Two tips to consider perhaps. First is the cleanest side of the hole will be whichever side the smaller part of the knockout die is placed - the backside might need a touch with a rat tail file to get back to flat. Second is knockout dies last a good long time - if you use some oil. Oil the threads and the face/edges of the small diameter [lightly] to prevent galling or edge chipping if going through thicker steel. Tool not only lasts longer, but you get a cleaner hole. First thing I do when I get a new bolt/drawstud for knockout dies is to put some gear oil on those threads so it's ready to go.

Thank you so much for this great video!! Just helped my favorite son do 13 holes in 182 panel to modernize the 1956 panel with punch and template. .120” was at limits but the punch held up.. Thank you, Paul.

I did my instrument panel, using Front Panel Express - free download layout software that includes pricing. My panel cost $107US (small 1 seat homebuilt) CNC accurate, with choice of thickness and finishes.

The best tool is a CNC vertical mill for doing panel, and I wish I could have had one years ago when I worked as a structural mechanic on aircraft.

Use a simple layout tool (like google sketch up) and send it to a local fab shop. Might be kinda spendy but if you need a large cutout for a electronic display (not just simple round gauges) it would be a better solution.

When doing a complete panel, it would probably be prudent to mark the positions of the holes with a Sharpie. That way, if you make a measuring error, (or just forget what goes where), you'll see it before doing any cutting.

Back in the day when we used to build Valve amplifiers with aluminuim chassis we used the same type of punch to put valve hole and other holes in the chassis.

Back in my day we very successfully used hole saws and laid out the small holes with a very accurate blueprint. Made some nice panels and never missed a hole. Oh and we had a slow speed floor mounted “huge” drill press.

Are those cut-outs sometimes hard to remove from the punch? If so maybe try compressed air. I know compressed air works REALLY good for separating nested 5-gallon buckets, trash cans, etc..

So what is a good process if your panel is fiberglass? Can you still use a punch without shattering the glass?

@go2cloudbase3 жыл бұрын
Will this tool also work for a fiberglass panel, about 3/16th inch thick? If it cuts and doesn't crush the fiberglass around the hole it seems it would work well.

Why would you not use the instrument as a template? Never built a plane, but I've used that method dozens of times and always get perfect fit...if you know how to center your punch correctly in the instrument holes.

You say that hole saws are impractical because the appropriate sizes are not typically locally available. The Dies/punch (appropriate size or not) is even LESS likely to be available. Where do you get them?
