Okay the grandkids are gone as of Saturday. We had a great time (about 5 weeks) and not too many things need to be fixed around the house. I can now get back to this build. The rough braces are being glued to the top this week. I'll post a pic when the carving and cleanup is done.
It feels good to be making sawdust again!

Happy building! I am just starting a three week vacation, which is fun, but I will miss the shop.

Re: An EIR Dred in the D45 tradition.....
We talked awhile back about ways to hold/maintain the back and top on center to the rims when gluing them down. I have fussed around trying a few different things that sort of worked. If one is REALLy precise when cutting brace end notches in the rims this is probably not an issue to worry about, however I never seem to get a perfect fit of brace ends to notches, which also place the top or back right on center, and hold it there while I glue them down.
I considered this idea as a super simple way to accomplish the task. Although I have not glued the back on yet, I have it ready with the rims notched, and my little positioning blocks glued in place. I used a singe section of kerfing for each block. With the back brace side up on the bench, and the rims in the mold placed over it and both ends on my center line, I simply glued down 4 of these little blocks right up against the kerfing on either side of the neck and end blocks. Now when the back is set on the rims, there is absolutely no play front to back or side to side and when I glue it down, it will not move out of the centered position.
If it doesn't work, I'll let you all know!!!!
Here are a few pics for those who are words-to-pictures-in-the-mind challenged, as I am!!

Re: An EIR Dred in the D45 tradition.....
Today I got the top braces carved for the most part. I'll do a little sanding and it should be ready to fit to the rims.
I'll post a pic tomorrow if I get it done.

Kevin - is your plan to leave those blocks in there or pull them out after the glue is set?

Re: An EIR Dred in the D45 tradition.....
Darren,
I figured to leave them in. They look like the kerfing, and the back ones won't be seen, the front barely. I hadn't thought about chiseling them off but I guess I could.
Top is braced and fit to the rim. Not the neatest job I've ever done. Braces are 5/16" wide....they look wider in the pics. The top transverse brace is 1/2" wide.
The humidity has been really low the past two days 16% yesterday and low 20's today. The top and back have lost some of their dome so I've put them in my humidifyer tub for a couple of days so they shape back up before I glue them to the rims.

Re: An EIR Dred in the D45 tradition.....
These things happen to all of us right?
My neck block is about 3/32" thicker than the one on the plans I work from. Yesterday when I was measuring and marking the top to inlet the rims for the braces, I knew my block was thicker, and took that into consideration when I placed a mark on the inside of the top where the edge of the block would sit...placing the top in the right position front to back. I cut my notches in the rims, finesed the fit, set the top in place and saw that I had almost 1/8" less overhang of the top at the neck end of the guitar then I should have based on where I KNEW the top should have fit on the rims. So I took the top off and remeasured and realized I had placed my mark based on the thickness of the neck block on the plans!! Sheesh!
So if I was to glue this top on as it is, my sound hole will be about 3/32" farther down the body of the guitar, and my bridge will end up being 3/32" closer to the soundhole.....get the picture?
It may not make any difference visually, in playability or in sound, but it's not according to plan, so..
I'll widen all the notches so I can move the top toward the neck end to the right position, fill in the slop in the slots with some mahogany and all will be as it should be......another lesson learned.....
Measure 10 times, cut once.

Good catch! Heck, any catch BEFORE you glue is a GREAT catch!!

Re: An EIR Dred in the D45 tradition.....
I moved the top up into the correct position tonight and filled in "pretty well" the spaces left in notches for the brace ends.
I was pretty sloppy on this fitting. A couple of my notches are dangerously deep in the sides too. Arg...I'm usually very careful and have a tight fit. I don't see a problem with the binding covering these, but I'll probably want to fill the spaces with some rosewood before I glue the bindings on. Oh well, none of this will show so......
On ward!!!!
