 Poster: A snowHead
|
Probably one for spyderjon or other tech types? Apologies if we are retreading old ground
How many teeth per cm do I need to look for in a fine file for base filing i.e. filing down Ptex repairs etc without damaging rest of base? NOT for edge filing.
Thanks

fatbob, If you're just removing excess ptex (it's not really that hard, the ptex that is) carefully use a metal scraper.

Well, the person's real but it's just a made up name, see?

fatbob, what gsb said. The closer the angle of the base and scraper is to 90 degrees, the finer the shavings.

fatbob, what they said.
A 'mill/milled' file can be used at about 6 teeth per cm (14/15 tpi) but one slip & ya screwed. A 100mm flat surform blade could also be used.
For flattening down base repairs I prefer to use a combination of following, working from the middle of the repair outwards:
- a metal scraper
- a great little yellow plastic handled curved bladed surform (approx 60 x 30mm) for under £2 from B&Q
- a sharp 1" chisel
- medium/fine grade sandpaper
A number of stores sell £19 base rasps &/or £15 base planer's but neither beat the above which cost booger all in comparison.
If you do a lot of base repairs & you want to spend some dosh to obtain waaay better repair retention than is obtained from dripping in a candle then consider something like the lighter fuel powered Base Doc 'soldering iron' tool for properly welding in the repair material.

Anyway, snowHeads is much more fun if you do.

fatbob, If you know someone who uses a metal turning lathe they might be able get you a blade from a parting tool. It is made from HHS and extreemly hard and strong. The one I use is about 150mm long and 30mm deep, it also acts as a straight edge for checking the base.
Unlike the Toko metal scraper which bends and can cause the base to become concave, the parting tool is less likley to flex. I sharpen mine when needed on an oilstone and check that it is still true after.
