Lubricants

Postby Stanford Peverill » Thu Feb 11, 2016 9:40 pm

Hiya Made a few ash spindles with my new rounding planes recently and was wondering if there was a natural 'lubricant' to reduce the high squeak coming from the cutting process. Bit worried that the local residents or the local H&S officer with a meter will be knocking on my door. Thanks in anticipation.

Too much friction between turning part and tool. I have had a smoke curl up from rounding tools, just adjust cutting blade in a fraction.

A drop of linseed oil in the rounder.

Just a thought, if you have friction enough to make noise adding oil as a lubricant, maybe a fire risk?

Thanks for that after thought but I don't think I will be causing any sparks rouning spindles

its not sparks you have to mind, friction if the dowel is to tight, I have had smoke and the shavings turning black, so not far off combustion

I use wax, any wax from candle wax to furniture wax. I also can get high pitched noises without there being to much friction between wood and brass collar

In any cutting process the blade deforms the material being cut - I guess in this case the round spindle is 'relaxing' as it moves out from under the blade, and thus becoming tight in the guide - with a wooden rounding engine it is possible to relieve the internal diameter of the guide to reduce the contact area - not so possible with a modern all metal one... You need to lubricate the part that has been cut - how you do this with it inside the cutter is not going to be easy - any lubricant applied before hand will be removed in the cutting process... Some form of silicon or PTFE spray on the guide may help....

Be careful with silicon sprays etc, they interfere with any stain you may put onto the wood and some other finishes. I know that most furniture makes just do not have silicon in the workshop and never use it on tools that may come in contact with wood.
