What Did You Do Today (2016)

To be strictly accurate what I did yesterday was make a new crankshaft for my ST engine. SWMBO managed to knock it off the chest of drawers where it has resided for a long time, fell about 3 feet to the floor and bent the crankshaft. Tried straightening, no good. It was flycranks loctited to bar, so not actually that bad, but don't tell the domestic authorities!

I made a gland for the cylinder of my ST beam engine , turned out OK

Hi, not strictly ME as it is an operation that I made easier at work, yesterday after cutting 208 pieces of 12mm BMS 35mm long, they then needed to be de-burred at both ends. In previous times when I've done this job, it has been done on a belt sander, but they are a bit short and awkward to hold, so I used a battery drill, but this method tore the belt and I had to put a new one on when I'd finished.

Yesterday I decided to used a 4 1/2" angle grinder, so I made up a piece of 5mm plate with a couple of pieces of 30mm x 5mm flat bar with a hole in each to match the handle threaded holes on each side of the grinder, I then attached them to the grinder and then tacked and welded them to the 5mm plate. When the welds had cooled, I reattached the grinder and clamped the plate down onto my work bench.

I could the use half worn flap discs to de-burr each end while holding them in a battery drill. of course caution had to be used as the grinder was set going continuously.

I got through a couple of used flap discs, as it's a bit harsh on these as they tend to make a bit of a groove in them.

208 pegs de-burred ready for welding onto bars.

If anyone copies this idea please use caution during use. A guard could be made to cover most of the flap wheel to make it safer to use, but the operation of de-burring these pegs was certainly made shorter by this method.

Regards Nick.

Nick, that works for me!

In fact, I think I know what I'm doing tomorrow, as that will work well on my Workmate when working outside.

(another one)

Here's a shocking idea I came up with a couple of days ago!

Time to replace those power feed gears I did a nasty to in the BH600G's Apron.

Proof that I am, taken yesterday:

Taking videos of proceedings, but one of my Kodak camcorders went belly-up emulating what the company did, but thankfully after recording was done.

Anyone notice anything different?

Geoff - Too cold in the Carport to work on the Austin Seven.

Michael,

Very remiss of me.

Welcome back!

My brother had a quadruple done October 2002 and never looked back.

Your Workshop now beckons

Geoff - Mine as well, so I'm off.

Super 75th birthday party (mine) yesterday lasted into this morning (just)! Had hoped for cash presents to put towards quick-change toolpost, but never mind - got plenty of malt whisky instead, plus some other useful but non-workshop kit. Awoke this morning to see snow laying here in N. Scotland - real winter's here at last!

.

Thanks, Geoff

Workshop; Driving; etc. are all beckoning like mad ... But strictly off-limits for a few more weeks. ... First Physio/Rehab session is booked for 01-March.

There is understandably great enthusiasm for this 'cart-wheel' ... but, what intrigues me is the offset hole.

Engineering theories please !!

MichaelG.

Machined on a Sooper - Sooper Adapt ?

Maybe they were more sophisticated than assumed........ perhaps the offset hole is to impart a churning effect on the milk to produce butter on the journey home....... ( Always nice to have some butter and Marmite on the toast).

First record of wheel balancing.

Those early horses were fast!

John

The hole looks very crisp compared to the rest of the wheel so may not be as old

Either that or its for quatering as in when the enemy was hung, drawn and quatered

.

Much closer to my initial thought, Jason

... it looked rather like a locomotive driving wheel

"There is understandably great enthusiasm for this 'cart-wheel' ... but, what intrigues me is the offset hole."

I understand the hole was drilled by a Geologist taking a core sample before the wheel had been uncovered. He didn't seem to recognise bits of wood in his core!

Regarding using the angle grinder mounted on a home made jig, I have a very similar arrangement. Realising the possible dangers, I obtained a substantially made foot operated pedal switch . I wired up an un switched 13 amp metal clad socket outlet fitted with a neon indicator such that when the pedal is depressed the switch closes, the neon is illuminated and electrical power is then applied to the LIVE pin of the socket outlet. The angle grinder connects into the socket outlet in the usual manner. When I step on the pedal the grinder works as normal, the pedal and socket outlet are both mounted on a substancial piece of wood. Should any thing go awry or amiss ,I just walk away. Fortunately that has never happened. John

Just made a 22mm Mild steel peg with MT2 taper for my mill mounted rotary table chuck, i used a few slips of paper to improve the fit. fitted the tee slot studs thru the chuck and dailed it up on a Baty 0-10mm plunger type indicator.

was reading a runout of 0.28 and i clamped down one of the three tee nuts, through rotating and carefully tapping either side with a plastic mallet and then rotating it again and again, i was able to bring the run out to 0.02, this is good enough for my general work, very pleased with the quality and rigid setup of the dial.

It will certainly stop my hole patterns from wandering off, it just goes to show you dont need sophisticated equipment to sort this type of problem out, just to be a little careful and only tapping the mallet til it reads half its value to 0 on the gauge. I suppose i couldve made a better fitting plug but i wouldve needed to dial it up anyway, i didnt want to push my luck to 0 runout because my wrist is aching from slowly rotating the 4" chuck on its worm gear :P

As its a single wheel and its partner has not been found or an axle, it was not for a cart. No, it was rotated by a lady called Susan to offer food to different guests sitting around it..

Frank

Perhaps it was a 'skinny' spare wheel!
