Finally someone who explains how to put them back together , been watching a lot of hot wheels modification videos and they always leave out the part where they get the car back in one piece. Great video 👍
there's no need for tapping if you use sheet metal screws- they cut threads into the post. tapping cast white metal is a waste of time cuz its soft metal.
quick tip,,,using the right type of tap eliminates the need to "reverse and break" the chip.. some taps are designed to push the chip back out the hole ,,, some push the chip forward,, some do neither... depends on the type of tap ..As a machinist I never use anything more than a 2 flute tap for hand tapping and rarely break a tap anymore...the cheaper 3 and 4 flute taps will break much too easy. the best tap for this process and material would be a "2 flute spiral point plug tap".It looks like that,s what your using in the video. hard to tell
It is indeed a two flute straight shank relief style. So the chips peel forward. Do you have a link to the style that ejects the chips? I've broken one of these tapping into the hot wheels metal due to galling.
It is a 1-72 tap. If you google "1-72 tap size" a chart will come up with recommendations for drill size etc. there are several sizes of screw and tap that will work for hot wheels. I just used 1-72 because my local bolt supply can get them.
Thank you for this video. Just have the right direction on how to remove and change the rivets. Just wanna ask if the M2 threading screw is just the same as the tapping screw you have used? It was like that's the only thing I can find in our country. The M2 tapping screw.
can you do this even on a diecast car that has relatively tiny rivets and posts? looking to customize one but the rivets (and assuming the posts as well) look much smaller in comparison to the other diecast cars i've seen
i do the racing champions micros (1/144). i use a .043 drill for setting the screws and #0 sheet metal screws with either pan or countersunk head. setting the screws should be the first step to minimize the chance of ruining a rivet post- do this before cutting the rivet lip. no tap needed for metal screws.
The tap peels metal off the side of the hole to create the threads. As that metal peels, it curls up in the tap reliefs. When you turn the tap backwards a bit, that peel breaks off the side of the hole. If you don't break the peel off periodically, you run the risk of the peel getting so large that it interferes with the new threads being created and will gall up the tap. This can damage the threads or jam the tap and cause it to break.
