bandaideman Posted February 14, 2020 Report Share Posted February 14, 2020 I am working on a dust collection for my Ex 21 like the one I have for my Dewalt. I am at a point that I need to remove the two screws on the side of the upper arm holding the cover on. the problem the screws seem to be in to stay. Any one have suggest of what to try. I am using the proper size driver or at least thought so it since it fit. I did not push the issue because I did not want to ruin the head of the screw. Any way if some one has a way of turning it out or size I should use to turn it out. Thank you OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...

OCtoolguy Posted February 14, 2020 Report Share Posted February 14, 2020 I like the idea of some sort of penetrating oil and let it sit overnight. I've never used PBlaster but I have heard nothing but good about it. Quote Link to comment Share on other sites More sharing options...

kmmcrafts Posted February 14, 2020 Report Share Posted February 14, 2020 If you use PBBlaster.. I'd make sure the saw is unplugged.. There is wires running from the power switch etc in that cover.. I'd also cover up the table of the saw to keep the oil from getting on it and then getting onto the next project you cut.. My Excalibur has hex head screws and requires an allen wrench to remove it.. and they was tight the first time removing them.. once broke loose they spun right out with my fingers so they wasn't really rusty or anything.. just tight, LOL.. BTW.. about the only thing that was tight on the saw too.. OCtoolguy and scrollingforsanity 1 1 Quote Link to comment Share on other sites More sharing options...
Jim McDonald Posted February 14, 2020 Report Share Posted February 14, 2020 They may have Loctite on them and let's hope it is blue--not red or green. OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...

JTTHECLOCKMAN Posted February 14, 2020 Report Share Posted February 14, 2020 An old trick we use to use out in the field is to try tightening first and this may break the seizure. You are not going to get any liquids inside but may get on table so take precautions. scrollingforsanity and OCtoolguy 2 Quote Link to comment Share on other sites More sharing options...
JTTHECLOCKMAN Posted February 14, 2020 Report Share Posted February 14, 2020 I saw this video on utube the other day and thought of Ray here who said to do maintenance on the Dewalt. This is probably the best video and most simple video I seen explaining what to do. In it it shows the screws you are talking about and they do not look hard to remove. But there is a tube of blue locktight so maybe they were locktight in. Good luck. https://www.youtube.com/watch?v=x42jZgEAUwM New Guy and OCtoolguy 2 Quote Link to comment Share on other sites More sharing options...
jerry1939 Posted February 14, 2020 Report Share Posted February 14, 2020 Two things that sometimes work: 1. Take a flat end punch the size of the screw head, & whack it with a hammer ("forcing it in further"), sometimes this helps break the bond. 2. If it's not a torx head, clamp the screwdriver shaft with a vice grip. Simultaneously hit the end of the screwdriver with a hammer & turn the screwdriver with the vice grip. This keeps you from slipping & rounding out the head of the screw. jerry tomsteve, scrollingforsanity and OCtoolguy 2 1 Quote Link to comment Share on other sites More sharing options...
rash_powder Posted February 14, 2020 Report Share Posted February 14, 2020 Acetone will dissolve loctite. Heat is always a great help in getting things loose. Use your wife's hair dryer or a heat gun, or if plastic is near put a soldering iron on the screw and heat that way. As mentioned before, your best bet would be an impact driver and a properly fitting bit for the screw. OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
bandaideman Posted February 15, 2020 Author Report Share Posted February 15, 2020 Thank you for all your responces. They are all great. I did get out the drawer with my allen wrenches actually 3 but just need the smaller ones. I chose my weapon and carefully turned and out they both came. Well that was great I finished my project but now need to get the tubing to stop the high pitch whistle. All is tight All is hooked in like it should be but annoying. Well I will figure it out. Thank you all for the help. I did replace the screws. may not be around much the old computer is like me old and forgetful I just finishing this and it took 45 mins from time of turning it on to getting in and to the forumn. . scrollingforsanity 1 Quote Link to comment Share on other sites More sharing options...
teachnlearn Posted February 15, 2020 Report Share Posted February 15, 2020 When I worked on a Honda motorcycle the screwheads always deformed so I used a manual impact screwdriver on them. Turned every time. Have had it around for screws that won't move since. Selection in link.
