Connecting the leads to a battery is ok, but the "regulator" will need to be moved to the run position. Apolgies if i'm stating the obvious.

Medissa shoes. Liversedge do a wide range of shoes in uncommon sizes. They don,t list AAA but may be able to help. Full details from their web site.

For many years I had an "Earlex" which worked well, when it dies I bought a " Karcher", which is awfull!. The main problem is that the Karcher has a pleated filter element which gets clogged very easily. The Earlex and similar models have a bag filter which the dust tends to fall of,f and therefore not clog.

I have tried to use both "screwmez" and the gear calculator, When I try to run them a box comes up saying I don't have permission, then my anti virus (Panda) says it is a dangerous program and removes it. My computer knowledge is very limited so to me, the programs are useless. I am using Windows 7.

Hi Anthony, I have sent you a PM.

I tried to use a speed reducer in conjunction with a pillar drill and a 50mm hole saw. I found that I could not hold the outer of the reducer - hence no drive to the hole saw.

David,

I have the same linisher, and have got 915 x 100 belts from Axminster, and cut them in half. It is a simple task to divide the width into two by cutting on the inside using a "Stanley" knife or similar. I made a simple jig to act as a guide. Even if not very neatly cut, they still work. I have found that if heavily scored, the belt wil break apart, but that may depend on the grade of belt. Whether the Axminster belts are strictly "metal cutting" I don't know, but I have found them satisfactory. There may well be other suppliers.

Axminster sell a "metal bender" which looks identical.

Gentelmen,

When time allows I have to cut a 16DP gear in SRBF. So far I have failed to find any useful information on the cutting speed that should be used and tool geometry. Should the tooth be cut in one pass? Any advice please.

Regards

John

Thankyou to all who replied to my question. In less than 24 hrs I have the information from several sources. All I have to do now is make a cutter, then a gear.

Gentelmen (and Ladies)

I am about to try making a replacement gear (16DP 14.5deg PA 56 teeth) and need first to make a suitable cutter. I have read Ivan Laws book, and obtained an excel spread sheet giving sizes for the buttons and their spacing for 14.5 deg, from a kind Gent via the internet. However in a quest to actually understand what I am doing, I would like to know how the button cutter spacing and infeed is derived. I can work out the size of the button cutters, but the spacing and infeed have eluded me. Can anyone enlighten me please?

The chuck is tightened by the front collar holds and the tap shank. The square of the tap shank fits into what may be described as a vice, tightened by the allen key socket, marked "open", and stops the tap rotating in the chuck. The "vice" is self centreing. I have one of these devices and it works well. particularly on the larger taps, just make sure that the morse taper is a good fit in the tailstock. I have not found it necessary to use the C spanner, hand tight seems to be sufficient.

John
