So, sanding sealer is 1/3 shellac with 2/3 denatured alcohol. Thank you, I really appreciate your effort, my English is a little poor.
Bill you are right . No lacquer over oil, but you can shellac over oil and then lacquer. Probably not the most long lived finish, but will stick. As to the original question of how to make sanding sealer, lets leave the sanding off as sealer is what you want and the sanding should be completed before finishing starts. Sealer can be either a 50/50 mix of thinner and the finish you will use or the universal sealer.......Shellac. Also with shellac by using different grades of Super Blonde, Blonde, Garnet you will get different shades. Garnet is very good to even out the color of cherry and gives a nice reddish tint to walnut.My opinion about lubricating sandpaper with oil when sanding wood is that it just masks sanding scratches and dulls the figure in the wood. The sludge of oil and wood dust and oil packs the pores and helps to mask fine scratches and seems like it also reduces the effectiveness of the sandpaper because of clogging.
It is good that you are concerned about breathing dust because it is a real health hazard. I think that there are a number of effective ways of dealing with wood dust. Wearing a dust mask or respirator is something that you ought to be doing anyway while turning. Using a dust collector or shop vac funnel near the work while sanding also help a lot in capturing dust. A fan at your back also helps. I sand outdoors so that I don't have to contend with a dusty environment in the shop.
Varnish over oil gives a nice finish, but I would allow sufficient time for the oil to cure. For walnut oil this means a month or two. Tung oil is also slow drying and might take several weeks. I would be hesitant to put lacquer over oil. Anyway, this is just my option on finishing and not the last word. Woodturners are forever experimenting with various ways to finish their work.
