germany where I built a classic guitar. Everything was done by hand, just like Robert O'Brien shows in the video - and the bindings and purflings turned out beautifully! It took time, yes, but it was very good chisel practice!
+Erling Westh Not necessarily great for production but it's a relatively inexpensive way to go if one doesn't own a laminate trimmer, etc. Sounds like a fun excursion!
That's a fucked up way of doing that!
+petemclinc It's tedious for sure but it works for people who don't have a laminate trimmer. This is the way it was done for decades before the advent of motorized tools.
No is not...I prefer the gramill to a screaming laminate trimmer. You have much more control over a gramil and risk of stuff ups is much lower.
I just bought 30 pounds of scrap Delrin plastic. Glue does NOT stick to Delrin either! I also bought an 8"x5"x1" slab of Delrin. I made a version of the Mac Stew brace cauls, & crack repair cauls with the Delrin. Acetyl Delrin is strong, and you cannot glue the cauls to the guitar, no matter how hard you try. The clean off easily, and really work a treat.
+Seth B Great idea Seth! Thanks for sharing.
Super ...It was just what I needed .. But I understand not yet how to milling the same depth on both sides as Guitar body abuts the thickness of your jig + thickness of Neck Joint .. But the neck is against the neck joint. fra Danmark..
Johnny Paulick I think you are referring to setting the depth of cut on the router when cutting the mortise and the setting it again when setting the depth of cut for the tenon. On the mortise side of the jig the body does does not touch the bottom of the template so you depth of the cut will need to be the actual depth of the mortise pocket plus the amount of space between the guitar body and the bottom of the template. On the tenon side of the jig the neck touches the bottom of the template so the depth of cut will be the same as the actual size of the tenon. Hope this helps.
Keep an eye out on our website for our new moto tool base (Dremel, Foredom and Proxxon). It's in R&D now, but should be available by year end.
