Probably a final update to this post. I am now successfully drilling down to 0.3mm. The smallest I have tried so far. No issues, perfect hole size. I broached slightly from the bottom to remove burr / material that was deformed, but I attribute that probably to the fact I didn't drill the piece...

Hi! I am located in Central Texas area. I can meet anywhere from Waco to Frisco, Joshua to Waxahachie, and anywhere in the DFW area. Also open to shipping. I really need to make small pins (around 1.12mm) for a project. Along with some other basic turns. For the time being. I am looking for...

Neat! Thanks for sharing. Mine is a Cameron 164 I got used from ebay for what I would say it a pretty good deal. There were some others on there, but their condition was... sketchy looking on surface level. While I have you here, there is one question I have. Has your motor ever given off a...

This ended up being 100% the issue of my runout. However, it is not something I can fix with the tools I have. There were some work arounds but in the end my holes were still not concentric and were oversized by 0.05mm. Unacceptable when the material I have to play with tapping is only 0.1mm. In...

Well the taper on the spindle is at 0.01 runout. I took off the chuck and cleaned everything well with acetone and TIR appears to now be at 0.03mm. (previously .04) So either cleaning helped, or maybe the way I fit it counteracted the taper runout? Or heck, could be that I just rotated the...

I've put a ER11 collet chuck on it now and my static TIR with a cheap collet (around $15) seems to be 0.04mm now. Down from 0.1mm. Not too bad. Guess I'll try my operation again now and see how it goes. Edit: Techniks 04211-1/8. Not sure how other brands compare.

Thank you all for the help. Also, I do think I found a major source of the vibration and runout from when the machine is running. If you look at the schematics in the manual here , it seems to be that there is a lot of play between the column and the bar that is driven by the handle / ratchet...

I'm not trying to seem sarcastic, but if that's not how you do it, then what is the purpose of the spot drill that exist at that size? I see spot drills from 0.1mm to 1mm. etc. Or do you just mean it's usually not necessary? It is a jumper (a spring, of sorts) for a wristwatch. And the main...

interesting. I think I will pick up a 0.4mm carbide drill from mcmaster. Still 3mm shank, but the cutting length is a bit shorter at 4.8mm. I see what you mean about the center punch. How can I accurately center my workpiece to drill on the intersecting scribe in the drill? I do have one of...

I'm sorry I don't quite understand. I just assume collets would be better, I suppose. As I do also see them on premium sensotive drill presses such as here and here. I almost won a Levin, but I was outbid by $50. Anyways I digress. If I want to drill a locationally accurate hole, but I have...

You can find images of my personal machine here: Hamilton Sensitive Drill Press - USA Though those images are before the belt and idler replacements. Here is one updated image. you can find images of my personal machine here Hamilton Sensitive Drill Press - USA Though those images are from...

Hello! I have a Hamilton sensitive drill press (model A-M) that uses a JT1 tapered (<-- I think) jacobs chuck, and maxes out around 7k rpm. The runout from the shank of a 3mm bit is 0.08 - 0.1mm. The runout of the spindle just above the chuck is 0.01mm. As I said before, I'm not positive of the...
