Plus one for Halfords clear lacquer.

as most news are nickel plated a lot of glues don't grip too well what I have done in the past is to bore a close fitting recess and fit the magnet then distort the edges slightly as the mags have slightly rounded edges.

Arc euro or your local bearing supplier

My S7 has a notch cut out of the pulley to make it easier to lubricate.

.Not trying to upset anyone but I find the heavy cuts and feed rates for carbide not always true, I use ccmt060204 and dcmt and rcmt inserts both standard and polished and find fine cuts just as successful as deep ones. On the question of boring in the mill it’s possible to rotate the boring bar in the head where on the lathe the boring bar has a flat on it giving positive location could that be part of the problem?

One of the big problems with a lot of commercial coax indicators is the amount of headroom required so if you have a small mill they can be impossible to use which is why I when the route of making my own. A nice satisfying project which gets used again and again.

Surely it’s a coaxial indicator by another name?

I remember that item in Parks Pumps in Norwich from the 60s and 70s and if I remember correctly it was made for FERODO.

you could try masking with Snopake (red) and then the silver solder will build up not run all over the place.

The devil lies in the two words Qualified and Competent. I personally have not seen the word qualified in the lit I have read.

to find the TPI lay against a imperial rule and with a mag glass check tooth count over a known distance and if say 1/4' was used multiple by 4 =TPI. if pulleys are cast odds on they will be Whit.

get a genuine one from Steve at home and workshop machinery mines absolutely spot on.

Don't know much about push bikes but was fortunate to live near Mike Burrows of cycle fame and see some of his recumbent creations. he was once caught speeding in a 50 limit on one!

I am quite surprised when people say cut aluminium dry with hss or carbide I have found that you can can get cold welding on the tip of the tool and the finish is not as good as when a splash of WD/Para is applied and still not as good as when using PCD tips there Bl***y marvellous , its a shame to touch your work afterwards!

Speedy builder, I am going the same route but with 500watts and using a lot of ideas from DAG Browns injector book. It really needs a method of switching when up to WP to make the thing useful so injector tests can be done without having to keep an eye on that part of the job.

If you used delrin/acetal you could glue the blank onto a steel mandrel then machine your piece and part off so you then have a heavier playing piece.

Mike, Take it out carefully with an adjustable reamer.

Yes you can they have a cone arrangement for adjustment they are used on boat propshafts.

well done nice job.

Have been to Waterford Crystal several times and was assured that all glass is in house!
