Stool Kit from Acer-Ferrous Toolworks

Paul Peters, of Acer-Ferrous, has developed a wooden screw and nut system that is designed for use as a shop stool.  The large 2″ thick by 8 1/2″ square nut is sized with room for four splayed legs to be attached through tapered holes. (Very much like a Windsor chair seat,or staked furniture.)  The threaded stem is 2 1/2″ diameter and threaded at two threads per inch.  The top end has a 2 1/2″ long by 1 1/2″ diameter tenon for mounting a seat on by boring a hole through and wedging from the top.  The stem is 15″ long overall with 12″ of threaded length, allowing for about 9″ of height adjustment.  Also included is a jam nut, which is spun against the base nut once the desired seat height is set.  It will keep the seat from turning while in use and also removes any play in the screw and nut.  All components are made of maple.

Price for the kit is $110.  They are available now in the store.

Improvements to the Acer-Ferrous Leg Vice Screws

Paul Peters, of Acer-Ferrous Toolworks, has made some changes to his leg vice screws.  They now have two garter slots; one for external garters, which is at the base of the hub, and one set back 1″ from the hub for those who wish to use an internal garter.  Both slots are 1/4″ wide and 2″ diameter, which will fit the brass garters we carry.   We still have several original black anodized aluminum garters that are 3/8″ thick which we are offering in conjunction with a matching screw. (These screws have a single garter groove for external use only.) The package is discounted and is priced at $175 for both the screw and garter together.  It is available here.

He is also offering this screw with a tiger maple head for those who want to add an extra flair to their bench.  These screws are priced at $175. This option may be purchased here.  See photo below.

New product: “Milkman’s Bench” screws

In the June 2013 issue of Popular Woodworking, Chris Schwarz wrote an article about a portable workbench dubbed the “Milkman’s bench.”  It is designed to clamp to any solid surface and provides a full range of clamping options for most tasks in a compact package.  I built several following the plans with no changes other than adding jaw liner to the tail vice for plane making and found them to be perfectly suited for holding the plane billets in any position needed.  Its compact size makes it easy to store and transport to demonstrations too. Chris wrote about his experience using this bench here.

It is a relatively easy project to make except for the wooden screws.  However, that just got a lot easier with the introduction of our new Acer-Ferrous wood screw set designed specifically for use on the Milkman’s bench.  The set includes two screws used in the twin screw area along the side of the bench and a single screw with a garter slot for use in the wagon vice.  These screws are made of hard maple and the threaded portion is 1 1/4″ diameter with 5 threads per inch.  The handles are octagonal in shape and provide plenty of grip for tightening. Width across the flats on the handles is 1 1/2″

The set of three screws is available for $85.  They can be purchased here.

Builders will still need to thread the holes for the screws but that is easily accomplished  using a 1 1/4″-5 tap available from the Beall Tool Company.

Acer-Ferrous Moxon Vice Kit

 

Acer-Ferrous Toolworks has introduced a screw kit for making a Moxon style bench top vice.  The kit includes two hand screws and matching nuts made of hard maple.  The screws are 1  1/2″  in diameter with 4 threads per inch.  Overall length is approximately 12″, with 8″ of threaded length and 4″ long handles.  The handles are octagonal, and measure 2″ across the flats, which gives plenty of torque for excellent gripping power.  The nuts are 1 1/8″ thick and 4″ square.

The customer supplies the material for the jaws.  By using 4″ wide stock, the back jaw will be the same height as the nuts, which will enhance the stability of the vice on the bench top. The vice may be clamped to the work bench using bar clamps or holdfasts. The jaws can be custom made to any length needed.  We suggest using material at least 1 1/2″ thick to minimize flexing under load.  The nuts are simply glued to the back jaw when the vice is assembled, being careful not to get any glue squeeze on the threaded portions.  Instructions are included.  No finish has been applied.  Price is $75 for the pair. These may be purchased here.

Acer Ferrous Toolworks Garters

Paul Peters, of Acer Ferrous Toolworks, has developed additional components for the leg vice wood screw.   The garter, which is used to attach the wood screw to the chop (movable jaw) of the vice, is now available.  This allows the chop to move in conjunction with the hub of the screw when opening the vice.  There is no need to pull the chop open by hand.  The garters are 4″ square, and are split in half to allow for installation around the screw.  He is transitioning from a thickness of 3/8″ to 1/4″ for these garters, which will slip into the grove at the base of the screw hub.  Four countersunk screw holes, and supplied screws, are all that is needed for installation.  The garter can be oriented either  square or in a diamond position, as shown.

Garters is available in either solid brass, which can be purchased here, or in aluminum.  At this time, the remaining Aluminum garters that are 3/8″ thick are being sold as part of a discounted package which includes the screw with a matching groove. Both come with matching screws.

Acer-Ferrous Toolworks leg vice screws

Acer-Ferrous Toolworks was started by a young man, Paul Peters, whom I have been mentoring in woodworking since he was a boy.  Paul recently graduated from a trade school as a machinist, and decided to combine his two interests, woodworking and metalworking, into a business venture.  He purchased a 1910 Monarch lathe, and made his own tooling to produce wood vice screws.  His first product, a leg vice screw and nut, is shown below.

The 2 1/2″ diameter, 2 threads per inch screw is made of hard maple ( Acer saccharum), riven out of the log to ensure straight grain, and vacuum kiln dried.  The octagonal hub is a separate piece of wood, and is threaded and glued to the screw.  Overall length of the screw is approximately 24″, of which 4″ is the hub.  The hub measures 3 1/2″ across the flats.  There are two 1/4″ moats cut into the screw; one at the base of the hub and the other 1″ below it. These grooves are at 2″ diameter and are for for the garter, either user supplied or available in brass or black anodized aluminum..  A 1″ diameter hole is also bored through the hub for the handle, also provided by the user.

The nut is also hard maple, and measures 8″ x 4″ x 2″, with the threaded hole centered in the face. This leaves plenty of room for mounting holes to be drilled.

As an accessory, garters are also available in either brass or black anodized aluminum.  More information about the garters can be found here.

The two piece design allows the option for making the hub of a different wood, and retaining the maple screw.  In fact, we are also offering this screw with a tiger maple hub for those wanting some extra flair. (See image below.)  Anyone interested in a custom hub, or with requests for other sizes, can contact Paul at prpinthehills@gmail.com

Red Rose Reproductions is currently marketing and selling these screws. Price is $155 for the standard screw and &175 for the tiger maple hub. To purchase Acer-Ferrous products, click here.
