I’ve been learning a ton of new skills from Pauls video’s, made a couple of dovetailboxes for my toolchest and came to the conclusion that some more clamps in smaller sizes will be handy.
I got six of the 1,2m sash clamps from silverline via bol.com but they are really expensive.
Unfortunatly I havent been able to find them in the local dutch stores.
The cheapest I managed to find online are these for €13,80, if I compare this to the once sold in the UK they are atleast 3-4 euro’s more expansive per clamp which will add up if you get a bunch of them.
Does anyone in the EU know of a place that sells these type of clamps for a cheaper price? Cant get them from the UK cause since brexit happend I’ll get charge extra to bring them into the EU.
And for my fellow dutchies, does anyone know where you can get denatured ethanol in the Netherlands? The Kruidvat and Etos stocks it but its like €2,40 for 110ml.
Bonus question, is there a way to search the forums? I tried google search but it rarely works and the search bar at the top right only searchs the blog pages.

I can help with the last question. You can limit google searches to the discussion forums by just using the google “site: “ limiter. ( the word “site” a colon, and the name of the site ( no spaces after site:)) the http part isn’t necessary. The search will be limited to that site section.
For example, this text string will get you all the listings in the discussion forums that include the text “sash clamp “
Sash clamp site:woodworkingmasterclasses.com/discussions/
To see the result, paste the above line into google search.
In the forums, all postings share the site name and /discussions/
For exact match, ( for example, if you wanted only the plural “sash clamps” , enclose the text before site: in quotes. This works for any google search.
To search the videos section of the site by name, the site search would be site:woodworkingmasterclasses.com/video-library
This is basically how the blog search works in limiting searches to that section.

I tried the google search before but it didnt work I guess I was using the wrong adress.
Your version does work.

If anybody from the Netherlands stumbles across this topic, I ended up buying Isopropyl alcohol from Degros and the sash clamps from gereedschap centurm.
For denatured ethanol, you might try asking at a specialist paint store or an artist supply store. (The latter will be pricey.)
I don’t know what the liquor laws are like in the Netherlands, but in some parts of the USA you can buy drinkable 190 proof (95%) pure grain alcohol in liquor stores. usually under the “Everclear” brand name. Some fussy woodworkers will use this to thin their shellac.

There is a alcohol taxes here on drinkable alcohol, comes down to €16,86 per percentage per 100 liter according to Wikipedia.
In practice its just to expansive to do. As mentioned I settled for Isopropyl alcohol which cost me €10,- for a liter excl. shipping.
I haven’t tried it out yet since all the local stores are closed cause of the lockdown and I’m still missing certain items I that I dont like buying online.
Thanks for the suggestions.
I’ve never heard of anyone using isopropanol as a solvent for shellac. I once spilled a little bit of rubbing alcohol (70% isopropanol) on an old shellacked surface and it did dissolve the finish. I’d be interested to no know how it works for you. I’d recommend experimenting with a small batch on scrap wood before you use this on a real project.
If this doesn’t work out, you might be able to get ethanol from a camping equipment supplier. It’s used as a fuel for some small backpacking stoves.

I’d be careful to read the SDS sheet on any camping fuel. Crown brand, for instance contains 65-70% Methanol, which is toxic, and 20-30% ethanol, and the rest isopropyl.
sLX brand is about 50-50%.
Isopropyl will work, but it dissolves flakes more slowly and evaporates more slowly than Ethanol. Your choice of 70% isn’t the best. The rest is water and can make the finish blush.
Pharmacies do sell 91% and you can get it online. Don’t pay extra for any that claims to be higher. I see 99% claims. That’s mostly ad hype.11 February 2021 at 8:44 pm #700839
Think there is another thread with a very similar subject. One of the contributors informed on having compared various solvents, with isopropylic alcohol being the slowest.
French polishing incidentally seems to have become popular shortly after the discovery on how to use activated carbon to produce 99% ethanol. Apart from being a bit expensive, it quickly becomes diluted as it absorbs moisture, taking it closer to 95%.

Finally got around to dissolving the flakes and applying it.
I made a 24g/100mL cut with 95% isopropyl. It dissolved completely in about 48 hours.
After 24 hours a sort of goo had formed at the bottom of the jar, you have to use a stick to stir it off the bottom or shake it really hard.
But once you’ve done that it will keep dissolving, you do have to shake/stir once in a while to get it off the bottom again.
Applied it to a dovetail box, my saws and a phone stand. I have to say it seems to work nicely. To bad the finish wasn’t great cause of my own incompetence, I made the rookie mistake of using it like a normal paint and going back and forth over it trying to fix mistakes and drips. But hey at least I didn’t blow up the house 😛2 March 2021 at 9:50 pm #703678
It might just be me of course, but it was first after having filtered the shellac that I had dissolved in isopropyl alcohol through a 125 micron lacquer filter that the mixture don’t leave a “lumpy” appearance. Before that filtering a desktop organiser for my goddaughter didn’t at all receive the finish I managed with a ready-mixed sanding sealer.

With the alcohol i can access easily here it takes 3-4 days to dissolve 50 gms in 200 ml of alcohol.
It gets to be the syrup on the bottom but does dissolve iin the end and stays that way.
Shakeing it every once in a while helps a lot.
I mix it in a jar twice as big as needed. So i really get a good agitate, when its all mixed i put it in a smaller jar with less air space. Probably dont need to but i do.3 March 2021 at 6:15 am #703723
Use 190 proof grain alcohol (95% alcohol/5% water). Isopropyl alcohol typically has too much water for use with shellac. Or use denatured alcohol (spirit) if you can purchase it.3 March 2021 at 9:34 am #703734
Another good source for isopropyl alcohol is a gasoline antifreeze Called ISO-HEET available at most box stores and every auto store and gas station..
The regular price is here around 17¢ an ounce, but is often on sale. Checking Amazon EU, I see it as low as €1,67 for340 ml. I also see it for ten times that, so shop.
The SDS lists it as containing 98.5% isopropyl alcohol. I’m sure it goes down rapidly when you break the seal, but that’s true for any alcohol you buy.
Here’s the SDS: https://www.imperialsupplies.com/sds-pdf/_s/ds/0055120_SDS.pdf
ISO-HEET comes in a red bottle.
A similar product just called HEET comes in a yellow bottle. That product pure methanol. Nasty stuff with all kinds of bad effects from exposure.
