<p>I don't know, Ned - that could have been a "tone burrito" not making any noise until about 45 minutes after it's consumed....:)</p>

<p>Edit: Mario Proulx's web site has pictures of his setup. Self explanatory and a lot of good ideas. That's true of the rest of the site, too. Here's the page with the glue setup, lower right corner:</p>

<p>This is from a long ago memory so I may have some details incorrect.</p>
<p>Canadian Luthier Mario Proulx uses squeeze bottles with a nozzle (like some ACC bottles) filled with dry HG. When he needs to use one he heats the bottle in the microwave or a hot bath and then uses the applicator tip to direct it to where he wants it to go. When he's done he lets the bottle cool and it's ready for the next time. No glue pot, no decomposition, no problem.</p>

<p>I'd think that a better question is; Would it impact the burrito if your business partner left a three day old cup of glue in the microwave? </p>
<p>Or how about; Would it impact the bridge glue joint if we mixed a three day old burrito and a cup of glue in the microwave?</p>

<p>We keep our HHG in a pot all day long but I like the microwave idea and also like the idea of never having to worry about forgetting to pull the plug on the pot when I am half way home....</p>

<p>Thanks for some great ideas Frank! Does it impact the glue heat if your business partner left a three day old burrito in the microwave.... ;)</p>

<p>Well, I do tend to be fearless when it comes to clamping bridges. This is my go-to clamp for use with the StewMac caul setup, and the smallest clamp I'd use with it:</p>

<p>The literature for hide glue suggests pressure in the neighborhood of 100 lbs/sq. in., so that means we can put better than 500 lbs. load on a bridge/top joint without any fear of "starving" by squeezing out all the glue.</p> Thank you very much for the i…tag:fretsnet.ning.com,2014-05-16:2177249:Comment:1328122014-05-16T20:52:11.324ZJon Burtonhttp://fretsnet.ning.com/profile/JonBurton
<p>Thank you very much for the input Frank! A different perspective on the problem...</p>
<p></p>
<p>So,you reckon with the bridge heated in the microwave I'd have enough time before the glue gelled to clamp the bridge down (I could do it in just under 60 seconds. Maybe faster, with practise!)? It's certainly encouraging to know hide glue is more forgiving than would be expected.</p>

<p>I'll have to look into the clamping side of things. I do have a feeling that this stewmac caul doesn't put as much pressure as would be desireable on the back of this bridge (but then, it is a one-size-fits-all caul...). A G clamp (or three) with a deep throat and a caul made to fit the bridge may be a better option. Cranking the clamp down hard does frighten me a bit though, I have to say...</p>
<p></p>
<p>Anyway, the bridge has been sanded to conform to the top profile, as per Hesh's tutorial. I'm going to sleep on it (it's night time in my part of the world) and decide on a course of action tomorrow. There's been a lot of advice offered here and I'm really grateful for everybody for their take on the problem.</p>
