put the measurements on a piece of paper, and then transfer those measurements directly to the piece.

But what if there were a way to do most of the measuring in one step? E.g.

I think the worst part of this hole drilling business, besides the bad puns, is doing all the measurements that determine where the holes should go, plus marking these measurements on the work piece, etc. Seriously folks, drilling holes can be tedious, especially for projects demanding a large number of holes i.e a whole bunch of holes. The words "drill" and "bore" are synonyms. On that point, I’ve also been considering a probe and a square/corner fixture, which would help with this significantly.Drilling holes is boring. Indeed, I can avoid not re-zeroing, but a) sometimes I’ll do other projects not involving this fixture origin (so now my zero is moved), b) I’ve heard inklings that power cycles and re-initiating is not ultra reliable on positional repeatability, and c) given b… I admit I’m trying to avoid re-drilling locating holes each time (which is the “easy” way to just make sure the origin is correct), so getting back to the same fixture would be awesome. I was able to bottom out and have very good fit, but I also had to tap in the dowels and use a pliers to get them out! Still re-running two bore operations still results in this phenomenon of being able to push the pin in to some depth (wobbly), and then getting tight, which I’ve taken as meaning I have a tapered hole. operation, surprised you use a contour for a circular hole? I think my last iteration creeping up on the proper ID would result in similar operations, though a 0.2mm stepover is 0.007in, and I was bumping ID by 0.001 (so maybe rubbing vs. refinding my pin hole…Īnyway, consider this a general inquiry on what people do for two-sided and making it easy to re-locate, get consistent/accurate positioning, etc. In this way, I’m now locating against two edges which might be less prone to slop (at least given my inability to make perfect locating holes for the pins), and I think it will be easier to just locate off two edges vs. I am considering switching to machining a simple rectangular contour into my stock from the top (so just take off ~1mm on each side at a depth of ~6mm, and using an embedded square in my wasteboard to position.

In this way I only have to face one side, machine halfway down, and since I’m zeroing z off the bottom (which was the top), I don’t have to worry about exactly thickness when it comes to hitting the halfway point of the part. I have considered making a pin hole or locating to one, then clearing machine offsets and recording the absolute position… would this be reliable enough?ĭoes anyone have any tricks for getting holes with hardly any play (yet still allowing pins to go in/out freely), and/or how you design parts and flip while maintaining the WCS between each side? I have been doing symmetric parts, and define a top setup that uses the pin center for x/y and stock top, then a duplicated bottom setup that uses the same x/y, but the wasteboard for z. similar to above, but explicitly: having a jig and re-creating a part after a power cycle/reconnecting to the Shapeoko.re-finding locations: I have been using this trick, but either that method is also subject to mis-alignment, or the issue above causes there to be enough play in the location that I get steps/mis-alignment when I do two-sided machining.Is this an inevitable problem with a stock z carriage, or given a 1/8 bit boring down ~12mm? I’ve tried two passes, doing a conventional and climb, etc. I tried peck drilling with a 0.25in and the fit was wobbly.

I’m thinking this is bit flex? I’m doing a bore with a 1/8 bit.
