Model Forum / Radio Controlled / Land Models / September 2006friggen allen keys
i snapped the engine brace today http://www.users.on.net/~annecarl/IMG_3372.jpg , i changed from high speed to low speed went to accelerate and the thing just back flipped over backwards landing on the engine, was running with no cover and no roll bar yet :(. I got a dynamite engine brace before i even got the car as everyone suggests its the first thing that breaks. The brace has 2 screws on the underside and 4 ontop, i managed to get 5/6 off the last one refuses to come off! The allen key is all twisted up and bent outa shape friggen screws! What do you guys suggest, where can i get some decent allan keys?? Ive tried the hardware store but all they have are cheapo ones, the screw has a 1/16th head and they have blue thread lock on them. I tried heating the screw with the soldering iron but it doesnt seem to put any heat into the screw and i dont want to use a lighter there are lots of plastic parts around. I was running the car in the street yesterday and they guy from across the road came over to check it out, turns out he has a stampede by traxxas we were going to take them down to the bmx track tomorrow. Ill chuck the lst into the car tomorrow and drop into the lhs on the way home from work see if they can take it out/supply me with a decent 1/16th and still take it to the bmx track http://www.users.on.net/~annecarl/ - for a few other random pics >i snapped the engine brace today > http://www.users.on.net/~annecarl/IMG_3372.jpg , i changed from high [quoted text clipped - 22 lines] > > http://www.users.on.net/~annecarl/ - for a few other random pics Yup, the damn things are so annoying aren't they? My best ever RC buy was a Hudy 2.5mm one www.topoptions.com sell them, they're not cheap at £8 a piece mind you, but they are so, so handy.

Oh just checked the site and they don't seem to sell them anymore. Still, good quality hex drivers are, IMHO, worth every penny.

Still, > good quality hex drivers are, IMHO, worth every penny. slot the offending hex screw with a dremel, and back it out with a flathead screwdriver. Oh and I'm 2nding the high quality hex driver advice. On the other hand, the black hex driver packs at the hardware store aren't nearly as soft as the ones that came with the kit. Final cheapo option is to dremel the end off of the twisted hex driver to use the pristine hex furthur up the shaft. SignatureJustin Mahn >>> Yup, the damn things are so annoying aren't they?

Yup, I've done both of things before myself as well :) SignatureDan - on his PC > slot the offending hex screw with a dremel, and back it out with a > flathead screwdriver.

The top of the hex driver still fits the screw just the whole thing is all twisted up i try to undo the screw turning the hex driver/allen key with a pair of pliers. Ill see if the lhs has something that can undo it ok will see if i can get a hudy 2.5mm >> slot the offending hex screw with a dremel, and back it out with a >> flathead screwdriver. Oh and I'm 2nding the high quality hex driver [quoted text clipped - 15 lines] > > ok will see if i can get a hudy 2.5mm Buy a Dremmel or other rotary tool. You will LOVE it and use it more in this hobby than any other. I'd be a mess without my Dremmel. Using the cut-off wheel, as Justin suggested, slot the hex screw so you in effect make it a slotted screw, then use a flathead screwdriver to get it out. Worst case scenario, if the screw still won't come out and it's a button head screw (top of screw is not flat with surface but elevated, use the Dremmel's grinding wheel to grind the top right off and pull the piece off, then use a pair of small vice grips on the part of the screw sticking out and back it out that way. You will not regret buying a Dremmel. If you do after 6 months, I'll pay for it! I use it for everything: busted screw removal, trimming bodies, sanding the chrome off wheels before gluing, etc. Doc This screw is flush with the frame, what would you do in this scenario. to cut a grove into the top to attack it with a flat head screwdriver would also meen cutting into the frame. I shall get a dremel :) ive been meening to get one anyway now ive got a good excuse If the screw is not stripped/rounded and your hex keys ends are not rounded... with the allen key inserted. tightly put a pair of vise grips on the allen key fairly close to the screw.(Rotate grips counter-clockwise) Either it will come out, the hex key will round or the screw hex will round. If the screw hex rounds, you don't have many options..the main one being what others have said..(slot the screw) > This screw is flush with the frame, what would you do in this scenario. > to cut a grove into the top to attack it with a flat head screwdriver > would also meen cutting into the frame. > > I shall get a dremel :) ive been meening to get one anyway now ive got > a good excuse > This screw is flush with the frame, what would you do in this scenario. > to cut a grove into the top to attack it with a flat head screwdriver > would also meen cutting into the frame. > > I shall get a dremel :) ive been meening to get one anyway now ive got > a good excuse I've had (limited depending on how hard the screw is, allen bolts are usually hardened) success drilling the head of the screw out. Since its a hex, the drill bit centers pretty well. This way stops any slots cut into the chassis when using a dremel.

If i drill the head off im guessing the brace should then be able to be pulled out. The only problem that leaves me with is i need a replacement screw i have a set i bought off ebay http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&ih=013&item=230019459713&rd=1&s spagename=STRK%3AMEWN%3AIT&rd=1 but the screws are a tiny bit bigger, they are a very tight fit. To make it worse i bought a set of allen keys frmo the hardware store the guy recons it would remove the screw no worries, they have a rounded end.. well DID have a rounded end, that end is now stuck in the head of the screw, it just snapped clean off with a bit of pressure. DAMB THESE HEX SCREWS WITH TINY HEADS!!!! >> I've had (limited depending on how hard the screw is, allen bolts are >> usually hardened) success drilling the head of the screw out.

Yep, and if you pull *and* wiggle on the bracket back and forth I'm sure the bolt will pull through the hole easy as pie! > The only problem that leaves me with is i need a replacement screw i > have a set i bought off ebay > http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&ih=013&item=230019459713&rd=1&s spagename=STRK%3AMEWN%3AIT&rd=1 > but the screws are a tiny bit bigger, they are a very tight fit. Hmm, I'm not quite sure I follow. Are the new screws a bit smaller than the old ones? I dont think that will make any difference. If the new ones are bigger do they still fit? if they do, no worries :) > To make it worse i bought a set of allen keys frmo the hardware store > the guy recons it would remove the screw no worries, they have a > rounded end.. well DID have a rounded end, that end is now stuck in the > head of the screw, it just snapped clean off with a bit of pressure. > > DAMB THESE HEX SCREWS WITH TINY HEADS!!!! Those rounded hex keys are designed to undo hex bolts on an angle or when you cant turn the key exactly at in line with the bolt. I certainly wouldn't heave on them as you have found out :) If you now have a bit of allen key stuck in the hex, its made the drilling job a thousand times harder :) Allen keys are not at all soft so you might be drilling for a while, plus you've lost your guide! You could try a punch, punch a dent into the allen key, then drill like buggery? Cheers Dre >> I've had (limited depending on how hard the screw is, allen bolts are >> usually hardened) success drilling the head of the screw out. Since its [quoted text clipped - 22 lines] > > DAMB THESE HEX SCREWS WITH TINY HEADS!!!! Btw, I dont suppose you could take a photo of the problem bolt and surrounding area? That would help a lot as there might be some other tricks available :) Cheers Dre lol i was going to but i left my camera plugged into pc which means the camera stays turned on and the batteries are flat. they are charging but its too late ive started drilling with bad luck so far, that tiny bit of allen key in there is very tough metal the drill bit cant get through it, instead its mincing up the rest of the screw. I think ill have it soon just grinding bits away at a time got it out! after drilling for a while i gave up nothing was happening, i got a pair of vice grips and twisted the bottom of the engine brace that broke the thread lock loose, i then used a flat head screw driver that kinda fited into my drill holes to hold the screw while i twisted the engine mount bit at a time. Got the new one, im about to remount the engine ill post some pics soon once batteries are charged ok here are some pics, ive left them the same res as my camera takes em http://www.users.on.net/~annecarl/IMG_3376.jpg you can see the different size tip on the screw i had to replace i managed to get it to fit by puting the new brace into a vice and screwing a screw in and back out easing it in bit at a time eventually i got it all the way through http://www.users.on.net/~annecarl/IMG_3378.jpg can see the screw and broken mount and the beers that had to be drunk to supply energy to do the work :) http://www.users.on.net/~annecarl/IMG_3379.jpg new mount going to the bmx track sunday now, ill get a tank of fuel thru the engine tomorrow morning tho ive got the morning off :) i get married the following w/e the 30th! > ok here are some pics, ive left them the same res as my camera takes em > [quoted text clipped - 15 lines] > > i get married the following w/e the 30th! All sorted now then :-) Good man. Get it out there and get it beaten to a pulp ;-) I might take the Revo out later... SignatureDan > ok here are some pics, ive left them the same res as my camera takes em > [quoted text clipped - 15 lines] > > i get married the following w/e the 30th! Good stuff. Yep, allen keys are hard as hell, hence why I said 1000 times harder with the bit stuck in the hole :) Now you can get it out there and let it loose! Cheers Dre I got me a dremel today it has a nifty flexable shaft to get into hard to reach places. im off to go dremel some stuff :P After playing around tool making for years the only keys worth havin are the genuine UNBREAKO brand you wont regret buying them ; -- olmo > After playing around tool making for years the only keys worth having > are the genuine UNBREAKO brand you wont regret buying them ;) Unbreako eh? That has inspired me.

On the other hand, a small bit of slotting on the chassis will not affect the performance in the least.

You may be able to remove the allenhead by rotating the broken piece and using the allen key to hold it in place. If worse comes to worse buy the dremel anyway and use the cutting tool to cut the broken piece off and replace the screw. It sounds like you might have to replace the screw regardless and your not going to use the mount again. I use my dremel for everything not just RC but its also good for trimming new bodies, tyre cutting, engraving, making parts a little more light weight or just for polishing the scratches out of the head you just scratched. :-) Cheers |
