Thread: Forgotten engineering techniques

You still get that in sandwich shops in sheffield

Called a dripping cake

Breadcake/bap/roll spread with either white fat or brown fat and salted

or you can have a hot pork sandwich "dipped" in molten pork fat rather than butter

Thread: Warco WM18 Power X Feed?

Added to post

mines a RDG version of the wm18 (weiss mill)

Axi now want 299 for the powerfeed but I still think thats worthwhile as its almost plug and play

Just the plate some spacers bolts and a coupling

the coupling screws onto where the handwheel was.... then locked by a grubscrew this sets the end float on the shaft

Remember to remove the handle off the opposite end ( out of balance when feed is going fast !!! ) leave the wheel though

In operation I use the switch on top to start and stop the motion rather than as standard the sitch on the speed control pot....just remove wires from switch and bring them out to new switch on top....you can also jog by moving switch not all the way.

at the end of the pas you have to switch off move the handle to opposite sense ( left right) then switch back on

just moving the handle to opposite causes an error

the limit switches would fit easily with the seig brackets but I dont use them as i dont leave the mill going by itself

dsc01369 (medium).jpgI fitted a axminster seig power drive that was on offer for about £200 IIRC

some photos here

simple fix

dsc01368 (medium).jpg

The part on the coupling between drive and bed is a quick release for if i wanted to use the manual handle in actual fact it overruns easily so I neednt have bothered

I've had it fitted 3 years of so and it works fine

 

I fitted the switch box on top so the feeding speed stays put as original switch was on the back of the pot so you had to start it from zero every time

the "bed goes" is just a memory jogger

img_7368 (medium).jpgimg_7367 (medium).jpgHeres a pic of the locking mech

Its ( on my lathe a mk1.5 )

The nut is 15mm dia where it slides into the saddle 28mm long

the big end is 35mm dia 10mm thick with one side cut flush with the 15mm dia bit

the opposite side overhangs by 6mm which engages on the bed slideway

the 2 pins are to stop it rotating

The bolt is 58mm long under the washer

obviously all dimensions would be imperial

Is there a pic on lathes of a non gearbox student?

What model student do you have? mk1 1.5 or 2 ?

The clamp to lock the saddle is on the top on the right hand side with a square head

No way engaging that should also engage lead screw

Not sure which collar you are adjusting to give you a different speed

you can disengage lead screw by putting imp/metric lever into neutral

you cant disengage lead shaft unless you remove gears

I would replace the motor and fit an inverter as one... motors about £130 ish new inverter about £200 new

But it looks in good condition and is as well tooled as you can expect

06/01/2015 09:32:48

No conection with the seller but theres a nice looking colchester student Mk2 on ebay in welwyn garden city

well tooled and fitted with a 2 speed motor mentions 4 jaw chuck but not visible in photos

If you only have single phase then have / fit yourself an inverter

bidding at £1500 BIN at 2200

you would probably get it for £1500-1700

Thread: Making tommy bars
12/11/2014 10:13:08

Hello all

I have a quick job to make some tommy bars for machine adjusting

They are 8mm dia with ends reduced to 6 at one end and 4mm at other

ends are 24mm long reduced size

total length is 150mm

whats the best material to use and any heat treatment that i can do to make them tough against breaking or bending?

Thread: What did you do today? (2014)
07/11/2014 16:33:06

dsc02772 (medium).jpgdsc02767 (medium).jpgToday was a bit slow work wise so I set too and made some microscope lens mounts these are threaded 24mm 0.75mm pitch so an exercise in threading first

brass bar 40mm turn to finished dia of 38mm then bore out to minor diameter

set up 60 degree cutter and cut about 40 mm of material enough for 5 mounts

Finished the end and parted off about 1mm overlength repeat 5 times

cut a threaded mandrel to reverse mount them to finish the other side

then transfer to mill to machine the dovetails

all work perfectly just need to decide what sort of handle to put on them

the chrome on in the pics is an original zeiss one to copy

fairly pricey if you can find them

Thread: Grinding lathe chuck jaws
06/11/2014 22:01:17

I recently have done this on a pratt chuck which was in fantastic condition BUT one jaw was of a different set

so after measuring i gently ground off a little of the offending jaw (with a powerfile ) till the whole chuck was running true To less than 1 thou now rather than 15thou before... this on a 30mm shaft of silver steel...very pleased with the outcome.

I probably ground and tested 10 times so very gently does it
