Hey all, quick prep question. I’m looking at buying this dremel set with these accessories.  I want it for smoothing (removing pen marks) polishing and sharpening the tip of my TT.

Would i need to buy anything else to do this or is everything in this set? This is for hard Yorkshire Coast material
Thanks

Nice! 

I need to get a dremel for Tidgy's beak.:)

I imagine that should do what you require, but wait for people who've actually used one........

I think i need a diamond cutting wheel for the sharpening, but what about polishing and grinding?

I have one and it doesn't get a lot of use. I find matrix-shaping can be done using the scribe initially by moving it back and forth (transversely left to right) and levelling the peaks down, and then give it a healthy blast of abrasion to smooth out any residual rough spots. As for sharpening the scribe tip, that depends on the metal... I don't think the sand grit on the Dremel heads would make it easy to sharpen a carbide tip (or it might take an eternity). It may be more likely that you'll burn through the head before you get a nice new edge on the scribe tip!

 

The one thing you can do with this unit, if you're so inclined, is use the brass brush attachment and apply it to a sturdy fossil to give it a brassy/gold finish. Not something I personally favour in a fossil, but some people like the look.

 

The set looks like it has the basics, but the heads are somewhat universal so you could probably go to a discount shop and pick up replacement packs that will fit most units. The collar can be adjusted to tighten around most of the similar sized heads. Just make sure you do tighten it well before use (and sometimes after a period of use) as the collar can lose its grip from the vibration, and make the head wobble. Mine came with additional types of specialized heads than your unit but, again, heads are easy and cheap to find. Most of them you'll probably never end up using. :P 

 

And, of course, an obligatory mention of caution in using any Dremel tool for an extended period of time: as the vibration does impart itself to both the fossil and the hand, extended or prolonged usage is not advised as it can result in nerve damage known as "white finger." No more than ten minutes at a time is best, performed in warmer temperature conditions (do not operate in cooler temps as that can reduce necessary blood flow). If your hand starts to tingle, stop immediately and take a break.

Welp, if you're going to use a dremel for prep work then I suggest a flex shaft as holding the bulky tool gets annoying and over tine will cause your hand to cramp. Below is an image of the flex shaft. Its about $34 USD, so id say no more than 27-29 quid for you.

These rotary tools are very versatile with a wide variety of cutting and burnishing heads.  The kit you pictured provides a bare-bones assortment.  Fortunately, these heads are widely available.  You can even buy a set of colletts to accommodate special heads such as dental tools.  I own two:  one is a heavy duty hanger with a flex-shaft handpiece; the other is battery-operated and is mostly used for minor clean-up or to burnish fossils.

I love my Dremels. For harder material you really must go with diamond accessories.  At this size such is very easy to afford and should be purchased in sets.

As for chiseling my friend Eddie Rucks in Ft. Drum, Florida,  is a fan of the flattened wood nail in the business end of his dremel claiming that it is superior to

more expensive specialist prep tools(vid).  I have used this method successfully but do not have air scribes or chisels to compare it against.

Best of luck.

 

PS.. flex shaft is worth every penny.

For me. i bought one of the Foredom's.  those have the flexible shaft that Raggedy Man mentioned.   It really and truly will make your job easy.  I went through two dremels before I bought the foredom.  and you can get all kinds of bits for whatever you need to work on.  You can also get different hand pieces too.    Its a bit exspensive, but in the long run you will be glad you did.  Good luck.

Does it come with a chuck or do you have to buy that separately?

Hi there,

 

I use dremel for finishing purpose also (removing pen marks)

With the shale where i find my trilos, it works like a charm, though the flexible is a must.

I mostly use the "abrasive rolls" ( like the one pictured abouve), different size.

I tried diamond disk for cutting purpose some time ago but the  disks just dont last so i ll keep going now and then to the place i can get access to big saws.

Liam, for me the Dremel with the flexi shaft is essential. Do get the flexi shaft as you have much more control. I use mine for smoothing out matrix and sharpening my pen tips.

I would also strongly suggest the flex shaft. The attachments that you have shown will be of little use in fossil prepping. Diamond bits, especially round ones are the way to go for smoothing matrix. These can be found on the internet or the auction site.

No chuck. Just pop in in the hole and turn the fitting collar down tight.

Just to update my beginners findings too - a 50mm on my "rotary tool" is far better than the 120mm concrete cutter on my grinder!!

Just had a go at prepping this pseudo i found a month or two ago on the Yorkshire Coast.

 

first time using the dremel to smooth, any tips welcome. The center was hard to prep so i didnt want to ruin it and left it.
