Timmeh's Workshop.

1/2" centres on the outer legs, 3/4" centres on the inner gives me 1/4" increments.
Smallest setting is about 500mm x 280mm, largest 1800mm x 600, yet to be confirmed. Still need to work on width capacity... Another day...
First "production" run for the $50 bunning's clearance item drill press. Motor got fairly warm drilling 180 holes.

Pondering measurements, methods and procedure's for the x/y vise and screw jack/riser frame, for the leader lathe(haven't forgotten, just temporarily on hold) has lead me to a few more side lined projects.
An old tool chest scored at a kerbside rubbish collection. Had the plastic top tray for ratchet/socket set, handful of sockets and various other broken/rusty tool remains, must be 25 years ago now.
Slowly cleaned, derusted, lubed and improved whilst maintaining the "look", that being "who in their right mind would want to steal it", it's the travel tool box, the one that gets tossed in the car for call outs.
Some angle brackets to support the tray, heavy duty handles(it got a bit heavy for the top handle and more importantly the lid).
All fasteners, materials, brackets and handles are recycled.

El Cheapo floor/trolley jack, purchased around 1996, near new second hand, with issues (price was right), fixed and into service. It did nearly 25 years of hard labour before the check ball in the lift cylinder got stuck under the copper seal/flange/washer.
Fixed again, back in service.
Never had one of the carry handles on this one, must make one. That should do just nicely...

 

[timmeh]

Couple more jacks to fix.
Red one 5 tonne, disintegrated seal in pump cylinder.
Yellow one unknown as yet, low on oil, bit of corrosion at top of ram.
The little bit of research I've done to calculate output on the yellow one has got me having another look at the trolley jack's ram and it's actual output, I mean it has 2000kg capacity at the lift point. Looking(just looking, no calculations) at the lever/frame that the ram actuates, the actual output for the ram must be 2.5-3 times greater than the jack.
That trolley jack may get repurposed as I have another, bigger one, that needs a little work.... More on that later.

Righto, bin a bizzy lad 2day. Here goes.

3-10, the bottle jack of unknown capacity.
11 comparing 5 tonne with trolley/floor Jack.

For the non believers, yes its done. More tomorrow.

Few more of set up, 100 rpm, haven't checked what the feed rate was, just threw as many gears on as would fit.
One harder spot in the casting along one side, few more progressively lighter cuts till it stopped deflecting the tool.
May need a little scraping done.
Got a handful of videos of that setup running, will post a few on YouTube.

 

[timmeh]

Got a little sidetracked again, drill press problems, more on that later.
Here is line boring the "handle" for the trolley jack, still needs some trimming and fettling to finish.

timmeh,
You are one creative machinist!!
I enjoyed the ride.

Oops, I broke it. Using the 3D printed sleeve and double keyed hub, I forgot to use lube and a lock nut on the mounting bolt.
Stripped the 16 tooth compound gear completely.
Welded sleeve to hub to bolt, had to use the press(no pic as 3 hands required) to get it half way out.
Gets a bit tricky now, need to rig up some gogo gadget arms.
