Small Draw Knife

I found an old jointer knife laying around the shop and had an AH HA moment. "That would
make a good draw knife blade"

It worked so great I made a champer guide for it.

Making a continuous closed loop sanding belt.

     

Old style sanding block on top  uses an open piece of paper.When front of paper wears you have to discard whole strip.
New design on bottom uses a continuous loop belt. When front wears the belt tension can be backed off enabling the belt to be rotated to a fresh spot.
The challenge was to be able to easily make the new continuous loop sanding belt for the new design block.  I'll provide a brief overview on making a continuous belt. For more details go HERE

 

 

 

Supplies needed to make a continuous belt.

Small section of cloth backed shop roll. 3M micro finishing film. The micro finishing paper is mi-liar backed.
A good brand of super glue.

 

 

 

 

A small section of the 3m micro finishing film is super glued to the cloth backed shop roll

Add glue to the other end.

Squeeze the joint.

I have found this splice using the mi-liar paper on a cloth backed shop roll makes an extremely tough and strong joint. I use the same process for belts that are power driven.

Because the mi-liar accepts super glue so well I have had great success with different belt materials other than a cloth back paper. 

 

 

 

Quick and dirty Spring Winder

Making small springs for miniature Colt

 The winder was fabricated using some scrap 80/20 parts in the scrap bin and a 5C spin fixture.Using a tail stock type support for the extra small mandrels will enable me to turn those extra small compression springs for the miniature Colt 1911.
The split Boxwood and brass thumb screw provides a safe and clean way to adjust tension on the piano wire as it is being rolled around the mandrel

 

 Above picture shows a rectangle mandrel installed for forming the rectangle magazine spring.

The spring above was "Stressed Relieved" before removing spring from the Mandrel.
This prevents the spring from being distorted when removed.To see what a non stress releived rectangle spring looks like and more pictures of the spring winder go.HERE 
The spring winder photos are at the end.

New design sanding block that has the ability to tighten the sand paper after installing .The design will support almost any thickness of paper.

Miniature Colt 1911 and New Style Mold frames

This is the first casting of the receive and slide,scale is .375

Above picture is all the 1911 parts that were 3D Printed. RTV molds were  made from these.

A few Pantograph projects

I offered to machine a friends 4 inch vise kit if he bought me one. He came out OK as the casting Kits were a little more involved than I had planned.
The overall length of the Wilton bullet vise kits is 4 inches. I decided to make a 1/2 scale of the kit with a few modifications. My castings will have the original Wilton logo and will have the female key way cast into the body eliminating a tedious broaching operation for the movable jaw.

Cerro metal molds

I reached a point in my 1/3 scale wheel lock project where I had all the master parts made and was ready to cast multible parts. In all my past miniature projects I have made various type molds for injecting the wax to be used for investment casting. For the wheel lock I decided to use plastic parts instead of wax because of the greater detail and sharp corners that can be achieved with plastic. In order to inject plastic into a mold I needed a mold material that could hold up to the higher temperatures and pressures used with a plastic injection machine. Following are a few photos of the mold making process and the cheap press I made from scrap parts, It is used to compress the Cerro metal quickly after the molded Cerro is poured in the mold. This compacts the Cerro metal causing a tighter crystal structure in the metal which produces extremely fine detail.Another benefit of the cerro molds is the expansion of the eutectic metal thus parts that are not smaller due to mold shrinkage, the cerro also cools the injected wax or plastic very quick which reduces cycle time of making parts.
