Threading With Die - Thread Cutting

Tuesday, November 29, 2016

The setting dies I purchased did not fit to my handpress . These screw turned out to be British Standard Whitworth (BSW) thread. So I ordered a dice in BSW size to re-threading the setting dies. History of Joseph Whitworth behind the BSW is quite interesting, to me with no engineering background.

Using proper lubricant is necessary.

The 5/16W18 dice I bought. From now on, I don't have to worry about threadsize of setting dices for my handpress when I order.

The hardest part in this kind of project is holding threads with a bench vice. The vice did't grip the cylindrical shape. Eventually I had to sand off cylinder to make partially flat surface.

Now the setting dies fit and my handpress works all good.

If things don't work. You just have to make it work.

Stitching Punch With Drill Press Stand For Leathercraft

Saturday, November 5, 2016

This is a simple drill press stand mods to punch stitching holes in leather. I found a drill stand and a hand drill at a junkyard sales. I cut the head of the hand drill and put it to the stand. 

I see similar projects and studied them on the web. The common issue of this method seems to be that drill bit would be pushed back when pressing. To not that happen, I cut a piece of alminum plate to lock the drill bit for not been pushed back.

These plates are placed like this.

This hand press method is useful when you work at night without banging a hammer.

Vintage Embroidery Sewing Machine Minico - Pantograph Embroidery Machine

Friday, October 21, 2016

This is a toy sewing machine manufacture by Maruzen Sewing Machine in Japan (later, Jaguar machine). With this Sewing Machine, your own design or monogram can be easily copied as embroidery.

It use a pantrogrph to copie images. I find it exciting to see such a mechanism before the CNC era in a toy. The shuttle attached with a pantrogrph underneath moves in multi-direction.

I did quick demo. It works well but needs more precision. I find it hard to operate the moving shuttle instead of moving a stylus.

It has retro tacky 80s -ish design.

Using a laser cut template would work for producing a nice embroidery.

The machine is operated with two 1.5V batteries or AC.

Mini Drill Mods For Drill Press Stand

Sunday, June 26, 2016

I have a proxxon mini drill and a drill press stand for small projects. The drill has a trigger switch with mechanical lock to hold the trigger. The locking feature is hard to operate when the drill is attached to the stand. Also the lock sometimes doesn't work properly.

My solution for this problem is installing a toggle switch that bypass the trigger switch. I'm a big fan of a toggle switch as it can be easily installed. All you need to do is drilling a hole for the switch.

In this simple mod, my plan was leaving what's already there and adding a new feature.

When the toggle is ON, the motor runs. When the toggle is OFF, the trigger switch is used as a hand drill.

If you use a drill press with drill press stand, this mod would make the operation very easy.

Turn Gocco Printer into a UV Exposure unit

Tuesday, June 7, 2016

For my printmaking projects, I turned a Gocco printer into a mini UV Exposure unit.

Do you remember Gocco screen printer invented in Japan from the'70s? Gocco process screens with flash bulbs and print. Although the product is discontinued, some people still use Gocco to print their artwork.

I simply installed a 4W lamp unit to the lamp housing of Gocco.

The lamp house, itself can be used for other projects that need UV like curing UV-resin.

Built in On/Off Switch and 6V AC power jack.

The unit has a thick foam pad. On top of the form pad, there is thick clear acrylic plate that presses a film onto a photo-polymer plate or screen. I use two snap locks to keep the film and plate together tightly and make almost airtight during UV-exposed.

With this unit, I did successfully process some photo-polymer plates.

Mattel Vac-U-Form Upgrading

Tuesday, April 12, 2016

I installed the upgrade kit to Mattel Vac-U-Form. The solid punched metal platform and the metal lid are looking good. Although the kit is quite expensive (mostly the shipping), the contents are well thought out.

Good quality of products such as a silicone lubricant which is used for underwater photography. The instruction included is very easy to follow. Even a drill bit is provided.

Before the upgrading, I was thinking to disassemble a Vac-U-Form to work done. However there is no screws on the body. For instead, the outer steal is folded and punched by a few rivets. Unlike plastic toys these days, Vac-U-Form from the 60's got some quality.

First, I drilled a hole to install the new silicone valve. The initial valve was just a thin flapper rubber sheet.

The new valve is installed.

Cleaning the cylinder with paper towels. I stuffed paper towles in the cylinder then moved the piston up and down.

Now the cylinder clean and old grease is gone. Then new silicone lubricant is applied in the cylinder. Also, around the floor of the cylinder, the silicone sealant is applied which is provided too.

The Vac-U-Form can be more than a vintage toy from the 60's. If you are into crafting small projects with vacuum forming, it is definitely a good craft tool on your working table

Screen Printing Press

Wednesday, April 6, 2016

This is a screen printing press I built. Some piece of 62x37mm SPF lumber are used for the main construction and lumber core plywood for the platen and the base.

My router table previously built did good job for making lap joints.

The arm bracket is made with two of modified hobby cramps screwed to the aluminum angle.

Before I build this press, my concern of this project is how the arm swings. I see some presses on the web use springs to pull the arm. Since I am not sure what size of screen frame I am going to use or how heavy the screen will be, choosing the ideal springs for the arm might be little difficult.
So I figured and go primitive way, Pulley Systems for the counter-weight.

The counter-weight for the arm is just attached with the cable to pull the arm up and down. To hang the counter-weight(the bottle of water in the photo), I put the little pulley in, which is a part of sliding door wheels.

The counter-weight is adjustable with how much the water is filled.

The adjuster for off-contact is screwed in.

Before I made a platen out of thick MDF table top but it was too heavy for this press. So I used lumber core instead.

The platen can be adujusted with sliding and tightening the nut

I have already an exposure unit for the screens. So I want to try and make the screens.

Thanks to Screen Printing Press | HaHa Bird for ideas.

Dent Repair - BIJOU BOX Windsor And Newton

Sunday, February 14, 2016

This is a vintage Windsor and Newton No.2 BIJOU BOX, water color set. I got mine at an antique shop.

The photo above is after the repair.

Although the bijou box looks like it has not been used at all, there was a dent on the lid. I thought I should repair the dent. I show you how I did it.

  • Reshaping support:

    First, I made a mounting base for the lid with rubber molding from the undamaged ridge of the lid.
    Then I put it on the damaged ridge and flip the lid. The mold is made of dense rubber material.

  • Tapping:

    I sand off tips of wooden sticks and used them as tapping tools with a little hummer.
    I tapped the dent very gentry to push it out.

  • Heating and Cooling method:

    After tapping session, I used a heatgun to heat around the dent and spray liquid gas with a canned gas daster inverted.

    This is a modified heatgun with a funnel on the tip.

    The metal is frozen.

    When the liquid gas freeze the heated dent, the metal will shrink a bit.
    The dent will become less or least noticeable.

    The repair completed.

    Note: please research and check the risk of using a canned gas daster inverted.
