How to prep a fossil crab [entry level scribe compared]

I often get asked what tools I started with or what would be a good introduction to fossil prepping. The Dremel 290 engraver is what I started with and used on my first 2 crabs before I got a Suntech air scribe which I then used for 2 years. The Suntech air scribe I showed in the video takes the same stylus as the CP9361 which means it can use tungsten ones made for fossil prepping sold by a variety of places.

I’m trying to imagine how you felt the first time you used an airscribe to prep a fossil and how excited you must have been to get your own. Wow. This video is not only full of first-rate information about fossil prep equipment for different levels of commitment/time, but also the clear explanation of the vital safety equipment is something that all should listen to. Nerve and eye damage may be permanent; thank goodness you can protect yourself. Just as you don’t offer the top of your head to heavy concretions and rockslides falling down cliffs as you hunt. So important.

[@christianboutell7112]

In April this year we have our fossiling holiday booked,we fossil between seatown & lyme regis on the Jurassic coast in Dorset,our main focus is to find iron pyrite ammonites and belemnites,it's an incredible feeling to find these knowing you're the first to see them in 160 million years,this is the best time of year because the sea has spent the winter revealing these truely stunning specimens from the cliffs and mud slides,can't wait.

[@MamlamboFossils]

Sounds like an amazing experience!

Must have felt weird going back to using a Dremel after all these years with air tools! Great video

[@MamlamboFossils]

It really was! Your tungsten stylus tips made a huge difference though 😀

[@fossilguy]

Very useful video. I made up my mind to prep, but I didn't know which equipment to use. I'll try it next time. Thank you.

[@largent45]

That was a cool demonstration of both and comparison. It really depends on what you are doing with it and how much detail. The price difference is considerable! Thanks Morne!

[@annetalbot9151]

Thank you for that comparison. I found it very helpful and can't wait to get my dremel so I can start prepping some of my fossils that I've collected. Looking forward to the next update on the turtle skull

[@MamlamboFossils]

I'd be very selective, start with broken and damaged fossils 😀

[@annetalbot9151]

@@MamlamboFossils thank you, I will. The one thing I've really picked up on whilst watching prep videos is to take your time. Slow and steady wins the race....or in this case reveals the ammonite 😂

[@TheAlastairBrown]

Thanks Morne! I did have a brief crack at this, possibly with the same dremel on my half crab concretion, this video is a perfect tutorial for someone in my position, although a little more detail on knowing the plastic mix(I think you mentioned this in a separate vid), and also the planning of where to focus attention at the beginning was my issue - for my crab I wasn't even sure it was a crab. I ended up chipping off the side with a hammer, and did indeed find the bone of a leg. I'd never used a dremel before, and you're right, it got super hot, and man it does a workout on your hand. I hadn't appreciated just how much this was like stone - it sounds silly, but I had assumed it was softer - siltstone or mudstone makes you think of greywacke - but it's definitely STONE. Cheers for all your help!!!

[@MamlamboFossils]

Yeah, it's very very hard rock! Sometimes you're lucky and find a soft one, but most are very hard.

[@jasonking9401]

This is very informative! I am currently working with a hammer and chisel, I think the dremmel is the next logical step... I reckon I will reward myself with one if I find a nice fossil. 😎 Thanks Morne!

[@jjoyce73]

I just picked up a Dremel 290 and ordered the tips from Zoic! They're delayed because of an international shipping snafu with the Royal Mail, but I can't wait to try them! One thing about the Dremel is that it's very loud, much more than I expected. Probably not as loud as an air scribe, but very loud if you're in an apartment like me.

[@MamlamboFossils]

Awesome!! Yeah, they can be loud but much quieter than the air scribes!

[@linuskorff4074]

This is a really good fossil to describe how to prep fossils like a crab. Even to I have a pneumatic pen and actually did prep quite a few fossils they were never a crab.

[@kirkgraham9968]

When I was little, my Mom took me to the Houston Museum of Natural Science. The dinosaur exhibit was VERY cool, but small at the time. It was a slow day, so one of the employees came over and took us to an Employees Only area. There was a team of 3 people chipping away at some brand new fossils. They showed me a small bird or raptor that they had been working on for a few months. They offered to let me touch it, but I was too scared lol. When the huge new exhibit was finally done a few years later, it was awesome to see those same fossils prepped and on display.

[@garydargan6]

I still use an old Burgess vibro-tool. It is probably heavier than the Dremel and I find that just resting it in the hand and guiding it while letting the weight of the machine do the work dies the trick. I also had a piece of brass rod machined the right size to fit in the chuck. A hole in the end lets me insert a small nail which I hold in with a grub screw to do finer detailed work. The nails are cheap and quick to replace when they wear out. You can also adjust the stroke of the Burgess tool for more delicate work. You can solve the lack of airflow on the Dremel by getting some small brass tubing from a train modelling shop and clamping it to the tool with rubber bands. You can connect the tube to a cheap aquarium air pump with some fine plastic air hose. Tried looking up Zoic tools but the website isn't working.

[@MamlamboFossils]

Try this link: www.zoicpalaeotech.co.uk/ Sounds like you had engineered quite a good fossil prep kit there!

[@Patriot-rising]

Love the suggestion of the Dremel. I already have other means to prep fossils. I do however like the idea of good vibrations and the glove of love. 😂

@@MamlamboFossils Also, when you applied the Paraloid, did you get it pre-mixed or did you dissolve it yourself?

[@randalljones4370]

As a dentist, I can vouch for the benefit of well-designed tools. For me, it'd be like trying to do a crown prep with a rotary Dremel. BTW, I use a Dremel a lot when I'm making my lap steel guitars, but I tend to burn up the bushings because I grip the casing so hard over the bushing covers. It only takes a few minutes with the wrong grip and bushings heat up... I had to quit using my hay-bale-lifting/tooth-pulling hand strength when holding that thing... it got expensive, lol. I did eventually buy a Foredam tool, but I haven't built any new instruments in a while...plus it's a rotary so it's a non-starter (and that flex-shaft may get heavy after a few hours) for fossil work. I need to get out to our coastline and see what has fallen out of the cliffs.. . we've had a week of freezing nights, which usually loosens the rocks a bit.

[@MamlamboFossils]

Thanks for a great comment! I know what you mean about holding the Dremel over the bushing covers, I've done the same and it heats up super quickly! I googled what a lap steel guitar is, awesome instrument!

Is the Air Scribe as loud as the electric one? Not including the compressor. Do you know of any compressors that are quiet? Love your work.

[@MamlamboFossils]

The air scribe is probably 2 or 3 times louder. There are quiet compressors but I don't know enough about them. I've built a little soundproof area in my garage

Great video, never knew you could prep a fossil with one of does cheaper scribes. Might try that for my trilobite

B72 paraloid

Man, i wish I lived somewhere with lots of fossils like NZ. Norway is mostly bedrock, and the very few places with fossils are either microscopic algae and stuff, or plants and shells that are illegal to collect privately. I would love to try my hand at prepping those crabs you seem to find everywhere you turn

[@askefantenthefool8050]

I work as a stonemason in Norways largest tombstone company, i found this channel today and are facinated about this. I guess i will look for rocks at shores now😅

[@valiantwarrior4517]

Thanks for the info! I’ve wondered about many of those things. Does the B72 affect how well the material separates from the fossil?

[@MamlamboFossils]

It does sometimes, it affects acid prepping quite a bit and can make it slower so you have to be careful with it.

[@Klara_Travelventure]

Thank you for the video, I have the same Dremel engraver and I am currently working on a sea urchin. What do you reccomend to seal the fossil after preparation to stabilize it? I would use super glue for glueing it together, but it migth be nice to seal it once it's done.

[@MamlamboFossils]

I would not add the b72 if not needed but if you're going to be handling it or if it starts flaking I would add a coating

[@bobs-rocks]

Cool. I found a gastropod that popped out of the host in our dry river bed. Did a short video on it with black light was nice.

[@dominikgietl5670]

Thanks for this video! I was thinking about getting into prepping for a long time but everywhere I searched for tips for beginner equipment I was told confusing conflicting info. With this demonstration I feel like I got a much clearer picture of what I am getting, if I were to buy this dremel - and I think I will buy it. What B72 paraloid solution are you using? I find solid pellets and different percentages and solvents online. Also: I have a few very delicate fossils from the Lagerstätten Solnhofen (very light brown limestone organised in thin horizontal plates) and some less delicate ones from Buttenheim (a clay pit). Do you have any specific recommendations/tips for equipment or technique regarding these fossils? Thanks in advance!

[@MamlamboFossils]

I use the solid pellets as well, I make a very dilute mixture - it you paint it on a piece of paper, it should evaporate very quickly and leave behind a thin layer of plastic.

[@dominikgietl5670]

@@MamlamboFossils Ah, thanks. Which solvent are you using? :)

[@robbybobby64]

An air scribe like the one you have pays for itself after the first or second fossil you do. Just for the comfort alone I wouldn’t do the dremel. Too bad it didn’t come with a flex shaft and had more power. Fatigue is disheartening. It took a time to build up the strength to work for longer periods of time. I just bought a new dremel and the flex shaft handle end is 25mm diameter. I like the thinner pen sized ones. I get cramps slightly from using this new one. I guess I will get used to it. Love your channel, peace out!

Hiya Jason, I put the B72 on if there are cracks in the crab as the air and vibration can cause it to break apart and fly off. It's being safe rather than sorry in my case. superglue is when something is already broken and needs fixing.

When it comes to half-mask respirators for longer sessions, I cannot recommend the 3M 4255+ enough. HUUUGE urestricted filter surface area w/ internal 1-way valves and good size exhale vent, so in terms of restriction you barely notice it's there at all, even doing hard manual labor. It super comfortable for a half-mask, very soft and conforming silicone against the skin, and in my experience it is among the best sealing half-masks if you have a beard. Minimal interference with glasses, headset, otger headgear (i'm just a sample group of 1 so can't say *_"NO_*_ interference)._ Does a good and clever job of collecting moisture from your breath ajs very easy to drain and clean, just "empty it out" before setting the mask somewhere "face" (filters) down. Oh and since the filters aren't canisters sticking out but sit fairly close to your face, I've found they don't leverage your head down/forwards x causing necknpain. And they're less in the way when in cramped space like under vehicles, inside ventilation etc. It's one of those "maintenance free" (aka, filters not replaceable) types, but I used one doing demolition and dry concrete work every day for over a year and didn't really notice any difference. The 4255+ id A2P3 rated, meaning protection against organics gases and vapors, plus dust/mechanical, oil and smoke/droplet/fog protection down to 99.95-99.99% effectiveness at 0.3 micron. Like a HEPA filter for your face :) Don't mean to sound like a frickin advertisement, I'm just a _very_ satisfied customer.
