Thread: Hollows and rounds

Ian,

I've attached a photo showing two different cove ovolo profiles. The one on the right has arcs of 60º and the one on the left has arcs of 90º. You can see the layout on the ends of the stock. Hollows and rounds have 60º arcs on their soles. Once the profile is defined with rabbets and chamfers are cut to prevent wear to the profile of the hollow plane it's easy to use a partially completed profile to guide the plane to cut any amount of arc equal to or greater than the actual profile of the plane. That's why these planes aren't fenced.

Hmm - I see your point, now, Larry. I think the hollows I have have been mucked about, as the smaller one has an arc much more than 90 - it's probably closer to 120, and the larger is also >90. So no wonder I have problems trying to get them to work properly. I freely admit to spending very little time & thought on them as I have few situations where they would come into their own, unlike the rounds. I'll make a proper effort to sort them out, someday soon, but it looks like I will have to repair the soles & reprofile the cutters....

Cheers,

I narrowed down the numbering using this chart

The sizes seemed to correspond almost exactly to my set of 10s and 14s (all the planes are British made).

Hi All
slightly off the topic but does anyone happen to know of a similar chart etc relating to the size and numbering of 'travishers' ie concave cutting spokeshaves.

Ive got one of the low angle No# 5, but am looking to make my own improved high angle version for use when concaving cricket bats and I just thought it would be benefitial to get my head around what the sizes mean. I purchased it from the UK a couple of years ago,and asked at the time what the sizes related to but they couldnt shed any light on it, And its not a inch value of the radius as it gets tighter the higher the number?
Its got me stumped - so if theres any cluey readers out there, any help would be most appreiciated

I bought a pair of Terry Gordon's 3/4" H and R planes and am enjoying making my first hand made rule joint. Not very good at it yet ... but getting there.
As usual his planes are beautifully made and his sharpening tips are hanging on the wall waiting for the dreaded day I'll need them.
