The Workshop Progress Thread (2017)

I'm going to have to keep a pile of sick bags handy if people keep posting wobbly workshop videos...

Or give away tripods as the prize for tip of the month!

Neil

Or put up plans so video makers have somewhere stable to put their camera.

Thought this would be useful. Not sure

I made a smaller version, with a Jacobs type chuck, about a month ago to replace a rather decrepit pin chuck.

Nice knurling, Benny, but [assuming it's meant to be hand-held] ... mine is on a small file handle, which I find very convenient.

Of course, yours may have a centre-drilling in the end, and be useful for other than hand-work ... I accept that the knurled shank may be optimum for the way you intend to use it.

The scrapyard press!

At long last I've finished my press. It's designed to press down (not the thrust bearing at the bottom)

And pull up.

My new spindle is shown in this example.

Hopefully, I will now be able to disassemble and reassemble the headstock without recourse to a hammer and I will instantly become a brilliant lather...

It's not pretty, but it should be able to squish stuff nicely!

Iain

Benny, it will be. I made a similar device using the spindle and chuck from a defunct Makita battery drill fitted to a wooden handle. Only took half an hour or so, very useful for holding small screws and pins for grinding or filing. Dave

JA, I actually made it to hold a countersink so that I could hand-deburr stuff, but as a pin chuck it would be great... why didnt I think of that?

Michael, I didnt have a file handle I felt I could spare so this was the easiest step, took maybe 15 min or so. But I am lost as to why a centerdrilled hole would be of use, what am I missing, a small chuck for turning between centers?

Dave, great!

.

Benny,

I was actually wondering if I had missed-a-trick regarding your design [although it appears not]: If the tail end of the handle was centre-drilled; the device could be used, with tailstock support, for 'sensitive' drilling & tapping.

MichaelG.

And I misunderstood your post Michael - I thought you were suggesting drilling all the way through the handle (and chuck) - to make a form of hollow hand vice...

They are not expensive to buy though...

Sorry ... I should perhaps have mentioned Slocombe

MichaelG.

I do not think mentioning either Mrs Slocombe or her cat would help.

Regards,

Richard.

Touché, Richard

... the e was superfluous

I should have written Slocomb

MichaelG.

Or superficial as Mrs Solcombe may have put it.

I decided to perform one of Steve's improvements as found on this website **LINK**. This amounted to turning a new pulley for the motor, this one is approximately 1" (25mm).

My particular version of the mini-lathe had a different setup for adjusting the belt tension, essentially there was no bracket at the end where the adjustment screw was, instead it was built into the plate, so I had to begin by milling away that material, making a flat on the top and two holes for mounting.

This is how the bracket turned out

Everything mounted and adjusted, now the max rpm for the low ratio is 600 and the max for the high ratio is 1200. Previously it was 1200 and 2400.

Looking forward to trying it out.

I made a start on the part completed Root & Van Dervoort vertical, generally assesing what still had to be done and making up some of the assorted fixings and small parts.

The crank shaft was going tight a TDC so I put one end in a collet upto the web and clocked the other end, 0.018" TIR so out came the precision tools to try and improve matters, no lead hammers here as mentioned in another thread. It is quite surprising how much "spring" there is in a bit of EN24 but it submitted in the end to the 18" Stilsons

There are quite a few square headed fixings, non standard nuts and some filaster headed screws so the 5C spin indexer got a fair bit of use.

Interesting optical illusion, to me it looks like the stilson is climbing up the cabinet!

Neil

Just to show that I do make stuff now and again, here's some pictures of the bogies for a new club riding truck

Good to see that even the experts need to resort to some "agricultural adjustments" when chasing that last few thou' of precision!!

Martin.

Started off having a clear up but got side tracked into a job that's wanted doing for over 2 years.

When I bought my big mill , a WM40 from Warco it came with a two axis DRO fitted but I swapped the 3 axis read head off my old mill onto this which was OK as I use a vernier type bar on the quill but I had a spare scale kicking about to fit so in the clean up, found and and started to fit it,

The only place to mount this was on the electrical cabinet at the side but as I guess although it looks square it's not plumb in both plane because of the column tapering so a lot of winding up and down and shimming before I was happy.

This mill has a three phase motor driving the knee directly which is one of the main reasons I bought it as it's the next size up to a standard Bridgeport but they had been very conservative in fitting the stops for the knee motor and I was loosing out at least 3" top and bottom under power although I still had this movement if I wound it by hand.

So a re measure and a bit of drilling and it stops just short of the physical stops. So 433mm on knee movement under power and can just scrape 450mm if I hand crank to the physical stops.

So all in all a productive day and we won't mention dropping a very large box of Coventry Dies and having to re-sort them all out off the floor.

I said we won't mention that bit.
