Re: water based finish over linseed oil

I switched to Pure TUNG oil on light wood. Over the years I have used figured Maple a lot and want oil for initial wash coat. Even driers will tint it brown. Dilute it and give it several days to dry. It is the best of naturally drying oils due to molecular structure. I have had old linseed oils re...

Re: Outdoor glue for deck railings

I used gorilla glue with W.R.cedar for an arched arbor at my previous house. Scarf joints all over it. It held up perfectly for at least 8 years of New England sun, rain, snow and wind. Then we moved so I don't know what's happened to it since.

Re: Glue for colored veneer marquetry in spruce top

Shrinkage! (Apologies - irresistible Seinfeld reference.) I'm definitely not good at inlays and rosettes so ... grain of salt and all that ... but if you want to know how things can go wrong ask somebody who makes lots of mistakes. I did something like that with pieces of very thin burl veneer using...

Re: water based finish over linseed oil

Hi Alain, I know it gets darker and eventually quite dark. The very old examples I've seen didn't appear yellow to me but perhaps because they were on dark wood or maybe because they were so old they went beyond yellow.

Re: water based finish over linseed oil

Thanks Clay. Don't know why I didn't think of using a shellac barrier coat but that would be wise. As for waiting 2 weeks ... one of my motivations for using EM6000 was speed. It takes me a month to french polish a whole guitar but I can fp just the top in about a week, getting in 3 sessions each da...

Re: water based finish over linseed oil

On the other hand, they say it can be used over oil-based grain fillers and they sell a tung oil based sealer for use with it. However, I think you all are right - plain linseed oil sounds like a bad idea. I'm turning to shellac in some form - probably just keep going with the french polish and pumi...

water based finish over linseed oil

Does anyone know if oil under EM6000 is a bad idea? I am just finishing a walnut/engelmann OM. I'm french polishing the top but I want to use a water based lacquer for the rest. I think a coat of linseed oil would enhance the walnut tremendously so I'm wondering if it's safe to put a product like Ta...

Re: Bolt on issues

I forgot to mention that I also tried threading cut-off & sharpened bolts into the threaded inserts in the heel and using them to mark the block, as Alan described. That probably worked as well as anything I've tried, or it would have if I'd drilled at the right angle. Having the centerpoints is hal...

Re: Bolt on issues

Thanks Bob, I sorta follow what you are describing. What I have done it pretty simplistic - I roughly fit the neck while the back is still off, mark and drill the holes in the tenon using the holes in the neck block. I can only get my drill into the bottom hole, the top one I have to mark, take the...

Re: Bolt on issues

... I keep thinking I should make a jig for drilling neck inserts - maybe something like a dovetail jig that would index both the body and neck. Anyone made one of these? Well, I've tried it twice. The first time I based my jig on one in the Gore/Gilet "Build" book. I differed from their build by u...

Re: Neck Block Buttress, but How?

Barry Daniels wrote:Bob, this is an open forum and you are always welcome to post in any thread.

The buttress is strictly structural to prevent rotation of the head block and the need for a neck reset. But they are not common and have not been around long enough to judge their long term effectiveness.
Thanks Barry!

Re: Neck Block Buttress, but How?

Please forgive my butting in on this thread with an off topic (but related) question. And forgive my ignorance too. I'm a noobie. :^) What exactly do the buttresses do for the guitar? Are they there exclusively for structural support? It looks like they would prevent the top from sinking above the s...

Re: Double sides

I've vacuum veneered 1 set of laminated sides. Cherry, .045", maple .045", cherry .045". The layers were stacked and pre-bent on a Fox-style bender with a blanket. Gorilla polyurethane glue. In my first attempt I spread the glue and stacked the layers in a 6" wide bag clamped at both ends, laid over...

Viewing Photobucket-disabled pictures

Hi, I'm not really new here but I have not been visiting a lot recently. Now that I've returned I find I can't view pictures that folks have posted. Instead of a photo I see an icon from Photobucket with some text saying I (or maybe the original poster?) should update preferences to enable offsite h...
