Dave Paterson.....I need your e mail details to send the plans

I have got a copy of an old article by Edgar Westbury for a vapourising spirit burner for internal flue boilers. If you think that it will be of use, PM me and we can arrange to have it e mailed to you.

Dias,,,,,plastic sounds good.....the previous owner of my lathe did a tremendous amount of damage which I did not recognise when I bought it and which subsequently cost me dearly. I am therefore a bit sensitive on this issue.

Clive....does soft aluminium snap cleanly and immediately if the worst were to happen?

Nigel B has mentioned an accident when a machine without a clutch/disengegement mechanism hit the stop and broke a roll pin. On my lathe (Warco 918) the only protection against such an accident is the "roll pin" in the end of the leadscrew, but what should this roll pin be made of to ensure that it breaks before any serious damage is done?

Mick

Interesting thread this one. Has anyone tried a similar conversion on a Warco WM14?

John S or Ketan.....just had a look at Arc Euro collet blocks and I notice that the collet nut is available separately. Does this nut have the same thread as the spin indexer? ( I have banjoed mine....don't ask how).

Terryd.....I think that what KWIL meant was that citric acid has been used by drug dealers to bulk out controlled drugs thereby making their already lucrative trade even more profitable. But thereagain drugs have been bulked out with everything from glucose powder to brick dust and there is no sign of these going under the counter. I must say that I find this self imposed, jobsworth type, petty regulation somewhat tiresome. I was once told by a Boots pharmacist that he could not sell me copper sulphate in case I was a terrorist (perhaps Pensioners' Liberation Army) and wanted to make a bomb with it !!!!!! At the same branch I had to do a covert deal "under the counter" to buy some hypodermic syringes after some interrogation as to whether I was a junkie. I bought some copper sulphate at a garden centre (can't say where in case the urban terrorists are tuned in) and got some extra syringes at a car boot sale (can't say where in case the junkies get in on it). Of course there is nothing illegal about buying these things which should be freely available. In fact if I were a junkie, needles and syringes are freely available at drop-in points.

Andy.....sorry, you have got the ports on the stand all wrong. If you google "Animated Engines-Oscillating Cylinder", you will see how they should be arranged.

Thanks for the response gents. What an amazing range at knockdown prices. I shall grab one by the weekend.

KWIL, thanks for the tip. Is the laser pointing such that it would focus on a dab of matt black paint on say, a copper component?

Mick

Can anyone recommend a means of measuring surface temperature of models and parts thereof in the home workshop. I am thinking of a variety of uses for the information eg which paint to use, where insulation is required, gas tanks and their location/specification etc. I have Googled and found that there are hand held point and read devices available in the £50-£100 range but I would appreciate comment from anyone who has had experience with them.

Dick....as previously mentioned there has been considerable discussion on this very subject by G1MRA members, including some of the apparent anomalies and inconsistencies mentioned on this site. It seems that the "official" line is as I posted earlier, although the discussions involved some who use 70/30. The obvious advantage of 70/30 is that the problem of freezing tanks and non gasification of butane is reduced. Others site the gas tank in the boiler feed water which tends to maintain a fairly constant temperature if the bypass is open. A liquid gas feed system is also in use and this also reduces the gasification problems. I have left you a PM.

Correction to above (wrong again)......G1MRA specify the use of a label on the tank stating butane only to be used and temperature of tank not to exceed 16C/60F. Tanks tested to 180psi. The subject has been done to death on the site but access requires membership.

There has been considerable discussion on this subject on the G1MRA (Gauge 1 Model Railway Association) site recently. I believe that they have decided  on a 360psi tank. It will take a bit of reading but I will have a look and come back if different.

Bob...there is a lot of overhang if the taper type is used in the lathe.
