Drive Belt Dressing

This stuff use to be available when tools and mills were powered by flat leather belts, jack shafts, and flywheels.  It keeps the belt tracking properly [providing the wheels are coplanar] and prevents the belt from slipping.

drive belt dressing

Works great on Foot Powered Treadle Lathes, sewing machine belts and drive bands on Spinning Wheels.  Based on an old formula this stuff is very sticky, it sticks to silicone, teflon and high molecular plastic, etc. etc.

The perforated paper tube keeps it from sticking to your fingers and can be peeled back as the belt dressing is used up.

And it is for sale at The Full Chisel Store.

Walking Wheel Spindle Head Repair II

I started talking about this restoration here.   I made a drawing for making a new maple whorl [head or flange] on the spindle.spindle head4

This is the whorl temporarly fit to the metal spindle, I will later roughen the spindle slightly, etch with garlic and glue in place with Fish Glue.  spindle head7

Here is what the mother-of-all looked like when it arrived, I discussed replacing the obviously newer maiden with a proper one.  My client said that would be fine but insisted as much of the original should be maintained, music to my ears.

Here is the new replacement in birch to match the original.

In order to get the finish to match the original it took several steps, the first is a mixture of Moses T’s St. John’s Oil and yellow ocher dry powdered pigment.

The next step is a coat of shellac with some burnt umber dry powdered pigment.

Then a bit of black iron oxide dry powdered pigment with shellac to get near the final color.

spindle head11

Then some abrasion of the shiny finish and a coat of wood ashes makes it a good match to the original, there is no way to do this in one step to match the old finishes.

Here is the damaged pulley on the shaft together with the replacement part and the pattern that matches what is remaining on the original.

Having fit up the two pieces, I etched them with garlic and glued them in place with Fish Glue.  It was impossible to clamp so I held it in my hands for 10 minutes then set it aside to cure.  A little work with a chisel and I gave it a coat of shellac with burnt umber pigment.  I will add a bit of black later.

spindle head12

I still need to braid up a couple of corn shuck bearings and tie them onto the maidens.  This is an unusual method of attaching the bearings, most are secured through a hole and fixed with a wedge.

spindle head5

I was able to fit the pieces back together to determine just how they were tied on.  This job is nearly complete.

I want to take this time to apologize for the inconvenience of my web site being down.  That is what happens when a woodworker delves into a field with which he has little knowledge.  Again sorry for your inconvenience.

Getting down to Brass Tacks

This term comes from the upholstery trade; brass tacks are the finishing touch and final job of an upholstered chair, settee, sofa, lounge, etc. as well as leather covered trunks.  So ‘getting down to brass tacks’ is the last part of the job.

tack

Here is a link to the website selling decent traditional brass tacks.  This link shows about the brass tacks.

brass tacks

My artwork [above] from 1994 was used by the site, I contacted the owner, proved I did the art and he sent me these tacks.  While they are not completely accurate, the originals were cast one piece, these brass tacks are the best available on the market.  They do pass the magnet test, which is a way to determine if the shanks are iron or steel.

If you are making 19th century accurate reproductions such as leather covered trunks, an upholstered piece of furniture or a brass tack knife sheath [the clinch looks correct] these tacks fit the bill.  I highly recommend them.

Walking Wheel Spindle Head restoration

After discussing the work via email, the owner sent me the mother-of-all for a walking wheel [wool wheel, or spindle wheel] for restoration.  It is an unusual spindle in that the corn shuck bearings are tied to the maidens, rather than being fixed through a hole with wedges.  It was missing the whorl [head or flange], the small pulley was damaged and one of the maidens was a replacement.

spindle head1

Here is a drawing of what the whorl will look like.

spindle head4

The owner insisted that the pulley be repaired rather than replaced, a person after my own heart, so turned up a piece that can be cut up for the repairs to the pulley.

Should be a fun little restoration project especially that tiny repair to the pulley.
