I want to know because part of my Radio Controlled car's engine came off(screw tread).I tried "arildite" but no good, now im using "quick metal". but i havent run my car yet.CheersChris Beattie Link to comment Share on other sites More sharing options...
Ed Posted January 8, 2004 Share #2 Posted January 8, 2004 I'm not sure if you have it available down under but we have a product called " J-B Weld" works wonders with metal. Link to comment Share on other sites More sharing options...
Mr Camouflage Posted January 8, 2004 Share #3 Posted January 8, 2004 Can you re tap the hole and use a larger screw? Link to comment Share on other sites More sharing options...
inline6 Posted January 8, 2004 Share #4 Posted January 8, 2004 We used Loctite (Loctite Corp-- like the thread lock) products to bond an aluminum skin to the tubular steel frame on our SAE formula race car. They should have something that will work.SAE = society of automotive engineersCheck out the most recent car here:http://www.vtmotorsports.comI was on the 1991 team.Garrett Link to comment Share on other sites More sharing options...
EScanlon Posted January 9, 2004 Share #5 Posted January 9, 2004 I also have an R/C boat that had had the muffler mount screw holes broken off (accident that sheared off the muffler). Realizing that I had the choice of buying a new $40 muffler or giving it a shot at repair, I used some JB Weld.That stuff not only allowed me to repair the mount, I also re-tapped it with the original thread diameter and pitch so I did not have to find new muffler screws.As you know, the muffler and cylinder head are the two parts of the motor that get the hottest. I've since used that motor about 15 DAYS worth of boating and couldn't guess at how many individual runs that amounts to, at a guess figure 5-8 runs per day averaging 15 minutes or more.JB Weld withstands temperatures up to 550° F if I recall, that should be about 288° Centigrade. The key to working it is to make absolutely sure there isn't any grease or oil on the surface, mix it real well and let it sit no less than 24 hours before you get in there and start trying to work it. It sets best if the temp is maintained over 70° F (21° C) for the whole curing cycle. Although you can "speed set" it with a hair dryer or a heat gun, it can make it real runny at first and cause you more problems if you aren't careful.Hope this helps.Enrique Link to comment Share on other sites More sharing options...
datto_240z Posted January 9, 2004 Author Share #6 Posted January 9, 2004 Maybe i explained it wrong, there is a small cylender that comes out of the bottom of the engine that you screw onto(via chassis). That whole cylender came off. This JB weld sounds perfect but i dont know if any exists in Australia... Cheers Chris Beattie Link to comment Share on other sites More sharing options...
Mr Camouflage Posted January 9, 2004 Share #7 Posted January 9, 2004 Marlows (now Super Crap errrmm, Cheap Auto) sell, used to sell steel reinforced putty. Cant remember the name of it. Hang on i'll go in the garage and see what its called.............................called Quick Steel. Its a grey putty that you kneed together, then is sets hard as steal. then you can file it or whatever. Link to comment Share on other sites More sharing options...
datto_240z Posted January 9, 2004 Author Share #8 Posted January 9, 2004 got some of that... its pretty crappy though, it doesnt set. Maybe my tube is too old I dont think it will hold the heat though... Cheers Chris Beattie Link to comment Share on other sites More sharing options...
