Making Stuff Part 9

1991CC96-8B96-4C54-B8C8-185597AEBAA0_1_105_cFollowing on from the success of making the two teddy bears out of MDF as gifts for new born babies, I decided to progress the clock making using MDF rather than pine. Whilst the clock I did for my brother came out OK, it took a lot of effort to get a good finish. As mentioned in my previous blog he had shown the fish clock he’d painted to a few of his piscatorial mates and they all loved it so he suggested if I knocked out a few and he’d sell them. I therefore got about designing a few different versions so they had a choice. 71B98BFD-194B-4CA9-A775-FB6ED0B87702_1_105_cAs I was due to meet up with Alan the following weekend I had to crack on with batching them up, 7CA179DF-2D5D-49FE-9CA8-1A011DE980B7_1_105_cpainting and ordering more quartz clock parts as I didn’t have enough to cover the number of units I was making.

I’d purchased some green and grey paint as Alan had suggested these colours would be popular with fishermen and who’s to argue as they did come out rather well when sprayed up. I fitted the clock mechanism and wrapped them ready for transport. EB75365D-2FB7-45D0-B658-E8AAC9F5E152_1_105_cI did have a couple of failures, where the numbers on the face came out uneven (a human problem rather than CNC) so decided to paint them in brighter colours and one of them is now adorned on my neighbour Nick’s garage wall. Alan already had buyers for three of the clocks and he says he’s going to put the rest on eBay. I’m not sure if they’ll sell but hey I never intended to make stuff to sell so it might help me recoup some of my costs back.

Unfortunately due to the Coronavirus outbreak, our plans to meet up at the weekend were dashed so I still have the clocks but hopefully he’ll collect them soon.

7E61C3D3-3FBA-4958-A421-0DC186F6A797_1_105_cHe also mentioned my ability to make clocks to another friend and was asked whether I could make one for his mates wife as a birthday present. He sent me the logo so I got to work on the design. With the holiday we had planned having to be cancelled this week, I had plenty of time to knock out the designs and produce the two new versions of what is becoming my signature product. Again, I was rather pleased with the outcome. The same mate also asked me to make two clocks for his mum and partner’s mum so again, D49DD4EB-B29B-485D-A6B3-8D2437465E26_1_105_cI found a picture of a flower and added some simple text. They’ve now been painted and await the mechanism fitting and should be ready for collection before Mothers Day.

Another line I’ve been trying to produce is signs for homes and decided to try to create one out of plywood. I did try the same out of MDF but it didn’t work very well as part of the letters broke as I sanded the edges down.

F5C6B827-13F2-4790-BCBE-125ACDF57FC0_1_105_cUsing 18mm birch ply produced really crisp edges and was ideal for creating this type of sign. I decided to spray this in contrasting colours and even got a complement from Tina, who has been pretty indifferent to the things I’ve been making (I suppose there’s only so many ornaments a woman can have :))

2D9AEDA0-F257-491F-B415-1013A3D9FEE8_1_105_cIt’s now sitting in the windowsill in one of the bedrooms. This design came out really well and could be a best seller if I ever decided to knock out more of them.

First attempt, some of the detail didn't cut well

With the extra time this week I’ve also been finishing off Nick’s engagement plaque and presented it to him this week, along with the three earlier versions that didn’t come out as well as I had hoped.

I’ve still got loads of ideas to create more things and hopefully I’ll get some more done this week so watch this space for another update soon.

Making Stuff Part 8

9F55648E-C851-4F7E-9E6E-DC70671321E7_1_105_cHaving successfully created a clock out of a sheet of perspex, I thought I’d have a go at creating a sign that I could stick on my desk at work. I managed to find some recycled pieces of white melamine MDF and thought it would be an ideal canvas for making a sign.

Using the VCarve software, I created the view I wanted and sent the instructions to my Workbee. Pleasingly the results were excellent and the final sign looked very professional. I then knocked out further signs for my colleagues at work so they didn’t feel left out. When I handed them out, they loved them. I neglected to mention that the wood was recovered from my old shoe rack I salvaged 🙂

F0B676F5-8BAC-4713-9CBD-AB4EFEA3E10F_1_105_cAs well as the signs for work, I also designed a Virgin Media sign using another piece of Stephen’s worktop (those off-cuts  are definitely a gift that keeps on giving for sure!). It now has pride of place beneath my work screen and has received many positive comments.

5585D326-5A7F-4D42-8460-3384256DB82C_1_105_cNext, was a more ambitious project which really did show the power of a CNC machine. Using an off-cut of sapele hardwood and another slab of the oak worktop, I created a crib board that I will be giving to my dad for his birthday next week. The template for this was created by the people at Vectric but I had to adapt the settings in order for it to be produced on my machine. I firstly cut the lid and VCarved his name, but when I came to turning the piece over to cut the reverse I misaligned the timber and when the machine cut out the circle it was not perfect. As it was going to be a gift I started again and the next attempt was much better. I then started the main b57D2D319-F1C7-47D6-A1EA-8566F4A6C75D_1_105_coard. Preparing the slab of worktop took some time as I had to make sure it was absolutely flat to so that it carved correctly. Fortunately, the many machines I’d gathered over the past year made this task fairly easy and I soon had it sized and screwed down on the machine bed. I kicked off the instructions from my laptop and watched in amazement as the crib board slowly started to take shape. It is fascinating to watch the CNC follow the tool-path exactly as instructed and I was in awe when it started to drill the 245 holes, all in the correct place and spaced out exactly as it was shown in the software.IMG_1025

Having had some success with making wooden and acrylic clocks, it was inevitable that I would get a request to make a bespoke one. So when my brother visited a couple of weeks ago, he mentioned he wanted a clock for his ‘shoffice’ with a picture of a fish on it. A quick Google and I soon found an ideal jpg to use and was designing his new timepiece in next to no time at all. Thirty minutes later and he was holding his new pine clock.

d37c5be3-a0b4-4d4a-96d2-275c879b842f 2He was so impressed he suggested that the clocks would be very popular with his fishing mates and easy to sell online too. I wasn’t so sure until Alan sent me a picture a few days later of the clock that he’d painted and now has pride of place in his home office. He said he’d easily sell more of the same so I got to work making a few more, with different fish designs. I’ll share the results in a later post, once they are fully cut and painted.

I also had a request from our neighbour Nick, who informed me he’d just got engaged to his long time girlfriend and suggested I make him a sign to commemorate the union.

IMG_2296Again, I got to work on the design and soon cut a version of the sign out of MDF. Unfortunately the design was a bit intricate and some of the smaller bits broke as I tried to sand it down. Version 2 and I tried using a piece of sapele but this time the text didn’t carve correctly. Version 3 was better as I used a larger piece of MDF, but I was not pleased with the outcome. I tried painting it but that didn’t improve it either so I’m not going back to hardwood and attempting to make it in oak. Watch this space to see how I get on.

EC05B215-873D-4B62-B532-5F75A335651C_1_105_cLast week I got a text from Matt’s girlfriend Chloe saying that her mum’s boyfriend’s daughter had just had a baby boy and could I make him a sign to celebrate the birth. I soon found a teddy bear picture to use as a template and knocked up a plaque with his name, date of birth and birth weight. I have just had a text from Chloe saying they loved it. Phew.

So my exploration into CNC machining is turning out to be very fulfilling and even my family are pleased with the results so far.

Making Stuff Part 7

9FDE377F-98C5-45F3-9DB6-F0E131B0E1D0_1_105_cHaving started my CNC journey in such a positive manner, it nearly all went up in flames…literally!

7CDE102E-C670-4749-8DA2-0C9301547E6E_1_105_cI’d continued to machine some of the designs I’d created in VCarve, inspired by ideas I’d seen in Pinterest and other online sites. As an avid Watford fan I had taken an image of the club badge and imported into the design programme, converted it to vectors and worked out the tool-paths needed to create a 2.5D version of the badge. I then set the machine up to create the model using a scrap piece of MDF, securing the wood down using masking tape and super glue (an idea I’d seen on YouTube).

Considering this was one of the first jobs completed in MDF, I was pleased with the outcome and spurred me on to produce more things. 4706B9E2-D1D8-43A5-A90D-891EB5D14EFF_1_105_c

Another one of the Pinterest ideas I’d seen was a wooden clock with the numbers cut out so I thought I’d give it a go. I used VCarve to outline the design and found a bit of pine which was an ideal size for the job. Again, I set up the tool-paths and sent the instructions to the machine. CF906E97-E64E-4B19-B2B1-9110A049033C_1_105_cI will admit that watching the CNC follow the paths is mesmerising as it slowly reveals the piece you’ve created. I also added some VCarve text to the centre and amazingly I had a completed clock.

I’d purchased a cheap quartz clock from Ebay and soon had a working timepiece hanging from my garage wall.

 

0C39D8C5-4994-4B7D-84D3-341E42A31342_1_105_cBuoyed on from the successes I’d had so far, I decided to try making a newer version of the joined hearts, using a slightly thicker piece of oak. I had changed the design in VCarve to improve the shape and make the base more sturdy. Again, I secured the timber on the board using my tape and superglue trick and set the machine going.

And then disaster struck.

569E0BE3-C5D5-48F3-A435-1D47A3AE10F0_1_105_c As the router began it’s second tool-path run, it suddenly veered off in the wrong direction, slicing through part of the work piece. I stopped the machine and took the wood off the spoil board.

I then ran the file again, without the wood, trying to understand what had gone wrong. This time the machine went haywire, with the router plunging straight into the spoil board. I sent the machine back to home but forgot to switch off the router and it cut a channel the length of the board below and then proceeded to start drilling into the MDF beneath, causing a small amount of smoke. I cut the power to the router, hit the emergency button, which switches off the power to the duet board and killed all processes running.

I then went about testing the safety switches, which should have prevented this incident from occurring and found that one of the wires to the Z Axis arm had been severed by the wheels. This meant the CNC couldn’t detect when the router had reached the bottom of it’s reach and tried to drill through the spoil board and, if I’d not stopped it, my bench too!

I soon repaired the wire, enclosing it in piece of sheathing for added protection and retested the switch, making sure it stopped the arm when it was closed. CB5F309B-7312-4EC4-A46C-BEB2D14FDF73_1_105_cDisaster averted.

Next, was to try the machine out in cutting acrylic (perspex) having bought a sheet of A3 from Ebay for £6. Again, I wanted to have a go at making a clock as I’d seen a great design on Pinterest and thought I could reproduce it in plastic. The router bits I’d bought from Oooznest were idea for cutting acrylic and make quick work of the design I’d created in VCarve Desktop.

56ECDE98-A980-4625-A16D-DF1D87ED4276_1_105_cI used another of the quartz clocks I’d bought from Ebay and presented it to Tina, as she’d said she needed one in her sewing room. I was pleased with the look, although next time I may try to add an LED to back light the numbers, to help them stand out a bit.

So I was really now progressing my designs into reality and getting pleasing results so I decided to get a bit more ambitious and create a crib board for my dad’s birthday, taking the idea from the Vectric website.

More of this on my next update.
