2011年12月1日 · They are and they cut like crazy but a drill doctored bit cuts a more accurately sized hole almost every time. If you have a precision ground 1/4" roll pin, take a well hand sharpened 1/4" bit and a drill doctor sharpened 1/4" bit and you will see the difference. The doctored bit hole will have a tighter tolerance fit.

Done it on a grinder, a belt sander and with a hand file. Use a GOOD hand file and it can be done. I have even sharpened carbide bits .5mm diametre with a diamond stone. No thats not a typo, .5mm is correct. I have a Drill Doctor and find it more consistant than my hand sharpening. I use it or every thing I can chuck in it.

2023年10月3日 · 10. Our plan to resolve this was pretty straightforward: We’d just re-drill the hole to 1/2-inch , and make sure that the bar can properly rotate once installed. We cut down some 5/16-inch bolts for use as alignment dowels. 11. We clamped together the bracket and reamed the hole back to 1/2-inch with our drill press.

You leave the chain on the bar and just do a light touchup on the teeth when you fill it. It comes with an angle guide to make it nice and easy.

2018年8月26日 · Once again, nothing in this job is "hard" just a lot of repetitious work to find and cleanly drill all the spotwelds. All I use is a 1/8" and a 5/16" drill bit to do the job. The clamp thing is because it is hard to push a drill sideways and I was getting tired! Ready for new panels . Pete

2023年8月6日 · Doing good work in a decent amount of time requires better tools. Yes you can trade time for better tools. But it's a bad bargain. My 60 gallon air compressor appreciates the little 1/2 hp air compressor to boost the air volume when I'm really going at it. Then the tool itself mattered too. At first I was a snob and used only Snap On grinders.

2022年7月3日 · Need input from anyone familiar with this. This is a triangulated not a parallel but I don't know if the top and bottom bars should still be parallel or not. You can see in the photo they are not. I could drill the lower axle end mounts and move these lower bars up a bit if its an issue, Im just not sure it matters with a triangulated setup ...

2024年8月10日 · Project scope creep on a step-by-step basis can get really expensive when we have to go back and re-engineer stuff after the fact. Meanwhile.. next week i will be trying to frame an opening for a 14' foot tall roll-up door on a pole barn …
