This article is about shortening a continuous hand chain on a chain block and shortening must not be done this way on a load chain under any circumstances as this would be very dangerous. To shorten a load chain the hook is removed the chain is then cut to the required length then the hook is replaced it is making it longer that you must not do.
The concept and history
Photo 1 show the finished article, actually this is not the one that is described in this article, it is one I made earlier. After sorting out and moving things in the workshop I found a feed bag with my chain block in it, I open the bag to find to my shame that both the chains, load and hand chain, had some rust on them. The rust most likely accrued in winter when the temperature changes from cold to hot in a very short time causing condensation in the bag, as it was stored in unheated building – well this is my defence.
To clean them up I was going to use a Citric acid and water bath this required the chains to be removed from the block. The hand chain was removed first it seamed long. I remembered that when I used the block the last time to put the Mill/Drill on its stand the hand chain was too long and getting in the way as it piled up on the floor but in the rush to use the new toy the block was put away and forgotten about. The answer to this problem was to make the chain shorter before cleaning the chain as there was no point in cleaning the bit that was not required.
