BS1066 0 Posted August 30, 2005 Report Share Posted August 30, 2005 I hate resorting to WECSOG methods, so rather than hammering the gas block off I made a jig to press it off. The attached pic shows everything used in the jig. Quote Link to post Share on other sites
BS1066 0 Posted August 30, 2005 Author Report Share Posted August 30, 2005 Dimensions on the "horseshoe" that slips over the barrel and sits against the reciever/front trunnion. I used a piece of scrap steel 1/2" thick. The barrel measures 1.127" in diameter, I cut a 1" hole and ground away the inside till it fit over the barrel. Quote Link to post Share on other sites
BS1066 0 Posted August 30, 2005 Author Report Share Posted August 30, 2005 I then made an adapter to fit the bottom side of the gas block. The small hole is just larger than a 5MM bolt, which is used to attach the adapter to the gas block via the fore grip bolt hole. When mounted, an 11/32 drill bit will fit through the larger hole in the adapter and the corresponding hole in the gas block. Between this and the shoulder milled into the adapter, little force is placed on the 5mm bolt so it won't shear off. Quote Link to post Share on other sites

BS1066 0 Posted August 30, 2005 Author Report Share Posted August 30, 2005 Mods to the shorter bolt. I drilled a 3/8" hole in the head of the bolt, this corresponds with the dimple in the face of the gas block adapter. A short 3/8" diameter pin fits between them, keeping the bolt in place while pressing off the gas block. The washers let the bolt's head turn against the adapter without galling. I used 5/8" course thread bolts and a coupler nut. I had grade 8 bolts on hand, but the coupler is grade 5 and I figure grade 5 bolts would hold up just fine. Quote Link to post Share on other sites
BS1066 0 Posted August 30, 2005 Author Report Share Posted August 30, 2005 The jig assembled on the weapon. I'd already pressed the block off when I took the pic, I actually started with a shorter bolt, pressed the gas block about 1/2", then removed the bolts and swapped out to a longer bolt. I used a 3", a 3 1/2", and a 4" bolt to press the gas block off. During the operation I held the coupler nut with a wrench and turned the short bolt with another wrench. The gas block pressed off with little effort, without damage to either the gas block or the barrel. Quote Link to post Share on other sites

JiiKoo 0 Posted August 30, 2005 Report Share Posted August 30, 2005 How did you put the gas block back? Did you heat the gas block and freeze the barrel? Quote Link to post Share on other sites
BS1066 0 Posted August 30, 2005 Author Report Share Posted August 30, 2005 I haven't put it back yet, right now I'm more interested in making another adapter to press out the barrel itself. The hot/cold trick may get the gas block back in position, if not I can use the adapter and press it back in place on a shop press. Quote Link to post Share on other sites
steve 1 Posted September 1, 2005 Report Share Posted September 1, 2005 Excuse my ignorance but what dose WECSOG mean? Im asking because I think that I may have WECSOG the front sight base off of my 7.62x39. That is some nice tooling that you have made. Quote Link to post Share on other sites

BS1066 0 Posted September 1, 2005 Author Report Share Posted September 1, 2005 WECSOG = Wylie E. Coyote School Of Gunsmithing. <{POST_SNAPBACK}> Not that there's anything wrong with that, sometimes a bigger hammer is the only way to get the job done. Quote Link to post Share on other sites
