Supporters Rogerborg Posted April 12, 2018 Supporters Share Posted April 12, 2018 I erred on the side of caution, but 2mm is likely fine, it's tough stuff. Link to comment Share on other sites More sharing options...

CiderPunk Posted April 13, 2018 Share Posted April 13, 2018 I'll go for 4, I like the look of rogerborg's Link to comment Share on other sites More sharing options...
Arwen Posted April 13, 2018 Share Posted April 13, 2018 I simply bought "sample" squares from this guy on ebay., Works a treat. Just lightly sanded the edges to make them less sharp. https://www.ebay.co.uk/itm/CLEAR-POLYCARBONATE-LEXAN-MAKROLON-SHEET-UNBREAKABLE-MARLON-PALRAM-PANEL-/360813914102?var=&hash=item54022f67f6 Edit: Picture... I used double sided foam tape to stick it to the gorpo frame Link to comment Share on other sites More sharing options...
Supporters Rogerborg Posted April 13, 2018 Supporters Share Posted April 13, 2018 Samples are a smart move if you don't want to do too much work. I had to do round covers to fit some sights exactly though, so just went for an A4 sheet of 4mm for £3.25 https://www.ebay.co.uk/itm/361195046704 4mm really is more than sufficient, and cuts fine with a fine tooth metal jigsaw blade. A hacksaw might take some time to get through it, so I would agree with going for 2mm. Link to comment Share on other sites More sharing options...
Supporters ImTriggerHappy Posted April 13, 2018 Supporters Share Posted April 13, 2018 I make quite a lot so machining them is the only way. Link to comment Share on other sites More sharing options...
CiderPunk Posted April 20, 2018 Share Posted April 20, 2018 Quite happy with how that came out! Used M3 bolts, pro-tip, drill the poly-carbonate first, then mark and drill the aluminium, would have been a lot easier with a drill press! Link to comment Share on other sites More sharing options...

Heh, oops. I've since realised that a single bolt in the middle lets you rotate the polycarb out of the way in order to clean it and the sight.

MisterG Posted April 20, 2018 Share Posted April 20, 2018 I bought a sample piece from ebay 10cm square x 2mm, was only about 99p. Haven't got round to making it yet, so the tip about the single bolt was timely. Cheers G Link to comment Share on other sites More sharing options...

Supporters Rogerborg Posted April 20, 2018 Supporters Share Posted April 20, 2018 I did it that way at first and got some fogging. That's why I shimmed it out with rubber, and am OK with being able to rotate it. Link to comment Share on other sites More sharing options...
warlord Posted April 20, 2018 Share Posted April 20, 2018 Velcro FTW. Gives it the ability to flex when it takes a hit. Super sticky from Halfords. It's going nowhere. Link to comment Share on other sites More sharing options...
MisterG Posted April 20, 2018 Share Posted April 20, 2018 Great tip. I have velcro like that already. Project for the weekend \o/. Field testing next weekend. Link to comment Share on other sites More sharing options...
Supporters Rogerborg Posted April 20, 2018 Supporters Share Posted April 20, 2018 That looks like a winner. Actually, I've some some spare bits of 3M double sided pad from a helmet mount that would probably do a decent job. Link to comment Share on other sites More sharing options...
CiderPunk Posted April 20, 2018 Share Posted April 20, 2018 I've got some of that kicking around, if this does fog up i'll stick in on with that! Link to comment Share on other sites More sharing options...
warlord Posted April 20, 2018 Share Posted April 20, 2018 I only came up withis as I had an RDS shot out on my M4. Then a protector shot out on the M4 the next game! Then when I moved the RDS to the AK there was no room for a protector. Bought a sheet of polycarb and a bit of dremelling later - done. Got loads left to make another if this fails. So fair it's lasted quite a few games. Added benefit, eay to take off and clean. Link to comment Share on other sites More sharing options...

MisterG Posted April 25, 2018 Share Posted April 25, 2018 This was my orginal idea. Lens cap arrived today. I put a polycarb disc inside the lens cap to use as protection. Link to comment Share on other sites More sharing options...
