dlaery Posted April 22, 2011 Report Share Posted April 22, 2011 I read where a lot of guys here polish the jigheads before painting. Could someone tell me what is used and what this process does? Thanks. It might have been referring to polishing the cavity of the mold in order to make a smoother finish on the poured heads. Polishing jigheads would be very hard to do.

mkvnmtr Posted April 22, 2011 Report Share Posted April 22, 2011 I do some large jigs that we use a file and sandpaper to clean up before painting. Mostly butterfly type jigs. Only do it on things where a fancy paint job is what makes the sale. Quote Link to comment Share on other sites More sharing options...
Basseducer Posted April 23, 2011 Report Share Posted April 23, 2011 gdowney, I break off the sprues and it leaves a scar on the jig. I then use a hard leather disk attached to a sewing machine motor to "buff" or "polish" the scar smooth before painting. Hope this helps.

gdowney Posted April 24, 2011 Author Report Share Posted April 24, 2011 Basseducer. Is there another way to polish this area? I have a Dremel Tool and tried a polishing wheel on this area but it did not work. Thanks for all the help guys. Quote Link to comment Share on other sites More sharing options...
mkvnmtr Posted April 24, 2011 Report Share Posted April 24, 2011 Try a sanding wheel. I use 220 grit. You need something that will cut but still be smooth enough. Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted April 24, 2011 Report Share Posted April 24, 2011 Try a sanding wheel. I use 220 grit. You need something that will cut but still be smooth enough. I just went down to the cave and tried the Dremel drum sander. It removes the blemish very fast, but leaves a heavily scratched surface. Next I tried the Dremel flap wheel. Still harsh, but a distinct improvement. I then tried a regular flap wheel in the drill press, on a slow speed. I think that this is the answer. Hands free, much softer cut but still fast. Ideal if you have hundreds to do. Dave Quote Link to comment Share on other sites More sharing options...
Basseducer Posted April 25, 2011 Report Share Posted April 25, 2011 You can also use your dremel with the wire wheel. It's very fast and leaves a smooth surface. The leather disk I use is mounted to the bench and has a foot peddle, leaves both hands free to handle jig. Quote Link to comment Share on other sites More sharing options...

schmink Posted April 26, 2011 Report Share Posted April 26, 2011 I use 600 grit black wet/dry sand paper. Quote Link to comment Share on other sites More sharing options...
bakgat Posted May 9, 2011 Report Share Posted May 9, 2011 I have tried using sand paper and it just takes too much time for me. What I do now is use a Stanley knife and pull it over the scar at a vertical angle to the jig body, its almost like scraping the mark off. By doing this I get a very smooth finish.

I do it the same way .. got an old wooden handel bait knife and every so often I grind it a little to keep the right edge to it. JSC Quote Link to comment Share on other sites More sharing options...
