Claw Hammer Test Print

Today I ran a test print of my claw hammer I designed over the last few days on the UP printer.  I wanted to check for size and scale and I may also take a cast from this into bronze.  I am very happy with the feel, form and size.  I am also going to 3D print one in hardened resin to test it’s durability.  I haven’t quite decided on how I will produce the handle yet.  I will be having a think about this over the next few weeks.  

    
   

 

Tension Saw Design

Over the last week I have been designing a tension saw I can 3D print and use both to make my jewellery as well as items for the house I am building.  Firstly I created a wire frame which looked very similar to my jewellery in triangulated forms.  When I piped this using T-splines it made the piece look almost sewn together, which I ran with.  It is still a triangulated form so I hope this means it will hold a lot of strength when in use.  I also made this from a frame to cut down on material for cost as well as weight in use.

Initially I designed a traditional fitting where the saw blade would have been bolted, however I changed this as I wanted a more contemporary design.

My final design I made bolts and a handle that match the saw frame.  I plan to 3D print the entire thing in the next few weeks using steel for the frame and bolts and either wood or plastic for the handle.

Claw Hammer

For the last day or two I have been designing a claw hammer for larger scale use such as building my house.  I went through a few designs and decided I would make use of the CAD and design the hammer so that I wouldn’t have to wedge the handle at the top in a traditional way.  I designed the handle and the hammer head so that they join in the handle shaft.  hammer9

I got a little carried away with the handle when the hammer head started to look a little like a seahorse.  I’m not sure if I will keep the base section exactly like this or if I will simplify it a little before production and comfort.  I am hoping to cast the top section in bronze and get the handle either milled in wood or 3D printed in hard clear resin.

Ceramic Ware- Update

Today I got back my shot glasses from their first glaze firing.  I have painted them all  with the green glaze I bought and tested a few months ago.  I decided to paint them all different  to each other so that when they are being used people know which one is their glass.

I am still not having a lot of luck with the wine goblets.  The one that I tested last I left to dry before cleaning up to see if it holds together better.  When I came to clean it up I noticed it had a slight lean and a small crack at the bottom of the stem.  It is still in tact and I have put it in to bisque fire however I am not very hopeful and I plan to redesign the whole goblet and start again to make it stronger.

 

On the plus side I got back two more pint glasses which I glazed today.  I am very please with how these are working out and I will soon have a set.

 

3D Printed Needle

A few weeks ago I designed a needle in CAD to try out in laser sintered steel.. I got the print back from Shapeways last week.  I am very pleased with the final result, However, I did have to file and sand it as the grains were quite prominent on the raw print and would have caught on fabric.  The needle also has a really nice weight to it.  I am a little concerned that it might be a little thick for some fabric.  I will try it out and if so I will file it down a little more.

 

3D Printed Hammer

For the last few days I have been working on finishing my hammer.  Initially I made a handle from an unknown wood I found in the park.  After Finishing the wood beautifully to a high polish I went to wedge the hammer head into the top and the wood split.

I then started again using a piece of oak.  I initially used my 3D printed chisel to carve the plank.  Although this was still cutting really well, I had to sharpen it regularly  to keep a good cutting edge.

After 3 hours of solid carving I hadn’t made that much of a dint in the wood.  I went over to the wood workshop to see if I could use the lathe  on it.  Malcom the technician offered an even better solution.  He showed me how to use a spindle shaver.  This is a tool I had never heard of before.  It is similar to a plane however you hold it with two hands and it has a handle on each side.With in about an hour I had carved a nice dainty shaped handle that was better proportioned to the hammer head.


I used my 3D printed chisel again to clean and scrape the wood before I sanded it.Finally I cut a wedge of walnut wood and a wedge out of the top of the handle.  I then added a little artificial chemical bonding (wood glue) and wedged the hammer head onto the handle.  I plan to polish the handle with Danish oil every day for a week or two.

I am very please with the result.  I plan to tweak it a little over the next week, however I can wait to start using it to see how it holds up.

Happy Ceramic Day…. So Far!

The plan that I came up with yesterday to leave the goblet alone to dry is so far working.  It was still standing after four hours so I am keeping my fingers crossed that this approach will work. 

 I also managed to cast another pint tumbler today.  I am starting to become really quick at these.  They cast like a dream, are easy to take out of the mold and are also very quick to clean up as they only have two seams.  The following image also shows the goblet I made on Monday which is also cracked at the stem. 

 This afternoon I got all my shot glasses from the bisque firing as well as one of the pint glasses.  I glazed these with clear porcelain glaze.  I plan to fire for a third time with the green glass I used for my test pieces.  I dipped all the vessels into the glaze and then touched up where my finger prints were with a paint brush.  Afterwards I removed the glaze from the underneath by rubbing them on a wet carpet.

Zig-zag Crochet

Yesterday I decided to learn a new pattern for crochet.  I have finished the bed blanket and sofa throw.  After living in Scotland for many years I have got used to often sitting with a blanket around my shoulders to keep warm.  So I decided my next project before moving back to the cushion covers will be a personal blanket.  This is why I wanted to test out another pattern as it wont need to match the rest of the furnishings. 

 I spent a few hours working on this yesterday but I have had difficulty at the corners and seem to be adding and taking away stitches at the edges.  I am really happy with the pattern however I need to take it apart and try to make the edges more perfect. 

 I have also managed to give myself an amazing crochet callus on my finger.  this is because my hook is a little rough on the edge my finger rests on.  I think I will try and print a hook on a better quality printer.

Whisky Glasses

This week I embarked on a run of making all my shot glasses.  The reason it took me so long to get to this point is that I have been testing lots of different sizes and glazes.  The mold for this differs from the one I used from the samples as I printed on half on its side which added a different and more defined texture to the of the piece. 

 The only tools I used to make these were the press mold and a sponge to clean off the edges.  I have now taken them to get fired and will glaze later next week. 

 

Handles

Yesterday I cast another cupboard door handle.  I have six to cast in total.  They are all similar to each other however some are twisted more than others.  When I poured the cast I thought it hadn’t worked properly.  It wasn’t until I opened up the mold that I was happily surprised.  I spent the afternoon cleaning up the piece with my files.  I have four more to cast and then I will solder on threads to the back of then so as they can be used for the cupboard doors.
