Hello Dave,

Not difficult to chat to my GP as he is a neighbour!

Andrew.

I think it depends on the lathe. I refurbished a 920 lathe for a disabled friend. The design is poor and there is a lot of potential tool movement because of an inadequate base. Even doing one of the standard mods to overcome this, still doesn't give a really firm tool. I took off the topslide and made a "Gibralter" tool mount. That made a huge difference. You can still remove this and reinstate the topslide for the odd time it is needed,

Maybe your lathe is sturdier than the 920, but even so your idea is to be recommended. I very rarely have need to use the topslide anyway.

Andrew,

Thanks everyone,

Looks as though it is indeed an "A" size. I even had Kempes yearbook in front of me when I typed out the query. As for Mark's comment about being any size, I seriously doubt this. I must have seen a few hundred Picador pulleys over the years and they have all been the same belt size. I think that Swarf Mostly is correct in saying other sizes were branded Pelican.

Anyway all is sorted and I checked an "A" belt on the pulley and it is the correct fit. I don't think I was too good this morning, otherwise I would never have asked such a question. Maybe I should have a chat with my GP.

Thanks everyone,

Andrew.

Having a case of brain fade today. I have a 2" Picador pulley, for which I need a V belt. Cannot for the life of me find this simple info!

I seem to remember that the belts are an "A "cross section, is this correct?

Thanks,

Andrew.

I have learned my lesson about dumping things. As soon as it dumped I find I need it in a few weeks time.

Andrew.

I second that. ARC's Chinese chuks are as good as an ordinary PB chuck. They stand up to a lot of work, without any distress.

Andrew.

I really don't know why people bother to get involved with this guy.

Andrew.

I have quite a few hand rivet guns, from el cheapo to fairly expensive. None of them are particularly good. I struggle with stainless rivets, even my 2 feet, long handle ones exhaust me!

Next time it will be lazy tongs and blow the expense.

Andrew.

Hello ega,

Yes I have the same problem with weight increase. I wonder what causes it? As for oil changes, I am still on the original oil.

Andrew.

Do you mean Spalding fasteners? If so, they have countersunk socket screws for 93 pence. They are 1.5 inches long so you need a hacksaw.

Andrew.

I have had an Oxford oil cooled arc welder for nigh on fifty years. No problems like duty cycles and nothing to go wrong, beats all the modern stuff.

Andrew.

I have several slide rules and still use them. I find it quicker than using a calculator.

Andrew.

Granted one could easily make a replica firearm with a 3D printer. However a real firearm is a whole different ball game. I would not want to pull the trigger of such an offering as it would likely do far more damage to me, than to any potential target.

Yes I know real plastic guns exist, but they are hardly in the same league as something made on a home 3D printer.

Andrew.

Hi Pete,

I would like the Mitutoyo vernier if still available. I will PM you with my details etc.

Regards,

Andrew.

I think they must be sintered as they are definitely steel. Extrusion would be perhaps far too expensive for such a low cost lathe.

I was just about to start fabricating them when Tony kindly offered me the bushes he has. I have already made the shafts and with due deference to the good finish on the new bushes I will case harden the shafts. Should last a long time, hopefully.

Thanks to all, especially Tony,

Andrew.

Thanks Mike,

I think that the system was having a senior moment. I was logged in and no sign of contact detail (I did scroll to the bottom of the page too!)

I then logged out and logged in again and there were the contact details. Gremlins perhaps?

Andrew.

Could Pete, who is advertising a Mitutoyo head , in the for sale list, please contact me. You don't have contact details in your ad. A PM will do.

Hello Tony,

They are indeed the bushes that I am after. A picture is much better than my poor description! I will send you a PM.

Thanks everyone.

Andrew.

I often use interrupted cuts. As long as the set up is rigid, then it works well. I use carbide tips on every interrupted cut job. This will get through any hard spots on a casting and no, I have never broken a carbide tip when doing this.

I think some of the accepted wisdom is that interrupted cuts are the work of the devil, I have never understood why.

Andrew.
