Delta Shaper Column Stuck

[Perry Bowen]

10 year old shaper that I use every week. In the past when the height adjustment did not move freely I would
blow out the dust and use 3 in 1 oil. Hopefully someone has had this issue and can offer advice. Thanks.

3 in 1 is a dust/dirt/grime magnet. It sounds like you need to clean the column. Afterwards use a dry lubricant. I prefer paraffin/Gulf wax. If you go that way apply it lightly and only when needed (don't over do it).
