Sadly I'm just a hair over six feet tall, rather short for my family. I blame that on too many broken bones growing up. Actually my problem isn't length but rather width, most 15 4E shoes are just too narrow for my feet these days. Often it is easier to buy a size 16 shoe as they will be a...

That would depend upon your lathe as you note. You can get a shallow taper mechanics like this to work on any lathe if you are willing to go through the mechanical design effort. There are a number of tapers though that would benefit from accurate feed rates on the compound which brings us...

Hey glitter is important to young girls. AS for the distraction of making machine modifications, fixtures and such; for many that is part of the journey into model engineering. For some it becomes the main focus of the hobby. Your interest in a drive assembly for the compound slide is not...

Nice work guys! You appear to be having lots of fun There are a number of projects putting or trying to put GRBL on 32 bit ARM. Development seems to have slowed up a lot. I believe that this is due in part to one of the main developers trying to rewrite major portions of GRBL for a bright...

A few suggestions: 1. If you are entirely new to this don’t commit to one CAD/CAM package immediately. Try a few instead as they all are slightly different and as a result may fit your needs better or your work habits. 2. Sometimes it can be worthwhile to use process specific software...

Actually your picture kinda explains exactly what I’m saying, the middle of that machine has arecessed panel. That is due to human factors, especially for back in the day when machinist spent all day in front of the machine. That panel arraingement May only give you six inches of clearance...

Go to the dollar store and buy the super glue intge tiny tube sets. You get four tiny tubes, use them once and throw out the left overs if any.

There are a number of different archetecture you could build for a DC motor controller. Probably best to search some electronic hobbyist sites. It is also likely not to be cost effective when SCR type controllers are so cheap.

I think you need to give people time to actually visit the site, especially over a holiday. If you mean the compound and not the cross slide this is very doable. I would likely choose a stepper instead of a servo, mainly for compactness. The biggest problem is that you will need to...

Just a bit of an update, I had one corner of my shop basement with either no lighting at all or one four foot fluorescent fixture. Needless to say that corner was dark! This summer I got funds together to upgrade the lighting in this corner. What I went with was Lithonia Lighting’s “7”...

There is nothing wrong from the rigidity standpoint, these tool boxes should be fine inthat regard. What may be a problem are human factors considerations. There are two issues here. The first is will the lathe be at the right hieght for you. This is different if you sit or stand at...

Self tapping screws in my opinion are only good for holding sheet metal on a barn. I would not use them to many fine model or even a machine tool. This is prett much repeating what has already been said but here are my suggestions. 1. Buy quality HSS taps. If not HSS the new super...

A little late but I’m glad to see you have things to your liking. Squaring up a machine can be very tedious work. In my younger days I work as a mechanics helper in a machine tool rebuilding operation. Everything was aligned by hand scrapping surfaces in, extremely tedious work. It could...

Jen. I feel your pain we are seeing similar problems with quality control in the USA. You either pay big bucks or gamble. A couple of years ago I purchased a small set of Silver & Demming drills and had one that chipped the cutting edge way too easy. Went to put a new edge on it and got...

If I got handed such a nice piece of material I might trade it for better tools. I really understand his point though, this isnt industry, you goal isn’t maximum speed/production so calculations to reach those values don’t make sense. This especially in the common materials found in the home...

Jenny I feel your pain. Here in the USA we went through a couple of drill suppliers (at work) that couldn’t ship drills that actually would drill a hole. This was for standard fractional size drills supposedly produced in the USA. I suspect that some of these manufactures believe the drill...

That price is actually pretty good. You need to realize that these are high quality devices made out of good steel and treated properly. You can make your own of course but buying tool steel will quickly explain part of the cost for these holders. For the home shop you don’t need tool...

Feedrate is a significant component in getting good results, I'm glad you pointed this out. Just yesterday at work I was trying to machine a bit of work hardening steel and had a feedrate that was too slow leading to work hardening and really ugly cutter behavior. A simple change in...

On my 9x20 I actually remove the compound for a quick change tool post mounted on a block. The support block bolts to the cross slide. Obviously tapers can not be done with this approach. But a bit of planning and a selection of cutters will solve that problem.

Guys, one of the bigger factors in successfulrunning of a VFD on single phase is the size of the input rectifier. Obviously single phase currents are much higher for a given amount of motor power so the rectifier needs to be able to handle this extra current. This is where talking to an...
