I recently bought a few Henry Taylor chisels and would like to pick up a few more. The only ones I've found have been at thebesthings.com. My problem is that TBT chisels are imperial and the chisels I have are metric. How can I determine what sizes I need to purchase? I want a #5 20mm 16mm 12mm and 8mm. Does anyone else sell HT. Woodcraft is no longer carrying them except what is left is clearance.
Thank

for calculation 25mm=1inch so

8mm is about 1/3 inch, 12mm is about 1/2 inch, 16mm is about 2/3 inch, 20mm is about 4/5 inch... the approxiamation is good enough to choose the chisels...
cant help with question who sells these

What a fantastic day it will be when the US leaps into the 21st C and catches up with the rest of civilisation and the metric system. Till then follow Doris's conversions and remember that 1/8'' = 3mm is a useful approximation.

I usually google Metric to English conversion...there are plenty of sites out there that make the conversion.

It does require a bit of math, though, because most of the results are decimal rather than fractions...For most of my work (we work with some authors who send us everything in metric) I usually round it to the nearest 1/4" (.25")

The woodcarver's supply catalog has Henry Taylor tools and in the catalog they show the "footprint" of the tip right on the page beside the list of tools.
I always went by the "picture of the tool's tip footprint" when ordering...... Yep, that one looks like the size I want......

1" = 24.5mm.......so call it 24, and that make the conversions pretty easy.

1/4" = 24mm divided by 4 or 6mm. So 3/4"= 6mm
times 3.

1/2" = 24mm divided by 2 or 12mm.

Same for 1/8ths, and even 16th.

Or check out Lynn's humorous take on the conversions:

It's good to know that it's acceptable to pick and choose between the two systems of measurement I recently assembled a mobile base for my bandsaw. According to the instructions you could use either a 9/16 or 14mm wrench to tighten the bolts. After rounding over several nuts and bolts I realized that close in some things is not good enough!
Loved Lynn's "conversion" chart.
I'll check out LV and others for some additional tools.
Thanks again

You are absoloutely right about that "dual use" of wrenches. Even a proper wrench, worn by only a few thousandths will round over a bolt head or nut. On the other hand (are different fingers) a couple thousandths of an inch or mm won't make a whit of difference inthe width of a gouge or chisle.

All I know for sure is that us "old timers" are bound to look at everything in feet and inches and have to mentally convert these into metric when the occasion arises. The kids today are pretty well schooled in the metric system and it is natural for them.
