Mini Lathe Lever Locking Tailstock Upgrade

G'day,
As a lot of you will know, I speak very highly of these little mini lathes. For the price and size, they can really punch above their weight. One thing I have been meaning to upgrade for a very long time is the tailstock locking mechanism. This does not apply to all mini lathes, but it seems to be very common for sieg branded models to have a nut locking design on the tailstock, rather than an eccentric locking lever. The nut can be very difficult to reach due to the limited space on the lathe and the time spent undoing it can really add up if you are doing a job where you need to make frequent use of the tailstock.
Today I will be upgrading the tailstock to have a lever locking system/lever lock. I will be making use of my mini lathe, and my new mini vertical mill. I will also be replacing the locking plate and stud.
Cheers
Lathe: Sieg c3 7x14 mini metal lathe
Lathe 2: Sherline 4410 CNC
Vertical Mill: Sieg x2.7l
CAD: Solidworks 2018

Seriously, this man needs a band saw or a power hack saw. Even if it's a Harbor Freight portable power band saw on sale for $99. You can make a stand for them and hold them in a vise or make a stand and have it pivot. Anything has to be better than flailing away that long with a hack saw. GET A BAND SAW MY MAN!

It drives me crazy every time I see him hacksawing something. Sometimes I think he does it that way deliberately. Now that he removed metal from the bottom of the tail stock, without shims, it’s likely lower than it should be by a thou or more.

@@bustednuckles2 "HF portable pbs" yeah, I wouldn't go beyond that with china junk, my pulley ate itself due to bad design, now I just use table saw or chopsaw, loads of carbide options nowadays.

@artisanmakes 2 жыл бұрын

Although I did not measure it, scraping would remove tenths, not thousands, or as i'd put it microns. I removed less material than I could shim for. Cheers. And I do not have a band saw capable of cutting metal.

I glue sandpaper to a $40 granite block then flattened my cross slide, compound etc. Once flat I glued sandpaper to the bottom of the cross slide, compound etc and put them back on with "semi" tensioned gibs and proceeded to work them back and forth. My cross slide went from impossible to adjust without being sloppy somewhere in the travel to set and forget.

@michaellinahan7740 2 жыл бұрын

as a C6 (Hare Forbes special) owner a tail stock lock arm was one of the first improvements after making a riser block and removing the compound slide (I have only used it a couple of times in the last year). However, I did it by first drilling through the web of the tailstock (front to back) then using a digital angle block to find the draft angle and machining a spacer for original bolt hole and new hole in the web. I then made a thick walled tube for the slug connected to the draw bolt to move up and down in. This gives support for the rotating bolt with eccentric machined as you did. The only other thing I did was to put a thrust bearing between the collar and brass spacer on the back. (incidentally I also have a thrust bearing under the locking nut on the QCTP) These are sturdy machines if you accept their limitations and use a work around when necessary.

Thank you for posting this. It's a great idea. For someone to duplicate it however, would almost require designing it from scratch, as all of your shots are very close up and it's difficult to tell if what we are looking at is right side up or upside down, front side or backside. As well, the final assembly isn't shown in a way that we can see how it goes together and how the parts work together. If your goal is to help others to duplicate your work, consider these thoughts and posting some drawings, exploded views, etc. Thanks

I ended up buying the kit from little machine shop. Not cheap when you factor in shipping from the US (ended up costing me best part of £50 sterling) but when I factored in the time & cost of materials (none of which I had in stock) it was the sensible option. I use my mini lathe in my business, & although I’ve managed with the nut & bolt for over a year, I really like the cam lock, plus it means my stubby 17mm combination spanner can go back in the set.

That kit from Little Machine Shop was one of the first mods I did to my mini-lathe. Then made a nice knurled handle to replace the round plastic ball on the lever.

Cheers Joe. The CAD software that I use is Solidworks, and to a lesser extent nowadays CATIA and Autocad. Everyone has their own favorite, the most popular one for hobbyists is Autodesk Fusion 360 which is free and easier to learn. There are some decent tutorials online for fusion and it is great because it supports g-code generating, incase you ever CNC your mill or lathe. Cheers

Hey Artisan Makes. I just got myself a lathe and was hoping you might have some insight. I am chasing a few bits and pieces for my lathe. Where do you get your tooling? And any recommendations on brand of centre drills and taps and dies? My first project is adapting a quick change tool post to my lathe and if possible want to get my tooling local.

@trailxrage 2 жыл бұрын

@artisanmakes 2 жыл бұрын

Most of my lathe tooling is either from ebay or made here in the workshop. I have a few bits and pieces from hare and forbes, and I always pick it up in person because I like to see what I am buying, although tooling from there is expensive, albeit good quality. My centre drills are just cheapo ones from ebay, they do a fine enough job and have lasted me since 2019. For taps, I use an old frost tap set (though having used several brands over the years I cant tell too much of a difference between brands), but if I was starting out new i'd get each tap as I needed them, rather than paying for a set. The rest of my tooling is either stuff that has been used by my family for years, or stuff I can pick up from bunnings. As a hobby machinist on a budget, bunnings and ebay tools do the job just fine. Cheers

@trailxrage 2 жыл бұрын

@@artisanmakes Thank you for the insight. I am also on a budget so appreciate your tips. Looks like a bunnigs trip is on the cards. I had one other question. Where do you get your tool steel? Like you I tried turning down some all thread to make a shaft, but the metal is horrible.

@Chrispruitt83 2 жыл бұрын

Hello Artisan, I notice in a lot of your videos you do mods/upgrades that stress the end result of saving extra time that's otherwise wasted. Have you considered investing in a machine (jigsaw, bandsaw, portable bandsaw, metal cutting saw, etc) that would greatly speed up the process of cutting your stock materials as opposed to doing so by hand. Love the videos by the way!

@artisanmakes 2 жыл бұрын

In the grand scheme of things, stock cutting with a hack saw really doesn't take as long as one might assume

Plans? or is it DIY? what if you made another mini lathe using the mini mill also, then CNC'd it with Arduino, that would be the cheapest CNC mini lathe possible..similar to Levsha's Taig micro conversion with Arduino..

If you want to see what can be done to a mini lathe and a scraper check out Rotary smp channel ! That above all else is the thing I detest most about my mini lathe - the tailstock! Even with a lever lock fitted I still hate it and adjusting it so the machine turns parallel is a Pia ! Mine will soon be converted to a dedicated grinding machine .
