Re: Traditional ways of tying cables together.
Can you explain why RR would used lacing on Trent 700s and sheathing on other Trents, please?

Re: Traditional ways of tying cables together.
It has always been so (unless the looms have changed on the 700 very recently). The 700 happens to be an old engine, the oldest Trent still in production. If it ain't broke.... especially in aero engines where changing anything takes an awful lot of effort and money once an engine is certified.

Re: Traditional ways of tying cables together.
We were taught to use marline hitches in waxed linen tying at Bell-Fruit in the 1970's. It always looked so very neat, especially when performed by an experienced hand!

Re: Traditional ways of tying cables together.
Thanks again for all the inputs to this topic, I have found it very useful and I hope others who perhaps weren't trained in the Telco industry or Military might find it useful on their restoration projects.

Re: Traditional ways of tying cables together.
As well as Argus25 comments on sensitive cables run in a cableform, it is also wise to not run any mains AC side cables in a loom with secondary side cables. Similar to modern cable ducts in industrial equipment, its sometimes mandated to use separate ducts.
On that score, I have 'pulled' out cables in vintage instrumentation, and both smiled when pulling was 'easy', and sworn profusely when not so easy. That suggests it can be better to avoid 'really tight' lacing. |

Re: Traditional ways of tying cables together.
Chris, if you PM me your address, I'll send you some lengths of the various cords already mentioned in an envelope. Try them out, and see what suits your needs. The armed forces, the BBC, AVO, GPO, Marconi, & so on all had at times different knotting methods. Best bet is to find a kind Forum guy near you who can instruct you "hands on". It not really something that can be learnt by watching online videos, or reading the memories of us old hands via this Forum. Lacing a straight loom is easy enough, but bends & lateral spurs can be difficult.
Regards, David PS. Belay that first pipe, Chris, I already have your address. |
