Construction Day 8
|
|
This was a day of engineering with Paul. It stated at 10:00 lunch break 1:00 - 2:00 and finish at 16:00
|
|
|
First there had to be made an indexing
tool so that the wheel support blanks could be drill in similar
locations.
The was a large disc of still and the centre is removable in case it needs to be used for other operation. The blank was then placed on top and the first hole drills. The blank was then moved round and a peg put in the drilled hole and through into a previously drilled registration hole. In matter of an hours all the holes had been drill in all 16 wheel supports.

|
Here is a selection of tools and used to position as accurately the wheel support for welding etc. |
|
The set up for welding |
|
The tool shown above and the two blanks and the tube between now all welded up. |
|
All eight of the wheel supports welded up. |
|
Here is one of the wheel supports and the axel and bearings. |

Decided that the belt on the lathe
was at its end to-day. I cut through it and there was just a squiggy mess
- still had done great work since about 1975 when the lathe was bought.
The belt has been changed for what was once commonly know as "Brammer" this type of V-belt which is widely used in industrial and marine applications. Although more expensive than ordinary V belts it does have some important advantages: * It can be installed without having to dismantle the drive system and spend hours pulling apart well set-up or bedded-in components. * It helps to prevent a drive system reaching a resonance frequency and is recommended where the transmission of vibration from the motor or other sources is undesirable - in precision grinding machines and high-speed lathe spindles, for example. * It is of very high quality and claimed by the makers to have an improved shock-loading capacity and better abrasion, oil, chemical, damp and heat resistance in comparison with an ordinary V belt. * It fits all standard pulleys - there is no need to replace or modify the existing setup. The "A section belt" is used on my Boxford ME10 lathe, A-section 13mm (1/2") width across the top surface. If I get 31 years use of of this belting it will have done very well.
