After trying both methods, milling is a lot nicer than chemical etching.

Over the weekend I have bored out the bearing housings on the Monitor, started with drills then a single ended bar held in the chuck and the final cuts were done with a between ctrs bar.

The casting is too narrow to allow for the crank and bearing flanges so I back cut the sides to account for some of the flange width. Luckily there is an access cover on one side which allowed the tool to be adjusted within the crankcase

I then turned the outside of the liner which had previously been roughed out, the slight differences on the surface are due to the middle being wasted for clearance and the top end being 0.004" larger than the bottom

Hi Jason, got a bit confused for a moment or two, when reading your latest post. While spelling mistakes and misplaced letters are acceptable, it is funny sometimes how the odd one or two can change what one is trying to understand.

e.g.

" ... single ended bar held in the chuch ...." I read as, held in church. I'm sure the Vicar woundn't mind the odd demonstration, but probaly not on a Sunday morning. Rereading this you obviously ment chuck

".... the outsid eof te liner ...." This one I read as, outside end, but then the te didn't make sense. Rereading this you obviously ment outside of the.

Nice work by the way.

Regards Nick.

Thats what comes from rushing to complete a post when lunch is ready plus a bit of my dyslexia, I've edited it now so nobody else gets confused.

I finished adding a fine feed to the quill on my Myford VMC milling machine.

No more nudging the knee to get the right dimension and far nicer to use with a boring head.

A few more pictures are in the album showing the general arrangement.

Got a DRO for Christmas and fitted it a couple of weeks back, used it today for the first time drilling out 8 evenly spaced holes on a machine vice I'm making, I can only drill to the middle so when one side is done I flip the part over and drill from the other side, it turned out bang on the money the DRO's brilliant I see why people like them so much.

This is a poor picture but shows the DRO

The pictures are a bit crap but hope you can see how it turned out, really like the DRO.

Cheers Neil.

I looked at the Mini-Lathe hand wheel you made based on Graham Meek's design and you've spurred me on to do the same with my Mini-Lathe and also my Harrison - when time permits.

Learned that 12.5 degree swept-T joints for 110mm soil pipe are like hen's teeth. I've managed to fit in a standard T a bit higher, but I'm still not happy...

Also discovered that hammering 4.5" nails through studding, ceramic tiles, lath and plaster and into the joist behind works.

Knackered now, but still more timber to put up...

Someone on this forum mentioned using a radius milling cutter to turn a rad in the lathe.

Tried this first time today using R2 milling cutter. Result on this En24T turned out very satisfactory.

Ones side done with spindle in forward, the other in reverse.

Milling cutter was held in a 'Vee' tool holder intended for a round boring bar. Very quick and accurate method.

Beautiful work Blowlamp and Involute Curve, I am inspired to improve and match your skill.

Not model engineering nor what I did today, more case of what I have been doing the last 6 weeks.

I designed and built this bead roller which has a 4" throat depth and 24" throat length. It's to be used for making custom motor bike parts in particular tanks and fenders as well as panels for motor car restoration.

Guards remain the last piece of fabrication to do, then after testing strip down for painting.

Soon I can get back to model engineering.

Nigel, you can use that as an English wheel too. Good job on an essential piece of machinery in the custom fab business.

Today cut 6mm keyways in En24T bead roller dies, here's my set up which is similar to one I saw in MEW or ME many years ago, it's surprisingly robust and works very well, very happy with the result.

HobbyNut - thanks for your suggestion, the frame is very stiff so I think would it would be worth a try.

The Ford Diff was shortened by 37mm each side, it is a 9" with 3.55 gears.

This is how the car looked at 9.00pm last night. The body came back from the paint shop at midday yesterday. I have to get this finished so I can get back to smaller engineering projects!!

I started sorting out the problems with my brand new Warco GH1236 lathe. Long story. Might turn it into an article for MEW. On second thoughts the way its going I could probably run it as a serial.

Drilled and tapped the base casting of the S50 for the slidebars. Only a simple job to most of you but it took me all afternoon, most of which was lining it up on the mill.
