Drilling holes in car frame. I need to drill 18 12 holes in my frame for a c notch. Permitted hole patterns in the frame side member. 25mm wide masking tape over the place to be drilled. Filling it back up with a bolt will get you back to 80 90 as long as its less than 75ish width of that side of the beam. The frame side member flanges are subject to the greatest stress which is why you should only drill holes in the beam web. To prevent the marking tool or drill sliding off course put a cross of 1 in.
Generally drilling a hole up to half the width of a square tube will cut the strength by approximately 13. Drilling a small hole in the frame or even through the floor or similar for wires or screws to go through is no problem but there are a few things to remember. All holes in the frame side members increase the risk of fractures. I started out with a small bit and then got gradually bigger. The drilling of holes in the flanges in the area extending 100 mm in from the frame side member rear edge is permitted. I spent 15 on a titanium bit but so far this thing sucks.
Car bodywork is curved and shiny and scratches easily. Over half the width 23. Always know what is on the other side of what you are drilling. Drilling a hole protect the bodywork with a cross of masking tape and mark the spot to be drilled in pencil. What kind of drill bit are you guys using. It took me an hour to drill 2 new holes in my helper bag brackets.
Drilling holes in the frame side member flanges note. Once i got to the 12 it didnt do shit.
