There are all sorts of potential issues here, It may take some work to zero in on the root cause. One possibility is a slightly bent shaft that releases after a bit of pressure is applied. Surprisingly this is a common injury to dial indicators as the can get jammed into things, dropped or...

I’m not sure which clearance you are talking about but if you are talking dovetails I’d keep them as tight as reasonable. You want to avoid large gaps that would allow the tool holders to rock. A couple of thousands might be a good target. Basically tally a good sliding fit. Note that...

Best advice in the forum!!! As Ron points out Mach3 is on life support. If you want to stay in the Mach world go with Mach 4. On the other hand if you need a new GCode processor there are many option available these days. I would most certainly investigate the options available for...

I don't have web links but I know for certain there are conversion videos on the net. In the end the mount will be rotary table specific. As such you would want to look for info specific to your rotary table. The common approach is a bell shaped extension that can mount to existing...

Thanks for the little write up on pin vises and valve seating. One question though, why no power tools for valve seating? To add to this, pin vises can be supllemented with short sections of hex or round stock that one might have left over from a project. This is a usage I’m transferring...

The idea that the “new” chuck performs the same as the old suggest to me a spindle nose problem. Your runout values could be good or terrible blue depending upon where the measurements where taken. You really want a high precision dial indicator because measuring to a thousands isn’t good...

Clean is very important. It might seem silly to repeat this but it is the key to getting most sealants, tapes and glues to work correctly.

Hi Gordon; Not being an engine expert here I'm going to suggest 609. I've used this stuff extensively at work on servo drives, high speed packaging systems and other beasts that take a lot of beating. The problem is Loctite has hundreds of sealant / adhesive options some that may be better...

Looks like you are off to a nice build. Retasking the mill cabinet as a controls cabinet is smart. I might suggest putting that on casters too. Believe me in my old age I wish that I had spent more money on casters back in my younger days!!!!

I really don't think you can have too large of a capacity for a die filer. What you might run into is a lack of space that many of us suffer from. Generally the bigger "old iron" machines had a lot of mass and good balancing that allows them to run smoothly, that is a bigger deal that size

I look at it this way if you don't have an independent 4 jaw chuck now, you eventually will have a need. There are other approaches to mounting parts for eccentric turning but over all a 4 jaw is a very flexible solution. As for scroll chucks that is really a personal preference thing in my...

Please don’t give up before trying. Stainless can be extremely useful in the right situation. It isnt much different than trying to machine other alloys like 4340 that can work harden in a flash. So some general machining suggestions: 1. Cut your feet per minute by half vs what you would...

Interesting you should post this now, I just finished reading a few comments on these. Well the variant from Create Tool in China. Apparently Create Tool is a licensed maker of the unit. I’m on a cellphone at the moment so no links but I believe you can find videos on YouTube. In anyevent...

Harry I wish you all the best! I'm hoping to make it to retirement to have more time to devote to several interests my self. Last year in the shop at work, two guys didn't make it to retirement and that has had an impact on me. Thus I'm really wanting a way out (out of work not life) to...

Another possibility that fits in nicely with model engineering is to consider some of the powder cost systems out there. There are very low cost options to apply it and a repurposed oven can be used to cure. Unfortunately I haven't used such materials myself so any knowledge about durability...

Well some of this stuff is massive over reaction to sometimes questionable science. You feed a lab rat a constant diet of toxins and the rat will most certainly die. In the same regard alcohol can likewise be deadly if drank to excess but on average it can be seen as a positive by most...

You didn't define what is meant by small but frankly a Morse taper adapter to a ER collet is a very good way to handle smalls. I otherwise understand your situation, I have a generic 9x20 and the biggest problem with this lathe is in fact the screw on chuck. Back when i bought it I did some...

Hi guys; I noticed this thread a while back and two days ago received a flier from MSC in which a number of band saw blades are on sale. This includes bulk stock and pre welded bands. Look in all of their fliers as different brands show up in different fliers. Of course check carefully...

Entropy Lots of luck with the rotary phase converter build! As for some of the comments from various people about VFD's, I suspect many are misinformed about their reliability. We literally have hundreds of them at work on various 3 phase and single phase installations and for the most part...
