However, is there some way I can rectify this mistake? I'm looking for something to fill the hole with and in which I can then make a smaller hole instead, I'm thinking it would have to have a fairly nonviscous consistency and then dry into something hard yet non-brittle enough to drill in. Has anyone done something like this or knows something that could work?]]> http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11234389.page http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11234389.page GMT Messed up gun barrel drilling - is it salvageable?
If you had a plastic rod the exact right diameter, you could use that, but I suspect that’s a bad idea as well.

Wellcome to Dakka. Hope you can get a more solid answer.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11234391.page http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11234391.page GMT Messed up gun barrel drilling - is it salvageable?
Though I'm not sure I'd recommend filling the whole thing in an redrilling, I'd probably be lazy and just use some greenstuff to narrow the opening at the end of the barrel to the approximate size.

EDIT: thinking about it more you could also obtain one of the numerous muzzle blast effect bits various companies make. Then it won't matter what the barrel is drilled to since it'll be covered by another bit.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11234392.page http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11234392.page GMT Messed up gun barrel drilling - is it salvageable? http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11234411.page http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11234411.page GMT Messed up gun barrel drilling - is it salvageable? http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11234463.page http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11234463.page GMT Messed up gun barrel drilling - is it salvageable? http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11234484.page http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11234484.page GMT Messed up gun barrel drilling - is it salvageable? http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11234505.page http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11234505.page GMT Messed up gun barrel drilling - is it salvageable? http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11234672.page http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11234672.page GMT Re:Messed up gun barrel drilling - is it salvageable? http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11235633.page http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11235633.page GMT Messed up gun barrel drilling - is it salvageable?

This would be my course of action, assuming that the outer barrel is salvagable. Otherwise, I support the transplant option ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11235699.page http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11235699.page GMT Messed up gun barrel drilling - is it salvageable? http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11235825.page http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11235825.page GMT Messed up gun barrel drilling - is it salvageable?

I found out that the best method to fill in the various holes/gaps in hips minis is to use the very plastic they are made of. Simply cut/scrap some plastic from the unused bits or even from a sprue and glue it (I use tamiya liquid for this or revel contacta) and after it is dry, if needed, use a file or sand paper.


yup, snip of a part of the spure, melt it into a small drop with a lighter and just pour it in the hole. or you can use thick plastic glue and let it cure for 6H before you make the hole again.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11235846.page http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11235846.page GMT Messed up gun barrel drilling - is it salvageable?

No, don't do this as it can produce hydrogen cyanide gas if any of the polystyrene burns rather than melting.

If you want to 'melt' polystyrene, use plastic glue as a solvent, not a naked flame. You can actually make a pretty decent filler/putty by dissolving bits of sprue in plastic glue.

But keep flames away from polystyrene.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11235925.page http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11235925.page GMT Messed up gun barrel drilling - is it salvageable? http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11237585.page http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11237585.page GMT Messed up gun barrel drilling - is it salvageable?

+1 for making 'Sprue Glue'. This stuff is amazing. And it's as easy as Duskweaver said - simply dissolve a bit of sprue with (preferably) Tamiya Extra-Thin Cement. There's no real recipe to it either, if it's too thick add more glue, if it's too runny add more sprue.

I use this for filling gaps these days too. It's quicker and easier to use than putty (in most cases). It's also really good for repairing things like incorrectly drilled barrels, which is something I recently repaired as well.

Good luck ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11237595.page http://www.dakkadakka.com/dakkaforum/posts/preList/801373/11237595.page GMT
