DIY Magnetic Bobbin Holder -> Singer 132K / 133K

[Constabulary]

Some may know the useful magnetic bobbin holders sold by GRABOBBIN and the like, you find them everywhere for approx 10€ / $12. They usually hold approx 20 G or A style bobbins (~20-22mm diameter) but I wanted one for my Singer 132K6 bobbins (34mm diameter) and none are available so I made one.

My bobbin holder is ~300mm long and can hold 19-20x Singer 132K style bobbins.

What you need is:

• a piece of 2" x 1" wood from the scrap box
• cheap magnetic knife holder:  https://www.ebay.de/itm/312739525221
• 32mm round router bit:  https://www.ebay.com/itm/401789386660
• 6mm router bit (already had one)

You can make 6 fairly long bobbin holder from the 3 knife holders. If you need fewer just look them up but the set of 3 were the cheapest I found broke down to 1 magnetic holder / 2 magnetic strips. I will make some more bobbin holders for other machines so I bought the set of 3.

Decal is a left over from a restoration project so its a nice add on here I think.

Some pictures - last picture shows a Grabbobin holder in comparison.

few more

BTW - I killed the cheap round router bit, the 6mm shaft was a bit to thin and bent but still worth it I think. Birch wood was too hard I guess. Should have dome this step by step and not in one run However - 8mm shaft was not available and 12mm shaft was too thick for my router.

Yes, deep and wide cuts should be done in increments.  Cleaner, neater job, and much safer.  Would not want to be around a bent router bit going 10000 rpm!

I like your bobbin holder, very neat, may do a couple for myself after I get some other jobs out of the way!

It bent not too much but when I tried a 2nd run for another bobbin holder I noticed the grove became wider and wider (just 1mm overall but still...) so the bit went to the trash immediately!

I just made a few more bobbin holders from an old oak plank - one for the 45D91 and one for the 108w20 (with a different bit of course and step by step). I´ll make a few more tomorrow...

Ouh - in the 2nd post I wrote birch wood - but I meant beech wood

Great idea Folker. I'll have to make one of those. Won't be as pretty as yours but will do the job. I think magnets have lots of uses in sewing. I have one beneath the top laminate on my Durkopp table and it's invaluable to catch those itty bitty screws that normally fall on the floor. Do all tables have one of these?

Looks good, you are a clever boy.

Only one possible problem - make sure you don't buy aluminium bobbins.

[jimi]

Looks great Folker, you could sell them on ebay??

Ejem...ejem.. the bobbins for my 335 are all aluminium.

The holders look really nice. I do have one caution when using any items with any magnet like those used in magnetic edge guides or holders. The amount metal items will be affected is going to depend upon the type and size of the magnetic, the metal of the item and how the item becomes magnetized either through passive transference (direct contact) and intentional (rubbing the item against the magnetic). Since metal items can become magnetized like bobbins which could potentially affect how the bobbin spins or is attracted to the bobbin case. The larger magnetic edge guides can lift the bobbin up in the bobbin holder which can prevent bobbin spin particularly in patcher type machines.

Thats no problem, the magnets here are rather weak and not as strong as neodymium magnets or magnetic edge guides. I´m using the orig. Grabobbin holder (with Bernina logo) for years and the bobbins are not much magnetized and it is not not causing any issues. I think when you have an anti backslash spring in your bobbin case it is causing more "rubbing".

If you do not have a router + bits and you need them for standard G style bobbins you can buy them quite cheap on Ebay

I just wanted to make one for my larger size 132K bobbins but figured I have a few other bits that fit for my other bobbins so I went on and made some more... little funny weekend project.

Jimi as you know the earth curvature is different in Spain and I´m sure you can use aluminum magnets. You only have to put them in a solution of type A moon water and type Z unicorn dust first - problem solved!

I have the moon water but need the dust  If you varnish the half round that you routed it would look 100% real deal and bought from the shop
