ScottR Posted April 27, 2018 Report Share Posted April 27, 2018 The metal has a very cool look to it as is. I don't suppose that is going to last though, is it? SR Quote Link to comment Share on other sites More sharing options...
FINEFUZZ Posted April 27, 2018 Author Report Share Posted April 27, 2018 No, the existing surface finish won't remain. There will need to be considerable grinding, filing, sanding on all surfaces. You can see oxidation forming from my fingerprints I left on it yesterday, and without treating the surface, it would quickly dull. Quote Link to comment Share on other sites More sharing options...
Splintazert Posted April 27, 2018 Report Share Posted April 27, 2018 Looks good FineFuzz! I'm wondering what tools you'll use to get the surface blemishes out. Presumably files, sandpaper and polishing mop? Also, was it TIG bronze welding or oxyacetylene brazing that you used to add the supports in?

FINEFUZZ Posted April 27, 2018 Author Report Share Posted April 27, 2018 (edited) Bronze is soft, so I will rely on hand tools (files and sand paper) to finish the outside. I have a foredom tool (with a foot pedal) to grind on the inside surface. I may have to invest in a pencil grinder that can hold larger mandrels than my foredom will. All the supports were added in wax, but bronze TIG welding would be the process that is used. If I do encounter any large voids of porosity, I may need to enlist the foundry to fill them with that method. I see some porosity, but nothing that cannot be dealt with by burnishing/ peening the surface with a hammer.

FINEFUZZ Posted May 3, 2018 Author Report Share Posted May 3, 2018 I bought a pencil grinder to remove material from the inside of the casting. I like this tool, it is proving to be quite effective. Quote Link to comment Share on other sites More sharing options...
FINEFUZZ Posted May 4, 2018 Author Report Share Posted May 4, 2018 Grinding in low light is proving to be preferred method. Out in the sunshine, the reflections cause temporary blindness. The goal is, however, to cause temporary deafness. Quote Link to comment Share on other sites More sharing options...
Prostheta Posted May 4, 2018 Report Share Posted May 4, 2018 That looks a very satisfying pursuit. I doubt that you'll get the old metal flu from grinding her up or lose your sense of smell, but hey! Quote Link to comment Share on other sites More sharing options...

I doubt that you'll get the old metal flu from grinding her up or lose your sense of smell, but hey! Yeah, I am not messing with that. I wear a respirator. I can't decide if aluminum welding fumes are the worst I have experienced, or if it is the exposure to burning and sanding super glue. But yes, I may end up with no sight, no sense of smell, and one or two less fingers at the end of this process. Will I be too crippled to play a guitar?

Prostheta Posted May 4, 2018 Report Share Posted May 4, 2018 It's saddening that so many of us expose ourselves willingly to things that wouldn't be acceptable in a workplace. The respirator is key. Quote Link to comment Share on other sites More sharing options...
FINEFUZZ Posted May 22, 2018 Author Report Share Posted May 22, 2018 Lots of filing to get surfaces back to a smooth plane where metal shrank to form concave areas. Now that I have the top surface established, I can define the edges of the surfaces that surround it. 1 Quote Link to comment Share on other sites More sharing options...

Mr Natural Posted May 23, 2018 Report Share Posted May 23, 2018 wow- this has been an education. How many hours do you have into that top/body now? bonus points for the foggy geezer in the shot above- how was it? 1 Quote Link to comment Share on other sites More sharing options...

I have not been keeping track of the hours too well. maybe 60+ in modeling it on the computer 25+ preparing for casting 20 in sanding grinding I usually only spend an hour or two working on it every other day, and lately the work has started demanding more muscle. After a couple of hours my hands a beat, and to tired to practice the guitar. I would like to do a demo of this guitar when it is completed, but I need to greatly increase my playing skills before that happens. The Foggy Geezer is a very well rounded IPA, and it is my favorite IPA at the moment. Although War Pigs it is a collaboration between 3 Floyds and Mikkeller (two of my favorite brewers), it seems like it will be a permanent release. The Geezer is definitely hazy and dank ( but not resiny) and it is also fruity and very easy to drink. Their Lazurite is also good. Highly recommended!

Once I get the outer surface defined, material will get hogged out of the inside with the goal of achieving a .125" wall thickness. When I picked it up from the foundry it weighed eight pounds, but it needs it to be closer to six pounds. This weight was prior to having the sprue bases removed and flash ground off however.
