Thanks Sam.

Best Wishes, David

Ok! armed with all this good advice, I'll make a start on pinion No.3 after 2 failed attempts. I ought to get some time in the workshop later this week.

David

Thanks Peter, that makes sense.

David

Thanks for the link Peter,

I noticed that he drilled the first side of the pinion with a twist drill and then carried on through the other side with a spade drill. What would this be for?

David

Thank you all, I'm happy that it's not only my incompetence that's the problem

There are some great ideas here for me to try.

Thanks again, David

Thanks Jeff,

I've not tried that but it's certainly worth a shot.

I did attempt a centre drill and also a spot drill but the indentation left by them was larger than the hole I am drilling so the benefit of a centre drill was lost.

David

Thanks John,

I'll check them.

David

Thanks Niko but I don't think that I'm up to sharpening a drill that small. Having said that, I could give it a go.

David

I’m having difficulty drilling a lantern pinion. The 0.030” diameter drill does have a tendency to wander.
Any thoughts on how to control it would be much appreciated.

David

Just in case you hadn't thought of this and, if I'm correct in thinking that you are more concerned with the end product rather than learning how to use the tools, have you though of approaching a local sheet metal shop and asking them to guillotine the strips? This would be much quicker, more accurate and the cost would be minimal.

David

What size pieces are you trying to cut?

David

Hello Iain, I've made 2 clocks from John Wilding ( with much assistance from the guys here ) and I'm currently making a third. Please feel free to contact me if I can help with anything.

A very tentative thought, would it be more accurate to mark out the holes on a much larger radius and then follow the radial lines towards the centre until the required diameter is met?

David

Glad to see you got there Mick

Ian Cobb is your man. PM me if you can’t find him.

Ah, sorry, it's the news that we are to revert to imperial measurements.

Good job that the DRO on my mill can switch to imperial!!!

David

At the risk of exhibiting my lack of understanding, I think that making a template in a rectangular frame then transferring the spacing to the circular frame might work.

David

It seems that I'm more fortunate than most as my workshop is in the cellar of the house. Even so, it's hitting 20c in the afternoon.

David

Oooo! cutting
