Thread: D2 Plane Blades - Batch Order 02

Due to interest I have opened the plane batch 02. See below for attached file with members names, their allocations and cost.

Attachment 61907

I have listed a smaller size blade useful for block planes, instrument makers planes, chair devils/scrapers, and spokeshaves, low angle spokeshaves, etc.. Something in the size of 40 mm x 4 mm x What ever length people like.

These are the sizes currently available and their prices, I still need to confirm, the prices for the 40 x 4 mm blades:

Attachment 61873

*NOTE* We must buy all ground D2 flats in 1030 mm lengths If we do not get orders for a full 1030 length in a specific size then we cannot order that size ground D2 flat and some people may miss out on blades they wanted.

1030 mm of 40 mm x 4 mm ----- 300 mm claimed with 700 left for other members to claim

1030 mm of 50 mm x 8 mm ----- 1030 mm claimed with NIL left for other members to claim SOLD OUT

3060 mm of 60 mm x 8 mm ----- 3060 mm claimed with NIL left for other members to claim SOLD OUT

2060 mm of 80 mm x 8 mm ----- 1250 mm claimed with 750 left for other members to claim

If you are interested in 50 mm x 8 mm and the 60 mm x 8 mm PM me.

Sorry to throw a spanner in the works but if you check my earlier post i only asked for one of each in 100mm long

Cheers

Matt

Thanks for checking Matt, I will get people to confirm all orders before proceeding.

My order is correct

Think I might take a foray into this plane making business, so with that, put me down for 100mm each of the 50x8 and 60x8

I have started a related thread on HNT Gordon planes and the D2 blades here.

*NOTE*

If you intend to use your batch 02 blades with some form of mechanical adjuster, it would be best that we drill the blades in their annealed (soft) state. If you intend to use a mechanical adjuster please post to discus your needs, and to make suitable arrangements.

Depending on cost, I reckon that it is worth getting all my blades drilled - there's nothing to stop you putting a blade with a hole in it in a wedged plane, but you can't make an adjustable plane without a hole!

Non of my planes will have adjusters in this batch 02. So their would be no need to drill mine or anyone else who will not be using an adjuster.

If you are in need of an adjuster the other problem is what kind of an adjuster will you be using with what kind of blade as their are 8 blade types in batch 02.

Each style of adjuster would require a different hole placement and size. All this poses a challenge that could not be resolved by simple randomly drilling holes into a blade.

Here are some samples of just a few possible hole placements, and we could not accommodate all of the possible variations.







Short of manufacturing adjusters ourselves it seems that on second thought that members will need at this time to make arrangements to drill adjuster holes themselves if they intend to use an mechanical adjuster.

Can anyone recommend the type of drill or cutter that will drill D2 at Rc 60 - 62?

I have thoughts about making an adjuster, as I know two machinist metal lathe turners who could make a mechanical adjuster or even teach me how to make it myself. However that will have to be another thread.

It will be possible to drill a hole in these blades using a carbide tipped drill and lots of coolant. A sharpened masonry bit should be able to do it.

An alternative to a hole is a notch which can be cut with a narrow kerf cutting wheel. I have done this in a 3 mm shoulder plane blade made from an old file so adding a notch to an 8 mm blade should possible. Using a 100 mm diameter wheel a 2 mm deep notch will be about 40 mm long. If you wait for the wheel to be worn down to 75 mm diameter it will be 35 mm long.

Hi TS,

Could you please add 2 blades to my order, 2 by 100mm long by 40mm wide by 4mm thick. The list in Post #37 does not show these yet, (from previous PM sent).

Thanks and cheers
Pops

OK, having read TS and Bob's posts, I will drill any holls or cut any notches myself.

We have D2 left in the following sizes.

In the 40 x 4 mm I have 300 mm left
In the 50 x 8 mm I have 750 mm left
In the 60 x 8 mm I have 700 mm left
In the 80 x 8 mm I have 650 mm left

The tally stands at 54 blades allocated so far.

Based on discussion with members Batch 02 blades will all have a primary bevel ground at 25º.

Batch 02 will officially close on Monday the 14th of January 2008. I will continue taking order up to that date.

Attached is the updated list.

Yes. Reshaping of carbide tipped stone drill bits into drilling hardened steel has been in use. It usually requires very good drill tip shaping/sharpening device. I know some people have made gun drill type of drill bits at home using long masonry drills as templates.

In industrial solutions, more often there has been used high cobalt alloyed bits specially designed for making clean cuts through hardened components. It is still quite slow and careful work to get a clean hole in some reasonable time.

During 50's, there was developed a HSS having composition of 1.4C4Cr4V9W4Mo12Co (balance iron), possible to temper up to 70 Rc and still provide substantial toughness. The substitution of Mo for W helps forgeability, but is indeed very difficult to grind. It's microstructure contains large amount of fine special carbides in uniform dispersion in a refractory matrix kind of metal binder system. I have seen that stuff once. (Nowadays they manufacture hard and high toughness components via powder metal routes, HIPping or otherwise compacting and sintering. Much better quality of templates than by casting)

Grobet/Vallorbe has announced their Valtitan series of metal files. They are said to provide hardness levels up to 70-72 Rc. I have no personal experience on Valtitan series, so I can't say whether they could help with (bevel) shaping of hardened D2.
